The Pretty Good House Blog: Low Voltage Lighting
Low-voltage lighting is starting to show up as a whole-home option, running fixtures on stepped-down DC power instead of standard household wiring. The idea: one centralized power system feeds recessed lights, pendants, sconces, and even backlit mirrors throughout a house, using smaller wires and fewer of the bulky drivers (the devices that convert household voltage down to what a fixture needs) that older low-voltage setups required. The comparison being drawn is to LED bulbs, which went from an $18 novelty to a near-total replacement for old bulbs in about 15 years, cutting energy use and cost along the way. The suggestion is that low-voltage systems could follow a similar path, becoming a normal choice for lighting a home rather than a specialty product. This is early-stage industry news, not a finished product ready for typical homeowners to shop for. It comes from a builder describing preparation for his firm's first installation of this kind of system, in partnership with a passive-house builder, using equipment from a manufacturer called Cleanlife. There's no pricing, availability timeline, or rebate information here, and it's not yet something you'd bring up with an electrician for a standard remodel. If you're weighing lighting upgrades now, this doesn't change what's available to you today. It's worth knowing the concept exists, since whole-home low-voltage systems may become more common in new construction and major renovations in the coming years, similar to how LED bulbs eventually became the default.
Two big reasons to get a LEED credential this fall
This news is about professional certification, not something that changes your home directly. LEED is a green building rating system used mainly by architects, consultants, and builders to certify commercial and large residential projects as energy efficient. The update covers two changes to how people earn LEED credentials this fall. First, the entry-level LEED Green Associate exam now tests on the newest version of the rating system, called LEED v5, and gives results immediately after you finish. Second, the more advanced LEED Accredited Professional (LEED AP) exams, which show someone can guide a project through the certification process, are half off through October 21, with exams available through October 27. That discount also applies to retakes. For a homeowner, this mostly matters indirectly. If you are working with an architect, builder, or energy consultant on a major renovation, a LEED credential is one sign of their expertise in green building practices, including the kind of whole-house planning that overlaps with energy-efficiency upgrades. But this particular story is about professionals getting certified, not about new rebates, incentives, or products for your house.
In Savannah, Georgia’s utility regulators faced public wrath over data centers
Georgia's Public Service Commission, which sets electricity rates and oversight for Georgia Power, held a rare meeting outside Atlanta this week, traveling to Savannah at the urging of commissioner Alicia Johnson. The move let coastal residents speak up about a large OpenAI data center planned for nearby Effingham County. Many at the meeting pressed for more transparency about Georgia Power's contract with OpenAI, which is the largest deal for a single customer since the utility started reporting such contracts in 2024. Commissioners said their authority only applies if a data center signs up with Georgia Power, and pointed residents toward local elected officials for other concerns. Commenters also aired frustration over electricity bills, with one Sierra Club organizer asking the room if anyone thought their power was "reasonably priced." The answer was a firm no. PSC chair Jason Shaw, a Republican, said he agrees Georgia Power should share more unredacted information about its data center deals. For homeowners, this doesn't change any rebate or upgrade program directly, but it matters because the commission's decisions on data center contracts and rate increases shape what Georgia Power customers pay each month. Two Democrats elected last year have pushed back on rate hikes but remain in the minority. Two more seats are on the ballot this November, and if Democrats win both, the commission could flip to a Democratic majority for the first time in decades. Early voting begins October 13.
Tesla’s $10.1 billion Texas solar gigafactory clears key tax hurdle
Tesla is moving ahead with plans for a $10.1 billion solar factory in Fort Bend County, Texas, after a local school board approved a property tax break for the project. The Lamar Consolidated Independent School District voted 7-0 to grant the tax limitation under a Texas program called the Jobs, Energy, Technology and Innovation Act, which will cap the taxable value of the property for school funding purposes from 2029 through 2038. The planned facility, on a 3,050-acre site near Richmond, would make solar cells and wafers, not just assemble finished panels from imported parts, which is more common in the U.S. today. Tesla says the plant could employ nearly 9,700 people once running and create over 1,100 construction jobs along the way. Construction is set to run from 2026 to 2028, with production starting in early 2029. Tesla has also said it is weighing a site outside Texas, so this tax deal was one factor in keeping the project in the state. None of this changes anything about home solar costs or incentives right now. It is a manufacturing announcement, not a rebate program. But a large new domestic source of solar cells could eventually affect the supply and price of panels available to homeowners, especially if Tesla's broader goal of scaling up U.S. solar manufacturing capacity moves forward alongside projects like this one.
Trump's EPA decimated climate rules for power plants. What now?
The Environmental Protection Agency this week repealed the 2024 Carbon Pollution Standards, a set of Biden-era rules that would have forced fossil fuel power plants to cut or capture their emissions, or shut down. The move, announced by EPA Administrator Lee Zeldin, wipes out the last major federal climate rule covering power plants from both the Obama and Biden years. This doesn't mean the shift away from coal power stops. A similar pattern played out after Obama's 2015 Clean Power Plan was repealed under the first Trump administration: the U.S. still hit that plan's pollution-reduction target a decade early, because utilities kept retiring old coal plants in favor of natural gas and renewables. That kept happening largely because it's cheaper. Renewables remain the lowest-cost power option in the country, and keeping old coal plants running under federal orders has already added millions of dollars in extra costs for utility customers over the past year. For homeowners, this doesn't change anything directly about your electric bill or your house today. It does mean the pace of the shift toward cleaner power will likely depend more on economics and state-level decisions than on federal rules going forward. Separately, if you're in California, Gov. Newsom has bills on his desk that could affect utility rates and virtual power plant programs, and Massachusetts has expanded winter bill discounts for homes with heat pumps.
Vistra’s Moss Landing grid battery is on fire yet again
A grid battery plant in Moss Landing, California, caught fire again on September 18, a year and a half after a much larger fire wrecked the facility in January 2025. The plant, owned by Vistra, was once the world's most powerful grid battery, built inside a former gas turbine building south of Santa Cruz. That building and battery design turned out to be out of step with safety practices used elsewhere in the industry, and it fueled the 2025 blaze. Since then, Vistra has been tearing the plant down, pulling out battery modules by hand for recycling or disposal. Workers had already removed 34,000 modules and were working through the last 5,000, some of which may still hold a partial charge. County officials say the new fire involves batteries damaged in the earlier 2025 fire, and that it is smaller than that blaze, with hopes it will burn out within 24 hours. A shelter-in-place order is in effect for the surrounding coastal area. A neighboring PG&E battery site was not affected. For homeowners weighing solar-plus-battery setups or curious about grid storage news like this, the key point is that Moss Landing's problems trace back to an outdated design and battery chemistry that the industry has since moved away from. Newer grid batteries use safer lithium ferrous phosphate chemistry and are built in spaced-out, modular containers meant to contain a fire rather than let it spread, unlike Moss Landing's dense, reused industrial building.
China TOPCon solar cell prices fall for third week as export buying fades and wafer costs ease
Prices for solar cells made in China have dropped for three weeks in a row, as a rush of overseas buying tapers off and the cost of raw materials like silicon wafers and silver eases. Two common cell types tracked in industry pricing reports, TOPCon M10 and 210R, are now about 12% below their late-August highs, though still well above where they stood in early August. The earlier price spike was driven partly by buyers stocking up before new U.S. tariff measures (Section 232) take effect on Dec. 4. That rush has slowed as overseas warehouses fill up. At the same time, demand inside China has softened because a shift to market-based electricity pricing has made new solar projects less profitable than under the old fixed-rate system. China's cell production ticked up slightly in August but remains well below year-ago levels. For homeowners, this is mostly background noise for now: cell and wafer prices are one layer in the supply chain that eventually feeds into what solar panels cost, but there's no direct rebate, deadline, or program change here that affects your own home. The bigger price mover on the horizon is the U.S. tariff measure taking effect in December, which could push solar equipment costs up rather than down. Industry watchers are also eyeing a possible production-cut agreement among Chinese polysilicon makers, which, if confirmed, could tighten supply and firm up prices further into the fall.
Want to get off gas? Learn how at Drive Electric Month events across the US
If you have been curious about electric cars but haven't gotten around to test-driving one, this month gives you plenty of chances. Drive Electric Month, an annual event now in its 16th year, is running more than 150 events across most US states (and one in Canada) through late September and into October. The events are organized locally, so they range from small parking-lot meetups to large festivals with food, music, and dozens of cars on display. The idea is to let people talk directly with EV owners, rather than through a dealership, and to take test rides or drives. Local events cover a wide range of interests. Some focus on specific vehicle types, like RVs or trucks; others pair EVs with topics like using them as backup power during outages, or getting cheaper off-peak electricity rates from a local utility. A few, run through electric cooperatives, include information on rebates for buying an EV. If you can't find one nearby or would rather not go in person, there are online webinars in September and October covering EV ownership basics, charging, and getting money back through incentives. To find something near you, check the event map and list online, then look at each event's page for details on what will be there and how to RSVP or volunteer. Given how high gas prices have climbed lately, this is a low-pressure way to see what switching to an electric car might mean for your own driving and budget.
How this new startup plans to get data centers to pay for VPPs
A new startup called Resilience Energy wants to pay for home solar panels and batteries by getting data centers to foot the bill. The idea: data centers need more electricity, and instead of just building new power plants, they could fund equipment in homes that adds capacity back to the grid. In exchange, homeowners would get free solar and battery systems, and the data center gets access to that extra power. Resilience plans to work through large property owners, like state housing agencies and low-income housing providers, to sign up homes in bulk. The company says it already has interest covering more than 100,000 homes nationwide, though nothing has been installed yet and no customers are signed. Resilience wouldn't manufacture or install the equipment itself — it would partner with existing hardware and installation companies, then own the systems and arrange the financing and contracts with utilities and data centers. This is very early-stage: the company has raised $5 million so far and is still lining up its first deals in regions including the mid-Atlantic grid operator PJM and the Midwest grid operator MISO. If the model works, it could mean free solar and battery systems for households in certain communities, particularly those connected through housing agencies, paid for by nearby data centers rather than by the homeowner or utility ratepayers generally. For now, there's no program a typical homeowner can sign up for — it's a company testing a new way to finance home energy equipment, not yet a rebate or offer available broadly.
Watsco to Acquire HVAC Distributor The Granite Group
Watsco Inc., a major HVAC parts and equipment distributor, plans to buy The Granite Group, a plumbing and HVAC distributor with about $500 million in sales across seven Northeastern states: New Hampshire, Vermont, Maine, Massachusetts, Connecticut, Rhode Island, and New York. The Granite Group, founded in 1971 and based in Concord, New Hampshire, runs 82 locations serving roughly 11,000 customers with about 29,000 different products from more than 450 vendors. This is a business deal between suppliers, not a change to any specific product, price, or rebate program. The Granite Group will keep operating independently under its current leadership, including CEO Bill Condron, and the deal still needs regulatory approval before it closes. Watsco says the acquisition gives Granite more resources and scale to keep growing, including in the plumbing side of its business. For homeowners in the Northeast, this mainly affects the supply chain behind the equipment that contractors buy and install — it does not change what's on the market for your home right now. Watsco has been on an acquisition streak, having bought 73 HVAC and plumbing distributors since 1989, including Jackson Supply Co., a Sunbelt distributor with about $230 million in sales, back in June. These mergers can eventually affect which brands and products are most available in a region, but no immediate changes to local HVAC or plumbing supply have been announced.
The Iran war pushed countries toward clean energy — and coal
When the U.S. and Israel attacked Iran earlier this year, oil and gas shipping through the Strait of Hormuz nearly stopped, and fuel prices spiked in Europe and Asia. That price shock has pushed the world's energy use in two different directions at once. Some countries are burning more coal to make up for pricier oil and gas — the International Energy Agency now expects global coal use to hit a new record this year, reversing an earlier forecast of decline. At the same time, the high fuel prices have driven a surge in electric vehicles, solar, storage, and even nuclear power, as households and businesses look for cheaper alternatives. The net effect, according to a new analysis from Carbon Brief, is that global fossil-fuel emissions are still expected to dip slightly this year, mainly because oil demand is dropping faster than coal use is rising. China is the clearest example: even with more coal burned, the country's overall emissions fell because oil use for transportation dropped sharply as EV sales hit records. Similar EV surges have shown up in Australia, Indonesia, and parts of Europe. None of this changes anything about home energy programs or rebates directly. But it's a reminder that the shift toward electric cars, heat pumps, and home solar isn't just a local trend — it's accelerating worldwide, partly because fossil fuels keep getting more expensive and unpredictable. The coal bump is expected to fade once the crisis does; the new clean-energy equipment being installed now will not.
DERA LIVES! House votes to fund Diesel Emissions Reduction Act through 2029
This week the US House voted 343-79 to renew funding for the Diesel Emissions Reduction Act (DERA), a federal program that helps cover the extra cost of swapping older, heavily-polluting diesel trucks and equipment for cleaner replacements. The bill extends the program through 2029 and authorizes $100 million a year for it. It was sponsored by a bipartisan group of representatives and now heads to the Senate, then the President, before it can become law. This isn't a program homeowners apply to directly — DERA grants go to fleet operators, municipalities, and similar organizations, not individual households. But it's worth knowing about if diesel trucks, buses, or heavy equipment run through your area, since the program is aimed at cutting the pollution and fuel use tied to those vehicles. Over its two decades running, DERA has helped retire tens of thousands of dirty diesel engines and saved fleets more than 500 million gallons of fuel, which matters more given how high diesel prices have climbed lately. If you happen to operate a fleet or work with one, your state's EPA office can tell you more about how these grants work locally, since administration varies by state. For most homeowners, though, this is simply a sign that federal support for cleaner heavy-duty vehicles is continuing for a few more years, rather than something that changes what's available for home energy upgrades.
Utility-scale project roundup: Utah solar, Texas tech power, California microgrids and storage, and Massachusetts community solar
A batch of large power projects moved forward this month, mostly big-picture grid news rather than anything homeowners need to act on. In Utah, EDF Power Solutions locked in financing for a 300-megawatt solar farm that will send power across state lines to Los Angeles under a 30-year contract, helping California utilities meet clean-energy targets. In Texas, ENGIE agreed to supply up to 568 megawatts of wind power to Oracle for its data centers, part of the tech industry's push to run computing operations on carbon-free electricity. Closer to home for some readers, PG&E in Northern California awarded $30 million to six new community microgrid projects — local solar-and-battery systems that can keep the power on during outages — in Humboldt, Sonoma, San Mateo, Butte, Placer, and El Dorado counties. One project in Pescadero will pair solar panels with battery storage to keep nearly the whole town running for at least 24 hours during wildfire or storm shutoffs. PG&E has now opened applications for a third and final round of this grant program, open to local governments, tribes, and community groups. Separately, Arevon began major construction on a battery storage project in Daly City, capable of powering the equivalent of 321,000 homes during evening peak hours, with electricity going to community choice provider MCE. In Massachusetts, Northern Sun broke ground on two community solar-plus-storage projects in Swansea, using the state's SMART 3.0 incentive program, which is meant to expand access to shared solar power for residents who can't install panels of their own.
Hyundai warns the US may be next in line for a wave of cheaper Chinese EVs
This is car industry news, not a home energy upgrade story, but here's the gist for anyone weighing an EV purchase alongside other efficiency plans. Hyundai's CEO says the US could soon see a wave of cheap Chinese electric vehicles, similar to what's already happening in Europe. In markets without trade barriers, like the UK, Chinese brands such as BYD have grabbed over 15% of new car registrations, and BYD's cheapest model, the Dolphin Surf, starts around $25,000. In the US, a 100% tariff on Chinese EV imports currently keeps those low prices out, along with rules limiting Chinese-made batteries, minerals, and connected-vehicle software. President Trump recently suggested he'd consider allowing Chinese automakers in if they build vehicles in the US. Other US automakers, including Ford, have raised similar warnings about cheap Chinese competition. For now, both Hyundai and Ford are responding by pushing their own lower-cost EVs: Hyundai sells the IONIQ 5 starting at $35,000, Kia's EV3 starts at $29,890, and Ford plans a $30,000 pickup for 2027. None of this changes anything for homeowners right now. US tariffs mean cheap Chinese EVs aren't available here yet, so if you're weighing an EV purchase as part of a home energy upgrade plan, alongside things like a heat pump or rooftop solar, your current choices remain the mainstream brands already on the market. Any shift would depend on future policy changes, which haven't happened yet.
Chainsaw Retrofit, exterior insulation, & add on rafter details
This one is a homeowner forum post rather than a news story, so there's not much here that applies broadly. A homeowner is rebuilding the roof on a detached 20-foot by 20-foot garage after removing rotted rafter tails, siding, and roof sheathing. He's doing what's called a "chainsaw retrofit," a technique where old roof edges are cut back and rebuilt with new framing so thicker insulation can be added on top of and inside the roof and walls. His plan calls for roof insulation rated at R-26 on the outside layer plus R-23 on the inside, and wall insulation at R-6 outside plus R-15 inside, in a location on the border of climate zones 4 and 5. He's attaching new roof "sleepers" (framing strips that create space for insulation and let the roof surface be rebuilt) with long structural screws. He posted photos of his plan asking other builders to check his approach before starting work, and a building science expert who replied said the design looked good. There's no product launch, rebate news, or program change here worth passing on. It's simply one homeowner's insulation upgrade plan for a garage, useful mainly as an example of how exterior and interior insulation layers can be combined during a roof rebuild, not something that changes what's available to you or your own house.
Dry August pushes Dallas soiling losses towards 2% as North American GHI diverges
A dry August split the country's solar weather into two extremes. Sunlight levels, measured as global horizontal irradiance (GHI, the total sunlight hitting a flat surface), dropped sharply across the Upper Midwest and Great Lakes, where Indiana and Ohio had their wettest August on record. Chicago, Toronto, and Buffalo all saw well-below-normal sun. Meanwhile, Texas, Oklahoma, the Pacific Northwest, and Mexico got more sun than usual, with Texas and Oklahoma logging one of their five driest Augusts on record. Wildfire smoke in the Northwest and British Columbia also cut into sunlight there by 1-2%. For homeowners with solar panels near Dallas, the dry stretch had a downside: without rain to wash dust and debris off panels, modeled energy loss from dirty panels climbed toward 2% by the end of August, the highest late-August figure seen since 2007. The whole June-through-August stretch ranked as the second-dirtiest summer on record for the area, even though June started out clean thanks to frequent rain. If you own panels in a region that's gone unusually dry, this is a reminder that lack of rain, not just pollution or dust storms, can quietly reduce how much power your system produces. Hawaii also had a rough month weather-wise: Hurricane Lala made the islands' first direct hurricane landfall since 1992, bringing 90 mph winds, over 30 inches of rain, and widespread power outages. Despite the storm, monthly sunlight there ended up only 4% below normal since the flooding was brief.
Federal transit cuts could hit rural America hardest
Congress is working out a new transportation bill, the BUILD America 250 Act, to replace the 2021 infrastructure law before it expires at the end of the year. The new bill would put $16.5 billion less into public transit over five years than the old law provided, and every state would get at least $10 million less in federal transit funding over that time. Rural areas would feel this hardest, since small transit systems depend more heavily on federal money than big-city subway and bus systems do. Idaho could see the largest percentage cut in the country, at 18 percent, and Maine could see a 16 percent drop. In both states, transit officials say rides are already limited and local governments have little ability to make up the difference. Advocates warn that seniors and people with disabilities who rely on these services to get to medical appointments or leave the house could be hit especially hard. Indiana would see a similar cut, which could mean older, less reliable buses and longer waits for rural riders who already face weeks-long delays for reservations. Cities are not immune either — New York City alone could lose $2.3 billion over five years. Advocates argue that weaker transit service could push some households to rely more on cars, adding costs for gas, insurance, and repairs. If you live somewhere with limited bus or paratransit service already, this is worth watching, since the final funding levels for your state and county depend on what Congress decides in the coming months.
Efficiency Maine Annual Event Honors Contractors, Vendors, and Communities That Advance Maine’s Affordable Energy Objectives
Efficiency Maine, the state agency that runs Maine's energy-rebate programs, held its annual awards night in Freeport to recognize the contractors, vendors, and dealerships that help homeowners install efficient heating, insulation, and other upgrades. More than 130 electricians, plumbers, insulation installers, and electric vehicle dealers attended. These are the businesses listed as "Registered Vendors" or "Qualified Partners" on Efficiency Maine's website, which homeowners can search when looking for someone qualified to install a rebate-eligible upgrade. The agency also gave its first award for a battery distributor, reflecting a new push toward whole-home battery incentives alongside its usual heat pump and insulation programs. The evening's top honor, the Philip C. Hastings Award, went to the Penobscot Indian Nation for a two-year run of energy upgrades. Using more than $475,000 in federal recovery funds routed through Efficiency Maine, the Nation installed heat pump and cooling systems in its public works, police, fire, and elder care buildings. Separately, tribal members completed more than 25 home energy projects in 2026, including 24 whole-home heat pump installations, using Efficiency Maine incentives — the same kind of rebates available to other Maine homeowners. Officials at the event pointed to rising costs of imported oil and gasoline as a reason to keep pushing insulation and heat pump upgrades, and Maine's Public Advocate flagged energy storage and "grid-responsive" programs as a growing focus for the future. For homeowners, the practical takeaway is that Efficiency Maine's rebate programs, vendor network, and now battery incentives remain active and expanding.
Major US offshore wind farm installs its last turbine
Revolution Wind, an offshore wind farm off Rhode Island, has installed its last turbine and is expected to reach full power, 704 megawatts, later this year. The $6.2 billion project, built by Ørsted, has been sending some electricity to Rhode Island and Connecticut since March and will soon run at full capacity. It's one of only a handful of large offshore wind farms actually getting finished in the U.S. right now, alongside South Fork Wind near New York and Vineyard Wind 1 off Martha's Vineyard, with a few more due to wrap up over the next couple years. The project survived two separate attempts by the Trump administration to halt construction over unspecified national security concerns. Federal judges threw out both stop-work orders. The administration has since shifted tactics, offering to pay offshore wind developers to walk away from projects that haven't started yet, spending nearly $4 billion in taxpayer money on those buyouts so far, though the projects already under construction, like Revolution Wind, have gone forward anyway. For homeowners, this doesn't change any rebate or incentive program directly. But it does add power to the New England grid at a time when demand is rising. Offshore wind has already helped the region get through recent extremes, performing well during a winter storm and easing reliance on oil-fired power plants during a summer heat wave. More local, carbon-free generation like this can mean a steadier grid for homes in Rhode Island, Connecticut, and neighboring states.
Sierra Club Applauds Governor Abigail Spanberger’s Data Center Executive Order and Policy Framework Release
Virginia Governor Abigail Spanberger has signed an executive order aimed at reining in some of the environmental effects of data center growth in the state. Data centers, the large facilities that power cloud computing and AI, have been expanding rapidly and drawing criticism over their strain on electric grids, water supplies, and air quality. The order pushes for a move away from diesel generators (called Tier II generators) that data centers often use for backup power, since these produce heavy air pollution. It also calls for more opportunities for community input on new projects, incentives for data centers to use clean energy sources, and a ban on blanket non-disclosure agreements that have kept basic information about a facility's local impact hidden from residents. For homeowners, this mostly matters if you live near an existing or proposed data center, or in a Virginia community weighing whether to allow one. Data centers use large amounts of electricity and water, and that demand can affect local utility costs and grid capacity over time. The push for cleaner backup power and more public disclosure could mean fewer diesel emissions and more information available to residents before a facility gets built nearby. The Sierra Club's Virginia chapter praised the order as the strongest state action yet on data center pollution, while noting that further steps from the legislature and other officials would still be needed to address existing environmental harms. For now, this is a policy shift in Virginia specifically, not a nationwide change, so its direct effect depends on where you live.
Hitachi to double US production of small and medium-sized power transformers
Hitachi Energy is building a new $528 million transformer factory in Gallman, Mississippi, more than doubling its U.S. production capacity for small and medium power transformers. These are the devices that step electricity down to usable voltages as it moves through the grid to homes and businesses. The new plant will make transformers in the 10 MVA to 160 MVA range, built for voltages up to 230 kV, and will eventually take over production from Hitachi's existing Crystal Springs, Mississippi facility. Production is set to start in 2029. This is part of a larger $1.5 billion push by Hitachi to expand U.S. manufacturing, with additional capacity increases planned at facilities in Pennsylvania, Virginia and Tennessee. The company says the expansion is meant to ease industry-wide shortages of transformers, which have been in short supply as data centers, factories, and the broader shift toward electric appliances and vehicles push up demand for grid equipment. For homeowners, this isn't something requiring any immediate action, but it's worth knowing about if you've been told a home electrical upgrade, solar interconnection, or new heat pump or EV charger installation is delayed because a utility is waiting on a transformer. Those bottlenecks have been a real problem lately. More manufacturing capacity, once it comes online in a few years, could eventually help shorten those waits, though the new Mississippi plant won't start producing units until 2029.
NLR Campus To Host US Department of Energy Geothermal Center of Excellence
The U.S. Department of Energy has set up a new Geothermal Center of Excellence at the National Laboratory of the Rockies in Golden, Colorado, announced on September 3. The center is meant to speed up research and development of geothermal energy, which taps heat stored underground to generate power. It's led by the National Laboratory of the Rockies with support from the National Energy Technology Laboratory and expertise from nine other national labs, including Argonne, Sandia, and Lawrence Berkeley. This is a research and policy move, not a program homeowners can sign up for. The center's job is to work with industry and academic partners on technical challenges that stand in the way of scaling up geothermal power in the U.S., not to install or fund geothermal heat pumps in individual houses. An industry advisory board will help guide what research gets priority. For homeowners, this doesn't change anything about existing geothermal heat pump systems, rebates, or installation costs right now. It signals that the federal government is investing more attention and lab resources into geothermal technology broadly, which over time could improve the systems, costs, or grid power available where you live. But no dollar amounts, rebates, or dates that would affect a home purchase or upgrade were part of this announcement. Anyone curious about geothermal heat pumps for their own home should keep checking what incentives their state or utility currently offers, since those programs operate separately from this new research center.
What role will renewable energy play in the AI Energy Management Alliance?
Most people worry that the AI boom is going to push up their electric bill. A recent survey found 84% of U.S. adults are concerned about data centers driving up local electricity prices, and most want data centers to help pay for grid upgrades and rely on clean power. That worry is now shaping how the tech industry responds. Google, NVIDIA, and startup Emerald AI have launched the AI Energy Management Alliance (AEMA), a coalition that includes AI companies like Anthropic, utilities such as AES, Constellation, and National Grid, and energy developers including RWE and Fluence. The group's goal is to make data centers "power-flexible," meaning they can dial their electricity use up or down during times when the grid is under strain, rather than always drawing full power. Google says it can already shift a gigawatt of data center demand this way, working with utilities. The coalition also wants faster approval for connecting these flexible data centers to the grid, arguing this makes better use of existing power lines and equipment without raising costs or risking reliability for regular ratepayers. Part of the plan involves building solar and battery storage directly at or near data centers, rather than only through large offsite deals. One example is a Texas project pairing 750 megawatts of solar with 1.8 gigawatts of battery storage. For homeowners, this doesn't change anything directly, but it signals how the industry plans to handle the strain AI is putting on power grids nationwide, which affects electricity prices and grid reliability everywhere.
Toyota’s new electric SUVs are catching on, with nearly 5,000 sold in August
This one is about cars, not home energy upgrades, but here's what happened. Toyota's electric SUVs had a strong August, with the bZ model leading the growth. Toyota sold nearly 5,000 electric vehicles last month, up 35% from July, while total US electric vehicle sales rose 2.5% from July to about 78,895 units. That's still down nearly 47% from a year earlier, when buyers were rushing to claim a federal $7,500 EV tax credit that has since ended. The bigger trend worth noting is price. The average price for a new electric vehicle fell to $54,754 in August, narrowing the gap with gas-powered cars to under $5,000, or about 9.7%. Cheaper models like the Toyota bZ, Chevrolet Bolt, and Toyota C-HR helped pull that average down. The redesigned 2027 Toyota bZ now starts at $34,980 with up to 236 miles of range, or $37,980 for a version with up to 314 miles. Toyota also sells the smaller C-HR starting at $37,080 and the bZ Woodland starting at $45,380. If you're weighing an electric vehicle purchase alongside home upgrades like a heat pump or insulation, this suggests EV prices are inching closer to gas-car territory, which could matter if you're also planning to add home charging or pair an EV with solar or other electrification projects.
The fate of the Endangered Species Act rests on 2 simple words
The Trump administration has narrowed how the Endangered Species Act protects wildlife, and this doesn't fit the site's usual focus on home energy upgrades. Since it's outside that scope, here's a plain summary of what happened. The U.S. Fish and Wildlife Service now says it's legal to kill a federally protected animal if the death wasn't intentional. This follows an earlier change saying that damaging an animal's habitat no longer counts as "harming" it. Together, the two shifts weaken a law that's protected species like bald eagles, manatees, and the northern spotted owl since 1973, by removing legal consequences for industries whose logging, mining, or building activity destroys habitat or kills animals as a side effect. Legal experts expect court challenges. Nearly two dozen states have already sued over the changes, and the Supreme Court ruled in 1995 that damaging habitat does count as "harm" under the law, so the new interpretation contradicts decades of precedent. Species listed decades ago, like the Florida panther and California sea otter, could be most at risk, since they never got the added "critical habitat" protections given to more recently listed species and rely mainly on the broader "harm" and "take" language now being rewritten. This is a policy and legal fight over federal wildlife rules, not something that changes home energy programs or rebates. There's no action tied to this for homeowners.
FHB Podcast Segment: A Swedish Perspective on American Homebuilding with Tedd Benson
This is a podcast episode, not the kind of program or rebate news that changes what you can do to your house. In it, builder Tedd Benson talks with the Fine Homebuilding Podcast about his career, including starting Unity Homes during the Great Recession, and how ideas from Swedish building practices shaped decisions at that company. For a homeowner thinking about upgrades, this isn't a story about a new incentive, rule, or technology you need to act on. It's a conversation about business history and design philosophy from someone who has spent decades building homes. If you're curious about how European building approaches compare to typical American construction, or you want background on how one builder's company grew out of a tough economic period, the full episode is worth a listen. But there's no deadline, rebate, or program detail here that affects your own home or budget right now.
Where the Candidates Stand: Charlie Hatcher on Climate & Energy
This is a candidate profile rather than a home upgrade or rebate story, so it does not point to any direct action for your house. It covers Charlie Hatcher, the Republican running for Tennessee's Congressional District 5, and where he stands on energy issues ahead of the November 3 election. Hatcher, a veterinarian and former Tennessee Commissioner of Agriculture, is skeptical of federal support for renewable energy, saying he opposes subsidizing it "for a long period of time." He has not stated a position on climate change, electric vehicles, or data centers. He names energy costs, infrastructure, and food security as top issues for the district, and says he wants "responsible, common-sense investments" rather than more government spending on things like energy reliability, water, and roads. On affordability, he ties high energy costs to the price of groceries, manufacturing, and transportation, and says he'd work with the Trump administration to bring costs down. He also points to Tennessee's push to expand nuclear power as something he supports. None of this changes rebates, incentives, or programs available to homeowners right now. If you live in Tennessee's 5th District and want your utility bills and energy policy views reflected on the ballot, the registration deadline is October 5, early voting runs October 14–29, and Election Day is November 3.
Compressed-Gas Storage Demonstrators Got Bigger. The Economics Didn’t Get Better.
This is a story about grid-scale electricity storage, not something that touches individual homes directly, but it's useful background if you follow energy news or have solar and wonder about storage options beyond batteries. Compressed-gas storage systems work by using electricity to compress air, CO2, or liquefied air, storing it, then releasing it later to generate power again. Backers have built bigger demonstration plants over the past two years, including a 600 MW facility in China, a 500 MW project from Hydrostor moving through California permitting, a liquid-air plant under construction in the UK, and a CO2-based system in Sardinia. But bigger machines haven't translated into better economics compared with the two main alternatives: pumped hydro (which pumps water uphill and back down, and typically returns about 80 percent of the electricity put in) and lithium-ion batteries (whose prices have dropped sharply due to mass manufacturing). The compressed-gas plants, by contrast, return around 50 to 60 percent of the electricity used to charge them, while still requiring extensive excavation, pressure vessels, thermal storage, and other costly infrastructure that doesn't get cheaper just by building more of it the way factory-made batteries do. None of this changes anything about home energy decisions right now. It's simply a sign that batteries and pumped hydro remain the more proven, cost-effective tools for storing electricity at the grid level, while compressed-gas approaches remain niche and unproven at scale.
The Bronx will be breathing a little easier with new Volvo VNR Electric [update]
City Harvest, New York City's largest food rescue organization, has bought three all-electric Volvo VNR semi trucks to deliver food across all five boroughs, including the Bronx. The trucks produce zero tailpipe emissions and will also use battery-powered refrigeration units, so the coolers keeping food fresh won't burn fuel either. The purchase was funded by a $10 million award from the New York Clean Transportation Prizes program, aimed at cutting noise and air pollution in South Bronx neighborhoods near a busy freight corridor. These three trucks are part of a larger eight-vehicle deployment under the same program, supporting food distribution and waste hauling that moves more than 250,000 pounds of goods through the city daily. The trucks themselves run on a 565 kWh battery (a measure of how much energy the battery can store) feeding a 340 kW motor, and can haul up to about 82,000 pounds combined weight for up to 275 miles on a charge. Charging will eventually be handled by a new public charging hub at the Hunts Point Food Distribution Center, built by MN8 Energy, with 32 fast chargers for heavy trucks plus 10 slower Level 2 chargers when it opens in 2029. For homeowners, this doesn't come with a rebate or program to sign up for. It's a local example of heavy delivery trucks going electric, which over time can mean less diesel exhaust and noise in neighborhoods near freight routes.
Microsoft ‘preserving its ability’ to challenge data center transmission costs decision
In Virginia, regulators recently ordered Dominion Energy to make large data centers pay directly for certain transmission costs, rather than spreading those costs across all customers. This came after the Virginia State Corporation Commission ruled in July that Dominion must require a mandatory upfront payment (called a "contribution in aid of construction") from data centers for the substations and transmission lines built specifically to connect those facilities to the grid. Dominion has until October to file its detailed plan for how this will work. Microsoft has now filed a notice with the Virginia Supreme Court that keeps its option open to formally appeal this decision, though a company spokesperson says Microsoft has not filed an appeal yet. The company says it wants to make sure any final rates are "transparent, fair" and reflect what each customer actually costs the system. Microsoft has until late November to decide whether to move forward with a full appeal. Other tech companies involved in the case, including Google, have taken a different stance — Google has said it's comfortable with mandatory payments for direct connection costs, as long as those costs are clearly separated from broader grid upgrade costs. For homeowners, this dispute matters because it's part of a larger fight over who pays for the electric grid upgrades that massive data centers require. If regulators succeed in requiring tech companies to cover more of these specific costs themselves, it could reduce the amount that gets passed along to residential ratepayers on their electric bills.
EVE Energy signs 206 GWh battery framework with storage supplier Fluence
Two big players in the battery world have made a large, long-term deal, though it's more about industrial supply chains than anything homeowners will see soon. Chinese battery maker EVE Energy has agreed to supply U.S. storage company Fluence with up to 206 GWh of batteries between 2027 and 2031. The first firm commitment is 16 GWh in 2027, with another 190 GWh reserved for the following four years. Fluence builds the large battery systems that utilities and grid operators use to store electricity, not the kind that goes into a home battery setup. The deal is a framework agreement, meaning the two companies still need to work out specifics like pricing, battery chemistry, and delivery schedules through future orders. EVE itself cautioned that policy changes or market shifts could affect how much of this actually gets built. Fluence, meanwhile, has had recent troubles: it recently cut its 2026 revenue forecast due to production delays and supply problems at its U.S. manufacturing operations, and disclosed $15 million in costs tied to setting up this kind of international supply deal. For homeowners, this news mostly signals how tangled global battery supply chains have become, with U.S. tariffs and sourcing rules increasingly shaping which countries' batteries end up in American energy storage projects. It doesn't point to any near-term change in home battery prices or availability, but it's a sign of how much of the battery storage that powers the electric grid — and eventually helps support things like home solar and EV charging — depends on deals like this one working out as planned.
Texas records suggest OCI is bringing Elite Solar to Mission Solar Energy manufacturing site
Mission Solar Energy, a longtime U.S. solar panel maker in San Antonio, Texas, has hit a rough patch. The company, owned by South Korean firm OCI, has mostly supplied panels to homeowners and residential installers. But its president told federal trade officials that cheap solar cell imports from India, Indonesia and Laos have undercut its prices so badly that the plant went from more than 200 workers to 70 by 2025, and has now temporarily stopped manufacturing altogether. That trade case is part of a broader federal investigation into unfairly priced solar imports. At the same time, new construction filings suggest a turnaround may be coming. Mission Solar had built a large warehouse addition years ago as part of a plan to expand to 1 gigawatt of panel-making capacity, a plan that stalled. Now, permit filings show $15 million earmarked to convert that warehouse into a factory for Elite Solar, a Singapore-based panel brand with ties to OCI, with construction starting in October and finishing by June 2027. For homeowners, this doesn't change anything immediately about buying panels or getting rebates. But it's a reminder that where solar panels are made, and whether that production stays in the U.S., can shift quickly. If you're comparing panels for a home installation, brands and manufacturing locations tied to this Texas facility could look different in a year or two.
BMW begins iX3 deliveries early in the US as demand surges
This is car news, not a home energy upgrade story, but here's what happened for anyone curious. BMW has started delivering its new electric SUV, the iX3, to US customers earlier than planned. Deliveries were originally set to begin September 25, 2026, but dealers were told to start on September 16 instead, due to strong demand. BMW says the car has racked up more than 100,000 orders worldwide, and the company has added a third production shift at its plant in Debrecen, Hungary, to keep up. The 2027 BMW iX3 50 xDrive starts at $61,500 and has an EPA-estimated range of up to 434 miles. It can charge at up to 400 kW, adding 231 miles of range in as little as 10 minutes. Inside, it uses BMW's newer interior design, with a 17.9-inch central touchscreen and a 43-inch display that stretches across the base of the windshield. None of this touches home energy upgrades, rebates, or weatherization programs. If you're weighing an EV purchase alongside home electrical work, like adding a charger or upgrading your electrical panel, this is simply a note that a new higher-end electric SUV is now arriving at US dealers sooner than expected, with strong demand behind it.
Jackery SolarVault 3 Shows Potential To Scale From Balcony To Whole Home
Jackery showed off a new home battery system, called SolarVault 3, that's built to grow with you. Instead of buying one big battery upfront, you start small: a couple of solar panels and a 2.52 kWh main battery module, which cost a few hundred euros for the battery alone or a little over a thousand with panels. From there, you can add more 2.52 kWh expansion batteries yourself, no professional installer needed, as your needs or budget change. The panels are lightweight and flexible, and some versions work bifacially, meaning they capture light from both sides, so they perform better even when they're not angled perfectly toward the sun. The system can plug into a standard wall outlet to charge, and it can also pull in solar power directly. On the German market, output is capped at 800 watts when connected to the grid, though it can supply more when running independent of the grid. For those who want more capacity, Jackery also showed a combined setup linking three of these balcony systems together with a separate hub, pushing total storage up to 45 kWh, enough for many homes, and coordinated by software that manages energy use automatically. This system is aimed at renters or first-time homeowners who want to ease into battery storage rather than commit to a large, expensive, professionally installed system right away. It's designed to last more than 15 years, comes with a 10-year warranty, and can move with you if you relocate. Pricing and availability details beyond what's noted above were not specified.
Driven to Serve: How Taylor Searcy Turned Navy Service into Clean Energy Strategy at GM
This is a profile of Taylor Searcy, a Navy veteran who now leads clean energy strategy at General Motors, overseeing the power used at the company's factories and offices. There's no new program, rebate, or deadline here, but one detail is worth knowing if you own a GM electric vehicle: GM has developed bidirectional charging technology that can turn a compatible EV into a home backup generator during an outage. GM calls this "the grid in your garage." The catch is this isn't automatic. GM notes it requires a V2H-capable (vehicle-to-home) EV, a specific GM Energy charger and enablement kit, a properly wired home, and approval from your utility to connect to the grid this way. How long the car can power your house depends on the battery's charge, the weather, and how much you're running at the time. It's also not meant to run medical equipment. The rest of the piece covers Searcy's path from Navy officer to sustainability work, including GM's claim that it matched 100% of its U.S. electricity use with renewable energy in 2025, a first for a U.S. automaker. That's a corporate milestone about how GM powers its own operations, not something that changes rebates or programs available to homeowners. If you already own or are considering a GM EV, the bidirectional charging feature is the detail with any real relevance to your house, and it's worth asking a dealer or GM directly which vehicles and equipment currently qualify.
144 Tesla Megapacks power Australia’s first 8-hour grid battery
Australia has switched on its first eight-hour grid battery, built from 144 Tesla Megapacks at RWE's Limondale site in New South Wales. Most grid-scale batteries today discharge for only one to four hours. This one holds enough for a full eight, letting it soak up cheap midday solar power and release it slowly through the evening and into the night, when demand is highest and solar output drops off. The design is unusual: the battery charges roughly twice as fast as it discharges, filling up in about four hours during the sunniest part of the day, then stretching that energy out over eight hours. Sitting next to an existing solar farm, it's meant to smooth out the classic problem solar-heavy grids face — too much power at noon, not enough at dinnertime. The project was backed by a New South Wales government program that guarantees revenue for long-duration storage, and two more similar eight-hour batteries are already planned in the state. This is a utility-scale project, not something that changes what's available for a home battery system. But it points to where grid technology is headed: longer-duration storage that can carry solar power further into the evening, potentially easing strain on the grid during peak hours. For homeowners with solar panels or considering a home battery, the same basic idea applies at a smaller scale — storing cheap daytime solar to use later when rates or demand are higher.
Discounts on Kia EV9 Give It Ridiculous Price
Some dealers are cutting deep discounts on the Kia EV9, a large electric SUV that seats up to seven. In Texas, one dealership dropped the EV9 Light RWD from its $54,900 starting price to $41,414 — a $16,041 cut. That version has 230 miles of range, which covers most daily driving even though it's on the lower end for an electric vehicle. Other dealers are matching the trend. In Illinois, a Light Short Range model fell from $57,480 to $42,480, and a Light Long Range version — with 304 miles of range — dropped from $59,785 to $44,785. These prices put a full-size, seven-seat electric SUV in the same range as much smaller electric cars like the Tesla Model 3 or Kia Niro EV. For a homeowner comparing vehicles, the appeal isn't just the sticker price. An electric SUV like this typically costs less to run than a similarly sized gas SUV, since electricity is generally cheaper than gasoline per mile and electric motors need less maintenance. If your household already has home charging or is thinking about installing it, a discount like this could make a three-row electric option more affordable than expected. Sales of the EV9 are already up 12 percent this year compared with the same period last year, suggesting other buyers are taking notice of the price cuts too. Discounts vary by dealership and location, so what's available will depend on where you live and which dealer you check.
Where the Candidates Stand: Chaz Molder on Climate & Energy
Chaz Molder, the Democratic candidate for Tennessee's Congressional District 5 and current Mayor of Columbia, has laid out some positions on energy that could matter to Tennessee households, though his campaign hasn't addressed every topic. He supports steady federal backing for renewable energy, arguing that consistent policy helps the private sector innovate and can lower costs while making the power grid more reliable. He also counts nuclear power among the low-carbon resources he thinks Tennessee needs as electricity demand grows. On electric vehicles, Molder has championed new fast-charging stations in Columbia, saying they support EV growth and a cleaner future for the region. Affordability is a stated priority of his campaign, with a general pledge to lower everyday costs for Tennessee families, farmers, and seniors, though no specific energy-bill proposals are detailed. Molder has also weighed in on data centers, a growing issue for utility customers. He backs a temporary pause on new data center approvals in Memphis and Columbia until communities get clearer answers about effects on electric bills, air quality, and neighborhoods. He's also voiced support for the Tennessee Valley Authority's move to charge data centers higher rates specifically so the infrastructure needed to power them isn't paid for by regular TVA customers. That stance could be relevant if you're a TVA customer, since it affects who covers the cost of new power infrastructure. His views on climate change and energy justice haven't been confirmed in public statements or on his campaign website.
Google-backed pilot unlocks first environmental certificate revenue stream for battery storage
A pilot project backed by Google has tested a new way to pay for grid batteries: selling the "shift" of clean energy from when it's generated to when it's actually needed. Companies like Quintrace, esVolta, and LevelTen Energy ran a three-month test using two large battery projects in the west, storing surplus solar power at midday and releasing it during evening demand peaks. In total, the batteries shifted 9.2 gigawatt-hours of clean energy across different hours of the day. The idea addresses a mismatch in how companies currently claim "clean energy" use. Most corporate renewable energy deals are tracked on an annual basis, but batteries work hour by hour. As tracking standards move toward requiring hourly proof of carbon-free power, this pilot created a system to verify, hour by hour, how much clean energy a battery actually stored and delivered, accounting for the small losses that happen during charging and discharging. Google paid for this "time-shifting" service directly, without taking on the operational risks or long-term contracts usually tied to battery projects. This isn't a program homeowners can sign up for — it involves utility-scale batteries and corporate energy deals, not home solar or battery systems. But it points to a broader shift in how battery storage gets valued and paid for. If this kind of hourly clean-energy accounting becomes standard, it could eventually shape the incentives and market rules that affect home battery and solar programs too, though nothing here changes the rebates or credits currently available to individual homeowners.
Podcast Episode 755: A Talk with Tedd Benson at the FHB Summit
This week's Fine Homebuilding Podcast features a conversation with Tedd Benson, a longtime timber-frame builder, recorded live at the 2026 Fine Homebuilding Summit. Host Ben Bogie talks with Benson about his path into home building, which started when moving his own family from a poorly built house into a well-constructed one changed how they lived. Benson also discusses how he grew his building businesses over the decades and why he thinks innovation matters for the construction trade going forward. The episode is more of a career retrospective and industry conversation than a how-to guide. It touches on the values behind good building rather than specific products or techniques, so there isn't a project or rebate tied to this one. Still, the underlying idea, that a well-built house can genuinely change how comfortable and livable a home feels, is worth keeping in mind if you are weighing bigger upgrades to your own place. If you want to hear the full discussion, it runs a little over an hour and is available wherever the Fine Homebuilding Podcast is posted. It is part of the site's ongoing series of weekly episodes on building, remodeling, and design, aimed at anyone curious about the craft and science behind home construction, not just professionals in the trade.
Volkswagen’s EV van drove through 92 countries to set a new Guinness World Record
A Volkswagen ID. Buzz, the electric version of VW's van, just set a Guinness World Record for the most countries visited in a continuous journey by a battery-powered vehicle. Driver Rainer Zietlow took the van 99,767 km (about 62,000 miles) through 92 countries over 445 days, crossing six continents from Germany through the US, Africa, South America, the Middle East, Southeast Asia, Australia and China. The trip required more than 300 charging stops and 16 container ship crossings, but the van had no technical breakdowns along the way. After the journey, testing group TÜV Nord checked the van's battery and found it had retained 95.75% of its original capacity, a sign that heavy long-distance use didn't wear it down much. Zietlow said the trip showed real advantages over a gas or diesel van, since he avoided problems like fuel contamination, oil changes, and engine overheating that can come up in rougher parts of the world. He expects electric vehicles to keep closing the gap with gas engines as batteries and fast-charging improve. This isn't a story about a new rebate or product homeowners can buy, and it doesn't have anything to do with home energy upgrades directly. But it's a real-world stress test for EV batteries and charging reliability, useful context if you're weighing an electric vehicle alongside home charging or solar plans. The van tested here, the ID. Buzz Pro Long Wheelbase, uses an 86 kWh battery and can charge from 10% to 80% in under 30 minutes on a fast charger.
Podcast: Tesla Roadster gets a date, VW XL1 comes back electric, BYD’s new Tesla fighter, and more
This is a podcast episode about cars and EVs, not home energy upgrades, so there isn't much here that touches your own house directly. The episode covers Tesla's new Roadster reveal set for October 1, a redesigned Supercharger design meant to speed up charging station buildout, and safety data on Tesla's driver-assist crashes. It also touches on new electric vehicle models from Volkswagen, BYD, Hyundai, and Kia, along with a note on Chinese automaker BYD undercutting Tesla's Model 3 price and a warning from Hyundai that cheaper Chinese EVs could soon reach the US market. None of this involves home weatherization, heat pumps, rebates, or other house-focused upgrades. If you're weighing an EV purchase alongside home energy work, the main thing worth knowing is that vehicle prices in the EV market keep shifting, with more competition and lower price points showing up from multiple manufacturers. But there is no news here about home electrical upgrades, charging equipment for your house, or rebate programs tied to EV ownership. For homeowners tracking energy-efficiency programs, this piece has nothing new to report. It's aimed at readers following the broader EV and green-transportation industry, not at anyone deciding on insulation, heating systems, or home electrical work.
Anker SOLIX E10 system sale starts from exclusive $3,799 low, Heybike ALPHA mid-drive e-bike $1,099 low, EcoFlow, more
This week's deals roundup includes a few items worth a look if you're weighing home energy or battery backup upgrades. Anker's SOLIX E10 whole-home backup system, a battery setup meant to keep your house running during an outage, is on sale with exclusive bonus savings starting at $3,799. EcoFlow also has a flash sale on its DELTA 3 Ultra Plus power station, a 3,072Wh battery that can pair with solar panels to charge, bundled with a 500W modular solar panel for $1,899. For those looking at electric yard equipment, EGO's Multi-Head System with an 8-inch carbon-fiber edger attachment has dropped to a new low of $173. Roborock is also offering its RockMow X115H and X130H robot mowers at all-time lows starting at $1,500. Other smaller discounts include a Greenworks 24V 4.0Ah battery two-pack and Meross's two-zone smart water timer, which can help manage irrigation more efficiently. Outside the home energy space, there's an exclusive $700 discount on Heybike's ALPHA all-terrain mid-drive e-bike, bringing it to $1,099, plus leftover deals from earlier in the week, including a Tenways e-bike sale with savings up to $807 and a bundle on the Mammotion LUBA Mini 2 AWD robot mower. As with any sale roundup, prices and availability can change quickly, so it's worth checking current listings before deciding if any of these fit your plans.
PacWave Opens—A Giant Leap for Marine Energy
A new test site for wave energy just opened off the Oregon coast, called PacWave South. It's the country's first grid-connected, open-ocean facility built specifically to test devices that turn ocean waves into electricity. Led by Oregon State University with funding from the U.S. Department of Energy, the site opened after 15 years of planning and construction. It sits about 7 miles offshore and can host up to 20 wave energy devices at once, feeding power through undersea cables to an onshore facility, with the potential to send up to 20 megawatts to the grid. The significance is mainly for the wave energy industry, not for individual homeowners right now. PacWave lets companies test their technology in real ocean conditions under a single 25-year federal permit, instead of each developer having to get its own environmental approvals. It also gives their results international accreditation, which matters for attracting investors and insurance before these devices can be sold commercially. For now, this is early-stage infrastructure development, not a technology you can put on your house or add to your utility bill. Wave energy is still years away from being a mainstream power source. If it eventually scales up, it could add more clean electricity to regional grids, including in Oregon, but there's no rebate, program, or purchase decision here that affects your home today.
Trump’s War On Wind Turbines Takes Another Ludicrous Turn
The Department of Energy has folded its wind and solar offices into a single new group, the Integrated Energy Systems Office. Inside that office, wind power now falls under a branch with a new name: "aeromechanical energy systems." The rebrand doesn't come with new money. The office lists only one open funding opportunity right now, and it's for space-based solar, not wind. Everything else tied to wind is listed as "under review," with no timeline given. This is happening against a broader effort by the Trump administration to slow wind power, especially offshore wind. A federal judge ruled last year that a president can stop issuing new offshore wind leases, which blocks most new projects since offshore leasing is federally controlled. Separately, the Department of Defense froze the routine permit-review process for wind farms with turbines over 200 feet tall, a process that also involves the FAA. Nineteen state attorneys general sued over that freeze, and a federal judge ruled in August that the freeze was illegal. None of this changes rebate programs, tax credits, or incentives for home energy upgrades. It's a story about federal wind-energy policy and bureaucratic reshuffling, not about homeowner programs like weatherization assistance or heat pump rebates. If you're weighing a home energy project, this doesn't affect what's available to you directly, though it does show that the wind side of the country's power mix is facing continued political and legal headwinds at the federal level.
ReFuelEU’s First Year Shows the Mandate Works
This one is about aviation fuel policy in Europe, not home energy upgrades, so it has little direct bearing on your house. A new report on the EU's sustainable aviation fuel (SAF) mandate found that airports supplied 1.1 million tonnes of SAF in 2025, or 2.8% of all aviation fuel, beating the required 2% target and up sharply from 0.6% the year before. The report also flagged problems. Most of that fuel came from used cooking oil and animal fats, feedstocks prone to fraud or already needed by other industries, and 85% of the raw materials were imported, mostly from China, up from 69% the year before. Meanwhile, "e-SAF," a synthetic jet fuel meant to cut emissions further, has around 60 projects in development across Europe but none have reached the stage of a final investment decision, meaning money is not yet committed to build them. The report's authors argue the EU should keep its SAF targets in place to give investors confidence, push harder to get e-SAF projects actually funded and built, and reduce reliance on imported waste oils. None of this changes rebates, equipment costs, or programs available to homeowners. It is a policy story about how Europe fuels airplanes, worth knowing if you follow climate and energy news broadly, but it does not affect decisions about insulation, heat pumps, or other upgrades to your own house.
XPeng shops its self-driving tech to automakers — Tesla found no takers
This story is about self-driving car software, not home energy upgrades, but there's a small note worth passing on if you drive an electric car or are thinking about one. The main news: Chinese EV maker XPeng is trying to sell its self-driving and smart-cockpit technology to other automakers, following a deal it already has with Volkswagen. Tesla has been trying to do the same thing with its "Full Self-Driving" (FSD) system for years and hasn't landed a single outside customer, reportedly because other automakers don't want to take on liability if the system fails. The technical difference: XPeng's cars drive mainly on cameras, like Tesla's, but XPeng kept radar and other sensors as a backup safety system running separately from the main driving software. Tesla removed those extra sensors, relying on cameras alone. That backup layer is one reason other companies find XPeng's system easier to trust and insure. None of this changes any rebate, tax credit, or program that affects your house. It's simply a look at how the self-driving car market is shaping up. If you drive or plan to drive an EV, the article's writer notes that charging it from home solar panels can cut your fuel costs, since electricity rates have been rising, but that's a general aside and not tied to this specific piece of car-technology news.
The hidden power systems behind AI
This is a podcast episode about the electrical systems inside AI data centers, not something with a direct action for homeowners. Still, it points to a trend worth knowing about: the huge computing centers that power AI are changing how they use electricity and batteries, and that has ripple effects on the broader grid. Data centers used to keep batteries around for one reason, to keep servers running for a few moments until backup generators started. Now those batteries do more. They smooth out spikes in electricity demand, work with power generated onsite, and act as a buffer for the local grid. The discussion also touches on a shift from standard AC (alternating current) wiring to higher-voltage DC (direct current) systems inside these facilities, a change in how power moves from the source to the computer chips. None of this changes anything about rebates, upgrades, or costs for your own house right now. But data centers are becoming major users of electricity and batteries, and the choices they make about grid support and backup power can affect how utilities plan capacity and pricing in the areas where these facilities operate. It is a sign of how much energy infrastructure is being reshaped by AI's power demands, even if the direct link to a homeowner's electric bill or upgrade plans isn't spelled out here.
BYD Planning 4 Factories in Europe
Chinese automaker BYD is planning to build out a bigger footprint in Europe: three vehicle assembly plants and one battery factory. Production has already started at its first European plant in Hungary, and the company expects to decide on a second manufacturing site by the end of the year. Spain and France are among the preferred locations, and BYD is looking to buy and refurbish an existing factory rather than build new. The move is largely a response to high EU tariffs on electric vehicles made in China, which push BYD to manufacture inside Europe if it wants to compete there. Europe is a huge market for new-car sales, but electric vehicles still don't make up the majority of sales in most countries, so BYD sees room to grow. For homeowners, this doesn't change anything about home energy upgrades or rebates. It's a sign that more electric vehicle manufacturing and competition may be coming to Europe over the next few years, which could eventually affect EV prices and availability there. It has no direct bearing on U.S. weatherization programs, heat pump incentives, or other home efficiency rebates covered here.

Waymo’s Next Target: Singapore
This news is about self-driving taxis, not home energy upgrades, so it does not affect your house or any rebate program. Waymo, the robotaxi company already running driverless cars in more than a dozen US cities, plans to launch service in Singapore in 2028. Testing vehicles will start arriving there in the coming months to map roads and gather data ahead of that launch. Singapore has strict rules for self-driving cars. Before Waymo can carry passengers, it needs approval from the city's Land Transport Authority, and its vehicles must pass a safety review run by the Centre of Excellence for Testing and Research. Waymo has already set up a local company there and joined a government committee on autonomous vehicles. The move follows Waymo's recent expansion into the UK, Germany, and plans for Japan next year, showing the company is moving beyond the US market on a fairly slow, deliberate timeline. None of this involves home electrification, weatherization, or energy rebates, so there is nothing here for you to act on around your own house. It is simply a sign of how fast robotaxi service is spreading to new countries, which may be of interest if you follow clean transportation news generally.
