HVAC Contractor Loses Thousands After Google Suspends Business Profile
A Washington HVAC company, NW Mechanical, says it lost between $300,000 and $500,000 in revenue after Google suspended its Business Profile listing. The listing, which had more than 100 reviews and a 4.5-star rating, was locked nine months ago, briefly reinstated in July 2026, then suspended again along with all its reviews. Revenue dropped 15 to 20 percent a month for six months, and the company laid off four employees. No reason was given for either suspension, though reviews appear to have been restored as of this month. This is a business-side story about how contractors get found online, not something that changes your home directly. But it is worth knowing about if you are searching for someone to install a heat pump, fix your furnace, or handle any other home upgrade. A company's Google listing and star rating are one of the main ways people find and vet local contractors, so a sudden gap in reviews or a missing listing does not necessarily mean a business is unreliable. It could reflect exactly this kind of technical dispute rather than any change in the quality of their work. If you are researching contractors for an energy project, it may be worth cross-checking a company through more than one source, such as word of mouth, a state contractor license lookup, or other review sites, rather than relying only on what shows up in a Google search that day.
For B2B companies, certifications lose their power in turbulent times like these
This is a business-to-business marketing story, not a home upgrade story, so it does not point to anything you need to do to your house or affect any rebate or program you might use. The gist: researchers studied how companies sell sustainability claims to other businesses. When markets are calm, having a certification like fair trade or organic helps close sales. But in turbulent economic times, that same certification stops moving buyers. What works instead is framing a product around reducing risk or exposure, or around clear financial savings and return on investment. Buyers under stress focus on protecting themselves, not on a seller's credentials. None of this changes how energy-efficiency rebates, tax credits, or program rules work for your home. Certifications and labels you might already rely on when choosing equipment or contractors, such as verified energy ratings, still mean the same thing they always did. This research is about how companies in business-to-business sales pitch sustainability to other companies, not about consumer programs, appliance labels, or home energy audits. If you're comparing quotes or products for a home upgrade, the practical takeaway is simply that a badge or seal on its own does not tell you much about savings. What matters for your decision is still the same as before: the actual cost, the efficiency numbers, and any rebate or incentive amounts tied to specific programs in your state. Nothing here changes eligibility, deadlines, or dollar amounts for home energy upgrades.
Vapor retarder needed?
This is a homeowner's question posted on a building science forum, not a news story, so there's no policy or program update to report. Someone renovating a 1973 home in Vermont is rebuilding their exterior walls with fiberglass or mineral wool insulation, rigid foam board on the outside of the sheathing, and a weather-resistant wrap, and asking whether they still need to add a special interior layer called a vapor retarder (a material that slows moisture from passing through a wall). The question draws on years of expert writing from the site's building science columnist, who has generally argued that adding an interior vapor retarder is often unnecessary, and can even trap moisture and cause problems, when a wall already has enough rigid foam insulation on the exterior side. That foam layer keeps the wall sheathing warm enough to avoid condensation problems, which is the main job a vapor retarder would otherwise do. The columnist has also warned that skipping the exterior foam without expert calculations, or installing a true vapor barrier (a stricter, less breathable material) on the interior of a wall that already has exterior foam, can cause trouble. For homeowners planning a similar wall upgrade, the takeaway is that pairing continuous rigid foam insulation on the outside of the sheathing with air sealing measures can eliminate the need for an interior vapor retarder in most cold climates, but the right approach still depends on how much foam is used relative to the total wall insulation and on local climate conditions.
Translucent Energy launches 1.2 GW solar module factory in South Carolina
A new solar panel factory is coming to Summerville, South Carolina. Translucent Energy is investing $15.6 million in the first phase of a plant that will make solar panels, with a total capacity of 1.2 gigawatts once running at full scale. The company expects to create 167 local jobs. Equipment is being tested now and should arrive in October, with the first panels shipping in December. In its first year, the factory aims to produce 600 to 800 megawatts worth of panels. For homeowners, the residential panels planned here are compact, higher-efficiency models rated at 450 to 470 watts, with efficiency up to about 23.5%. That's on the higher end for home solar systems, meaning fewer panels could cover the same amount of roof space compared to older, lower-efficiency models. The company says its supply chain is mostly U.S.-based, with some parts sourced from Turkey, which is meant to help solar projects qualify for a bonus under the Inflation Exchange Reduction Act (IRA) for using domestic content. That bonus can lower the cost of a solar installation for the entity that owns the project. The company also says this factory is the first step in a longer-term plan to build more solar components, including cells and wafers, in the U.S. rather than overseas.
Why Low Bid HVAC Can Become a High-Cost Problem
This piece is aimed mainly at commercial building owners, but the underlying warning applies to anyone comparing HVAC bids for a home: the cheapest quote can end up costing more once the system is running. A commercial sales manager at Mitsubishi Electric Trane writes that low-bid systems are often chosen using nominal lab performance ratings (like the 43°F benchmark in AHRI Standard 210/240) rather than the actual coldest or hottest temperatures a location sees. That mismatch can leave equipment undersized, which shows up as poor comfort during a cold snap or heat wave rather than at installation. He also flags two other shortcuts that cause trouble later: stripped-down controls that force manual adjustments during spring and fall, and treating "startup" (just confirming equipment powers on) as if it were the same as commissioning, which actually verifies a system was installed correctly and performs as designed. For heat pump systems in particular — including VRF (variable refrigerant flow) equipment that can heat and cool different zones at once — skipping careful setup can lead to costly failures, including compressor damage. For a homeowner, the takeaway is less about any specific rebate or deadline and more about what to ask for when comparing quotes: whether equipment was sized to your area's real winter and summer temperatures, whether controls are adequate for your home, and whether the installer confirms full commissioning rather than just a basic startup check.
California gubernatorial candidate pledges two hours of free power a day
California gubernatorial candidate Xavier Becerra has proposed giving residents up to two hours of free electricity a day, starting with low-income households. He estimates the plan, called "Power Hour," could save families about $1,000 a year by encouraging people to use power when the state's solar output is highest, often early afternoon, when so much solar energy floods the grid that prices can turn negative and excess power gets wasted. The idea borrows from Australia's "Solar Sharer" program, where millions of households can now get three free hours of midday power. But that program shows free power doesn't always mean lower bills overall: utilities often charge higher rates during other hours to make up the cost, so the savings depend on how much you can shift your energy use, like running appliances or charging an EV, into the free window. Households with home batteries or electric vehicles benefit most, since they can store cheap or free power for later use. Australia offers a 30% discount on home batteries; California already has its own battery incentive of up to $1,100 per kilowatt-hour for qualified households, plus a $3,500 rebate for first-time EV buyers. Becerra's plan is not law yet. If elected, he'd need to work with the state's utility regulator and utilities to design it within his first year. Energy experts are divided: some say it could make electricity prices better reflect real costs, but warn that fixed utility costs would still need to be covered somehow, possibly through higher prices at other times.
Extreme weather is changing how Americans see the world
A new nationwide survey from Gallup and the Walton Family Foundation finds that almost four in ten Americans now say they've experienced damage from extreme weather in recent years, a record high and up 5 percent from 2023. But the effect isn't quite what you'd expect: people who report storm or flood damage are more likely to say they feel "pushed by circumstances beyond their control" rather than feeling motivated to act. Among that group, 38 percent said they feel at the mercy of outside forces, 9 points higher than among people who haven't experienced a disaster. Oddly, this loss of a sense of control didn't change other attitudes. People who'd been through extreme weather were no more likely to want to move, no more or less confident their community was prepared for future events, and no different in their outlook on the future. The one thing that shifted was their sense of personal agency. The survey also found big regional gaps in who reports damage: 58 percent in the region covering Kentucky, Tennessee, Alabama, and Mississippi, versus just 24 percent in the Mountain West, even though nearly everyone in dry or hot regions has technically lived through drought or heat extremes. That suggests people mainly count "damage" when it's visible destruction, like a flooded home or downed power lines. For homeowners, the takeaway isn't about upgrades or rebates, but about a broader pattern: as extreme weather becomes more common, other research cited here suggests it tends to erode trust in government rather than spur people toward collective action or advocacy for stronger building or disaster policies.
750 Gigawatts Of Energy Storage, And Nowhere To Go — Yet
Battery storage for the power grid is booming, but the numbers show a big gap between plans and what actually gets built. Nationwide, about 750 gigawatts of storage projects are waiting in line for a grid connection — roughly equal to the output of more than 700 nuclear reactors. The typical wait for that connection is now five years, because the grid's aging infrastructure can't easily absorb new capacity. Research from Lawrence Berkeley National Laboratory found that of storage and power-plant projects that applied for grid connections between 2000 and 2020, only 13 percent were actually up and running by the end of 2025, while 75 percent were withdrawn entirely. Even with that bottleneck, storage keeps growing. Installed capacity is expected to nearly quadruple over the next six years, and manufacturing is expanding too: the South Korean company DeltaX just picked Monroe, Georgia, for a $141 million factory making batteries for grid storage. None of this changes anything about home energy upgrades directly, but it matters for context: more battery storage paired with solar and wind is reshaping the grid you draw power from, and slow grid-connection approvals are part of why some clean-energy projects near you may take years to come online. The related issue of grid reliability — including how data centers can suddenly disconnect and strain voltage across huge areas — is also part of the bigger picture utilities are wrestling with as they plan future upgrades.
VU-7 Brings New Flexibility to Commercial VRF
General HVAC Solutions America (formerly Fujitsu General America) has released a new commercial heating and cooling system called the Airstage VU-7. This is a variable refrigerant flow, or VRF, system — a type of setup that uses one outdoor unit to serve many indoor units, letting different rooms be heated or cooled at the same time. It's built for larger buildings, with capacities from 6 to 32 tons, so it's aimed at commercial properties rather than typical single-family homes. The system uses R-32 refrigerant, a lower-impact option than older refrigerants, and can work as a straightforward heat pump or as a "heat recovery" system, meaning it can move heat from one part of a building to another instead of just dumping it outside. It's rated to heat down to -15°F and cool up to 126°F outside temperatures, and it comes with efficiency ratings up to 25.25 IEER, 12.3 EER, and 12.5 SCHE — numbers installers use to compare performance, but the takeaway is that the company says it runs more efficiently than earlier versions. For most homeowners, this news is more about where commercial HVAC technology is headed than something to act on directly. But it's a sign that the same refrigerants and heat-recovery approaches showing up in larger buildings are becoming more common across the industry, and similar improvements often filter down into smaller residential heat pump systems over time.
4 Reasons the Southeast Should Pause the Data Center Gold Rush
A regional clean-energy group, the Southern Alliance for Clean Energy, is calling for an 18-month pause on new large data centers across Tennessee, North Carolina, South Carolina, Georgia, and Florida. Data center construction, driven by the boom in artificial intelligence, is expanding fast across the Southeast, and the group argues utilities are using shaky demand forecasts to justify building large amounts of new gas-fired power plants. Their concern for homeowners: utilities earn a guaranteed profit on new power plants and pipelines they build, and those costs get passed to customers whether or not the demand ever shows up. One study cited in the call found electricity bills in some parts of the region could rise by up to 57 percent by 2030. The group also points to more local effects: heavy water use for cooling, round-the-clock noise from generators and cooling towers near neighborhoods, and deals often negotiated under secrecy agreements before residents learn a project is coming. More than 70 counties, cities, and towns across these five states have already paused or restricted new data center development, including in North Carolina, Georgia, Tennessee, and Florida. This is a policy push, not a program you can sign up for. There's no rebate or deadline here for your own house. But if you live in the Southeast, it's worth knowing that data center growth is a factor utilities are citing when they ask state regulators for rate increases, and that fights over these projects and their effect on bills are playing out at local and state levels right now.
Just 10% of California’s EVs could provide 9 GW of grid power
A new report suggests that electric vehicles parked in California driveways could become a major source of grid power. If just 10% of the state's expected EVs enrolled in "vehicle-to-grid" (V2G) programs by 2036, they could supply about 9 gigawatts of electricity for 12 hours straight. V2G lets a compatible EV send power from its battery back into the grid when demand is high, then recharge later when electricity is cheaper, often during sunny midday hours when solar power is abundant. The idea is that EVs, along with home batteries, smart thermostats, and water heaters, could help California handle electricity demand without building as many new power plants or expensive grid upgrades. The catch is that the technology exists, but the programs to use it don't work well together. Rules, payment structures, and enrollment requirements differ from utility to utility, which makes it hard for EV owners to participate. The report calls for standardized programs and payment based on the actual grid benefit a customer provides, rather than a flat fee just for signing up. It also recommends paying participants less than the full value utilities save, so people without an EV or battery share in the savings too. None of this is available yet as a program you can join. It depends on your EV, charger, and utility all supporting V2G, plus interconnection rules that vary by location. But even simpler "smart charging," where your EV charges automatically during cheaper off-peak hours instead of during the evening rush, is already something some utilities encourage.
4 Reasons SACE Calls for 18-Month Moratorium on the Data Center Gold Rush
The Southern Alliance for Clean Energy is asking for an 18-month pause on new large data centers in Tennessee, North Carolina, South Carolina, Georgia, and Florida. The group says the region needs time to set rules for these projects before more get built, rather than dealing with the costs after the fact. SACE points to several concerns that matter for homeowners in these states. Data centers use tens of millions of gallons of water a day and bring noise and air pollution, often approved before nearby residents even know a project is planned. The group also warns that utilities are passing buildout costs on to regular customers, whether or not the predicted power demand actually shows up. In parts of the region, that could mean electric bills rising by as much as 57 percent by 2030. SACE argues this locks communities into decades of new fossil fuel power plants to serve data centers, with the financial risk falling on ratepayers rather than the companies building them. SACE's executive director, Dr. Stephen A. Smith, said a pause would let the region set rules on transparency, pollution, and cost before construction locks in outcomes that can't be undone. This is not a proposal for a permanent ban, but a temporary hold while state and local governments figure out how to handle the demands data centers place on power grids and water supplies. If you live in one of these five states, this is the kind of decision that could eventually show up on your utility bill, depending on how state regulators respond.
SIP diagnostic, repair/replacement guidance needed in WNC
A homeowner in western North Carolina built a small, 800-square-foot cabin using a prefab shell with structural insulated panels (SIPs) for the roof — factory-made panels with rigid foam sandwiched between two structural boards. They paid extra for a cold/winter barrier, but they're now seeing water drip lines running down several of the roof rafters. They believe the problem may trace back to how the builder installed the panels — possibly missing seals or strapping where panels meet. This is a real-world building question, not a program or policy update. The homeowner is asking the online community for help finding someone qualified to diagnose the leak, figure out whether it's a sealing failure, a strapping issue, or something else in the SIP assembly, and recommend repair or replacement. So far, local inquiries in their area have not turned up anyone able to help. For homeowners with SIP roofs or walls, this is a reminder that panel joints and seals matter as much as the panels themselves — moisture getting behind or between panels can show up as drips or stains well after construction, and tracking down the cause often requires someone with specific SIP diagnostic experience rather than a general contractor. If your own home has SIP construction, it's worth knowing this is a specialized enough issue that finding the right diagnostic help can take some searching.
Clean energy capital expenditures on track for $180 billion in 2026, reports Crux
A new report on clean energy financing points to some shifts worth knowing about if you're weighing solar, battery storage, or other home energy upgrades tied to utility-scale power trends. Federal tax credits that have supported wind and solar projects (the production tax credit and investment tax credit) lost broad eligibility after July 4, 2026, unless projects were already under construction by then and enter service by roughly 2030. That cutoff pushed developers to lock in over 170 gigawatts of wind and solar capacity before the deadline. For homeowners, the practical effect shows up in electricity pricing. With subsidies phasing out and financing costs rising, prices utilities pay for solar and wind power are projected to climb $15 to $20 per megawatt-hour, which can feed into what you pay on your electric bill over time. At the same time, battery storage is becoming a bigger part of the market, growing to help balance electricity demand, partly driven by data centers and AI computing needs pulling more power off the grid. None of this changes home rebate programs directly, but it reflects a broader energy market where storage and battery technology are gaining ground while some utility-scale solar and wind projects face higher costs and slower permitting. If you're considering a home battery or solar-plus-storage system, this growth in the storage market may mean more product options and competition ahead, even as the broader cost of electricity from the grid trends upward due to financing and subsidy changes at the utility scale.
Why plugging in all those EVs could actually save the power grid
Electric vehicles sitting in driveways could help solve a growing grid problem, according to a new report from the nonprofit GridLab, the grid software company Kevala, and the energy consulting firm E3. Many EV models come with vehicle-to-grid (V2G) technology, which lets a parked car send power back into the electric system when demand is high. The report found that if just one in ten California EV owners signed up for V2G programs by 2036, they could supply a third of the long-duration energy storage the state is aiming for — storage that would otherwise require expensive battery farms. The idea addresses a real strain on grids everywhere: more homes switching to electric heat, stoves, and cars, plus power-hungry data centers, are pushing up demand, while hotter summers mean more air conditioning right as solar power fades at sunset. EVs, which often sit idle and plugged in, could fill that gap. Owners who join a V2G program would set a time by which they need their car charged, so they wouldn't wake up to a dead battery. The report pairs this with "demand response," where a homeowner agrees to let a utility nudge their smart thermostat up a few degrees during a heat wave, trimming AC use during peak hours. If utilities get the payment amounts right — enough to encourage participation without overpaying — the savings from avoiding new battery infrastructure could keep electricity rates lower for everyone, whether or not they own an EV.
Sunrun and Voltus team up to offer megawatts to hyperscalers
Sunrun, which installs home solar and battery systems, is teaming up with Voltus, a company that bundles small energy sources into larger blocks of power, to sell electricity capacity to operators of AI data centers. The plan pools together thousands of Sunrun's residential solar-plus-battery systems in the PJM and MISO grid regions (covering much of the mid-Atlantic and Midwest) so that tech companies can get power quickly instead of waiting for new grid infrastructure to be built. Neither company said how much capacity the deal covers, or whether individual homeowners with Sunrun systems will see any payment or benefit for participating. This follows a similar move from Voltus in June 2026, when it signed a three-year deal with Google to supply up to 100 megawatts a year through the same program. Sunrun has also been active elsewhere: in June it partnered with Renew Home and Tesla on a much larger effort to coordinate over 16.8 gigawatts of home battery and solar capacity, and in July it launched a pilot placing small AI computing hardware inside homes with existing solar and battery setups. These deals reflect a broader trend of solar installers looking for new revenue as home solar sales have dropped sharply. Former Energy Secretary Jennifer Granholm noted that pooling home batteries can help data centers avoid costly grid upgrades, but questioned how much of that value will actually flow back to the households whose equipment is being used. For now, homeowners with Sunrun systems in the affected regions may already be part of these arrangements, though details on compensation have not been made public.
LGES opens second Michigan battery manufacturing plant, now makes 80% of ESS in North America
LG Energy Solution has started production at a new battery plant in Lansing, Michigan, its second facility in the state (the other is in Holland, Michigan). The Lansing site will make lithium-iron phosphate (LFP) batteries, a common battery chemistry, for energy storage systems used by utilities and businesses. It will also produce a different battery type, NMC, for electric vehicles built by Toyota in Kentucky. The company has put more than $2 billion into the site since 2022 and expects it to eventually employ 1,700 people, up from about 900 now. The plant was originally a joint project between LG and General Motors for EV batteries, but GM sold its share to LG in early 2025. This is mainly industry news about where batteries get made, not a program homeowners can sign up for. But it points to more domestic battery manufacturing, which could affect the supply and pricing of home battery systems down the road. LG Energy Solution plans to have more than 50 GWh of LFP battery-making capacity across North America by the end of 2026, spread across plants in Michigan, Ontario, Ohio, and Tennessee. By the end of this year, the company says 80% of its global energy-storage battery capacity will be based in North America. For homeowners considering a home battery for solar or backup power, this doesn't change anything immediately, but it's a sign that more of the batteries going into those systems may increasingly be made in the U.S.
Northwest council proposes 11 GW of new generation, 5 GW storage by 2032
A regional planning group, the Northwest Power and Conservation Council, has released a draft plan for how Oregon, Washington, Idaho, and Montana should meet growing electricity demand through 2032. The plan calls for building about 9 gigawatts of new renewable energy, 2.1 gigawatts of natural gas plants, and 5.2 gigawatts of battery storage, at an estimated fixed cost of $2.3 billion by 2032. The council expects electricity use in the region to grow roughly 50% over the next six years, driven largely by data centers in the near term and later by electric vehicles, buildings, and industry. For homeowners, this plan mostly shapes what kind of power plants and batteries get built in the region over the next several years, not anything you need to do at home right now. The plan avoids new gas plants in Oregon and limits them in Washington, due to state rules, with most new gas development expected in Idaho and Montana. It also pushes the Bonneville Power Administration, the federal agency that sells power from the Columbia River dams, to favor renewables and batteries over new gas plants where possible. The council will hold public hearings in all four states this September and October before finalizing the plan by early 2027. If you live in one of these states, this is the process that will influence your electricity supply and possibly rates in the coming years, though the draft does not include changes to homeowner programs, rebates, or bills.
Sunrun to Supply Voltus with Energy Capacity for AI Hyperscaler Agreements
Solar company Sunrun and energy platform Voltus have struck a deal to pool power from Sunrun's home battery and solar systems and sell that capacity to help supply electricity-hungry AI data centers. The systems involved sit in the PJM and MISO grid regions, which cover much of the mid-Atlantic, Midwest, and parts of the South. Voltus runs a program called Bring Your Own Capacity, which lets large power users like data center operators tap into flexible home devices — batteries, smart thermostats, and similar tech — instead of relying only on new power plants. For homeowners, the relevant detail is that participants get paid for letting their home battery or solar-plus-storage system be used this way. The companies say this kind of arrangement channels money into local communities and helps the grid handle demand spikes, which can reduce the risk of blackouts and, in theory, help keep energy costs down for everyone on the grid. This builds on a separate, larger effort by Sunrun, Renew Home, and Tesla to line up more than 16.8 gigawatts of flexible capacity from home batteries, solar, smart thermostats, and electric vehicles nationwide. No new rebate or incentive program is being introduced here — this is a business agreement between two companies, not a homeowner-facing offer. But it points to a growing trend: utilities and companies are increasingly looking to home batteries and solar systems as a source of grid power, which could shape what future compensation programs for home battery owners look like.
Geothermal has big potential. Here’s how states can help realize it.
Western states are ramping up support for a newer kind of geothermal power that can tap hot rock in more places than traditional geothermal plants, potentially supplying large amounts of round-the-clock clean electricity. A new report from the nonprofit Clean Air Task Force says states still need more coordinated policies before the industry can grow at scale, since high drilling costs, slow returns, and uncertain permitting timelines make these projects hard to finance. California has pushed utilities to buy power from "clean firm" sources like geothermal, which helped Fervo Energy's Cape Station project in Utah land a deal with Southern California Edison; part of that project is set to come online this fall. Colorado, Nevada, Texas, and other states have passed their own laws to speed permitting, clarify who owns underground geothermal resources, or fund geological surveys that help companies find good drilling sites. States like North Dakota, Arizona, and Washington are also working to make old oil-and-gas geological data easier for developers to use. None of this changes anything for a homeowner directly — this is about utility-scale power plants, not home heating or cooling systems. But it signals that geothermal electricity could become a bigger part of the power mix in western states in coming years, particularly as demand grows from data centers and electrification. The report's authors note that transmission access remains a major hurdle nationwide, and that no state has yet combined all the policies needed to fully unlock the industry's potential.
Hyundai unifies vehicle V2X capabilities with AllDayEnergy entity
Hyundai Motor Group is pulling together its electric vehicle charging features under one new name, AllDayEnergy, that will apply across Hyundai, Kia and Genesis vehicles. The idea is to give owners of any of these brands the same app experience for managing how their EV interacts with the power grid, rather than separate systems for each brand. The service starts with smart charging, which schedules your car to charge at certain times, sometimes at lower power, so you can take advantage of cheaper electricity rates and ease demand on the grid. Later, Hyundai plans to add bidirectional charging, meaning your EV could send power back to your house (V2H) or to the grid (V2G) instead of only drawing power in. Kia already sells a compatible wall charger for this from Wallbox, usable with the EV9 or EV6, though it requires an added grid disconnect switch. Hyundai has also said the Ioniq 9 will get V2H functionality in the U.S. AllDayEnergy will roll out first through Kia's app in the UK in the second quarter of 2026, with the U.S., Europe and Korea to follow, though no U.S. timeline has been given yet. If you own or plan to buy one of these EVs, this points toward more home energy features down the road, including possibly using your car as backup power. But U.S. rollout will depend on your local utility, since charging and backup rules vary by region.
Yet Another US Automaker Rushes Into EV Gap Left By Tesla
Several companies are moving into electric truck and van territory that Tesla has largely left open. The Detroit startup Grounded EVs, known for building electric RVs on Ford and GM van platforms, just raised $5 million in seed funding and is opening a 50,000-square-foot factory in Detroit. It will start making electric and gas-powered box trucks this month, aimed at businesses like food service, mobile healthcare, and public safety fleets rather than individual homeowners. On the pickup side, Ford's Fathom electric truck is set for volume production next year, Rivian is expanding with help from the Department of Energy, and Slate Auto and Scout Motors (part of Volkswagen) have electric pickups heading toward production. Tesla's Cybertruck, meanwhile, has struggled to catch on. Other companies are chasing medium and heavy-duty electric trucks: Harbinger is working with the Army on hybrid-electric resupply trucks, Workhorse Group landed a 100-unit order for its electric step vans, and Freightliner is pushing its own electric box truck. Tesla's long-delayed Semi truck has finally entered production with mostly positive early reviews. A California startup called Revoy has raised $27 million more (for $41 million total) for a swappable battery unit that retrofits onto diesel trucks. None of this points to a specific rebate or program for homeowners right now. But it signals that electric trucks and vans, in various sizes and for various uses, are becoming a bigger part of the vehicle market, which could eventually widen choices and lower prices across electric vehicles generally.
Canadian Solar says patent dispute with Maxeon is formally terminated
A patent fight between two solar panel makers, Canadian Solar and Maxeon, has ended. A U.S. appeals court dismissed Maxeon's patent infringement lawsuit against Canadian Solar, closing out the case for good. This follows an earlier ruling in January where a patent review board found that all of Maxeon's patent claims against Canadian Solar were invalid. The dispute centered on TOPCon solar cell technology, a common method used to boost how much electricity a panel can generate from sunlight. For homeowners, this isn't a rebate or program update, so it doesn't change what upgrades are available or what they cost right now. But patent disputes like this one can affect which companies keep making panels, how designs evolve, and how competition plays out among manufacturers, all of which shape the products on the market over time. Canadian Solar has been involved in several similar patent disputes in recent years, including past cases with Solaria and a settled dispute with Maxeon in Japan. Maxeon, meanwhile, has separate ongoing patent battles with another manufacturer, Aiko Solar, in the Netherlands and Germany. None of this changes anything homeowners need to do today. If you're considering solar panels for your house, this kind of industry news is mostly background: a sign that the panel manufacturing market remains competitive and sometimes litigious, but not something that affects pricing, incentives, or panel availability in any immediate way.
Beyond the home meter: How utilities can eliminate the EV ‘renter’s penalty’
If you own a home with a garage, charging an electric vehicle overnight is usually cheap. But if you rent or live in an apartment without your own charger, you likely depend on public or shared charging stations, where electricity can cost up to six times more than home rates. Two energy-equity experts argue this "renter's penalty" undercuts one of the main financial perks of owning an EV, simply based on where someone lives. Their proposed fix: utilities should stop tying affordability discounts to a home electric meter and instead attach them to the customer, so income-qualified drivers get the same discounted rate no matter where they plug in, whether that's a public charger or shared equipment at an apartment complex. Ideas on the table include discounts applied through a customer's account, prepaid charging cards, and reduced rates at utility-owned public or multifamily charging stations, sometimes combining these approaches. For most homeowners, this doesn't change anything directly, since home charging already comes at standard residential rates. But it matters if you have family members, tenants, or plan to move somewhere without dedicated home charging. It's also a sign of where utility policy may be headed as EV adoption grows: regulators are pushing utilities to make sure the savings of going electric aren't limited to people with driveways and garages. Whether your own utility offers anything like this depends on where you live, so it's worth checking your state's programs if this situation applies to you or someone you know.
The dual benefits of dual-use solar
Farmland near growing data center hubs is under pressure. Data centers can take up more than 1,000 acres each, and with over 1,700 new projects planned across the country, some landowners are being tempted to sell agricultural land to developers. But a growing alternative called agrivoltaics — combining solar panels with farming or grazing on the same land — is giving farmers a reason to hold onto their property instead. The appeal is financial. Leasing land for solar can pay farmers $1,000 or more per acre each year, according to one industry survey, often more than crops alone would earn, and with far more predictable income. Some solar developers are building this into their projects directly, adding sheep grazing beneath panels or designing systems that let crops keep growing underneath. In Texas, solar grazing businesses have emerged specifically to manage vegetation on solar sites using livestock, a practice that's expanding along with the state's solar capacity, now second largest in the country. Local and state policies are starting to shape how this plays out. Some farming-dependent counties have banned data centers outright, while others require solar projects on farmland to keep the land productive — through grazing, irrigation, or crop protections — before approving them. States including Massachusetts, New York, Maine, and Colorado offer financial incentives or tax breaks tied to farm-friendly solar. Virginia recently created a formal legal definition of agrivoltaics, aiming to balance its rising demand for data center power with keeping farmland in agricultural use. If you own farmland, what's available may depend heavily on your state and county rules.
Airstage System Offers Heat Pump, Heat Recovery Options
General HVAC Solutions America (formerly Fujitsu General America) has introduced a new commercial heating and cooling system called the Airstage VU-7. It's a type of large-scale ductless system known as VRF (variable refrigerant flow), which uses a single outdoor unit to send refrigerant to many indoor units, letting different rooms or zones be heated or cooled independently. This system can be set up either as a straightforward heat pump or as a "heat recovery" system, meaning some zones can be heated while others are cooled at the same time using the same equipment. The VU-7 uses R-32 refrigerant, a lower-impact option than older refrigerants, and comes in sizes from 6 to 32 tons. A 6-ton unit can connect to up to 16 indoor units, while the larger 24-ton-and-up models can support as many as 64. Indoor units come in several styles, including wall-mounted, ceiling-mounted, and slim ducted versions. The system is rated to work in outdoor temperatures as low as -15°F for heating and up to 126°F for cooling, and the company reports efficiency ratings up to 25.25 IEER and 12.3 EER. This is a commercial-scale product, sized well beyond what a typical house would need, so it's aimed at buildings like offices, apartments, or other multi-zone properties rather than single-family homes. Still, it reflects a broader industry shift toward heat pump and heat-recovery technology using newer, lower-impact refrigerants, a trend that is also showing up in smaller residential systems.
Enrolling 10% of California EVs in vehicle-to-grid programs by 2036 could deliver a third of the state’s energy storage goals
A new report on California's power grid looks at whether electric vehicles, parked in driveways across the state, could help store and supply power the way large battery plants do. The idea is called "vehicle-to-grid," where an EV's battery sends power back to the grid when needed, not just draws it while charging. The report, from research groups GridLab, Kevala, and E3, estimates California will have 9.7 million electric vehicles on the road by 2036, representing far more storage capacity than the state's planned large-scale battery projects. The authors calculate that if just 10% of those EVs took part in vehicle-to-grid programs, they could supply about a third of the storage the state is counting on from utility-scale batteries. They say this could happen without requiring EV owners to change their daily routines, thanks to smart meters and automated controls. For this to work, the report says utilities need better-designed programs. Past efforts have paid people just for signing up rather than for actual performance, or added new overlapping programs instead of fixing what wasn't working. The authors argue future programs should pay EV owners and other customers based on measured results and on the real value they provide to the grid, while also avoiding higher costs for other ratepayers. If your state or utility rolls out a vehicle-to-grid program, the compensation would likely depend on how it's structured under these principles, so the details of any future offer would matter for whether it's worth signing up.
Major data center bills advance in California despite industry pushback
California lawmakers are pushing two bills meant to keep new data centers from driving up electricity bills for everyone else. Senate Bill 886 would require the state's big utilities to make large data centers (25 megawatts and up) pay the full cost of the power plants and grid upgrades they need, plus a share of fees that fund wildfire prevention and other programs. It would also force these facilities to cut their power draw during grid emergencies, similar to rules being considered in Texas and other states. The second bill, SB887, offers data centers a faster environmental permitting process if they agree to run on 100% carbon-free electricity within five years, mostly from newly built sources, and use batteries instead of diesel generators for backup power during grid stress. Developers would also have to pay grid connection costs upfront and invest in the communities where they build. For homeowners, this matters because data centers use huge amounts of electricity, and utilities like PG&E are already planning for a massive increase in demand over the next decade. Supporters argue these bills prevent that cost from landing on regular ratepayers' bills, while PG&E and the data center industry warn the rules could slow down projects or raise costs elsewhere. Both bills are expected to pass the legislature this month, and Governor Newsom has until the end of September to decide whether to sign them into law.
Enphase shipping its 1st commercial batteries in 2027
Enphase Energy has opened pre-orders for its first commercial battery storage system, the IQ Battery C80. This is a large-scale battery, not the kind made for a typical single-family home. It stores 80 kilowatt-hours of energy and is built for multifamily buildings and larger commercial properties, with two versions: one for smaller multifamily or small-commercial sites, and a bigger one for large commercial or industrial buildings. The system pairs solar panels with battery storage using an all-AC design, meaning it skips some of the extra equipment (central inverters, high-voltage DC wiring) that other battery setups need. It can also connect to non-Enphase inverters, so it could work as an add-on for existing solar systems. The battery can scale up from 80 kilowatt-hours to 2 megawatt-hours for bigger projects, and it's built to support "virtual power plant" programs, where batteries in a building can send power back to the grid at times of high demand. It includes safety features like fire detection and an automatic shutoff to guard against overheating. For most homeowners, this announcement doesn't apply directly, since it's aimed at apartment buildings and commercial sites rather than single homes. It's worth knowing about mainly if you own or manage a multifamily property. Enphase says the batteries will be made in U.S. factories and come with a 15-year warranty, with shipments expected to begin in the first half of 2027.
One free app now puts 211,000+ EV chargers in one place
If you drive an electric car, a new free app called Octopus Charge is worth knowing about. It brings together more than 211,000 public EV chargers across the US and Canada into one place, so you don't need a separate app for every charging network. It works with 24 partner networks, including big names like ChargePoint, EVgo, Blink, bp pulse, Shell Recharge, and Circle K. The app, available on iOS and Android, lets you search for chargers by location or ZIP code and filter by charging speed, plug type, or network. It also shows which chargers are available right now, whether they're compatible with your car, how fast they charge, what they cost, and what's nearby. There's a built-in route planner made for EV trips, which can help with figuring out charging stops on longer drives. Octopus says the app is free to join and doesn't add any markup to the price each network already charges per kilowatt-hour. This is the North American version of a similar app, Octopus Electroverse, that the company already runs in the UK and Europe with access to over a million chargers in 40-plus countries. The US and Canada version is starting smaller, but with 211,000-plus chargers on day one, it already covers a lot of ground for anyone tired of juggling multiple charging apps on road trips or around town.
Researchers model 1,708 pathways for global PV waste recycling
A group of international researchers has built a large model looking at how the world should handle solar panel waste as panels reach the end of their life. The study ran 1,708 scenarios covering 32 regions, different recycling technologies, ways of trading waste across borders, and subsidy programs, to see which approaches save the most money and cut the most greenhouse gas emissions. The findings project that global solar panel waste could reach 297 million to 402 million metric tons by 2060, with China and other middle-income regions becoming major sources of that waste after 2040. Recycling this waste is not expected to become profitable on its own for more than a decade. The researchers also found a twist: rising prices for materials like silicon, silver, copper, and aluminum make recycling more valuable, but the same price rises can make new solar installations more expensive, which slows solar growth and means less waste to recycle later. The most cost-effective and climate-friendly approach, according to the model, combines local recycling know-how with shipping waste to regions best equipped to process it — potentially cutting billions of tons of carbon emissions and generating hundreds of billions of dollars in net benefits by 2060. But this approach also risks concentrating the financial and technological gains in a handful of wealthier, more advanced regions. The researchers suggest that subsidies which start generous and shrink over time, rather than staying flat, could spread those benefits more evenly without costing governments as much. This is early-stage modeling rather than a program homeowners can access directly, but it points to how solar panel recycling costs and benefits may shift over the coming decades.
The grid’s woes just got bigger in Texas
Texas Governor Greg Abbott recently paused new data centers from connecting to the state's power grid, giving regulators time to review the 474 gigawatts of proposed projects currently waiting in line. But the pause only applies to grid connections, not to data center construction itself. That distinction matters because it may push more data center developers to build their own private power plants instead of waiting for a grid hookup, a trend already happening nationwide. Going off-grid gets projects built fast, but it is expensive and inflexible: a facility running on its own generators has no backup if something breaks and no way to tap cheaper or cleaner power later. Most of these facilities are expected to seek a grid connection eventually anyway, once they need reliability or a better economic deal. The concern is that when they do, they will arrive already built and running, leaving the grid with none of the planning time it would normally get, plus equipment that may need costly rework to connect properly. That makes it harder to sort out who pays for what and increases the odds of the state overbuilding power capacity. For homeowners, this is mostly background noise on the fast-growing world of data center power demand, which is expected to double in Texas within five years. There is no direct action for you here, but it is a reminder that decisions about how huge, power-hungry data centers connect to the grid can shape electricity costs and reliability for everyone sharing that same grid.
The 2027 Toyota bZ is now on sale: Here’s how much it costs
Toyota's electric SUV, the bZ, is getting a 2027 update with prices staying about the same as last year. In the US, it starts at $34,980 (about $36,576 with delivery fees) for the base XLE front-wheel-drive model, which gets an EPA-estimated range of 236 miles. Paying more moves you up to longer range and more power: a Plus version reaching 314 miles, all-wheel-drive options with up to 338 horsepower, and a Limited trim with extras like 20-inch wheels, a moonroof, heated rear seats, and a digital rearview mirror. All models come with a NACS charge port built in, meaning owners can plug into Tesla Superchargers without needing an adapter, plus battery preconditioning for better cold-weather charging and a "Plug & Charge" feature that simplifies payment at charging stations. For anyone cross-shopping electric vehicles, this is mostly a story about incremental improvement rather than a big leap. The bZ was already one of the best-selling EVs in the US for the first half of this year, and the changes for 2027 are modest tweaks to features and pricing rather than a redesign. The new models start arriving at US dealerships in September. In Canada, the bZ starts at CA$45,985, with all-wheel-drive and Limited versions running higher. None of this points to a specific rebate or incentive tied to your home, but if you're weighing an EV purchase alongside home charging setup or upgrades, the bZ's pricing and range numbers give a useful benchmark for comparison against other electric SUVs on the market.
Einride to deploy 500 Tesla Semis in biggest electric truck order yet
Freight company Einride is putting 500 Tesla Semi electric trucks on the road, the biggest order for Tesla's electric semi so far. Deliveries start next month and continue in phases over 24 months, expanding Einride's electric fleet from about 250 trucks to roughly 750. The trucks will run in California, Texas, New Jersey, Illinois, and Georgia, hauling freight for Amazon. This is a trucking and freight story, not something that changes anything for a homeowner directly. But it points to the same math that applies at a smaller scale at home: electric vehicles save money on fuel and maintenance once you're driving enough miles to make the switch pay off. Tesla is betting that a large, concentrated customer like this makes it worth building out charging infrastructure, the same logic that applies to home charging and solar setups for electric vehicle owners. The financial details are murkier. The trucks likely cost Einride somewhere between $130 million and $145 million, but the company had only about $77 million in cash as of June. Einride says the deal is "fully financed with third party financing solutions" without naming a lender or terms. The company also touts $800 million in potential future revenue from the deal, but that figure describes pipeline business still being negotiated, not money already committed.
Holding the Line: Why Differential Pressure Is Critical in GMP Cleanrooms
This one is outside the usual territory for home energy upgrades. It's about air pressure control in pharmaceutical and biotech "cleanrooms" — the sealed, highly filtered spaces where drugs and sterile medical products get made. These facilities use precise air pressure differences between rooms to keep contamination out, and the article explains how HVAC systems (air handlers, sensors, and pressure monitors) keep that system running so drug batches stay safe and pass FDA inspections. None of this applies to a typical house. Homes don't need cascading pressure zones between rooms, and there's no rebate, product, or upgrade here relevant to home energy efficiency. The closest overlap is technical: your home's HVAC system also relies on airflow and pressure balance, but for comfort and efficiency rather than sterility. Sealing air leaks and balancing duct airflow matters for keeping conditioned air where you want it and keeping energy bills down, but that's a very different scale and purpose from what's described here. In short, this is industry and regulatory news for pharmaceutical manufacturing facilities, not something that changes what you'd do with your own home's heating, cooling, or ventilation system.
Oil Majors Double Profits in Europe in Latest Quarter
A new analysis from the environmental group Transport & Environment finds that eight major oil companies made €7.5 billion in extra profit across Europe in the first half of 2026, compared with the same period last year. Six of them — BP, Shell, Eni, Orlen, Repsol, and OMV — more than doubled their European profits in the second quarter alone, driven by oil price swings tied to unrest in the Middle East. The group is calling on the EU to make a windfall tax on these profits permanent, with the money used to help drivers deal with volatile fuel prices. This is a European policy story, not something tied to a specific home upgrade or rebate. But it points to a pattern worth knowing about: gasoline and diesel prices swing sharply with global oil markets and events overseas, and oil companies tend to profit from that volatility while drivers absorb the cost at the pump. The analysis found that countries with more electric vehicles on the road, like Denmark, are far less exposed to these price spikes than countries with fewer EVs, like Poland. For a homeowner, the takeaway is less about any immediate rebate or deadline and more about the bigger picture: heating and transportation costs tied to oil and gas remain unpredictable, while electricity-based options like heat pumps and electric vehicles are less exposed to these swings. There's no new program or deadline here to act on, just a data point on how oil markets are currently behaving.
To Disconnect or Not to Disconnect
As grid connection fees rise in Australia, some solar-and-battery homeowners are weighing whether to cut ties with the power grid entirely. One example: an electronics engineer named Anthony fully disconnected his house about a year ago. His setup includes roughly 14 kilowatts of rooftop solar, a large inverter, and two used electric-car batteries pulled from Tesla Model 3s, giving him enough stored power to run his home and charge his own electric car. Before disconnecting, he tested the idea by shutting off his grid connection for two months while monitoring his system, then called his retailers and had the metering equipment removed. So far, he has had no problems, and rising daily connection charges have made him feel it was the right call. Part of what made this affordable was buying batteries salvaged from wrecked electric vehicles for a few hundred to a couple thousand dollars, far less than a new home battery would cost. He also used solar and batteries to cut daily grid fees across a small block of rental flats, splitting the savings with tenants through slightly higher rent. None of this is a universal fix. Disconnecting means giving up the backup and convenience of grid power, and it raises open questions about how utilities and regulators might respond as more households do the same, including possible new fees for homes that stay connected. For now, this remains one homeowner's experience in Australia, not a documented option or program available elsewhere.
A House Shaped by Climate
A newly built house outside Quito, Ecuador, called Arrayanes House, shows how a home's shape and layout can handle heating and cooling without a furnace or air conditioner. The 5,000-square-foot house sits on a hillside lot next to a golf course, in a mild high-altitude climate. Its design relies on thermal mass (heavy materials like stone that absorb and slowly release heat), cross-ventilation, sun control, and a central courtyard to keep indoor temperatures comfortable year-round. The site's slope and the owner's wish for privacy, without a fence, shaped the layout. Architects built a long stone wall along the street-facing side of the house to block views from the road and golf course while keeping the home open on the inside. Behind that wall, the house opens onto a sheltered courtyard, and large operable glass walls surround that courtyard, letting in air and light while staying private from the street. The design places the house low against the sloped lot so it looks like it grows out of the land, rather than towering over it. While this project is in Ecuador, its approach is a useful reminder that features like thick walls, shaded openings, cross-breezes, and a protected outdoor space can reduce how much a home depends on mechanical heating and cooling, something worth considering in any climate with big swings between sun and shade or day and night temperatures.
ISO-NE to review ‘asset condition’ transmission projects under proposal filed at FERC
New England's grid operator, ISO-NE, has asked federal regulators to approve a plan giving it more oversight of "asset condition" projects — the power line and equipment replacement work that utilities plan and build largely on their own, mainly to swap out aging infrastructure. These projects have drawn complaints from states and consumer advocates because they get less scrutiny than other transmission spending, even though they make up a large share of costs on electric bills. In Connecticut, transmission charges account for about 15% of a typical bill, and asset condition work makes up 73% of transmission owners' annual capital spending in New England. Under the proposal, ISO-NE would review these projects and report on whether they're needed and cost-effective, starting Jan. 1. It would not have power to approve or block any project, but its findings could help states and advocates challenge utilities' bills later on. The move comes as New England utilities plan to add roughly $5 billion in asset condition projects by 2034, including about $1.3 billion next year. It follows a complaint over a roughly $360 million Eversource project in New Hampshire and a push from Sen. Richard Blumenthal, who also introduced a bill requiring federal regulators to weigh "affordability" when setting transmission rates. This is a policy and regulatory development, not something requiring immediate action from homeowners. But since transmission costs show up on electric bills, it's a sign that regulators are paying closer attention to a cost driver that has been largely invisible to ratepayers.
Beyond Charming
This story is a home tour, not an energy-upgrade piece. It covers the renovation of a 1920s lake cottage on White Bear Lake, near St. Paul, Minnesota, owned by Matt and Heather, who worked with David Heide Design Studio. The house started as an uninsulated summer cottage and had been added onto haphazardly over the decades, leaving it oddly proportioned and set awkwardly close to the street. The project began as a kitchen remodel but grew into a full renovation. The architects added a small entry porch to bring the front door closer to the street, built a new dormer over the kitchen porch to hold the main bathroom, and turned a former outdoor connector between the house and garage into an enclosed vestibule that acts as an airlock entry. Inside, designer Elizabeth Mueller worked with the homeowners on a colorful scheme using English greens, paprika red, and patterned wallpapers, with details like arched doorways, a new fireplace, soapstone counters, and furniture-quality bath cabinetry that nod to the home's 1920s and '30s character. There's no mention of insulation upgrades, air sealing, heat pumps, or rebate programs in this piece, so it doesn't offer anything actionable for someone weighing energy-efficiency work on their own home. It's really a design and renovation story about restoring character to an older house rather than a report on cutting energy costs or improving efficiency.
Apply now for the Trellis 30 Under 30 climate leaders 2026
This news is about a professional recognition program, not a home energy program, so it does not affect your house or any rebates you might be looking into. The item is a call for applications to the Trellis 30 Under 30 list, which honors young professionals working in climate-related fields such as carbon removal, renewable energy, industrial decarbonization and sustainability finance. Applicants must be 30 or younger as of October 1, 2026, and must show specific, measurable climate impact achieved through paid work between 2024 and 2026, not schoolwork. Applications are due September 11, with selections announced in October and candidates notified before the end of September. There is nothing here about heat pumps, weatherization, rebates, or any program a homeowner could apply for. It is simply an award list highlighting people working in corporate climate and sustainability roles.
Do heat batteries make sense for data centers?
A newer kind of battery is getting attention for powering data centers, though it has little to do with home energy upgrades. "Heat batteries" store electricity as heat in materials like carbon blocks or ceramic, then either release that heat directly or convert it back into electricity using equipment like steam turbines. Companies including Antora Energy, Tempo Energy, and Rondo Energy are pitching these systems to data center operators, who need large amounts of reliable power fast as demand for computing grows. Antora recently raised $550 million and, unlike in past funding rounds, emphasized data centers as future customers. The appeal is speed: Antora says it built a large storage system for a South Dakota biofuel plant in under a year, faster than many other options. The batteries can also discharge power for much longer stretches than standard lithium-ion batteries — up to 100 hours for Antora, and 12 to 24 hours for Tempo — which supporters say makes them a useful complement to lithium-ion systems already used for shorter bursts of grid power. Both companies say the materials involved are cheap and made domestically, which could mean lower costs and fewer supply problems, though no pricing details were shared. None of these companies have announced signed data center deals yet, and no one has built heat batteries at large commercial scale so far. For now, this is a technology aimed at industrial sites and power grids, not something homeowners would install or benefit from directly.
About $100 Billion Vanished After My Technology Warnings Were Public
This is a story about investing, not home upgrades, but it touches on technologies sometimes pitched as part of the energy transition. An analyst who has spent years warning that certain clean-energy technologies were overhyped looked back at his own public warnings and compared them to what happened to company stock prices afterward. He found that companies in hydrogen fuel, electric air taxis (eVTOL), and small modular nuclear reactors (SMRs, compact factory-built reactors meant to be cheaper and faster to build than traditional ones) lost roughly $100 billion in combined stock market value after his warnings were already public. Hydrogen companies account for the largest share, about $59 billion, based on a 2020 warning that hydrogen faced high costs and competition from batteries and direct electrification. SMR developers Oklo, NuScale and Nano Nuclear have lost $30.3 billion since peaking in October 2025, with X-energy adding another $5.8 billion in losses. None of this changes what rebates or tax credits are available for home upgrades like heat pumps, insulation, or weatherization (sealing up drafts and gaps in a house). Hydrogen, eVTOL aircraft and small nuclear reactors are not technologies homeowners install or buy into directly. The takeaway here is really about company valuations and investor risk, not about any change to home energy programs, equipment costs, or rebate eligibility.
CAISO’s load-balancing EDAM math doesn’t add up, says CPUC staff
This is a story about how California's power grid operator manages electricity markets across state lines, and it doesn't touch homeowners directly. Still, it's worth a plain explanation. California's grid operator, CAISO, launched a new regional electricity market in May that lets utilities in different Western states buy and sell power a day ahead of when it's needed. The idea is that sharing power across a bigger area saves money and keeps the lights on more reliably. But regulators at the California Public Utilities Commission say some of CAISO's numbers don't add up. They questioned why CAISO made large last-minute adjustments to how much backup power it required on two specific days, and asked CAISO to explain the math. A group of six California cities that buy power made a similar complaint, saying the market's cost to participants has been high while the benefits so far look small. A wholesale power trading company also asked for clearer accounting of who is actually paying certain grid congestion fees. None of this changes anything about your electric bill right now. It's a dispute among regulators, utilities, and grid officials over transparency in a wholesale power market that operates behind the scenes. If the market ends up working as intended, it could help keep regional electricity costs and reliability in check over time, but that outcome is still being sorted out. For now, there's no rebate, program, or rule change here that affects what you'd do at home.
Slab on grade addition adjacent to full basement – insulation and vapor barrier questions
A homeowner posted a question on a building forum about a small entry addition they're building next to an existing house that has a full basement. The original plan was to build a crawl space (a shallow unheated space) under the new entry, but the builder found a large, 12-inch-thick concrete shelf built into the existing foundation wall. It looks like it once supported a stone wall that's no longer there. Because of that shelf, the plan changed to a slab on grade, meaning the new addition's floor will be a concrete slab poured directly on the ground rather than sitting over a crawl space. The poster shared construction drawings and asked other builders and homeowners for feedback on two things: how to insulate the new slab properly, and where to place the vapor barrier, a plastic sheet used to keep ground moisture from moving up into the slab and the living space above it. These are common questions when a new slab-on-grade section connects to an older foundation with a basement, since the two structures handle moisture and heat differently. For homeowners not involved in this specific project, the situation is a reminder that additions built against older foundations sometimes reveal unexpected structural features, like this old stone-wall support, that can change the construction approach partway through planning. Getting the insulation and moisture barrier placement right in a slab addition matters for comfort and for preventing dampness problems down the road, especially where new and old foundation types meet.
EDP energy storage project joins existing California solar array
EDP Renewables North America has finished building a large battery storage system, called Sandrini Energy Storage, in Kern County, California. The battery system can hold 368 megawatt-hours of power and release it at 92 megawatts, and it sits next to an existing 300-megawatt solar farm, Sandrini Solar, that was already operating in the area. Battery storage like this lets solar power get saved up during the day and used later, including at night or when demand is high, instead of only being available while the sun is shining. The Redwood Coast Energy Authority, a local power provider, has agreed to use all of the battery's storage capacity and part of the solar farm's output. The project is expected to bring in $5 million in local revenue for things like schools, roads and emergency services, and it supported about 50 construction jobs. This news is about utility-scale power infrastructure rather than home equipment, so it does not involve a rebate or program a homeowner would apply for. But it's a sign that battery storage paired with solar is expanding in California, which can affect how reliable and available clean power is on the local grid. EDP now has over 1.2 gigawatts of wind, solar and storage capacity in the state, enough to supply power for more than 485,000 homes.
Earthjustice & Sierra Club Urge FAA to Keep Ban on Commercial Supersonic Flight
The FAA is considering lifting its 50-year ban on commercial supersonic flight over land, and two environmental groups, Earthjustice and Sierra Club, have filed comments urging the agency to keep the ban in place. The ban has been in effect since the 1970s to protect people on the ground from sonic booms, the loud shock waves supersonic planes create that can disturb people and wildlife for tens of miles on either side of a flight path. The groups argue that allowing supersonic flights would bring more than noise. Supersonic jets burn seven to nine times more fuel than regular planes and emit pollutants including sulfur oxides, black carbon, and particulate matter, on top of the carbon dioxide and other emissions all aircraft produce. Breathing in these pollutants has been linked to respiratory illness, heart disease, and cognitive problems in children. Aircraft emissions overall already account for 4% of U.S. climate emissions, and the groups say adding supersonic travel, largely for high-end customers, would make that worse without any real benefit to most travelers. This is a regulatory fight happening at the federal level, not something that changes anything about your house or utility bills right now. But it is a reminder that noise, air pollution, and climate emissions from transportation are all connected to the same kinds of environmental and health concerns that drive interest in cleaner, quieter home energy systems. If the FAA does roll back the ban, it could mean louder skies and more aviation emissions in communities under flight paths in the future.
Europe’s Banks Are Treating Hydrogen As A Niche, Not An Economy
European banks are drawing a hard line on hydrogen financing, and it says a lot about where the technology actually stands. In Belgium, a company called Power to Hydrogen has installed a commercial-scale electrolyzer (equipment that splits water into hydrogen using electricity) at the Port of Antwerp-Bruges. That's a real engineering step forward, but it mainly shows the equipment works, not that selling the hydrogen it makes is a good business. A clearer test came from Holthausen, a Dutch industrial gas company that's been around since 1945 and already had hydrogen production, fueling stations, and customers. When it asked for a loan to build bigger electrolyzers, ordinary banks, including its own, turned it down. Its hydrogen production had been losing money for years. Holthausen eventually got funding, but only by mixing in mission-driven lenders, development capital, and government support, not standard commercial debt. Meanwhile, the European Investment Bank agreed to lend Austria's OMV €450 million for a hydrogen plant tied directly by pipeline to its own refinery, which already uses and pays for hydrogen. That's the kind of deal banks like: a known buyer already in place, not hoped-for demand. The pattern suggests hydrogen is finding solid financial footing mainly in industries that already use it, like refining, not in the wider vision of hydrogen heating, fueling, or powering homes and vehicles. For homeowners weighing heating upgrades, this points toward proven options like heat pumps rather than hydrogen becoming a near-term choice for home energy.
Climate Change Is Happening, So Let’s Just Enjoy The Warmth! — Reform UK
A UK political row has broken out over climate policy after Richard Tice, deputy leader of the Reform UK party, said Britain should stop trying to fight climate change and instead "enjoy" hotter weather, suggesting warmer temperatures could even improve English wine. His comments came during a record-breaking summer in which UK temperatures topped 35°C (95°F) several times. The government estimates 2,877 people died from high temperatures during the May and June heatwaves alone, twice the toll from all of summer 2025, with costs to the economy put at roughly £4 billion. Health and farming groups pushed back hard. Nurses described hospitals hitting 36°C and corridors full of patients suffering heat-related illness. A new study in The Lancet, led by Stanford researchers, found older people are harmed by heat at lower temperatures than previously thought, and that far more people worldwide face "uncompensable heat stress," a condition where the body can no longer cool itself. Farmers are reporting one of the worst harvests on record, and wildfires have hit the Midlands, Wales, and Northern Ireland this year. Reform UK has also pledged to scrap the UK's 2050 net-zero target and end green subsidies if elected. For homeowners, this is a political and public-health story rather than one with a direct program or rebate attached. It's a reminder that extreme heat, drought, and wildfire risk are already showing up in ordinary British summers, and that the UK's broader climate and energy policy could shift depending on how this debate plays out.
How GE Supreme Silicone Protects Bathrooms for Years to Come
A Tennessee builder featured in a sponsored video explains why he relies on GE Supreme Silicone Kitchen and Bath Sealant for bathroom projects. Unlike acrylic or siliconized-acrylic caulks, this silicone sealant is fully waterproof, which matters most in the spots that get overlooked: where shower glass meets tile, around plumbing trim and shower flanges, beneath toilets, along countertop backsplashes, and around the base of freestanding tubs. The concern in each case is the same. Small gaps let water seep behind tile, under cabinets, beneath flooring, or into a subfloor, where it stays damp and out of sight. Over time that moisture can rot wood, damage a bathroom's structure, or grow mold. A tub base is a particular worry, since water damage there can undermine the support beneath something that holds a lot of weight. For a homeowner, the takeaway is less about this specific product and more about where bathroom water damage tends to start: not the big waterproofed shower pan, but the small joints and seams around fixtures, countertops, and glass that are easy to skip or let fail over time. If you have an older bathroom, cracked or peeling caulk around a tub, toilet base, or countertop backsplash is worth a look, since gaps there can let water reach places you can't see until the damage shows up as soft flooring, stained cabinets, or musty smells.
