EPA Proposes Air Pollution Exemption “Deal” for Data Centers in Georgia
The EPA has proposed a rule that would remove public notice and comment requirements for air pollution permits issued to "minor sources," a category that covers most data centers and the large diesel generators they use for backup power. Under current rules, these permits allow some public input. The new proposal would cut that out entirely, meaning neighbors would no longer have a formal way to learn about or challenge new generator installations near their homes. This matters most right now in Georgia, where data centers have been expanding quickly and often rely on fleets of diesel generators for backup power. The Sierra Club has spent nearly two years pushing Georgia's environmental regulators for more transparency on how many generators are running at these sites and what their combined pollution adds up to. The group argues the EPA's proposal would weaken one of the few tools residents have to push back on these facilities, since data centers are often permitted piecemeal in ways that can obscure their total air quality impact. If you live near a data center or one is being proposed in your area, this rule change could affect whether you get any advance notice or chance to comment before new generators go in. The EPA has scheduled a public hearing on the proposal for July 22, and written comments are being accepted through August 21, 2026.
Peak Energy to start 4-GWh sodium-ion ESS manufacturing facility in Sacramento
Peak Energy is building a large battery factory in Sacramento, California, to make sodium-ion energy storage systems — batteries that use sodium instead of lithium, generally at lower cost. The 183,000-square-foot facility is expected to produce enough batteries each year to store 4 gigawatt-hours of electricity, mostly for grid-scale use rather than individual homes. The company plans to start production and shipments in early 2027, backed by more than 6 gigawatt-hours in customer orders already lined up. The project involves a $71 million investment and is expected to create 239 local jobs, with support from a $10.5 million California state tax credit. The technology itself is notable for homeowners keeping an eye on battery costs and reliability. Peak says its system is designed to run for more than 20 years without scheduled maintenance and without the battery refrigeration that many current systems need. Removing that refrigeration requirement, the company says, could save California ratepayers around $100 million a year and help bring down the overall cost of energy storage. This news is about industrial-scale manufacturing, not a product you can buy for your house. But sodium-ion technology is also showing up in smaller residential batteries from other companies, and cheaper, longer-lasting grid storage can eventually help lower electricity costs and improve grid reliability in areas served by these systems, including in California.
ChargePoint, Optimus Energy plan to expand EV charging network in Southeast US
If you drive an electric vehicle in the Southeast, public charging is about to get a bit easier to find. ChargePoint and Optimus Energy Solutions, a Florida-based clean-energy company, are partnering to add 200 new charging ports across the region. ChargePoint will supply the charging hardware and software, while Optimus will own and run the stations. Many of the new chargers are planned near restaurants and shopping centers, spots people already tend to visit while their car charges. This is part of a broader push to fill gaps in public charging, which has been one of the main reasons some people hesitate to buy an EV. Other companies are making similar moves: Circle K plans 350 charging sites with the automaker-backed network Ionna, and General Motors recently launched a tool called Energy Pass that lets its EV owners pay for charging at different networks, including Tesla Superchargers, through one app. GM says it plans to add ChargePoint and EVgo to that platform soon. None of this changes anything about your home charging setup or any rebates you might use for a home charger. It mainly affects where you can plug in while out running errands or traveling through the Southeast. A recent industry satisfaction survey found that public charging availability was the most improved factor in EV owner satisfaction this year, so more stations like these could make road trips or errands in an EV a bit less stressful if you live in or travel through the area these companies are targeting.
KKR to buy EDF power solutions’ North American operations for $4.2B
The investment firm KKR is buying the North American operations of EDF power solutions, the clean energy arm of French utility EDF, for $4.2 billion, with up to $390 million more possible depending on how the deal plays out. EDF power solutions owns and operates a large portfolio of solar, wind and battery storage projects across the U.S. and Canada, serving utilities, companies and other large customers. It has developed 26 gigawatts of wind, solar and battery storage projects in North America and has 17 gigawatts under service contracts, ranking among the top 10 renewable energy owners in the country. KKR says the deal is meant to help expand this clean energy portfolio and speed up new projects at a time when electricity demand is climbing, driven by data centers, factories moving back to the U.S., and more electric equipment overall. The company is funding the purchase through its infrastructure investment arm. This is a corporate ownership change in the renewable energy industry, not a program or rebate homeowners can apply for. It does not affect home energy upgrades, tax credits, or utility rebates directly. But it is a sign that large investors see rising demand for electricity and are betting on more solar, wind and battery storage capacity being built in North America, which can shape how much power is available and how it is priced in the years ahead.
Ask a Scientist: How is Rural California Anticipating and Building Resilience to Climate Change?
This is a story about how one rural California town is adapting to climate change, not a program you can sign up for. Allensworth, a low-income farming community northwest of Los Angeles, has dealt with decades of water shortages, poor air quality, and unreliable infrastructure, made worse by extreme heat that can top 110°F. Researchers at the Union of Concerned Scientists have been working with the town on ways to shift away from water-intensive farming toward more sustainable land use. The approach centers on "nature-based solutions" — using natural systems instead of heavy infrastructure to solve problems. Examples include capturing floodwater to refill groundwater supplies, creating pesticide-free buffer zones for cleaner air and safe outdoor space, and "ecovoltaics," which pairs solar panels with restored natural habitat so land produces clean power while also supporting wildlife. Allensworth is also pursuing "agrivoltaics," growing crops and generating solar energy on the same land, as a path toward energy independence. That energy independence matters locally because an unreliable power supply currently puts drinking water access at risk during extreme heat. None of this involves a specific rebate or deadline for individual homeowners. But the ideas — pairing solar generation with land use, and building local resilience against heat and water shortages — reflect a broader shift in how communities are thinking about climate adaptation, especially in places prone to drought and extreme heat. If you live in a similarly exposed area, it may be useful context for how nearby communities are approaching energy and water resilience, even if the specific programs described here are local to Allensworth.
Global EV sales hit 2 million in June – and the US falls further behind
Global electric vehicle sales passed 2 million in June, but the picture looks very different depending on where you live. Europe had its strongest month on record, with sales up 31% from a year earlier, driven by government incentives, high gas prices, and a new wave of smaller, more affordable EVs from Renault, Volkswagen, Skoda, and Cupra. France, Denmark, Spain, and Portugal all set monthly sales records. The US is moving the opposite direction. Sales in North America are down 20% so far this year, a decline tied largely to the end of the federal EV tax credit last September. Electric vehicle sales at GM and Ford have fallen even more than the overall market as both companies rework their EV plans. If you've been waiting for prices to drop or incentives to return before considering an EV, this suggests the near-term US market has less support than it did a year ago, though local and state programs may still offer help depending on where you live. China's domestic EV sales are also down for the year, so automakers there are exporting more instead, including record shipments of electric and hybrid vehicles to Europe. In Canada, the first Chinese-built Lotus SUVs arrived in July under a new tariff arrangement that lets a limited number of Chinese EVs in at a much lower tariff than before. For US homeowners weighing an EV purchase or a home charger, the takeaway is that federal support has weakened, so it's worth checking what incentives, if any, still exist in your state.
Ameresco Brings Rooftop Solar to Community College of Philadelphia
The Community College of Philadelphia is adding rooftop solar panels to two of its campuses, the main Spring Garden Street location and the Northeast Regional Campus. Energy company Ameresco is handling the project, which is backed by Pennsylvania's Solar for Schools grant program. Construction is set to start in summer 2026 and finish by the end of the year. The project is structured as an energy performance contract, a financing arrangement where savings from lower energy use help pay for the upgrade over time. The goal is to cut the college's reliance on grid power, add resilience during outages, and support Pennsylvania's broader push for renewable energy at schools. The college also plans to use the solar arrays as a teaching tool for students. This isn't a program homeowners can apply to directly, since Solar for Schools is aimed at educational institutions. But it's a sign that Pennsylvania is actively funding solar installations through state grants, which is worth knowing if you're curious about what support exists in your area. Homeowners looking into rooftop solar for their own house would need to check what residential incentives or rebates Pennsylvania, or their own state, currently offers, since school grant programs like this one work under different rules than residential solar incentives.
DOE closes up to $3.26B loan to AEP Texas
The U.S. Department of Energy has closed a loan of up to $3.26 billion to a subsidiary of American Electric Power to upgrade and build electric transmission lines across Texas. The money will fund about 100 projects, including rebuilding or "reconductoring" (replacing wires on existing towers with higher-capacity lines) and building new lines, covering roughly 2,800 miles. DOE says the work is expected to save homes and businesses in the area about $685 million in electricity costs over the next 30 years. The upgrades aim to double the capacity of existing transmission infrastructure to handle growing power demand in Texas, driven partly by data centers, manufacturing, and oil and gas operations in the Permian Basin. AEP Texas says it has agreements in place to support up to 41 gigawatts of potential new electricity demand through 2030. If you live in AEP Texas's service area, this news is mainly about the grid you draw power from, not a program you sign up for. There is no rebate or direct action tied to this loan. It reflects a broader federal effort: AEP's Texas subsidiary is the fourth utility to get financing through the Trump administration's Energy Dominance Financing program, following loans to Southern Co. subsidiaries in Alabama and Georgia, Michigan's DTE Gas, and another AEP subsidiary covering Indiana, Michigan, Ohio, Oklahoma and West Virginia.
Toyota delays Highlander BEV production as the 3-row electric SUV is put on the back burner
Toyota is delaying production of its first three-row electric SUV, the 2027 Highlander BEV. A company spokesperson said the delay is for "additional adjustments" before launch, though no new production date has been announced. In the meantime, Toyota will keep building the current gas and hybrid Highlander through December, and those versions are expected to stay available at dealerships well into 2027. The delay applies only to the electric version. This is a car-buying story, not a home-upgrade one, but it may matter if you were considering an electric three-row SUV. The Highlander EV was expected to offer two battery options, 77 kWh or 95.8 kWh, with driving range up to 287 or 320 miles depending on the trim and drivetrain (front-wheel or all-wheel drive). Pricing was expected to start around $50,000, which would have undercut rivals like the Tesla Model Y L ($61,990), Kia EV9 ($54,900), and Hyundai IONIQ 9 ($58,955). Toyota's related three-row electric models, the Lexus TZ and Subaru Getaway, share the same platform, so it is possible they could face similar delays, though that has not been confirmed. If you are shopping for an electric SUV with third-row seating this year, your current options remain the Model Y L, EV9, and IONIQ 9, since the Highlander EV's timeline is now uncertain.
Metalcon to Put the Spotlight on the Challenges, Opportunities for Contractors
This is a trade show announcement for people who work in construction and HVAC, not a program or rebate homeowners can use directly. METALCON 2026, an industry conference for metal construction and sheet metal contractors, will be held October 7-9, 2026 in Orlando. Sessions will cover topics like reflective insulation and radiant barriers for metal buildings, updates to metal construction codes, and a broader outlook on the industry through 2027. While this isn't something homeowners attend or benefit from directly, it does touch on technology relevant to home energy efficiency. One session focuses on reflective insulation and radiant barrier systems, which can be paired with standard insulation to reduce heat transfer and moisture problems in metal buildings and roofs. These are the same kinds of materials that sometimes show up in attic and roof upgrades meant to improve a home's energy performance. The code-update session also matters indirectly, since building codes eventually shape what standards new construction and major renovations must meet. There is no rebate, deadline, or homeowner program tied to this event. It is aimed at contractors and industry professionals looking to stay current on codes, materials, and market trends. For homeowners, the practical takeaway is limited: this is background on where commercial and metal-building construction practices are headed, not a new incentive or requirement affecting your own house right now.
How to build a highway in the age of climate change
California is moving ahead with a $500 million plan to rebuild part of Highway 37, the flood-prone route linking Solano County to Marin and Sonoma. Over five years, crews would replace one bridge with a version 5 feet taller, raise two one-mile stretches by up to 8 inches, add carpool and bus lanes, and restore surrounding tidal marsh. The road, built on causeways through wetlands near San Pablo Bay, floods regularly and could be permanently underwater in parts by 2050 as sea levels rise. Some researchers and advocates argue the fix doesn't go far enough and want the highway moved miles inland, or want a $10 billion, decades-long rebuild that raises nearly the whole road and adds transit or bike lanes. Regional planners say that bigger version is the eventual goal but is too costly and slow to start now; they've secured $270 million for a bridge replacement as a first step. This isn't just a California problem. Coastal roads and causeways from Florida's Sanibel Island to Georgia's Tybee Island face similar flooding and closures as seas rise and storms intensify. Some places are testing nature-based fixes like oyster reefs, rain gardens, and living shorelines to absorb wave energy instead of relying only on raising pavement or building seawalls. Researchers also note that rising groundwater can weaken roads from below, shortening their lifespan even without a storm. For homeowners, the takeaway is less about your own house and more about the roads you depend on. If you live near a coast, a marsh, or a low-lying causeway, expect more debate in your area over how much to spend, and how, to keep those roads passable as flooding becomes routine.
Western Europe just set the record for its hottest June ever
Western Europe just had its hottest June on record, averaging 20.74 degrees Celsius (about 69 degrees Fahrenheit) across the whole month, day and night, according to the EU's Copernicus Earth observation program. That edges out the previous record set in June 2025 and runs more than 3 degrees Celsius above the usual average for the month. Ocean temperatures hit record highs too, and globally, June came within a hair of the all-time heat record. The heatwave behind these numbers closed schools, disrupted power supplies, and has been linked to thousands of deaths across the continent. France, Germany, and Denmark each recorded their highest temperatures ever. Scientists with the World Weather Attribution initiative say heat like this would have been almost impossible 50 years ago, and that climate change has made daytime heat extremes 10 times more likely and overnight heat extremes 100 times more likely compared with Europe's hot summer of 2003. High nighttime temperatures are especially hard on health because bodies don't get a chance to cool down and recover before the next hot day. None of this is specific to any one house, but it points to a broader trend: homes built for milder, cooler climates are increasingly facing conditions they weren't designed for. Experts quoted in the coverage point to steps like reflective roofing, cooler wall materials, and wider access to air conditioning as ways homes and cities could better handle this kind of heat going forward.
Why data centers powered by off-grid gas flunk a new climate investor test
A new scoring tool aims to help investors judge whether money going into data centers actually speeds up the shift away from fossil fuels. Built by the Rhodium Group with the California pension fund CalSTRS and clean energy investor Generate Capital, the framework grades data center power setups by how much climate impact they deliver for the capital spent. Data centers were picked as the first test case because they are drawing huge amounts of investment right now, and some big funds want to know if that money is helping or just business as usual. The highest scores went to data centers connected to the regular power grid but backed by contracts for new nuclear or enhanced geothermal power, technologies that are still expensive and hard to finance on their own. Grid-connected centers running on 100% renewable power contracts also scored well, followed by off-grid facilities that rely mainly on renewables and batteries with gas only as backup. Setups built around standalone gas turbines, or gas-heavy power mixes meant to bridge years until a grid connection is ready, scored poorly. A standard grid hookup with no special clean power deal was ranked neutral. None of this changes anything for homeowners directly. It is a tool for large investors deciding where to put money into the data centers powering things like cloud computing and AI. But it points to how the industry is choosing between gas, renewables, nuclear, and geothermal to power its rapid growth, at a time when the energy use of data centers keeps climbing.
Bill Frist Wants To Bridge The Partisan Divide Over Climate Change
Bill Frist, a former Senate majority leader from Tennessee and a heart transplant surgeon, has become one of the few prominent Republicans speaking out on climate change. He argues that a healthier planet means healthier people, pointing to research linking air pollution and rising temperatures to higher rates of cognitive decline, heart and lung disease, and health care costs. His shift is notable because his Senate environmental record was weak, including a vote to allow oil drilling in the Arctic National Wildlife Refuge, a position he now says he would not repeat. Frist is framing climate action around health rather than politics, hoping to reach people across party lines by focusing on the wellbeing of families and children now, not decades in the future. He points to studies showing habitat loss and pollution affect children's immune systems and brain development, and has testified to Congress about climate-driven health costs. He is part of a small group of conservatives, sometimes called the "eco-right," who expect Republican climate policy to shift eventually as the effects of a warming climate become harder to ignore. This story is about a shift in political messaging, not a new program or rebate. It does not include any new incentives, deadlines, or technologies for homeowners to act on. It is worth knowing about mainly as a sign that climate and health arguments may be gaining traction across the political spectrum, which could shape future energy and climate policy.
Bosch’s Real Hydrogen Mistake Was Strategic, Not Financial
This is a story about auto industry strategy, not a home upgrade program, but it's a useful sign of where things stand with hydrogen versus other technologies. Bosch, the giant German auto parts maker, spent close to €2.5 billion on hydrogen technology between 2021 and 2026, betting heavily on hydrogen fuel cells for trucks and vehicles. The company can easily absorb that cost. But the bigger problem was strategic: while Bosch poured engineering time and attention into hydrogen, the real shift in car technology was moving toward batteries, electric motors, and software, not fuel cells. For homeowners, this matters mainly as a broader signal. Hydrogen has struggled to become a mainstream option for everyday transportation, largely because it still needs fueling stations, cheap low-carbon hydrogen, and heavy government support to work at scale. Battery-electric technology, meanwhile, keeps gaining ground faster, including in China, where electric trucks and buses are advancing quickly. That pattern mirrors what's happening in home heating and appliances too: electric options like heat pumps continue to pull ahead of hydrogen-based alternatives in cost and practicality. None of this changes any rebate program or deadline for your house. But it is a reminder that the technologies gaining real traction, and the ones utilities and manufacturers are investing behind, are electric ones. If you are weighing an upgrade, the direction of travel across the wider energy and transportation world keeps pointing the same way: toward electrification, not hydrogen.
Fluke introduces portable hoisting tool to mitigate ladder installation risks
Fluke has launched a new tool called the PV Module Lift, designed to make it safer to carry solar panels up a ladder during rooftop installation. It's a manual, unpowered hoisting kit that attaches to standard extension ladders and uses a pulley system to raise panels while workers keep both hands free to hold onto the ladder, which is a safety requirement (three points of contact) under federal workplace rules. The whole system weighs 33 pounds and fits in a canvas bag, so it avoids the fuel, setup time, and bulk of powered ladder hoists. It works with common Werner or Louisville fiberglass extension ladders already used on job sites. A hook holds the panel in place so it doesn't slide sideways, built-in ramps let the panel glide smoothly over the spot where ladder sections overlap, and a braking mechanism automatically locks the panel in place if the rope is let go by accident, so it can't fall. One person can unpack and set up the whole system in under five minutes. It comes in two versions, with either a 60-foot or 80-foot rope, depending on how high the crew needs to reach. This is a safety and equipment upgrade aimed at solar installation crews rather than something homeowners need to buy or choose. But if you're planning a rooftop solar installation, it's part of a broader trend of companies building better tools to make panel installation safer and more efficient on site.
What’s your space strategy? Why organizations must determine what matters before markets do
This piece is aimed at corporate strategy teams, not homeowners. It argues that companies now have to decide whether to invest in emerging technologies, like space infrastructure, before those markets have proven themselves. Historically, businesses waited for a technology to show clear results before committing money or attention. The author says that pattern has flipped: by the time proof arrives, early movers have already shaped partnerships, standards, and funding, so waiting is not really a safe or neutral choice anymore. The article uses sustainability examples to make this point. Renewable energy, electric vehicles, sustainable aviation fuel, and carbon removal all drew corporate interest long before their paths to large-scale use were clear. The people and companies who engaged early helped create the conditions that let those markets grow, rather than simply reacting once the technology was proven. There is nothing here about specific home upgrades, rebates, appliances, or costs. It is a discussion of corporate decision-making and how businesses approach new and uncertain technologies, including space ventures. It does not mention any programs, dollar amounts, deadlines, or eligibility rules that would affect a homeowner's energy upgrade plans, so there is no direct action or takeaway for your own house in this one.
EcoFlow 3,072Wh DELTA 3 Ultra power station $1,299 in Outdoor Season Sale, Velotric Discover 2 e-bike $1,799, more
This roundup covers gear deals rather than energy-efficiency programs, but a few items relate to home power and EV charging. EcoFlow's Outdoor Season Sale cuts prices on its portable power stations, with discounts up to 57% starting at $259. The standout is the DELTA 3 Ultra, a 3,072Wh power station (a battery that can run appliances or back up power during an outage), now $1,299. For electric vehicle owners, Schumacher has a NACS to J1772 charging adapter down to a new low of $47.50. This lets EV drivers use charging plugs that don't match their car's native connector, which can matter if your home charger or a public station uses a different plug standard than your vehicle. Other deals include the Velotric Discover 2, a step-through commuter e-bike with a 75-mile range, Apple Find My tracking, and swappable sensor tech, priced at $1,799 as part of a separate sale. There's also a Worx 40V cordless electric lawn mower, sold with two batteries, for $230. None of these are tied to rebates or efficiency programs — they're retail discounts on outdoor power and EV-related equipment. If you're already looking at backup power for your home, an EV charging adapter, or an electric mower, these prices may be worth a look, but they don't connect to any incentive program or deadline.
Inside the AI power wars
Big tech companies are racing to secure enough electricity to run their AI data centers, and the power grid can't keep up. Utilities that once promised companies a gigawatt of power by 2027 are now pushing those dates back years, so Google, Amazon, Microsoft, Meta, and AI developers like OpenAI and Anthropic are increasingly building their own power sources rather than waiting on the grid. This includes gas turbines, large engines, solar and battery setups, and fuel cells installed directly at data center sites, an approach known as "behind the meter" power. Google has emerged as the most experienced player, using its financial strength to back Anthropic's data center buildouts in exchange for Anthropic buying Google's computer chips. For homeowners, the direct link is limited, but the trend matters because these companies are competing for the same electricity supply chain that serves houses and neighborhoods. As data centers absorb more gas turbines, generators, and grid capacity, and as utilities negotiate huge new contracts with tech companies, the added demand could affect how fast utilities invest in the local grid and how electricity costs are shared across all customers, including residential ones. None of this changes what rebates or incentives are available for home upgrades like heat pumps or insulation, but it is part of the backdrop explaining why the power grid feels increasingly strained in areas with heavy data center construction, and why some utilities are more focused on serving big commercial customers than on residential grid upgrades.
Avangrid Begins Panel Installation at Oregon Trail Solar, Supports Local Jobs
Avangrid has started installing solar panels at Oregon Trail Solar, a large project in Gilliam County, Oregon. The project will produce 57 megawatts DC (41 megawatts AC) of power and is on track to finish next year. Once complete, it will include more than 100,000 solar panels and generate enough electricity to power about 10,000 U.S. homes each year. Construction is supporting 200 local union jobs. This is a utility-scale solar farm, not a residential program, so it does not offer a rebate or incentive homeowners can apply for directly. Its effect on your household would come through the grid: more solar generation feeding into Oregon's electricity supply as demand grows. Avangrid says the project will also contribute $6 million over its lifetime in combined payments in lieu of taxes and property taxes to Gilliam County, money meant to support local schools and infrastructure. Oregon Trail sits next to Avangrid's existing Pachwáywit Fields solar project and a battery storage project the company recently announced nearby. Avangrid already operates more than 2.5 gigawatts of energy capacity in Oregon, along with a training center in Sherman County and a corporate office in Portland. For homeowners, the news mainly signals that more solar capacity is coming online in the region, which can factor into the broader picture of where your electricity comes from, though it does not change what upgrades or rebates are available for your own home.
New bill would ban Tesla’s camera-only Robotaxi, not Waymo
New Jersey lawmakers are moving forward with a bill that would set hardware rules for driverless commercial vehicles, and it happens to rule out Tesla's current approach. The bill would require fully driverless vehicles to use cameras plus two other types of sensors, in practice meaning radar and lidar in addition to cameras. Tesla's Robotaxi relies on cameras alone, so it wouldn't qualify. The bill also favors vehicles that keep a steering wheel and pedals, which would rule out Tesla's Cybercab, a vehicle already in production without either. Neighboring New York is weighing a similar rule. This is not about consumer cars. The bill's sponsor has clarified it only applies to companies running driverless commercial fleets, not to features like Autopilot or Full Self-Driving in personal vehicles, which still require a licensed driver paying attention behind the wheel. Tesla had urged its New Jersey owners to contact lawmakers, warning the bill would ban Tesla from the state, and thousands of owners emailed in protest, some worried their own cars' driver-assist features would be disabled. That fear turned out to be off base. If you own a Tesla with Autopilot or Full Self-Driving, this news doesn't change how your car works today. It matters mainly if you're watching whether robotaxi services expand into New Jersey, since companies like Waymo, which already use cameras, radar, and lidar together, would meet the proposed rules, while Tesla's driverless plans would not unless it adds more sensors.
MG is launching its first PHEV with semi-solid-state batteries in 2027
This is car news, not a home energy story, but here's what's happening. Automaker MG plans to sell its first plug-in hybrid (PHEV, a car with both a gas engine and a rechargeable battery) using "semi-solid-state" batteries, starting with the MG ZS Plug-in Hybrid+ in 2027. Two more SUVs, the MG HS and MG S9, will follow with the same battery tech. Semi-solid-state batteries use a different internal design than the standard liquid-electrolyte batteries in most electric and hybrid cars today. MG says the new batteries charge faster, respond to power demands more quickly, and hold up better in extreme temperatures than conventional batteries. Paired with a new hybrid drive system, MG claims the cars can run in full electric mode more efficiently and keep the gas engine running at a high thermal efficiency most of the time. MG also plans a highway driver-assist feature called Navigate On Autopilot for late 2027. None of this involves your house directly. It's about upcoming vehicles, not home batteries, solar storage, or anything tied to weatherization or rebate programs. But battery technology like this sometimes trickles into other products over time, including home energy storage, so it's worth knowing as background if you're the kind of homeowner tracking where battery tech is headed. For now, there's nothing here that changes any decision about your own home.
Walmart Supporting … Nuclear Power?
Walmart has signed a deal to buy nuclear power from an existing plant, Constellation's Dresden Clean Energy Center in Illinois. This isn't a new reactor being built. Instead, Walmart is paying for output from upgrades to the existing plant, called "uprates," that let it generate more electricity without new construction. The deal covers about 176 megawatts of power, including 30 megawatts of new capacity from those upgrades, and runs through two 15-year terms starting in 2029 and 2030. This is the first nuclear power purchase agreement of its kind for Walmart, and one of the first between a large retailer and a nuclear plant in the country. The power will help run a new high-tech distribution center Walmart is building in Belvidere, Illinois, and is meant to give the company steady, carbon-free electricity while supporting the local grid and jobs in the region. For homeowners, this doesn't change anything directly about your house, your utility bill, or any rebate programs. It's a corporate energy deal, not a policy change or a new incentive. But it's a sign of where big companies are looking for reliable, low-carbon power as electricity demand grows, and it shows that upgrading existing nuclear plants, rather than building new ones, is seen as a cheaper way to add clean capacity to the grid.
China’s giant Gobi solar plant runs after dark on salt, not batteries
China has switched on the world's largest solar plant to combine ordinary panels with concentrated solar power, a setup that stores heat instead of electricity. The Hami complex in the Gobi Desert pairs 900 megawatts of standard solar panels with a 100-megawatt unit that uses mirrors to heat molten salt to over 1,000°F. That stored heat can run a turbine for up to eight hours after sunset, so part of the plant keeps producing power well into the evening without any batteries. It's worth noting that the after-dark output comes from the 100-megawatt thermal section, not the full gigawatt of panels. The project cost about $480 million to build and, at full capacity, is projected to generate enough electricity yearly for roughly 830,000 households while cutting significant carbon emissions. China plans to expand this site and is already building a second, larger hybrid plant nearby using the same idea. None of this changes what's available to homeowners today. This is a utility-scale demonstration project, not a home technology, and the story itself flags a real open question: molten-salt storage has historically cost more per unit of power than pairing solar panels with lithium batteries, and battery prices keep falling. So this is a technology to watch rather than something that affects rooftop solar or battery choices for your own house right now.
Rivian (RIVN) — Rough Week Selling Stock For Cash? Or Booming Stock Provides Easy Opportunity For Cheap Cash?
This is company financial news about Rivian, the electric vehicle maker, and doesn't involve home energy upgrades, rebates, or weatherization programs. It's not something that affects your house or any efficiency project you might be planning. For context, Rivian sold 75 million shares of its stock to raise roughly $1.5 to $1.7 billion in cash. The money is meant for general business needs, including funding tied to a Department of Energy loan supporting the company's vehicle manufacturing plant in Georgia. The stock price dropped after the announcement, though it had jumped 17 percent just before that on strong sales news. Rivian also reported better-than-expected vehicle production and deliveries for the second quarter, and raised its sales forecast for the year. At the same time, the company pushed back its profitability target, citing higher spending on self-driving technology and new vehicle development, and it's dealing with a shortage of computer memory chips that's affecting manufacturers industry-wide. None of this touches rebates, incentive programs, or home electric vehicle charging costs. If you're weighing an EV purchase for reasons connected to home energy use, such as pairing a vehicle with solar or a heat pump setup, this is simply a look at how one automaker is financing its growth, not a change to any incentive or program you could use.
Trek targets the fat tire e-bike boom with its new throttle-enabled Borrego+
This one's outside the scope of home energy upgrades, but here's the gist for anyone curious: Trek has launched a new fat tire electric bike called the Borrego+, aimed at the popular throttle-equipped e-bike market that's mostly been dominated by smaller direct-to-consumer brands. It's a departure for Trek, which has mostly sold pricier bikes without throttles. The standard Borrego+ is a Class 2 e-bike, meaning it tops out at 20 mph and has both pedal assist and a thumb throttle. A faster version, the Borrego+ S, reaches 28 mph as a Class 3 e-bike, though Trek won't sell that version in California because of state rules on e-bike speed classes. Both use a 750W motor and a removable battery rated for up to 60 miles of range, and ride on wide, 4-inch tires meant for loose terrain like sand or gravel. The bike comes with practical extras: a suspension fork for smoother rides, a heavy-duty rear rack rated to carry 440 pounds, fenders, turn signals, and a companion app that offers a digital lock and battery alerts. The Borrego+ costs $2,499 and becomes available July 16 through Trek dealers and the company's website. It's aimed at buyers who want a well-known bike brand and nationwide repair support, but at a lower price than Trek's typical lineup.
The tiny cell that broke a big rule of biology
This one falls outside what Retrofit Relay covers. It's a story about ocean science, not home energy upgrades, so there's nothing here about heat pumps, insulation, rebates, or your utility bills. For context, though: scientists Jon Zehr and Kyoko Hagino spent decades separately chasing the same mystery. Zehr found genetic traces of a nitrogen-fixing bacteria in seawater but could never find the actual organism under a microscope. Hagino, studying ocean algae fossils, kept noticing a strange dot inside a species called Braarudosphaera bigelowii that no textbook explained. When the two researchers connected, they realized Hagino's algae was hiding Zehr's missing bacteria inside it. Working together, their teams showed the bacteria had merged so completely with the algae that it now functions like an organelle, a built-in structure inside the cell, similar to the way mitochondria and chloroplasts work in other life forms. They named it the "nitroplast." This matters because, until now, only simple bacteria and similar microbes were thought capable of pulling nitrogen from the air, a trick that plants, animals, and fungi cannot do on their own. Researchers say this discovery might eventually inform work on crops that fertilize themselves, though they caution that outcome is still far off. Interesting science, but nothing for homeowners to act on today.
BYD launches the Dolphin G plug-in hatch with 65 miles of EV range for $32,000
This one's outside the home energy space, but here's the gist: BYD has launched a new plug-in hybrid hatchback, the Dolphin G DM-i, in Europe and the UK, with US pricing not part of this launch. It's a small car that runs on electricity for daily driving but has a backup gas engine for longer trips. The higher-range version has an 18.3 kWh battery giving about 65 miles of electric-only range, plus a combined range of 646 miles once you count the gas engine. A base version with a smaller battery gets about 25 miles of electric range. Charging the bigger battery from 10% to 80% takes about 26 minutes on a fast charger, or a few hours on a home-style charger. In Germany, pricing after government and manufacturer incentives starts around $21,900, rising to roughly $33,400 without those discounts. In the UK, prices start near $32,100 and climb to about $40,200 for the top trim. None of this applies directly to a US driveway right now, since the car isn't being sold in the US. If you're weighing a plug-in hybrid for your own household, the practical takeaway is the range split: a car like this can run on battery power alone for a normal commute, then switch to gas for road trips, without needing a full public charging network. That's the same logic behind plug-in hybrids already sold in the US, even though this specific BYD model isn't one of them yet.
Forget the Fiat Golf Cart, VinFast City Car Costs $7,150 and Has Twice the Range!
Vietnamese automaker VinFast has unveiled a tiny electric city car, the VF2, priced at about $7,150. It's a small, two-door, four-seat car meant to compete with motorcycles in crowded urban markets, offering a safer, more comfortable alternative for short city trips. It's basic by design: air conditioning, a 7-inch digital instrument display, four-way adjustable driver's seat, two speakers, FM radio, and a single driver's airbag, with no other modern extras. The VF2 has a top speed of 50 mph, so it's not built for highway driving. It gets about 130 miles of range on a full charge and can charge from 10 to 70 percent in 34 minutes, which counts as reasonably quick for a car this small and cheap. This car isn't expected to be sold in the United States, so it has no direct bearing on home energy upgrades or rebates. It's worth noting mainly as a sign of how far bare-bones electric vehicles have come in price and range in other parts of the world, and a point of comparison for anyone tracking the low end of the EV market, including small commuter cars that might eventually influence home charging needs if similar models ever arrive stateside.
Xiaomi says Sky Nomad is a series, not a new brand, teases SUV
This is car news, not a home energy story, but it touches home charging math if you follow EVs. Xiaomi has clarified that Sky Nomad, its rugged new SUV, is a new vehicle series under the Xiaomi EV brand rather than a separate spinoff brand as earlier rumors suggested. The SUV, expected to launch as the N90, is Xiaomi's first vehicle that isn't a pure electric car. It uses a large battery pack of more than 70 kWh, giving 400 to 500 km (about 249 to 311 miles) of electric-only range, plus a small gas engine that acts only as a generator to extend total range past 1,500 km. That battery is bigger than the one in the base Tesla Model Y sold in China. Pricing is expected to start around 200,000 yuan, roughly $29,400. None of this changes any home energy programs or rebates. But if you're weighing an EV purchase alongside home upgrades, it's a reminder that the cheapest miles usually come from electricity generated at your own house. With grid electricity rates rising, home solar can lock in lower charging costs over time, and some installers offer lease or power-purchase options with no upfront cost. If you're shopping for panels, comparing quotes from multiple vetted installers is the easiest way to find a fair price.
BYD reveals prices for its new 1,500hp+ luxury EV sports car start at nearly $200K [Images]
BYD has priced its new electric supercar, the Denza Z, with UK starting prices of £142,900 ($192,000) for the Coupe, £159,900 ($215,000) for the Spider, and £172,900 ($232,000) for the Racing version. The car has three motors putting out a combined 1,582 horsepower, can go from 0 to 62 mph in as little as 1.96 seconds, and tops out at 217 mph. It runs on an 800-volt electrical system that lets it recharge from 10 to 70 percent battery in about five minutes. Range on the WLTP test cycle runs from 236 to 254 miles depending on the version. Sales start in late summer, with deliveries expected by the end of 2026. This has nothing to do with home energy upgrades. It is a luxury sports car aimed at buyers cross-shopping the Porsche 911 Turbo S, not a vehicle tied to any rebate or weatherization program that would affect your house. The one loosely relevant point: it's another sign that electric vehicles now cover every price and performance tier, from budget commuter cars to six-figure supercars, which may matter if you're weighing an EV purchase alongside home charging or solar plans. But nothing here changes what's available for insulation, heat pumps, or other efficiency work on your home.
Waymo Hits Summer Break With Coast-to-Coast Expansion
This is about robotaxis, not home energy upgrades, so it has no direct bearing on planning a retrofit or finding rebates for your house. Still, here's what happened: Waymo, the self-driving car company, is expanding its driverless taxi service to four new cities — San Diego, Las Vegas, Tampa, and Denver. Service will start with Waymo employees riding first, with public access expected to follow soon. Once open to the public, riders in these cities will be able to download the Waymo app and hail a car with no driver, joining more than 10 other cities where that's already possible. Separately, Waymo also said it has begun testing a new vehicle in its fleet, the Hyundai IONIQ 5, though for now these are driven with a human specialist on board while the company checks that the technology works before letting them run fully driverless. None of this touches home heating, cooling, insulation, or rebate programs, so it isn't something that changes any plans for upgrading your house. If you live in or travel to one of the newly listed cities, the practical takeaway is limited to transportation options, not anything tied to energy efficiency at home.
XPENG MONA L03: The Best Base Tesla Model Y Competitor?
This is a car story, not a home energy upgrade story, but here's what it covers. XPENG has opened presale on a new electric SUV called the MONA L03, positioned as a rival to Tesla's base Model Y. Rather than trying to out-size or out-power the Model Y, the L03 is slightly smaller and a bit less powerful, but matches or edges out the Tesla in other ways: a tighter turning radius, adaptive suspension dampers on every trim, faster charging (10-80% in 18 minutes versus 25 for the Model Y), and a quieter cabin. It also offers extra storage features, heated and ventilated massaging front seats, and tighter panel gaps in its body construction. The biggest difference is price. In China, the L03 starts around $21,000 to $24,400 depending on trim and battery range, compared to roughly $48,200 for a comparably equipped base Model Y there. XPENG is also offering a plug-in hybrid version with gasoline range extension for drivers not ready to go fully electric. The car will launch in 64 markets with strong safety ratings, though the US is not among them. None of this affects home energy upgrades or rebates directly. If you're weighing a switch to an electric vehicle as part of broader home electrification plans, this is a sign that lower-cost EV options are expanding globally, even though this particular model won't be sold in the United States.
Is Tesla In A Lose-Lose Situation With Autonomous Driving?
This piece is about self-driving cars, not home energy upgrades, so there is nothing here that touches your house directly. Still, in brief: a reader comment argues Tesla faces a bind with its self-driving software. Tesla's approach uses cameras and modest computing hardware rather than the pricier sensor packages (like radar and lidar) other companies use. The argument goes that if Tesla proves cameras alone can achieve full self-driving, other automakers already have cars on the road with even better hardware, and they could copy the approach within a year or two, wiping out any advantage. If Tesla's approach turns out not to work well enough, it falls behind rivals using more sensors, and would have to rework its entire system from scratch, while competitors would not need to. The comment section debates whether this holds up, with some owners reporting near-misses with Tesla's system and others defending it, alongside back-and-forth about whether camera-only driving can handle rain, fog, or glare, and how fast rival systems from companies like Nvidia, Mobileye, or Chinese automakers might catch up. None of this changes anything about home electrification, insulation, heat pumps, or rebate programs. It is simply industry chatter about the competitive future of robotaxis and driver-assist software, not something that affects decisions homeowners make about their own houses.
McDonald’s reassigns its chief sustainability officer to beef strategy
This is corporate news about McDonald's, not something that touches home energy upgrades directly, but here's what happened. McDonald's has moved its chief sustainability officer, Beth Hart, into a new role overseeing global beef sourcing and supply chain quality control. Hart had held the sustainability post for about two years. Her old job goes to Suheily Natal Davis, a McDonald's attorney who has worked on diversity and inclusion programs, with a new title covering sustainability, social impact and inclusion. The reshuffle comes as McDonald's reviews its climate targets. The company recently said it will miss its goal of cutting supply chain and franchise emissions in half by 2030, pointing to factors it says are outside its control. It plans to spend $1 billion over the next decade on supply chain resilience, including regenerative agriculture and grazing programs meant to make beef and other farming practices less emissions-intensive. In her new role, Hart will help decide how some of that money gets spent. Beef, along with commodities like soy, palm oil, coffee, and packaging fiber, makes up the largest share of McDonald's carbon footprint under supply-chain emissions accounting. The company says it has cut those emissions by 3 percent since 2018. For homeowners tracking energy and climate news, this is mainly a corporate governance story about how a major food company is restructuring its sustainability leadership and adjusting its climate goals. It has no direct bearing on home energy upgrades or rebate programs.
Southern California clean-heat rule survives key legal challenge
A federal appeals court has upheld a Southern California air quality rule that targets pollution from gas-fueled boilers, water heaters, and similar equipment. The U.S. Ninth Circuit Court of Appeals rejected a legal challenge from gas-appliance makers and contractor groups, keeping in place a regulation that took effect in January. The rule, set by the South Coast Air Quality Management District, gradually cuts smog-forming nitrogen oxide emissions from more than 1 million gas appliances across Los Angeles, Orange, Riverside, and San Bernardino counties. It does not ban gas equipment outright, but it does require aging or worn-out units to be replaced with zero-emission alternatives, with the rules eventually covering more types of equipment in existing buildings by 2033. For homeowners, the immediate impact is on residential pool heaters and tankless water heaters, which fall under the new emissions limits. If you own one of these in the covered Southern California counties, replacement rules will eventually apply as the equipment reaches a certain age or the end of its useful life. The policy's backers hope it will also push manufacturers to ramp up production of heat pumps and other electric alternatives, which could lower prices for these appliances more broadly, even outside California. The fight isn't fully over. Opponents, led by appliance maker Rinnai America, can still ask the court to reconsider its ruling. Meanwhile, regulators are drafting a separate set of rules for larger commercial and industrial systems, expected to go before the air district's board by the end of the year.
IRA clean energy gains mostly on track despite OBBBA, says MIT study
A new MIT study looks at how much clean electricity the country will actually get after Congress passed the One Big Beautiful Bill Act, which sped up the phaseout of tax credits from the earlier Inflation Reduction Act. The finding: most of the growth in clean power is still likely to happen. Researchers estimate about 74% of the new clean electricity capacity expected under the old law will still get built, including 82% of utility-scale solar. Battery storage holds up well too, keeping its tax credit access and reaching about 83% of what was originally expected. Onshore wind takes the biggest hit, with only about half the capacity now expected, since it depends most heavily on those credits. For homeowners, this is background context rather than a direct change to any program you'd apply to. It doesn't affect home upgrade incentives like weatherization (sealing up drafts and insulating) or heat pump rebates. It does suggest that the broader shift toward solar and battery power on the grid will keep moving forward, even if slower than planned, while new wind farms may lag. The study also notes that even under the original law, limits on permitting and transmission lines (the wires that move power long distances) meant projects could not have moved as fast as planned anyway. The report's author says restoring the lost wind and solar credits would only speed things up modestly, since the bigger bottleneck is how quickly projects can get approved and connected to the grid.
Rising Costs Force Contractors to Take a Harder Look at Pricing
HVAC contractors are rethinking how they set prices as costs for labor, materials, transportation, and tariffs keep shifting. Rather than raising prices on a fixed schedule, many are now pricing job by job, since equipment and material costs can change from one quote to the next. Industry sources say even small increases in everyday supplies add up quickly, and rising labor costs are also pushing quotes higher. For homeowners, this means a quote you get today may not match one from a few months ago, even for similar work, and prices could vary more than they used to based on when a job is scheduled and what parts it requires. Some contractors say they're trying to hold prices steady for customers as long as possible before passing on cost increases, and several say they prefer to build higher costs into the quoted price rather than tack on separate fuel or credit card surcharges, since customers tend to find those add-ons irritating even when they understand costs are rising generally. The bigger theme is that contractors are being told to track their profit margins closely and adjust prices based on real numbers, not just react every time a supplier announcement or news headline suggests costs are climbing. For someone planning a heating or cooling upgrade, this suggests it's worth asking for pricing to be clearly explained and locked in for a defined period, since costs behind the quote can move even when the underlying equipment doesn't.
Can HVAC Train Enough Technicians for the Data Center Boom?
The rapid buildout of data centers to support AI is creating a surge in demand for HVAC technicians who can install and maintain the specialized cooling systems these facilities need. A recent survey of young adults found HVAC technician ranked as one of the jobs least likely to be replaced by AI, and nearly half said skilled trades feel safer than white-collar work in an AI future. That shift, along with big investments from tech companies like Google and Meta, is drawing more young people toward trade careers instead of four-year college degrees. Industry trainers warn this demand may outpace the supply of qualified technicians. Data center cooling work is more specialized than typical commercial HVAC jobs, requiring knowledge of hydronics (water-based heating and cooling systems), fluid dynamics, cooling towers, and building automation, plus strict background checks and procedural discipline for handling sensitive facilities. Manufacturers including Johnson Controls and Daikin Applied are opening new training institutes, set to open in 2027, to build up this workforce. Older data centers also need renovation roughly every seven years, adding more ongoing work. For homeowners, this doesn't change anything about your own equipment or rebates directly. But it points to a broader trend: as commercial and data center HVAC work grows more lucrative and specialized, the pool of technicians available for residential jobs like heat pump installations could tighten in some areas, something worth keeping in mind if you're planning a home upgrade and want to book installation time well ahead.
Designing Critical Facilities for a More Volatile Grid
This story is about hospitals, universities, and other large institutions, not individual houses, but it points to a trend worth knowing about. Engineers who design backup power for big facilities say the electric grid is getting less predictable as demand grows faster than expected, driven partly by data centers and more electric heating and cooling. A federal reliability group projects summer peak power demand will grow far more over the next decade than earlier estimates assumed. The core problem: extreme heat and cold often strain the grid at the exact moment buildings need the most power, and backup generators are usually sized only for a fraction of a building's systems, not everything. During events like Winter Storm Uri in 2021, frozen equipment and gas supply problems combined with power loss and even water pressure failures, showing how weather can hit several systems at once rather than one at a time. For homeowners, the direct takeaway is limited, but the underlying pattern matters: as more homes add heat pumps and other electric equipment, and as extreme heat and cold events become more common, local grids may face more stress during those same periods. That doesn't require any action on your part, but it helps explain why utilities and regulators increasingly talk about demand spikes during heat waves and cold snaps as a growing planning concern.
Changing The Narrative About Clean Energy — Dollars, Not Policies
A new wave of clean energy advocacy groups has shifted their pitch from environmental policy to household costs, and the change is playing out mostly at the state level. Groups like Deploy Action, Permit Power, PowerLines, and Utilize Coalition argue for cheaper electricity bills, a more efficient power grid, and fewer bureaucratic hurdles, rather than pushing any one technology like solar or wind. Because federal energy policy tends to swing with each administration, these groups are betting that state and local action is more durable, and that framing clean energy as a money-saver draws support from both parties. That approach has already produced real changes for homeowners in a few states. Connecticut and Virginia passed laws this year requiring an automated permitting system for home solar and battery installations, meant to cut the slow, paper-based approval process that can add thousands of dollars to a project's cost. Colorado legalized small balcony solar systems that plug into a regular outlet and became the first state to let certain rooftop solar setups connect to the grid without needing a utility agreement first. Virginia also passed a law directing utilities to study cheaper ways to add grid capacity, such as batteries and other technology, instead of automatically building new poles and wires. None of this guarantees anything for a given household, since these are state-specific programs and rules. But it signals that permitting delays and installation costs for home solar and batteries may keep easing in states that adopt similar measures, and it's worth checking what your own state is doing on this front.
U.S. exports of crude oil and petroleum products reached record in April
The U.S. hit a record for oil and petroleum exports in April, shipping out 13.6 million barrels a day, 15% more than the record set just the month before. The jump came after disruptions to international oil flows through the Strait of Hormuz pushed other countries to buy more from U.S. suppliers. Crude oil made up the biggest share of exports, followed by propane and diesel-type fuel, all setting or nearing records. Early estimates suggest exports of oil, diesel fuel, jet fuel, and propane stayed unusually high through May and June too. This is a national energy market story, not something tied to a specific home upgrade or rebate program. It does not change any incentive, price, or rule that homeowners deal with directly. But it is worth knowing about in a general sense: when U.S. fuel exports rise this much, it can tighten domestic supply of things like propane and diesel, which sometimes shows up as higher prices for heating fuel or transportation costs later in the year. If your home uses propane or oil heat, it is one more factor that could affect your fuel bill over time, alongside weather and the usual seasonal swings in demand.
ASHRAE Announces 2026–2027 Leadership, Award Recipients
ASHRAE, the professional group that sets many of the standards behind heating, cooling, and ventilation systems, has named new leadership for 2026-27. Sarah E. Maston takes over as Society president with a theme of "retrofitting for resilience," pointing to a broader push toward improving existing buildings rather than only new construction. Her priorities include raising awareness of building codes tied to resilience and encouraging better planning for how buildings operate day to day. For homeowners, this is mostly background news about who runs an industry organization, not a program or rebate you can apply for. But ASHRAE's standards and guidance do eventually shape the codes and equipment ratings that affect things like heat pump efficiency requirements, ventilation rules, and how contractors assess a home's performance. A renewed focus on retrofitting existing buildings suggests the group expects more attention on upgrading older homes for efficiency and resilience in the coming year, which could influence future codes or guidance you'd encounter when planning upgrades. The rest of the announcement covers awards given to individual members for technical and volunteer contributions, plus a list of newly elected board members and regional directors from around the country and abroad. None of this changes any rebate, deadline, or program you'd need to act on now. It's simply a look at who is steering the organization that helps set the technical rules of the HVAC world, with an eye toward retrofits becoming a bigger focus.
New Jersey increases transmission oversight in ‘affordability’ push
New Jersey Governor Mikie Sherrill signed three new laws aimed at holding down electricity bills, and they mostly affect how utilities plan and pay for the grid rather than anything homeowners need to do. One law puts new state review on "supplementary" transmission projects, the local upgrades utilities build outside the regional grid operator's planning process. These projects totaled $14.7 billion in New Jersey from 2008 to 2025, or 79% of transmission costs charged to ratepayers, and now utilities will need state approval before building them. Another law requires the state's utilities to join PJM, the regional grid operator, which strips them of an extra 0.5% profit margin they'd been earning for joining voluntarily. For PSE&G, the state's largest utility, that could mean about $40 million a year less in income. A third law sets up special billing rules for large data centers, requiring them to guarantee payment for most of the power they request over a long term and to help fund energy efficiency and clean power rather than passing those costs to regular customers. Alongside the new laws, Sherrill announced bill credits: $25 for all residential ratepayers through the Residential Universal Bill Credit program, plus an extra $150 for lower- and moderate-income households through the Residential Energy Assistance Payment program. Utilities involved include Rockland Electric, Atlantic City Electric, Jersey Central Power & Light and PSE&G. For homeowners in New Jersey served by these utilities, the practical upshot is a one-time credit on your bill and a broader effort to keep rising costs, especially from data centers and aging infrastructure, from landing on residential customers.
Duke Energy’s ‘light-touch’ large load tariff could be a problem.
Duke Energy, the utility serving the Carolinas, is asking regulators for an 11.6% residential rate hike, and part of that case includes a new rate structure for very large electricity users like data centers, starting in 2027. Customers with loads of 50 megawatts or more would sign 10 to 15 year contracts, pay for at least 75% of the power they request even if they don't use it, and post upfront collateral. Early exit would bring a penalty equal to 25% of remaining bills. The catch, according to industry analysts, is that Duke's plan groups data centers together with other big power users, like factories, instead of putting data centers in their own rate category. That makes it hard to see how much of the grid's rising costs come specifically from data centers versus other large industrial customers. Regulatory staff have proposed assigning about $200 million of a $247 million grid upgrade request directly to large-load customers, but Duke wants those costs spread across all customers, including regular households, arguing everyone benefits from the upgrades. This matters for homeowners because it affects who ultimately pays for grid upgrades driven by data center growth. If those costs get spread broadly rather than billed directly to the large users causing them, residential rates could absorb more of the expense. Other states are facing similar fights: Oregon just approved a roughly 29% rate hike for data center customers, while manufacturers in places like Ohio have already seen power bills jump due to nearby data center demand.
Daikin Debuts New Inverter-Driven Commercial Heat Pump
Daikin has introduced the Nexio Max, a new rooftop heat pump built for light commercial buildings rather than houses. It uses variable-speed ("inverter-driven") technology and a lower-impact refrigerant called R-32, and it comes in three sizes rated at 7.5, 8.5, and 10 tons of cooling capacity, up to 114,000 Btuh. Daikin says it holds up well in cold weather, still delivering 85% of its rated heating output at 14°F and running down to -13°F outside. This isn't a product for a typical single-family home. It's aimed at light commercial buildings, like small offices, shops, or similar structures, and is designed to bolt onto existing rooftop curbs and ductwork so building owners can swap out an old rooftop unit without major construction changes. It also connects to building management systems and Daikin's remote monitoring platform, features more relevant to commercial property managers than homeowners. The news is mainly useful as a sign of where heat pump technology is heading: manufacturers are pushing variable-speed compressors and lower-impact refrigerants into more categories of equipment, including commercial gear that previously ran on older technology. If you're weighing a heat pump for your own house, the relevant takeaway is that this same shift toward efficient, cold-climate-capable, low-GWP refrigerant systems is already well underway in the residential product lines most homeowners would actually buy.
How Tosi’s Sakari Suhonen is Rewriting the Rules of Building Automation Security
This news is about large commercial and multi-site properties, not typical single-family homes. Sakari Suhonen, CEO of Tosi US, a building automation security company, is raising concerns about how remote access to building control systems (the equipment that runs heating, cooling, and other automated systems) is managed across large real estate portfolios. He says many building operators still rely on old, shared logins that multiple contractors use to remotely access HVAC and other systems, often on networks that aren't well separated from other building systems. According to research from his company, about one in five real estate organizations can't fully track what's connected to their networks, which makes it hard to know who has access to critical equipment. The concern is that outdated access, like logins that never get shut off after a contractor's job ends or an employee leaves, can leave systems exposed, and the risk grows as companies manage many buildings at once. Suhonen argues for practices like giving each person their own login, setting access to expire automatically, and keeping records of who connected to what and when. For most homeowners, this doesn't directly apply, since it concerns large commercial building networks and property management companies overseeing many sites. But if you live in a large multifamily building or condo with a centrally managed automation system, this points to a security issue building owners and managers may need to address behind the scenes.
The NEWSMakers Podcast: PHCC Indiana Brings Pre-Apprentice HVAC Training to Hamilton County Jail
A trade group in Indiana, PHCC Indiana, has started a pilot program at the Hamilton County Jail that teaches inmates the basics of HVAC (heating, ventilation, and air conditioning) work before they're released. The program uses a pre-apprentice curriculum from PHCC Academy, combined with hands-on training, so participants can earn certificates and line up guaranteed job interviews once they finish. Chuck Gillespie of PHCC Indiana and Dan Quinonez of the PHCC Foundation discussed the effort on a recent podcast episode, talking about why trade work fits well with second-chance employment programs and how it might help ease the ongoing shortage of HVAC technicians. This isn't a program homeowners can sign up for or access directly. It's a workforce initiative aimed at training new technicians and helping former inmates find steady work in the trades after release. The people behind it hope it grows beyond this one jail and becomes a model other counties or states could adopt. For homeowners, the practical connection is indirect: efforts like this are part of a broader push to bring more people into HVAC careers at a time when finding a qualified technician for installs, repairs, or upgrades can mean a long wait. More technicians entering the field, from whatever training path, could eventually mean more availability when you need someone to service a furnace, install a heat pump, or handle other home heating and cooling work. There's no rebate, deadline, or program detail here that applies to your own house.
UNIGRID unveils 9.25-kWh sodium-ion battery for residential applications
A company called UNIGRID has started shipping its first home battery, called Na+Casa, to U.S. customers. Unlike most home batteries on the market, it uses sodium-ion chemistry instead of lithium-ion. The battery is rated at 9.25 kWh of storage capacity and is designed to last 25 years. It's built to work with most existing hybrid inverters, which the company says makes it easier to add to a solar setup you already have without swapping out other equipment. The main selling point of sodium-ion chemistry is safety and durability rather than performance. Because it has no lithium, UNIGRID says the battery cannot experience thermal propagation, the chain reaction that can cause lithium batteries to overheat and catch fire. It's also rated to operate across a wide temperature range, from -40°F to 140°F, so the company is pitching it as a good fit for homes in places with harsh winters, extreme heat, or unpredictable weather. Sodium is also more abundant than the lithium, cobalt, and nickel used in typical batteries, which UNIGRID argues could make supply chains more stable over time. For homeowners weighing a battery to pair with solar panels or to back up power during outages, this adds a new chemistry option to consider alongside standard lithium-ion systems, with claims of longer lifespan and broader temperature tolerance. No pricing was given.
Enphase debuts smart thermostat displaying home solar production
Enphase Energy is releasing a new smart thermostat called IQ Air that does more than control temperature. It also shows solar production, battery performance, and how much power your home is using, right on the wall display. The thermostat coordinates heating and cooling with your solar and battery system, adjusting based on how much power you're producing, your battery's charge level, time-of-use electricity rates (pricing that changes depending on when you use power), weather forecasts, and grid events tied to virtual power plant programs (setups where home batteries or devices help support the electric grid). IQ Air works with 24-volt HVAC systems and supports homes with multiple heating and cooling zones, each with its own temperature control. Enphase says it can be installed without a professional, with the company's app guiding setup step by step. For homes already using Enphase equipment or planning a solar installation, this thermostat could serve as an early piece of the system, installed even before solar panels go up. The thermostat is available for pre-order now through Enphase and its distribution partners, with shipping expected to start in August 2026. If your home already has, or is considering, an Enphase solar and battery setup, this is a new option for keeping an eye on your system's performance and possibly getting more efficient use out of your heating and cooling. No pricing was announced.
