Total Energy News – September 2026
This month's roundup touches on fuel costs, electric vehicles, and a utility merger fight, along with several Vermont energy events. A new estimate puts the cost of the recent Iran conflict at $100 billion in extra energy spending nationwide, working out to about $770 per household, with fuel prices expected to stay elevated for a while. Separately, a new study on electric vehicles found that switching from a gas car to an EV is a climate win in nearly all cases, even under assumptions designed to favor gas cars. A related data point from Vermont energy researchers illustrates the cost gap directly: $10 of gasoline at $3.59 a gallon covers about 65 miles, while $10 of electricity at the average residential rate covers 147 miles, and at a utility's special EV rate, 188 miles. On the policy side, New England governors, including Vermont's, have come out against a proposed merger of NextEra Energy and Dominion Energy, which would create the largest regulated electric utility in the country. The outcome could affect how utilities in the region are run and regulated, though no direct impact on individual bills has been spelled out yet. For Vermont homeowners, there are also several fall events worth knowing about, including free weatherization (sealing up drafts and insulating) and heat pump webinars hosted by Button Up Vermont on Wednesdays in October, covering topics like getting the most out of a heat pump and low-cost fixes that make a real difference in comfort and cost.
A New Standard in Flexibility & Efficiency
This news is about a commercial HVAC product, not something that applies to a typical house. Daikin has released an updated version of its VRV system, called VRV EMERION, aimed at office buildings. VRV stands for Variable Refrigerant Volume, a type of system used in larger commercial buildings that can heat and cool many different zones at once, using a network of indoor units connected by refrigerant piping. The new version switches to R-32, a refrigerant with a lower global warming potential than older refrigerants. To manage the safety concerns that come with R-32, the system adds components that shut off refrigerant flow at the zone level if a leak occurs, plus an optional ventilated enclosure for extra protection. These features are built for multi-story and high-rise office buildings, where long refrigerant piping runs and separate temperature zones for private offices, conference rooms, and common areas are common. For a homeowner, this doesn't translate into a product you would install. Residential heat pumps and mini-split systems use different equipment than the VRV systems built for large commercial spaces, so this update won't show up as an option for your house. It is still worth knowing that refrigerant regulations are pushing the whole HVAC industry, commercial and residential alike, toward lower-impact refrigerants like R-32, which may eventually influence the equipment offered for home heat pumps and air conditioners as well.
Trimming Existing Windows for Continuous Insulation
This isn't news you can act on at home — it's a homeowner posting a question on an online building forum, asking other builders for advice about a technical detail on his own renovation. The project: he's re-siding his house and adding 2 inches of rigid wood-fiber insulation (a board that wraps the outside of the walls to cut drafts and heat loss) over a water-resistant barrier, with a gap behind the siding for drainage and drying, then new fiber-cement siding. He's replacing some windows but keeping most of his existing vinyl windows, which sit in their original wood frames. Because the new insulation adds 2 inches of thickness to the wall, the trim around the kept windows needs to be built out to match, and window sills need to shed water properly so rot doesn't start again — he'd already cut back some old sills that were rotting or had lead paint. He's asking whether to build out the trim with plywood and dimensional lumber, whether to tape and reuse the old sill after flashing it, or to plane the old sill down to good wood and add fresh material, all while keeping the small weep holes (drainage gaps built into vinyl windows) clear. For a homeowner reading this, the takeaway is more conceptual than actionable: adding thick exterior insulation during a re-siding job changes how existing windows have to be trimmed and flashed, and getting the sill detail wrong risks water and rot problems down the line.
Court Rules TVA’s Decision to Build Kingston Gas Plant Broke the Law
A federal court has ruled that the Tennessee Valley Authority broke the law when it decided to build its Kingston Gas Plant, a large natural gas facility planned for the site of a 2008 coal ash spill in Tennessee. The U.S. District Court for the Eastern District of Tennessee found that TVA failed to properly study cleaner and cheaper alternatives before committing billions of ratepayer dollars to the project, violating the National Environmental Policy Act. The ruling throws out TVA's environmental review and its formal decision to move forward with the plant. The lawsuit was brought in 2024 by the Southern Environmental Law Center on behalf of Appalachian Voices, the Center for Biological Diversity, and Sierra Club. The EPA had also warned TVA years earlier that its environmental analysis was inadequate, but TVA went ahead with construction anyway. TVA has asked the court for permission to keep building despite the ruling. For homeowners in the Tennessee Valley served by TVA, this matters because it could affect what kind of power plants get built and how much that costs on monthly electric bills. Groups behind the lawsuit argue TVA should have weighed cheaper, cleaner options first, which they say would have been better for both electricity costs and air quality. The ruling requires TVA to reconsider its plans and properly evaluate alternatives, though what happens next with the Kingston plant itself is not yet settled.
Salvage First, Design Later: Mechanical Systems for a Low-Load Home
A Kansas couple building a house from salvaged materials ran into a common problem once their walls and roof turned out unusually airtight and well insulated: the heating and cooling load became so small that conventional duct systems no longer made sense. With very little air needing to move through the house, the team had to rethink comfort, humidity control, and ventilation (bringing in fresh outdoor air) together, rather than treating heating and cooling as the main event. The homeowners started out wanting a house with no floor vents and no air blowing directly on people — they pictured cool air dropping gently from above instead. As construction moved forward, though, equipment availability and the complexity of building a custom system pushed the team toward a simpler, more conventional setup than originally planned, while still keeping the low-draft, low-clutter feel they wanted. For homeowners doing their own upgrades, the lesson worth noting is less about salvaged materials and more about sequencing: a tightly sealed, well-insulated house changes what your heating and cooling system needs to do. Once air leaks and heat loss are minimized through better insulation and sealing, the equipment can often be smaller and simpler than what a typical house needs — but matching real-world equipment to that smaller load, while still managing moisture and fresh-air needs, takes some coordination. No specific costs, products, or rebate programs were mentioned for this project.
It Takes a Village to Procure an Electric School Bus
A small charter school in Winston-Salem, North Carolina, the Arts Based School, replaced its 20-year-old diesel school bus with an electric one, funded largely through the EPA's Clean School Bus Program. School leaders first explored the idea during a 2022 board retreat, then worked with the Piedmont Environmental Alliance and other partners to pull together an application, combining federal grant money with tax credits and utility rebates so the school didn't have to cover the full cost itself. The process wasn't quick. After winning the grant, the school bought the bus expecting reimbursement, but that federal payment was delayed almost a year, partly due to a change in federal administration. That meant the school had to cover the bus cost out of pocket in the meantime. Leaders there say any district pursuing this kind of grant should plan for a real gap between spending the money and getting reimbursed, and should have someone dedicated to managing the paperwork, deadlines, and communication with partners. Being part of the federal bus program also helped the school land additional clean-energy funding: it later added a 20 kilowatt solar array on one of its buildings through North Carolina's GreenPower Solar+Schools program, which nearly offsets the cost of charging the electric bus. For homeowners, this isn't a program you can apply for directly, but it's a reminder that federal and state clean-energy incentives can often be combined, or "stacked," to make a bigger project affordable, and that reimbursement-based grants can take much longer to pay out than expected.
RE+ 26 survival guide: What every attendee needs to know before heading to Las Vegas
This news is about RE+, a large solar and renewable energy trade show, not something that directly changes what's available to homeowners. But it's worth knowing about if you follow energy industry trends, since events like this are where companies announce new products and rebate programs. The show is moving from its usual September slot to November this year, and moving venues to the Las Vegas Convention Center. Organizers say the change avoids the worst of Vegas heat (September highs average 96 degrees, versus 70 in November) and gives the event more room to grow. The same week, Formula 1 racing will be happening in Las Vegas, but organizers say the convention center is far enough from the race track that it shouldn't cause problems for attendees, aside from possible travel delays getting to the airport on the last day. Other changes include separating the educational sessions (Monday through Wednesday) from the exhibit hall (Tuesday through Thursday), so attendees aren't choosing between the two at the same time. The show is also adding a partnership with a fleet and transportation event, and moving its networking party onto the convention center grounds instead of an offsite location. None of this changes any rebate, incentive, or program that affects your home directly. It's simply industry logistics for the people who attend the show each year, and the kind of event where new products or technology might get introduced.
Inside GM’s new battery lab — and its plans to challenge Asian rivals
GM is putting $900 million into a battery research campus in Warren, Michigan, aiming to build batteries in the U.S. instead of relying on Asian manufacturers like LG, Panasonic, CATL, and BYD. The company is developing two new battery types: LMR (lithium-manganese-rich), which could enable cheaper EV batteries with 400 miles of range, and sodium-ion, which holds promise for home and grid energy storage. GM expects to have LMR batteries ready by 2028, with a similar timeline for sodium-ion. Sodium-ion batteries matter for homeowners because they hold up well in both extreme heat and cold without needing extra cooling equipment, and they're less prone to fires since they burn at a lower temperature. Sodium is abundant and doesn't depend on the minerals China controls, which GM says could eventually make sodium-ion storage systems about 20% cheaper to own and run over their lifetime compared to standard lithium-ion. GM is also partnering with a company called Peak Energy to bring sodium-ion technology into storage systems. None of this changes what's available to buy today. GM hasn't picked a factory site for sodium-ion production yet, and the technology is still in early prototype stages. But if it succeeds, it could mean cheaper, more durable battery storage options down the road for homes pairing solar panels or backup power with the electrical grid, along with more EV choices built with U.S.-sourced batteries that qualify for federal tax credits.
Google, Xcel, others back MISO’s ‘zero injection’ large load proposal
A regional grid operator called MISO, which runs the power system across a swath of the Midwest and South from Louisiana to Minnesota, has proposed a faster approval process for power plants built specifically to serve big electricity users like data centers and crypto mining operations. Under the plan, projects that generate power at the same substation as the large user they're feeding, and that have little effect on the wider transmission grid, could get reviewed in 90 days instead of the usual long wait. Google, Xcel Energy, and several other utilities and clean energy groups have told federal regulators they support the idea, saying it will clear a backlog of interconnection requests. Not everyone agrees. The Sierra Club, the Natural Resources Defense Council, and other environmental and community groups say the plan lacks safeguards and could shift costs onto existing utility customers, meaning ordinary ratepayers could end up subsidizing infrastructure built for data centers. Federal regulators ordered grid operators nationwide to fix inadequate large-load interconnection rules by mid-November, and this MISO proposal is one response. This is a policy fight playing out in wholesale power markets, not a program homeowners can apply to. But if you live in MISO's territory, the outcome matters indirectly: it could affect whether new data centers strain the local grid and whether related costs eventually show up on residential electric bills. For now, there's nothing to sign up for or act on.
The race for space solar
This is a story about solar power in space, not on your roof, but it shows where solar technology is heading. Satellites have run on solar cells for decades, and investment in that market is picking up fast. The nonprofit Space Foundation says the global space economy hit $686 billion in 2025, growing 12% a year, and $28.7 billion in private money flowed into space companies in April 2026 alone. One deal: Denver's York Space Systems bought space-solar maker Solestial for $67 million. Two solar technologies are competing for this market. Older satellites use expensive gallium arsenide cells, which handle radiation well but are hard to produce in volume. Newer satellite fleets in low orbit, like Starlink, don't need to last as long or survive as much radiation, so cheaper crystalline-silicon cells (similar to what's likely on your own roof) are becoming more attractive, especially as rocket launch costs drop. Perovskite solar cells, an emerging technology also being developed for home use, are getting attention too, promising high efficiency at lower cost, though they still need to prove they can hold up over time. The U.S. Department of Energy has opened a $12 million grant program to fund research into space solar manufacturing, with applications open until October 8. None of this changes what's available for home solar or rebates right now, but it points to the same materials, silicon and perovskite cells, that could eventually show up in home solar products as the technology matures.
What’s next for the ISO net-zero standard
This is a story about corporate climate policy, not something that affects home energy upgrades directly. It concerns a new international standard for how big companies set and report "net-zero" emissions goals. The International Organization for Standardization (ISO) is developing a standard, called ISO 14060, that would set rules for large companies claiming to be "net zero" — meaning they cancel out as much greenhouse gas as they produce. The public comment period on the first draft closed September 9. National standards bodies from more than 170 countries had 12 weeks to weigh in, and now ISO will review that feedback. Depending on how much revision is needed, final approval isn't expected until early 2027. Critics, including a member of the ISO advisory group and researchers at the NewClimate Institute, say the draft has problems. It would require companies to publish a detailed two-year transition plan, which some worry exposes sensitive financial information and could scare off big businesses. Others say the standard is too complex and costly for smaller companies, particularly in developing countries, and that it lacks a firm deadline for companies to actually reach net zero — potentially letting large corporations delay real action indefinitely. None of this changes any home rebate program, tax credit, or upgrade option available to homeowners right now. It's a corporate accounting and reporting standard still years from finalized, with no direct bearing on household energy costs or improvements.
continuous insulation above grade interior face block wall climate zone 4A existing building
A homeowner in a 1960s house with a walk-out basement posted a question on a building-science forum about insulating the below-grade-turned-above-grade wall in that space. The wall is built from two layers of masonry: an outer layer of brick and an inner layer of concrete block (CMU). The homeowner already sealed the inside face of the block with a sealant product, creating what they describe as a continuous air barrier, and reports no water leaks into the basement. Now they're considering adding a layer of rigid insulation directly against the inside face of the block, without building out a stud wall. Options they're weighing include leftover polyiso foam (sometimes faced with foil), rigid mineral wool board, or newer XPS foam formulas. For the interior finish layer, they're thinking about skipping studs entirely and using thin vertical furring strips with a fiberglass-faced panel product, or some other panel system, though they haven't settled on one. The post asks two open questions: how much insulation (in R-value, the standard measure of how well insulation resists heat flow) would actually make a noticeable difference, and whether any specific panel systems would work well over this kind of setup. As of this posting, no answers had been given yet. If you have a similar basement wall — old masonry, walk-out design, above-grade portion exposed to outdoor temperatures — this is the kind of insulation upgrade worth researching further, since the right approach depends on your specific wall assembly and climate.
Georgia bet big on EV manufacturing. Trump pulled the plug.
Georgia spent years attracting electric vehicle and battery factories, with tax breaks and worker training bringing in Hyundai, Kia, Rivian, and Blue Bird's electric bus plant. Under the Trump administration, the outlook has shifted: the federal EV tax credit is gone, new tariffs hit battery packs and charging hardware, emissions rules have loosened, and the push to electrify government vehicle fleets has ended. A year ago, immigration agents raided an EV battery plant in the state and arrested more than 400 workers, mostly South Korean. In response, automakers are adjusting rather than pulling out. Kia's West Point plant now builds cars to order, gas, hybrid, or electric, and is currently leaning heavily on hybrids because that's what buyers want right now. Hyundai's nearby plant, originally built just for EVs, has added hybrid production too. Battery makers in the state are shifting some output toward home and grid storage batteries instead of only vehicle batteries. For homeowners, the most relevant thread is that battery storage manufacturing is expanding in Georgia even as vehicle battery demand wobbles, which could affect availability or pricing of storage batteries down the road. Georgia itself offers no state incentives for buying an EV, and actually charges EV owners an extra registration fee to offset lost gas tax revenue. So if you're weighing an EV or home battery purchase, any savings will depend on federal rules and whatever your state currently offers, not a Georgia-specific incentive.
5 NFL Stadiums Powered by Solar Energy
Solar power is showing up at some big venues this football season. Several NFL stadiums now generate part or all of their electricity from on-site solar panels, sometimes paired with battery storage. The Philadelphia Eagles' Lincoln Financial Field has more than 10,000 solar panels producing about 4 megawatts, covering roughly 40% of the stadium's yearly electricity use. In Las Vegas, Allegiant Stadium runs entirely on renewable power through a deal with the local utility, including a large solar-plus-storage project that pairs solar panels with batteries to store power for later use. Atlanta's Mercedes-Benz Stadium has over 4,000 panels generating enough electricity to cover all nine Falcons home games each year, with any extra power flowing back into the local grid for other customers to use. The San Francisco 49ers' Levi's Stadium built solar into its design when it opened in 2014, with panels that offset the electricity used during home games. MetLife Stadium, shared by the Giants and Jets, also uses on-site solar as part of its broader energy efforts. None of this is homeowner news exactly, but it reflects how ordinary solar and battery technology has become. The same basic setup — rooftop panels, sometimes paired with a battery — that powers these stadiums is the same technology available for houses, just at a much smaller scale.
We Recycle Solar to open panel recycling and critical material recovery facility in Texas
We Recycle Solar plans to open a new solar panel recycling plant outside Dallas, Texas, set to launch in 2027. The company says the facility will recover up to 96% of the silver, copper, silicon, aluminum, and glass found in old solar panels, turning them into materials that can be resold, all processed in the U.S. rather than shipped overseas. This is the first of five planned recycling sites the company intends to build across the country over the next four years, backed by about $100 million in investment. The goal is to create a network of regional recycling centers so old panels do not have to travel as far to be processed. We Recycle Solar already runs a similar plant in Yuma, Arizona. For homeowners, this news is mostly about the broader solar industry rather than something that changes your household right away. If you have rooftop solar now or are considering it, it is a sign that there will be more places to responsibly recycle panels once they wear out, rather than sending them to landfills. It does not affect current rebates, installation costs, or how your existing system works. But as more of these recycling facilities come online, it could make end-of-life disposal easier and more common for solar owners in the years ahead, and may support more U.S.-made components in the solar supply chain over time.
The Innovation That Built Cleats Manufacturing
This is a profile of Cleats Manufacturing, a Chicago-area sheet metal fabrication company, and its longtime leader Steve Passannante. It traces how the company grew from a small operation making duct connectors in 1964 into one of the largest HVAC ductwork fabricators in the Chicago area, recognized in the Congressional Record by its 50th anniversary in 2014. Over the decades, the company took on more of the work that used to happen on the jobsite, building rectangular duct, spiral pipe, welded duct and other components in its own shop instead, and investing in equipment and automation, including a modern plant with eight loading docks and duct lines that can run at the same time. For a homeowner, the piece is less about a specific product or program and more a look behind the scenes at where ductwork actually comes from. It's a reminder that the metal ducts running through your walls and attic are typically built in shops like this one, by fabricators who supply the contractors who install home HVAC systems, rather than assembled entirely on site. There's no rebate, deadline, or technology announcement here that affects your house directly. It's a story about a family-run manufacturer, its history, and the workers and relationships that keep it running, offered as background on the industry that builds the equipment behind your heating and cooling system.
Eight solar projects should bring Albuquerque to 100% renewable energy
Albuquerque is installing solar panels at eight city-owned sites, part of a push to get municipal operations to 100% renewable energy. The company Sustainability Partners is paying for the roughly 6 megawatts of solar equipment and will handle installation and upkeep, with the city paying monthly for its use instead of covering the full cost upfront. Energy Systems Group designed the systems, a mix of rooftop panels and solar carports, at locations including the Eastside Animal Shelter, Highland Pool, West Mesa Aquatic Center, Duke City BMX Park, Isotopes Park, the Ken Sanchez Transit Facility, the city's 911 Call Center, and the Albuquerque International Sunport. The Sunport site will also get 10 electric vehicle chargers and battery storage. Construction started last week at the Eastside Animal Shelter and Highland Pool, with the rest of the sites being built out through 2027. For homeowners, this isn't a program you can sign up for — it covers city buildings, not private houses. But it shows how a "pay over time instead of upfront" financing approach can make solar and EV charging more affordable for large facilities, similar in spirit to solar leasing or power-purchase agreements sometimes offered to homeowners. It's also a sign that your city government is investing in clean energy infrastructure, including EV charging, which may show up in local rebates, incentives, or charging access down the road. If you're weighing solar or an EV charger for your own home, this project doesn't directly change your options, but it's worth keeping an eye on whether Albuquerque expands any of these financing tools to residents.
Front-of-meter solar, storage could serve 32% of California’s 2032 peak load: study
A new study looks at how much of California's peak summer electricity demand could be covered by solar and battery projects built near existing power lines, rather than large-scale solar farms far away that need new transmission. The analysis, done by grid analytics firm Kevala for the Coalition for Community Solar Access, found that about 17.5 gigawatts of these local solar-plus-storage projects could cover roughly 32% of the peak demand expected on the grids of California's three big utilities (PG&E, Southern California Edison, and San Diego Gas & Electric) by 2032, during the hardest hours to meet: summer afternoons and evenings. This is a policy and planning study, not a program you can sign up for. It doesn't change your utility bill or offer you a rebate. But it matters because it points to a cheaper path for keeping the grid reliable as demand grows from electric cars, data centers, and other new uses. Building local solar and storage instead of expensive new transmission lines could help hold down the costs utilities pass on to customers through their bills. A related bill in the California legislature would direct the state's utility regulator to set up a program paying for this kind of local solar and storage; it's awaiting the governor's signature. If it becomes law, it could eventually shape how much of this generation gets built and how nearby communities benefit, though the study itself doesn't create any new rebate or incentive for individual homeowners.
NRDC at Climate Week NYC 2026: Meeting the Moment
The environmental group NRDC is holding a series of events during Climate Week NYC 2026, running September 20-24 in New York City. The organization's president, Manish Bapna, frames the week around accelerating clean energy, phasing out fossil fuels, and helping communities adapt to worsening heat, fires, floods, and storms. He points to falling costs for clean energy and faster-than-expected EV adoption as reasons for optimism, alongside warnings that global temperatures could cross the 1.5 degree Celsius warming threshold scientists have long flagged as dangerous, possibly within the next few years. Most of the sessions are policy discussions, panels, and networking events for advocates, companies, and policymakers rather than anything homeowners would attend directly. Topics include data centers and electricity demand, climate finance, protecting forests and oceans, and disaster resilience. One session, "Before the Next Disaster: Financing Retrofits that Keep Homes Insurable and Affordable," touches on home upgrades and insurance, though it's listed as invitation-only with no other details on financing programs or eligibility given. For homeowners, this is mainly background on the broader push toward clean energy and climate policy rather than a specific program or rebate you can act on. Nothing here changes what's available for insulation, heat pumps, or other home upgrades right now. If retrofit financing or insurance programs come out of these discussions, they would likely surface later as separate news with actual details on amounts and eligibility.
Belimo Energy Valve
This is a product spotlight, not really homeowner news. Belimo, a maker of HVAC control components, is marking the 10-plus year run of its "Energy Valve," a device first introduced in 2012. It's a control valve for hydronic heating and cooling systems (the kind that use hot or cold water piped through a building, common in large buildings and some homes with radiant heat or boilers) that also measures energy use and feeds data back to building operators. The piece is a manufacturer promotion tied to the trade publication's 100th anniversary, highlighting that the valve has gone through four generations of updates and won industry awards. For most homeowners, this has no direct bearing on your house. It's aimed at commercial and institutional buildings with complex hydronic systems, where facility managers use tools like this to fine-tune performance across large networks of pipes and zones. If your home has a boiler or radiant heating system, the same idea, that smarter valves and sensors can reduce wasted energy, applies in a general sense, but no specific product, rebate, or homeowner-facing program is mentioned here. There's no cost, availability, or residential retrofit detail to act on. It's simply a look back at one piece of commercial HVAC technology and how it evolved.
West Virginia regulators reject delay in review of NextEra’s MARL project
West Virginia's Public Service Commission has decided not to delay its review of a big new power line planned for the state. The MidAtlantic Resiliency Link, proposed by NextEra Energy Transmission, would run 107.5 miles, with about 60 of those miles in West Virginia. It's meant to help the regional power grid handle rising electricity demand — PJM Interconnection, which oversees the grid across a large swath of the mid-Atlantic and Midwest, projects West Virginia's peak summer demand will grow 8% to 12% over the next decade. Regulatory staff had asked to push back the hearing schedule to sort out concerns about the line's route, questions about whether it's really needed, and a related federal decision on how power-hungry data centers connect to the grid. The commission said no, so evidentiary hearings are still set for late October through early November, with a final decision expected in early 2027. For homeowners, this isn't a program you can sign up for or a rebate to claim. It's a large regional transmission project working its way through state approval — the kind of infrastructure that shapes long-term grid reliability and, indirectly, electricity rates in Pennsylvania, West Virginia, Maryland, and Virginia. If you live near the proposed route in West Virginia, this is a case worth keeping an eye on, since the route itself is still being finalized. For most other readers, it's simply a sign that regional grid upgrades tied to growing power demand are moving forward on schedule.
Better Solutions Begin with Better Conversations
This piece covers a conference for people who plan and build sustainable schools, not home upgrades. It's about an industry event called the Green Schools Conference, where architects, engineers, school district leaders, and technology companies meet to talk about things like indoor air quality and energy efficiency in school buildings. The 2027 conference is set for Feb. 8–10 in Austin, Texas. There's no news here about rebates, incentives, or upgrades for homeowners. The focus is on how companies that make products for schools use these conversations with educators and facilities staff to figure out what schools actually need, and on sponsorship opportunities for organizations that want to take part. If you're weighing energy upgrades for your own house, this doesn't change anything for you directly. It's worth knowing that similar conversations about indoor air quality and energy efficiency happening in schools often echo trends you'll eventually see in home products, too, but no specific program, rebate, or technology mentioned here applies to homeowners.
Repurposed EV batteries now delivering 28 MWh of grid services to ERCOT
A company called B2U Storage Solutions has built a new battery storage project near San Antonio that runs on used electric vehicle (EV) batteries. The project, called Bexar Martinez, is now sending 28 megawatt-hours of power to the Texas grid, operated by ERCOT, in the CPS Energy service area. Instead of scrapping EV batteries once they no longer hold enough charge for driving, B2U reuses them in large storage systems that help balance electricity supply and demand. With this project, B2U now runs 50 megawatt-hours of this kind of storage in Texas, plus more in California. Across both states, the company manages over 5,000 repurposed EV batteries and about 100 megawatt-hours of storage total. It plans to add more than 50 additional megawatt-hours in Texas over the next six months, aimed at supporting one of the fastest-growing parts of the state's power grid. This isn't a program homeowners can sign up for, but it points to where grid-scale storage is headed. Projects like this help utilities handle rising electricity demand at lower cost, which can factor into local electricity prices and grid reliability over time. The project also qualifies for a domestic content bonus under the federal Investment Tax Credit (ITC), a tax incentive tied to using US-made components, and has secured outside financing, suggesting this kind of reused-battery storage is becoming a proven, bankable technology rather than a one-off experiment.
Fractured
This piece is an opinion essay about the state of the green building movement, not a report on a new program or technology. It argues that groups working on sustainable building standards, certifications, and advocacy have become fragmented, with too much influence from corporate donors and industry interests, including fossil fuel companies sitting on nonprofit boards. The author says this competition and self-interest has eroded trust and weakened the movement's ability to push back against policies that work against environmental goals. The essay calls for the various organizations, certifying bodies, and advocates to set aside competition and unite around shared environmental values rather than business interests. It argues that real change requires rebuilding trust between people and organizations, not just new certifications or marketing campaigns. There is nothing here about specific rebates, deadlines, technologies, or programs that would affect a homeowner's own upgrade plans. It is a commentary on industry politics and direction, aimed at people who work within the green building field rather than at homeowners deciding on a project for their house.
Continuing post-Labor Day Green Deals hub – EVs, power stations, tools, smart devices, more [Updated]
This is a roundup of post-Labor Day sales on electric bikes, portable power stations, tools, and smart home devices, gathered from various retailers into one shopping list. It's a shopping deals post rather than a policy or product announcement, so there isn't a program, rebate, or technical change to weigh in on. For homeowners thinking about energy upgrades, the relevant category here is portable power stations, which some people use as backup power or to pair with solar panels, and smart home devices, which can include things like smart thermostats or plugs that help manage energy use. The post notes that many sales are running longer than the holiday itself, with some lasting through the week and beyond, though tool deals in particular don't have fixed end dates and prices could change without notice. Since this is a general deals hub covering a wide range of products rather than one specific item, there's no single price, model, or rebate detail to call out. If you're shopping for a power station or a smart device for your home's energy setup, it's worth checking current listings directly, since discounts on these kinds of sales events tend to shift day to day and vary by retailer.
Are GenCos a solve for the data center power problem?
A new utility structure called a "GenCo" is being tested as a way to power data centers without putting the cost on regular electric customers. Here's how it works: a utility sets up a separate subsidiary to build and own power plants dedicated to a specific data center, then sells that electricity to the parent utility through a contract, which resells it to the data center. Because the subsidiary isn't the utility itself, its costs and risks stay off the books that determine your electric rates. The first example is NIPSCO, a utility in Indiana, which got approval in September 2025 to create a generation subsidiary for large power users like Amazon and Alphabet's data centers. The process moved fast — a contract with Amazon was approved in about seven months, and a major power plant project (two large gas plants and a battery) got approved in under five months, far quicker than normal utility reviews. NiSource, NIPSCO's parent, says the deals could save residential customers over $1 billion. Other utilities, including FirstEnergy in West Virginia, are now considering the same approach. The structure isn't without concerns. Data centers still rely on the shared power grid — the poles and wires — so questions remain about who pays for that shared infrastructure. There are also worries about transparency, since these are individually negotiated contracts, and about what happens if a data center project falls through after a plant is built. Analysts say the model only works if the new subsidiary is kept financially separate from the main utility, with its own approvals for each deal. For homeowners, this is mostly background on how utilities are handling the surge in data center demand, rather than something requiring any action right now.
Johnson HVAC Distribution Unveils New Brand, Website
Johnson Supply, a company that sells heating and cooling equipment to contractors in Texas and Louisiana, has renamed itself Johnson HVAC Distribution and launched a new website. The change covers all of its more than 20 branches, plus two locations in Louisiana, and the company says another Texas location is on the way. Johnson has operated in the region since 1953 and is employee-owned. This is a business-side change rather than a shift in products or pricing. The company sells equipment to contractors, not directly to homeowners, so the rebrand itself has no bearing on your home's heating or cooling costs, rebates, or upgrade options. The new website is built mainly for contractors, offering easier access to product details, account tools, and branch information. If you're planning a heat pump installation, furnace replacement, or other HVAC work in Texas or Louisiana, you likely won't deal with Johnson directly, but the contractor you hire might buy equipment through this distributor. Nothing here changes what equipment is available, what it costs, or what rebates apply to your project. It's simply a name and website update for a regional supplier that stocks the parts and systems contractors install in homes like yours.
EVgo is adding 400+ fast chargers where you grocery shop
EVgo is putting in more than 400 new fast chargers for electric vehicles at shopping centers anchored by grocery stores. The chargers are going into properties owned by Regency Centers, a company that develops shopping plazas built around supermarkets like Publix, Kroger, Whole Foods, Trader Joe's, Safeway, and Albertsons. Planned locations span Colorado, Florida, Illinois, New Jersey, New York, Pennsylvania, Texas, Virginia, and other states, though no construction timeline has been announced. Each site will have up to 24 high-power fast chargers, which EVgo says can charge some EVs fully in as little as 15 minutes. The idea is to let drivers plug in while doing something they'd already be doing anyway, like grocery shopping or grabbing food, rather than making a special trip just to charge. EVgo says about half of drivers who stop at a charging site go into a nearby store or restaurant. This is EVgo's second phase of working with Regency: the first charger went in back in 2020, and the company now runs more than 150 charging stalls at Regency properties. The new additions will grow Regency's total charging footprint by more than 20 percent. For homeowners who drive or are considering an EV, this could mean more convenient, faster charging options popping up at your regular grocery store in the coming months, depending on whether your area is one of the states listed.
Senator claims Trump may open US market to Chinese EVs in Xi deal
A senator is raising concerns about a possible change to Chinese car imports, but this doesn't change anything about your home energy plans right now. Senator Elissa Slotkin says she's hearing rumors that the Trump administration might loosen restrictions on Chinese-made cars, including EVs, as part of a broader deal with China's president. She hasn't cited a source for this, and the White House hasn't announced any such plan. For context: Chinese EVs are currently blocked from the US market by a 100% tariff put in place under the Biden administration in 2024. Trump has kept that tariff in place and has spoken favorably of it, so there's no clear sign he plans to reverse course. Slotkin is also promoting her own bill, the Connected Vehicle Security Act, which would ban Chinese vehicles, software, and hardware from the US market and has already passed a Senate committee. None of this affects home energy upgrades, rebates, or EV buying decisions today. If you're considering an EV and thinking about charging it with home solar, that math doesn't change based on this rumor. Electricity rates have been rising, so pairing an EV with solar remains one way to keep fueling costs down, regardless of which car brands end up available in the US.
Greater Transport Electrification Could Cut Europe’s Import Dependency By Nearly A Quarter By 2040
A new analysis looks at how Europe's transport rules for the years after 2030 could shape whether the continent keeps buying imported oil or shifts more toward electricity made in Europe. The study, from the group Transport & Environment, argues that electric vehicles cut total energy use more than any liquid fuel alternative, including biofuels or synthetic "e-fuels," because electric motors are simply more efficient. That efficiency, the group says, makes electrification as much an energy security issue as a climate one. The analysis compares different paths the EU could take. If Europe keeps strong CO2 standards that push automakers toward electric cars, the region's dependence on imported fuel by 2040 could drop by nearly a quarter compared with today, and be about 15 percent lower than under a path with weaker EV rules. If those standards are loosened, Europe could still hit the same overall clean-fuel target, but only by leaning much more heavily on scarce alternative fuels that often have to be imported. The group argues those limited fuels would be better saved for planes and ships, which cannot easily run on batteries. This is a policy-level story about EU rulemaking, not a program with steps for homeowners to take. But it points to a broader trend worth watching: policies that favor electric cars over liquid fuels are likely to keep pushing EV costs down and charging options up across Europe, which can matter if you're weighing an EV purchase or comparing it with a gas or hybrid vehicle in the coming years.
Member spotlight: Bentley Mills, Inc.
This is a profile of Bentley Mills, a commercial carpet manufacturer based in California, highlighting its membership in the U.S. Green Building Council (USGBC), the group behind the LEED certification system for buildings. It's not a story about new rebates or programs for homeowners, but it does offer a window into how commercial building materials get evaluated for environmental impact. Bentley Mills says it buys 100% renewable electricity from its utility providers and purchases carbon offsets to cover emissions from the natural gas it uses in manufacturing. The company has earned certifications including Cradle to Cradle and NSF 140, which are standards used to assess how sustainably a product is made, and was among the first industrial manufacturers certified under LEED's rating system for operations and maintenance of existing buildings. Its sustainability director also pointed to a newer industry effort, the Common Materials Framework, developed with USGBC and the group mindful Materials, aimed at making it easier to compare the environmental claims of different building products using a shared set of terms. For homeowners, this doesn't translate into a rebate or direct upgrade you can pursue. It mainly reflects a broader trend in the building industry, where manufacturers are working toward clearer, more standardized ways of describing a product's environmental footprint. If you're ever choosing flooring or other building materials and want to compare their environmental claims, that kind of standardization is the backdrop making those comparisons somewhat easier over time.
Denmark Can Produce 140% Of Its Electricity Demand From Wind Power…So What Happens To The Extra 40%?
Denmark's wind turbines briefly generated 140% of the country's electricity demand early one morning last week, thanks to strong winds and low overnight demand. The extra power didn't go to waste — it was sold to neighboring grids. Denmark is now planning two offshore "energy islands" in the North and Baltic seas that will gather wind power from turbines at sea and send it to coastal grids, with some also used to produce green hydrogen (a clean fuel made using renewable electricity). Together the two hubs are expected to handle enough power for 5 million households. The US has similar offshore wind potential along its coasts, including floating turbine technology developed for deep water off Maine and the Pacific coast, plus ideas to convert old oil rigs in the Gulf of Mexico to renewable energy use. But the Trump administration has moved to block new offshore wind leases and has bought out some existing ones, slowing development mainly in states that had been building out these projects. None of this changes rebates or programs available to homeowners right now. It's a reminder that other countries are leaning harder into wind power while US offshore wind development stalls at the federal level. For your own home, the more relevant energy-efficiency and rebate programs are still the ones offered by your state and utility, which are worth checking directly since they vary by location.
Energy Vault Scaled Gravity Storage. The Battery Benchmark Is Brutal.
A large-scale test of "gravity storage" in China has come out looking expensive next to ordinary batteries. Energy Vault built a 148-meter tower in Rudong, China that stores energy by lifting and lowering 12,000 heavy concrete blocks, providing 25 MW of power for four hours (100 MWh total) — the same service a battery storage system provides. The idea is that raising blocks when electricity is cheap and lowering them later to generate power avoids the chemical wear-and-tear that batteries experience over time. But compared with a similarly sized Chinese battery installation delivering the same four-hour output, the tower needed roughly eight times the money to build, about thirteen times the upkeep cost, eleven times the land, and far more carbon emitted during construction. The battery system, using standard manufactured modules, fits in a small fraction of the space the tower requires. While the concrete blocks themselves are cheap and don't degrade the way batteries do, the surrounding machinery — the structure, foundations, lifts, motors, and controls needed to move them for decades — adds enormous cost and complexity. None of this touches your house directly. There's no rebate or technology here for homeowners to weigh. It's a reminder, though, that not every clean-energy engineering feat translates into a practical, affordable option — even when it works as designed, it can still lose badly on cost and land use to the batteries already being installed at scale.
Burying trees to save forests?
A company called Mast Reforestation has found a way to pay for replanting forests that burned in severe wildfires. After a bad fire, dead trees left standing are both a fire hazard and a huge cleanup cost, and land managers often can't afford to clear the land and plant new trees. There's also a shortage of conifer seeds needed to regrow these forests. Mast's approach: bury the fire-killed trees deep underground in sealed clay vaults with no oxygen, which locks away the carbon in that wood for good. Because this keeps carbon out of the atmosphere, it generates carbon credits the company can sell. That money then funds the expensive work of clearing burned land and hand-planting new, fire-resistant forests. This is a podcast episode about the company's founder and strategy, not a program homeowners can sign up for. It doesn't involve home energy upgrades, rebates, or anything that affects your house directly. It's worth knowing about mainly because it's a different way of dealing with the aftermath of Western wildfires, tying forest recovery to the carbon credit market instead of relying on government funding alone.
ARRAY Technologies opens its largest factory in New Mexico
ARRAY Technologies, a maker of solar tracker and racking systems (the equipment that tilts solar panels to follow the sun), has opened a new $50 million factory in Albuquerque, New Mexico. At 216,000 square feet, it's about three times the size of the company's previous site there and is expected to support around 300 jobs in production, design, engineering, and customer service. The company, which has been based in Albuquerque for more than 35 years, says the new plant lets it manufacture components in-house that it used to buy from outside suppliers. Some of those parts qualify for a federal manufacturing tax credit under Section 45X, part of the incentives meant to encourage building clean-energy equipment in the United States. The project also received public support, including $2.5 million from New Mexico's state job-creation fund and $250,000 each from the city of Albuquerque and Bernalillo County, plus a partial property-tax break. For homeowners, this is mainly a story about the solar supply chain rather than a program you can apply to. It doesn't create a new rebate or incentive for your own home. But more domestic manufacturing of tracker and racking hardware can matter down the line for the cost and availability of solar equipment used in larger installations, and it reflects a broader push to keep more solar-industry jobs and production in the U.S.
Yozma electric mini dirt bikes exclusive $595 savings, EcoFlow flash 2x 3,072Wh DELTA 3 Ultra power stations $1,800 off, EGO, more
This roundup covers a mix of deals on electric outdoor gear and home backup power, though most of it is aimed at recreational or yard equipment rather than whole-home energy upgrades. EcoFlow is running a 48-hour flash sale with up to 48% off, including two 3,072Wh DELTA 3 Ultra portable power stations for $1,299 each, with other units starting at $599. For anyone thinking about backup power for outages, these portable stations can run appliances or charge devices without being wired into your house. On the yard-equipment side, EGO has its 56V 21-inch cordless electric snow blower (auger-propelled, with two 7.5Ah batteries) at a 2026 low of $1,099, and Greenworks has a 40V cordless electric lawn edger down to $190. Both are battery-powered alternatives to gas equipment, which some homeowners choose to cut fuel use and maintenance around the house. There's also a discount on Yozma's electric mini dirt bikes, plus deals on a heated lunchbox and a small portable power bank with a built-in light, which are more personal-use gadgets than home upgrades. None of this ties to rebates or efficiency programs — it's retail pricing on electric-powered tools and portable batteries. If you're weighing battery backup or cutting gas-powered yard equipment, these are worth a look at these prices, but they don't affect any home energy program eligibility or savings you might already be pursuing.
Chinese & US Truckmakers Set To Gain Over A Quarter Of European Electric Truck Market By 2030
This one is about heavy trucks in Europe, not home upgrades, but it points to a broader trend worth knowing about. A new analysis from Transport & Environment finds that Chinese and US truckmakers could capture more than a quarter of Europe's electric heavy-truck market by 2030 if European manufacturers don't speed up their own shift to electric models. Zero-emission trucks made up 5.6% of European sales in 2025, double the year before, helped by EU emissions rules in force since July 2025 and falling battery prices. In Norway, Sweden, and the Netherlands, electric trucks already account for over 15% of new sales. The appeal of the new entrants comes down to cost. The analysis found that buying a Chinese electric truck instead of a European one can cut total cost of ownership by 12%, saving up to €43,000 over five years, while matching European trucks on range, charging time, payload, and efficiency. Since trucking runs on thin profit margins, that price gap matters a lot to buyers. For homeowners, this doesn't change anything about your own energy upgrades, rebates, or utility bills. It's a sign of how fast battery costs are dropping and how electrification is spreading well beyond passenger cars, into freight and heavy transport. The same falling battery and technology costs driving this shift are part of what's making home electric equipment, like heat pumps and induction stoves, steadily more affordable too.
Wendell Berry’s life on Earth
This isn't news about home energy upgrades or rebates, but a remembrance of writer and farmer Wendell Berry, who died last week at 92. Berry lived on a farm in Henry County, Kentucky, and wrote more than 50 books of poetry, fiction, and essays, mostly by hand. He believed that fixing environmental problems started with small, personal acts of care for the land, not just political pressure on lawmakers. Berry was also an environmental activist. He was arrested in 1979 for protesting a nuclear plant in Indiana and again in 2011 during a sit-in against mountaintop removal coal mining in Kentucky. In the 2010s he helped block a coal-fired power plant in Washington, D.C., and pulled his personal papers from the University of Kentucky after the school took a $7 million donation from a coal company. He also famously refused to own a computer, arguing in a 1987 essay that he didn't want technology to come between him and his work. His outlook didn't fit neatly into any political camp. He believed in strong families and communities but didn't think government should legislate personal life, and he saw humans and nature as deeply connected rather than separate. That view of small, steady, personal responsibility toward the land is the main thread of his legacy, though it doesn't translate into any specific step for homeowners to take.
Kia’s electric van now comes in 10 top hats, including a 7-seater and an upscale Prime model
This is car news, not a home energy story, but here's the gist: Kia has expanded its electric PV5 van into 10 different body styles, adding a 7-seater passenger version, a 5-seater, an upscale "Prime" model, a compact cargo version, and a chassis cab option. The PV5 is built on a modular electric platform that lets Kia swap body styles the way you'd swap Lego pieces, and it's become a strong seller in Europe and Korea since launching in late 2025, with over 39,000 sold globally this year so far. Kia is also about to reveal a larger sibling called the PV7 on September 14 at a trade show in Germany. Like the PV5, it will come in passenger and cargo versions, and Kia expects to offer similar variants, including a version comparable to the Prime trim. An even bigger model, the PV9, is planned for around 2030. All these vans will be built at a dedicated plant in South Korea capable of producing up to 200,000 electric vans a year. None of this involves home energy equipment, rebates, or efficiency programs. It's simply an update on Kia's electric van lineup for commercial and passenger use. If you're weighing upgrades for your own house, such as insulation, heat pumps, or electrical work, this news doesn't affect any of that.
The Importance of Strong Contractor-Supplier Relationships
This piece is a paid promotional feature about a business partnership between a Chicago painting company, DiVinci Painters, and its paint supplier, JC Licht, which sells Benjamin Moore products. It is not energy-efficiency news and has no direct bearing on home upgrades, rebates, or weatherization. The content centers on an exterior repainting job on a historic 1901 house in Illinois, where the crew used Benjamin Moore's Aura Exterior paint in a low-luster finish over previously painted cedar siding, trim, soffits, and windows. The company representatives praise the paint's durability, color retention, and bonding, along with the supplier's color-matching accuracy and reliable delivery. For a homeowner focused on energy upgrades, there is nothing actionable here: no rebate programs, no efficiency technology, no dollar figures, and no policy changes. It is essentially a case study on how a painting contractor and its paint supplier work together, framed as advertising content rather than reporting on home energy improvements.
Hyundai Motor Wins Three Honors at 2026 What Car? Electric Car Awards
Hyundai picked up three awards at the 2026 What Car? Electric Car Awards, a UK program judged by the publication's testers that recognizes the best new and used electrified vehicles on sale. The all-electric IONIQ 6 N was named Best Electric Performance Car, the current Tucson Plug-in Hybrid won Best Used Hybrid Family SUV, and the previous-generation Santa Fe took Best Used Hybrid Seven-Seat MPV. For anyone shopping used, the details matter more than the trophies. The Tucson Plug-in Hybrid pairs a 1.6-liter engine with a 13.8 kWh battery for up to 43.5 miles of electric-only range, and most used examples are still covered by Hyundai's original manufacturer warranty. The older Santa Fe, sold in the UK from 2018 to 2024, came with a 1.6-liter hybrid engine or a plug-in hybrid option, and cars up to five years old still carry Hyundai's five-year, unlimited-mileage warranty. Both points are worth knowing if you're weighing a used hybrid SUV against buying new, since warranty coverage and real-world electric range affect both running costs and resale peace of mind. This is a UK awards story, so the vehicles and warranty terms described apply to the UK market and may differ from what's offered in the US. If you're comparing electrified SUVs for your own driveway, the practical takeaways here are the battery range and warranty specifics, not the award itself.
Hyundai Fights Childhood Cancer — But How Much Does It Really?
Hyundai recently marked 28 years of donations through its Hope on Wheels charity, which funds pediatric cancer research and care. The automaker says it has given $303 million over that time, with support from its more than 855 US dealers. It held a gala in Washington, D.C. to celebrate the milestone, drawing company executives, dealers, members of Congress, researchers, and families affected by childhood cancer. This is a corporate charity story, not a home energy program, so there's nothing here that affects rebates, upgrades, or your household budget. The commentary raised a separate point worth knowing about if you're weighing vehicle choices: gas-powered cars produce pollution that has long been linked to cancer risk, including in children, and Hyundai's electric vehicle sales still make up a small share of what it sells overall, similar to other big mass-market automakers. Notably, the company used an electric vehicle for the charity event's publicity photos even though most of what it manufactures and sells remains gas-powered. For homeowners thinking about their own energy and transportation choices, this is a reminder that a company's public charitable giving and its actual product lineup can tell different stories. If you're considering an EV as part of a broader push to cut fossil fuel use at home, this piece doesn't change any specific rebate or program, but it's a data point on how one major automaker's clean-energy transition is actually progressing.
BYD Sales Outside of China Grew 134% to Record 189,466 Vehicles in August — But BYD Aims Much Higher for 2027
BYD, the Chinese electric vehicle maker, sold 189,466 vehicles outside China in August, up 134.5% from a year earlier and a new record for the company. That growth comes as the Chinese car market has cooled, pushing BYD to look abroad for buyers. The company now wants to sell 2.5 million vehicles outside China in 2027, a big jump from the roughly 1.74 million pace it's on for 2026. Part of that plan involves building cars closer to where they'll be sold. BYD's plant in Hungary is expected to start assembly in November or December, and the company is looking at other overseas manufacturing sites. Building locally would let BYD avoid the European Union's roughly 27% tariff on battery electric vehicles and Brazil's 34% import tariff, savings estimated at more than $5,900 per vehicle. BYD is also growing at home, aiming to raise its share of the Chinese auto market from about 18% now to 25%. For homeowners, this is mostly background on the broader EV market rather than news that changes anything at your house right now. If you're weighing an EV purchase alongside other home energy upgrades, like a heat pump or rooftop solar, it's a sign that Chinese-made EVs are becoming more available globally and that manufacturing is shifting toward more markets, including Europe and possibly beyond. Whether that eventually affects EV prices or availability where you live isn't something this news settles.
Hyundai Tries To Win Over More Europeans By Sponsoring UEFA Champions League
Hyundai has signed on as the official automotive sponsor of the UEFA Champions League, Europe's top club soccer competition, starting with the 2026/27 season. The deal is really a marketing push tied to a new electric car: the IONIQ 3, a compact electric hatchback built for European buyers. It's the first of five new models Hyundai plans to bring to Europe this season, and Hyundai says it offers up to 497 kilometers of range on the WLTP test cycle (Europe's official mileage-and-range rating), along with a roomy interior and a 14.6-inch display. None of this changes what's available in US showrooms. Hyundai has said the IONIQ 3 is built for the European market, and its US lineup and sponsorship efforts (like its recent World Cup deal) have leaned more toward gas-powered cars and SUVs. So this is mainly a signal of where Hyundai is putting its electric-vehicle energy right now, not a preview of a new EV option for American driveways. For a homeowner thinking about their own electric vehicle purchase, or how it might tie into home charging and energy plans, the practical takeaway is limited: this is a European product launch and sponsorship deal, not a US rollout. If you're weighing an EV purchase, it's still worth checking what Hyundai currently sells in the US and pairing that decision with any home charger or electricity rate planning, but the IONIQ 3 itself isn't part of that picture yet.
BYD cuts Denza Z9 GT EV prices with the new e3 Premium trim, starting at about $50,000
This is car news, not a home energy story, so it won't affect your house or any rebate plans. But here's what happened: BYD's Denza brand rolled out a cheaper version of its Z9 GT electric luxury car in China, called the e3 Premium trim. The new trim starts at 329,800 yuan, about $49,000, roughly $6,000 less than the top Performance version, which starts at $55,000. Both use three electric motors producing a combined 1,032 horsepower, but the Performance model is slightly quicker (2.7 seconds versus 2.8 seconds for 0 to 62 mph). The cheaper Premium trim actually has a longer estimated range, up to 534 miles on China's testing standard, compared to 509 miles for the Performance version. It uses a 122.5 kWh battery and supports fast charging that can take it from 10% to 70% in 5 minutes. To hit the lower price, BYD swapped in cast-iron brakes and different wheels instead of the pricier carbon-ceramic brakes on the Performance trim. This car is sold in China now, and BYD's Z9 GT is already available in Europe and the UK at much higher prices, starting around $134,000 in Germany. Whether this new, cheaper Premium trim will come to those markets, or to the US, has not been announced. For now, this is a China-only price cut on a luxury EV, with no clear tie to any home energy program or rebate.
Data confirms Autopilot/FSD was active in crash that killed a mother, passerby saved her baby
A Tesla Model Y crashed on an Alabama highway in December, killing the 29-year-old driver, Kayleigh Page, and injuring her infant daughter, who was pulled from the burning car by a passerby. State troopers logged it as a routine single-vehicle wreck and never mentioned any driver-assist system. But federal crash data filed by Tesla shows the car's Autopilot or "Full Self-Driving" system was "Verified Engaged" at the time, meaning Tesla's own telematics confirmed it was active. The car was going 55 mph when it left the road and struck two trees. Tesla's filing left out the details that would explain what went wrong: the narrative of the crash, which software version was running, and whether the road was even approved for the system to operate on. Those fields were redacted as confidential, which Tesla does in nearly all of its crash reports to federal regulators. So there's no way to know from public records whether basic Autopilot or the more advanced FSD was steering, or why the car drifted off the highway. This case fits a broader pattern: among Tesla driver-assist crashes with disclosed details, the single most common type is the car leaving its lane or the road entirely, more often than rear-end collisions or turns. If you own or are considering a car with these systems, the takeaway from this incident is a reminder that they are supervised driving aids, not self-driving systems, regardless of how the software is marketed or what a company's executives say about it.
RGNT’s 85 MPH retro electric motorcycle just got a scrambler makeover
This isn't really home energy upgrade news, but here's the gist for anyone interested in electric vehicles: Swedish maker RGNT has added a scrambler version to its retro-styled electric motorcycle lineup. The Street Scrambler shares the same 46 kW hub motor as the existing Street Classic, with a claimed top speed of 84 mph and a 0-62 mph time of 3.9 seconds. What's different is a bigger 18-inch front wheel with chunkier off-road tires, a taller and wider handlebar, and more ground clearance, changes meant to make the bike more comfortable on gravel roads and light trails while keeping its vintage look. Battery options are the same as the Classic: a standard 8.3 kWh pack rated for 86 miles of range, or an optional larger 10.1 kWh pack good for 106 miles. The battery is fixed rather than removable, and charging uses a European-standard Type 2 plug. The stock charger takes about four and a half hours for a full charge, while an optional faster charger cuts that to roughly an hour and a half, or about 50 minutes for a 20-80% top-up. Pricing starts at €9,495, about €500 more than the Classic. The bikes are sold in Europe for now, but the company has said it plans to bring them to the US in 2027, with a starting price around $9,995. If that timeline holds, this could eventually be an option for US buyers shopping for an electric motorcycle rather than a car-focused EV.
Here’s our first look at Nissan’s new entry-level Pixo EV [Images]
This is car news, not a home energy story, but here's the gist. Nissan is bringing back a small, low-cost electric car called the Pixo, aimed at buyers who want an affordable EV rather than a big SUV. It's expected to launch in Europe in the first half of 2027, with prices starting under €20,000 (about $23,200) before any subsidies or incentives, and a fuller reveal planned for September 23. Early spy photos show a heavily disguised test car that appears to share its underpinnings with the Renault Twingo. Nissan hasn't confirmed technical details, but reports point to a 27.5 kWh battery using lithium iron phosphate (LFP) chemistry, a common lower-cost, long-lasting battery type, paired with a single electric motor producing about 82 horsepower. That setup is expected to give a range of roughly 163 miles on the European testing standard. The car would be built alongside the Twingo at a Renault plant in Slovakia. There's no indication this car is planned for sale in the United States, so it isn't something to factor into any home charging or EV purchase plans if you're in the US. If you're weighing a home charger install or curious how a new EV might fit your household's energy setup, this particular model likely won't be an option here — it's aimed at European buyers looking for a smaller, cheaper city car.
The Democracy We Must Protect Together
This piece doesn't fit Retrofit Relay's focus on home energy upgrades and rebates. It's a commentary on democracy and authoritarianism, arguing that threats to the rule of law, free elections, civil society, and peaceful conflict resolution show up as a pattern rather than isolated incidents, and calling for people across political views to unite around those basic democratic commitments. There's no news here about heat pumps, weatherization, rebate programs, or anything else that would affect a homeowner's plans for energy-efficiency upgrades. Since it doesn't touch on home energy topics, dollar amounts, program deadlines, or state-level rebate rules, there isn't a homeowner-relevant summary to give.
GameChange Energy responds to Nextpower lawsuit with another lawsuit
Two big makers of solar tracker systems — the motorized mounts that tilt rooftop and ground solar panels to follow the sun — are now suing each other over patents. This is a business dispute between manufacturers, not a program or rebate change, so it doesn't require any action from homeowners. But it's worth knowing about if you're weighing solar equipment from either company. GameChange Energy has sued Nextpower, claiming Nextpower's NX Horizon tracker (with a feature called Hail Pro) copies a GameChange patent for "self-shielding" trackers. That design tilts panel rows steeply, 60 to 80 degrees, when winds hit 70 mph or higher, to reduce wind damage to the array. GameChange got the patent in October 2025 and is now seeking money damages and a jury trial. This follows an earlier lawsuit from June, in which Nextpower sued GameChange first, claiming GameChange's Genius Tracker infringes three of its own patents covering self-powered tracker components and software. For most homeowners this dispute won't change anything about installing solar, since these tracker systems are mainly used in larger ground-mounted arrays rather than typical residential rooftop setups. But if a legal ruling eventually restricts either company's tracker designs, it could affect equipment availability or pricing down the line. For now, there's nothing to do but watch how the cases play out.
