An alternative vision of residential flexibility for data centers
Three companies that manage smart home energy devices — Renew Home, Tesla, and Sunrun — say they can offer a combined 16 gigawatts of power capacity to data center companies. The idea is to use smart thermostats, home batteries, and solar systems already installed in homes to shift electricity demand and ease pressure on the grid as data centers driving the AI boom strain power supplies. Renew Home, which grew out of Google, manages around 9 gigawatts of home devices, mostly smart thermostats. Most customers with these devices are not enrolled in any special utility program. Instead, when someone sets up a smart thermostat through Renew Home, the company can automatically adjust things like pre-cooling a home before peak-price hours to save energy costs. That same flexibility, the companies argue, can also be packaged and sold to data center operators or utilities without changing anything the homeowner sees or does. In other words, hyperscalers (large tech companies operating data centers) could end up indirectly funding the rewards homeowners get, replacing or supplementing what utilities have historically paid. For now, the practical plan includes bidding one gigawatt of this flexible capacity into an upcoming emergency power procurement in the PJM grid region, which covers much of the mid-Atlantic and Midwest. If you already have a smart thermostat, battery, or solar system enrolled with one of these companies, this news mostly means your device's flexibility could soon be used for a new purpose — supporting data center power needs — without requiring you to sign up for anything new or change your daily routine.
ACC Finalizes Repeal of Energy Efficiency Rules
The Arizona Corporation Commission has voted to eliminate the state's Electric Energy Efficiency Standards, ending a rule that required utilities like Arizona Public Service and Tucson Electric Power to offer programs helping customers cut energy use and lower bills. The repeal process began in 2025 and is now final. If you're a customer of one of these utilities, this matters because those efficiency programs often provided a path to help pay for insulation, appliance upgrades, or other home improvements that lower electric bills. Without the requirement, utilities have less reason to keep funding them. Critics, including the Sierra Club and an economic analysis done for the Commission itself, warn this will likely push electricity use and long-term bills higher, since utilities may instead invest in new power plants, with those costs passed on to ratepayers. This follows an earlier ACC vote to repeal Arizona's Renewable Energy Standard and Tariff, which had supported solar development in the state. Together, the two rollbacks mean Arizona utilities now face less pressure to invest in either efficiency programs or renewable generation. For Arizona homeowners, this doesn't change anything about your house today, but it may mean fewer or smaller utility-run rebate and efficiency programs going forward, and a higher chance of rate increases over time. If you live in Arizona, it's worth keeping an eye on what programs your specific utility still offers, since availability may shift as this policy takes effect.
The real ROI of distributed energy lies beyond the spreadsheet
This news is about commercial and industrial buildings, not homes, but it points to a trend worth knowing about: electricity rates for businesses have climbed sharply in some states. In Massachusetts, average commercial electricity rates rose from about 13.0 cents per kilowatt-hour in 2014 to 20.9 cents in 2024, a 61 percent jump, well above the 2024 national average of roughly 13.9 cents. Industrial rates in the state rose a similar amount. Rising rates like these are often driven by grid upgrades, growing electricity demand, and data center growth, forces that can affect residential rates too, even though this analysis focuses on businesses. The article compares two setups for a Massachusetts facility: a battery alone, and solar panels paired with a battery. In the modeled case, solar-plus-battery came out ahead on every financial measure, paying back faster and delivering a better return, mainly because onsite solar cuts grid purchases directly, while a battery alone still has to charge from the grid at a cost. The analysis stresses that not all savings are equally reliable. Savings from generating your own power are the most dependable, while revenue from utility programs or wholesale energy markets is more likely to shift over time. For a homeowner, the takeaway is not a specific rebate or deadline, but a reminder that battery storage without solar has real trade-offs, and pairing solar with a battery tends to produce steadier savings than storage alone. If you are weighing either option, it is worth checking your own utility's rate trends and any state-specific incentive programs before deciding what fits your house.
Duke reduces rate hike request, still faces regulator pushback
Duke Energy has lowered its proposed residential electricity rate increase in North Carolina to 11.6%, down from an original request of 18%, after pushback from customers and the state Attorney General. Even at the reduced level, the request faced tough questions from state regulators during a recent hearing, with commissioners and consumer advocates pressing Duke on whether homeowners are being asked to shoulder costs that mainly benefit large industrial customers. A central issue is data centers. One commissioner noted that 70% of Duke's queue of large new electricity users is data centers, and questioned how residential customers are expected to help fund roughly $100 billion in planned utility investments through 2035 when those centers appear to be highly profitable for Duke. A lawyer representing consumer groups pointed to utility data showing that about 98% of the financial benefits from certain grid upgrade projects went to non-residential customers, raising questions about whether homeowners are paying for improvements that mostly serve big commercial users. Duke has defended the rate request, saying a lower return on equity could hurt its credit rating, which the utility argues would eventually raise borrowing costs and rates for everyone, including after storm recovery efforts like those following Hurricane Helene. The state commission is expected to decide on the case by September 20. If you get power from Duke in North Carolina, this case will determine how much your monthly bill goes up.
Big Temps, Big Storms, and Climate Change: Talking About Extreme Event Attribution
This is a science explainer, not a story about home upgrades, but it helps make sense of why "climate change" gets blamed for the heat waves, storms, and wildfires many homeowners are now planning around. The field is called extreme event attribution, and it works by comparing what actually happened in a heat wave, storm, or fire to what computer models say would have happened in a world without human-caused warming. The first such study, in 2004, looked at a deadly European heat wave and found climate change had more than doubled its likelihood. Since then, researchers have found climate change tripled the odds of extreme rain during Hurricane Harvey, added over 3 degrees to the 2021 Pacific Northwest heat wave, and made the fire weather behind the January 2025 Los Angeles wildfires 35 percent more likely. Some events are easier to pin on climate change than others. Heat waves are the clearest case, because they track closely with rising temperatures. Hurricanes and wildfires are messier, since things like forest management and storm formation add complexity, but scientists can still point to warmer oceans, higher sea levels, and drier conditions as climate-driven factors that make these events worse. None of this changes any rebate or program details, but it is useful background for understanding why extreme heat, heavier storms, and wildfire risk keep showing up in conversations about home upgrades like better insulation, air sealing, or heat pumps.
My First Week of Making Solar Electricity
A homeowner and building science writer recently had rooftop solar panels turned on at his Georgia home, and his first week of results offer a real-world look at what to expect from a home solar system. He installed a 9.72-kilowatt system with 26 panels in December 2025, partly to catch the 30 percent federal solar tax credit before it expired at the end of that year. It took 135 days from installation to getting utility approval to actually operate the system, since the utility had to test it first. In the first eight days of operation, the system made just over 300 kilowatt-hours of electricity, with a peak output of about 8 kilowatts on sunny days, close to but not always reaching its rated capacity. To size the system, he looked at his household's electricity use over several years (roughly 12,000 to 16,000 kilowatt-hours annually) and used a free online tool, PVWatts, to estimate output before choosing panels and an inverter. One complication: his utility does not offer full net metering, meaning he is paid about half as much for the solar electricity he sends back to the grid as he pays for power he buys. That makes it more valuable to use the solar power himself, such as running laundry during sunny hours, rather than selling it back. He plans to add a battery later to store extra daytime power for use at night. His experience is a reminder that solar economics depend heavily on how your local utility handles selling power back to the grid, which varies by state and provider.
The Unlocked Efficiency Opportunity of On-site Power
This news is about data centers, not homes, but it points to a bigger trend worth knowing about: as AI-driven data centers strain local power grids, more of them are generating their own electricity on site rather than waiting years for a grid connection. That on-site power comes from systems like gas engines or fuel cells, which throw off a lot of heat as a byproduct. The interesting part is what happens to that waste heat. Instead of losing it, some data centers are feeding it into absorption chillers, a cooling technology that uses heat (instead of electricity) to produce chilled water. This can cut a cooling system's electricity use dramatically and also reduce water use, since the same water isn't being evaporated twice, once for power generation and again for cooling. In Europe, regulations are starting to require data centers to reuse a share of their waste heat, and similar systems already send recovered heat into regional heating networks that serve thousands of households. For a homeowner, this isn't something to act on directly. It's a sign that "waste heat recovery" is becoming a serious efficiency strategy at the industrial scale, the same basic idea behind heat pump water heaters and other equipment that recycles heat instead of discarding it. It doesn't change what's available for your house today, but it reflects the same efficiency logic increasingly built into home equipment.
Software Gives Contractors a Window into Home Systems
A software company called Sendal has launched a new monitoring tool, Sendal Aware, for HVAC and home service companies. The system watches a home's heating and cooling equipment for signs of trouble, such as a system not responding normally, excess heat or humidity, mold risk, power outages, indoor air quality problems, and water pooling in a drain pan (a common early sign of a failing air conditioner). When it spots something off, it alerts the contractor and, when needed, the homeowner too. The idea is to catch problems before they turn into full breakdowns, so a contractor can respond faster instead of you only calling when the system has already failed. It also builds on two earlier Sendal products, Breathe and Balance, which handle air quality and whole-home humidity control and have kept more than 98% of customers year over year, according to the company. For homeowners, this is mainly a look at where the industry is heading rather than something to sign up for directly. Aware is a service contractors can offer, not a product you'd buy on your own. If your HVAC company adopts something like this, it could mean earlier warnings about a struggling system, or ongoing check-ins between regular service visits, rather than a surprise breakdown in the middle of a heat wave. Whether it shows up for your home depends on whether your local contractor decides to use it.
Palmetto opens battery-only lease plan to all residential contractors
A company called Palmetto has rolled out a new way to add battery backup to a home without paying for it upfront. Normally, buying a home battery outright can cost more than $16,000. Palmetto's new option, called the Energy Backup Plan, is a 12-year subscription instead: you get the battery hardware installed with no upfront payment, and Palmetto handles maintenance and repairs over the life of the plan. It's now available in 25 states, with more expected. This matters because solar panels alone usually don't keep your lights on during a power outage. Most home solar systems automatically shut off when the grid goes down, so a battery is what actually lets you keep power flowing to your house when utility service is interrupted. Through Palmetto's app, homeowners can set how much backup reserve they want to keep in the battery, and can also use stored energy to avoid paying peak utility rates at certain times of day, a practice sometimes called energy arbitrage. The plan can be added on its own or as an upgrade to an existing solar system, and it works whether you already have solar installed or are considering it. If you already own solar panels and have wondered about adding battery backup without a large upfront cost, this is the kind of option worth asking about, including whether it's offered by installers in your state.
New York reaches 8 GW of distributed solar capacity
New York has installed 8 gigawatts of small-scale solar across the state, mostly rooftop and community solar systems rather than big power plants. Gov. Kathy Hochul announced the milestone on July 2, saying the state is ahead of pace to hit its goal of 10 GW by 2030. More than 276,000 individual solar projects make up that total, with another 2.7 GW in the pipeline. Officials say the current capacity generates enough power for 1.3 million homes and businesses, and 2025 was the state's biggest single year yet for solar installations, at 1.28 GW. Much of this growth traces back to NY-Sun, a state program that offers financial incentives for home, business, and larger solar projects. New York's 2027 budget sets aside $200 million for the program, which the Solar Energy Industries Association estimates will fund roughly another 1 GW of rooftop and community solar. If you live in New York, that means the incentive program behind much of this growth is still funded and running, and it's worth checking what NY-Sun currently offers for your home. Outside experts point to two things behind New York's results: steady, predictable incentives through NY-Sun, and a standardized process for connecting solar projects to the grid, which cuts delays and costs for smaller installations. Homeowners in other states won't see NY-Sun's incentives directly, but the takeaway is that clear rules and stable funding tend to speed up solar adoption. If your state has a similar solar incentive program, it's worth checking what's currently available.
Eaton is preferred smart breaker supplier for FranklinWH
Two companies that make home battery and electrical equipment are teaming up to make home battery systems smarter. Eaton and FranklinWH have paired Eaton's AbleEdge smart breakers with FranklinWH's home battery systems, and Eaton is now FranklinWH's preferred supplier for this kind of equipment. Smart breakers work like standard circuit breakers but add remote monitoring and control, so a homeowner can see and manage which appliances or circuits are drawing power. For a house with a FranklinWH battery, this combination is meant to give more control over which loads (appliances or circuits) run during a power outage, potentially stretching backup power longer, and to support "virtual power plant" programs, where utilities can tap home batteries to help balance the grid. The breakers can be added to existing electrical panels in a retrofit or installed in new construction, and they connect through FranklinWH's Meter Adapter Controller. Homeowners would manage everything through the FranklinWH app, which is used to install, monitor, and control both the battery and the smart breakers. This is a product partnership announcement rather than a program with specific dollar incentives or deadlines. If you already have or are considering a FranklinWH battery system, this means you may have an easier path to add smart, app-controlled circuit management alongside it, whether you're upgrading an existing setup or building new.
Microsoft adjusts climate agenda as emissions leap
Microsoft's greenhouse gas emissions rose 25 percent in its 2025 fiscal year, driven by a rush to build data centers and line up electricity for artificial intelligence and cloud computing. Google and Amazon reported similar jumps, 18 percent and 16 percent, in their own recent sustainability updates. Microsoft says it will stick with its climate goals, arguing emissions would have grown even more without efficiency work already underway. Much of the increase traces to electricity: Microsoft used 37 million megawatt-hours of power in 2025, up 24 percent from the year before, enough to run 3.4 million U.S. homes for a year. The company also changed how it accounts for renewable energy credits, which made its electricity-related emissions look larger on paper. Microsoft continues to sign large contracts for wind and solar (it now has deals for 40 gigawatts) but has also turned to new natural gas plants for some data center projects, and it's investing in nuclear, geothermal, and smaller local clean-energy projects near data centers in 100 communities across 20 states. None of this changes rebates or programs available to homeowners. It mainly shows how much electricity demand is climbing nationally as tech companies expand AI infrastructure, which can affect regional power supply and grid planning over time. Microsoft also remains the largest corporate buyer of carbon removal credits, signing deals in 2025 meant to offset tens of millions of tons of emissions over the next three decades, and says despite recent reports, it has not paused that work.
Hawaiʻi committed to 100% clean energy. Now it’s flirting with natural gas.
Hawaiʻi passed a law in 2015 committing the state to 100% renewable electricity by 2045. A decade later, the buildout has been slowed by the pandemic, supply chain problems, and the 2023 Maui wildfires, which were linked to utility equipment and hurt Hawaiian Electric's finances. Rooftop solar has grown widely, especially on Oʻahu, but electric rates remain the highest in the nation, and residents without solar are still exposed to swings in global oil prices. Now Gov. Josh Green is backing a $2 billion proposal from Japan's JERA to build a floating terminal that would import liquefied natural gas (LNG) near Barbers Point on Oʻahu, fueling a new power plant meant to come online by 2030. JERA says the switch from oil to gas could cut household bills by $500 a year. But independent energy researchers and a state senator who helped write the 2045 law argue the real savings would be small, and that gas ties Hawaiʻi to another imported fossil fuel just as gas markets have grown volatile. A state study meant to justify the project was found to contain a math error that had overstated the benefits by over a billion dollars. Meanwhile, Kauaʻi's separate, smaller utility has shown that heavy investment in solar and batteries can lower costs without gas, and expects to go fossil-fuel-free by 2033. State regulators have been asked to study Oʻahu's options and report back by year's end, before any final decision on the gas project.
Ohio Power Siting Board asks court to punt on high-stakes solar case
This is a case about large-scale solar development in Ohio, not a home rooftop program, but it shows how tangled the state's approval process has become for renewable energy projects. In 2022, the Ohio Power Siting Board denied a permit for Kingwood Solar, a 175-megawatt solar farm, mainly because local township and county boards opposed it, even though the project met every other legal requirement. The developer appealed, and the case has sat before the Ohio Supreme Court for years. Now the board wants the case dismissed entirely, arguing that Kingwood Solar's grid connection agreement expired while everyone waited, making the whole fight pointless. Solar advocates say that's unfair, since the board itself missed deadlines that helped cause the delay, and the court then took years to rule. They argue a decision on the merits would clarify how much weight local opposition should carry when the state decides whether a renewable energy project serves the "public interest" — a standard the board has applied inconsistently since a 2021 state law added extra hurdles, including letting counties block projects before they even reach state regulators. For homeowners, this doesn't affect any rebate or upgrade program directly. But it matters for anyone watching Ohio's energy costs and supply, since large solar projects add power to the grid at a time of rising demand and prices. A similar case involving another solar farm is also awaiting a ruling, so this uncertainty over how Ohio treats renewable energy projects is likely to continue regardless of how the Kingwood case ends.
Sunrun’s new distributed AI data center pilot could be the start of something big
Sunrun, the residential solar and battery company, is testing a new idea: putting small AI computing devices inside homes that already have its solar panels and batteries installed. These "compute nodes" would run AI inference tasks — the everyday work of already-trained AI models answering questions or processing requests, as opposed to the heavier job of training new models. Sunrun would sell this computing capacity to businesses, and homeowners who host a node would get paid, though the company hasn't said how much or how payment might vary by location. The pitch is that homes paired with solar and battery storage are a good fit for this kind of work, since the batteries can keep a node running during a power outage, and Sunrun's software can coordinate the node's operation with a household's energy use and electricity rates. This spreads AI computing across many homes instead of concentrating it in large data centers, which avoids some of the grid strain and construction hassle those facilities require. If you already have Sunrun solar and battery equipment, this could eventually mean an option to host one of these devices for extra income, but the pilot is still in early testing and Sunrun hasn't laid out specific terms, payment amounts, or a timeline for when this might become widely available. The company says the pilot will run for the next few months, after which it will decide whether to roll the program out more broadly. Homeowners curious about it can find a waitlist sign-up on Sunrun's website.
'It Doesn't Seem Like Much Is the Same Except That It's Still HVAC'
This is an interview with Stan Johnson, a retired HVAC contractor who ran his family's Austin, Texas business from the 1970s until 2011. It's a look back at how home heating and cooling has changed over 60-plus years, not a report on a new program or product. Still, it's a useful reminder of how far the technology behind your own system has come. Johnson recalls when homes relied on swamp coolers and window units, when sizing an air conditioner meant a rough rule of thumb (500 square feet per ton) rather than the room-by-room load calculation contractors use today. As homes got better insulation and double-pane windows in the 1970s-90s, old sizing habits stopped working and led to humidity problems, pushing the industry toward proper load calculations and duct sizing standards. Controls evolved too, from mechanical timers to circuit boards that sense pressure and adjust output automatically, the basis for today's variable-speed heat pumps. For homeowners, the takeaway is really about context: modern heat pumps and controls exist because the industry spent decades fixing sizing and installation mistakes that caused uneven temperatures and humidity problems in houses. Johnson also notes that contractor licensing and technical standards raised wages and professionalism in a field that used to be an afterthought for plumbers. There's no specific rebate, deadline, or program news here, just a veteran's perspective on how the equipment in your walls and attic got to where it is now.
Everyday Stories, Capitol Hill Impact: Trusted Messengers Take D.C.
A group called Generation180, working with two other clean energy organizations, brought local leaders to Washington, D.C. on June 23 to talk with congressional staff about clean energy in their communities. The group included a mayor from Enfield, North Carolina, a town that has built a community solar farm and a rural geothermal network (which uses underground pipes to share heating and cooling among nearby buildings), and a community leader from Savannah, Georgia, who has helped neighbors prepare for hurricanes and power outages. They met with staff from senators and representatives in Georgia, North Carolina, and Pennsylvania. The message to Congress centered on affordability: lower energy bills, local jobs, and communities that can keep functioning when the grid goes down. The visitors also raised concerns about recent rollbacks to clean energy policy, saying they risk jobs, stall local projects, and push costs back onto families. They argued that as data centers put growing strain on the electric grid, investments in energy efficiency, resilience, and grid upgrades matter more, not less. For homeowners, this isn't a new program or rebate. It is a snapshot of the advocacy happening in Washington around whether federal support for local clean energy and efficiency work continues or shrinks, decisions that can eventually shape what incentives and grid programs are available where you live.
PJM status quo ‘untenable’: FERC Commissioner LaCerte
A federal energy regulator says the way the country's largest grid operator, PJM, makes decisions is not working. David LaCerte, a commissioner at the Federal Energy Regulatory Commission (FERC), said PJM's process for gathering input from utilities and other players has "ground into gridlock," calling the current setup untenable. PJM runs the electric grid and wholesale power markets across 13 mid-Atlantic and Midwestern states plus Washington, D.C., so decisions made there ripple into the rates and reliability of homes in that region. FERC plans a hearing on July 23 to look at possible fixes, including faster review procedures for urgent issues. Separately, FERC is reconsidering the financial incentives it gives companies to build new power lines, such as extra profit margins and the ability to recover construction costs early. LaCerte said these incentives haven't been revisited in years in some cases and need to be tied more closely to actual results, like lower costs for customers. He also said FERC will keep looking at newer grid technologies that can move more power through existing lines without building new ones, which can be a cheaper way to handle rising electricity demand. None of this changes anything about your home right now. It's a look at how the rules behind your electric bill and grid reliability get made, and a sign that regulators think the current system needs an overhaul. Any changes that come out of the July hearing could eventually affect electricity costs and reliability in PJM's footprint, but there's no immediate action for homeowners to take.
New York end of legislative session review
New York's legislature wrapped up its 2026 session in early June, and most of the building-related bills lawmakers considered did not pass. That means for now, nothing changes for homeowners around green building tax credits, embodied-carbon rules for new construction, or state purchasing requirements — those all stayed as proposals. A few bills worth knowing about even though they stalled: one would have made residential buildings eligible for an existing green building tax credit (currently it seems to apply elsewhere). Another would have created a tax break for green infrastructure, like rain gardens or permeable pavement, on certain properties in New York's largest cities. A third would have had the state health department set up indoor air quality inspections for schools and day cares. None of these passed this session, but lawmakers are expected to bring similar ideas back in 2027. The one bill that did move forward has nothing to do with home upgrades directly — it's a proposed one-year pause on permits for large data centers (20 megawatts or bigger), aimed at studying their effects on energy prices, the power grid, and water use. That passed the legislature and now awaits the governor's signature. If it becomes law, it could shape how much strain new data centers put on New York's electric grid in the coming years, which affects overall energy costs and reliability, though it doesn't create any new program or rebate for homeowners themselves.
Hyundai launches affordable EV deals with 0% APR and up to $10,000 off
Hyundai has kicked off a summer sales event running through August 3, offering 0% APR financing on select models, up to $10,000 in cash bonuses, and flexible lease terms. The biggest discounts go to its electric vehicles: up to $10,000 off the IONIQ 9 SUV and up to $7,000 off the IONIQ 5. Both also qualify for 0% financing for up to 72 months, extra cash off, and no payments for 90 days. For homeowners weighing an EV purchase alongside other electrification plans, the lease numbers stand out. The IONIQ 5 SE RWD, with an EPA-estimated range of 318 miles, leases for $279 a month (24-month term, $3,999 due at signing) — only $10 more than the shorter-range base model. The three-row IONIQ 9 starts at $369 a month, which Hyundai says is cheaper than comparable leases on the Kia EV9 and Hyundai's own Palisade Hybrid. By comparison, Hyundai says leases on the Tesla Model Y, Chevy Equinox EV, and Toyota bZ all run higher per month right now. This comes after the federal EV tax credit expired at the end of September, prompting Hyundai to already cut prices on the IONIQ 5 by as much as $9,800 on some trims. Both the IONIQ 5 and IONIQ 9 are built at Hyundai's plant near Savannah, Georgia. If you're considering an EV purchase to pair with home charging or other efficiency upgrades, these discounts and low lease rates are worth comparing against what else is available before the promotion ends.
The United States produced more crude oil than any other country in 2025
The U.S. pumped more crude oil in 2025 than any other country, keeping a lead it's held since 2018. Production averaged a record 13.6 million barrels a day, up from the previous record of 13.2 million set in 2024, and about 40% higher than Russia or Saudi Arabia, the next two largest producers. Much of the growth came from the Permian Basin in Texas and New Mexico, which now accounts for roughly half of all U.S. oil output. Drillers kept increasing production even as oil prices fell, thanks to efficiency gains that let them pull more oil from each well. Russia's output stayed flat, held back by production cuts and the ongoing conflict with Ukraine. Saudi Arabia's production rose modestly as the OPEC+ group of oil-exporting countries eased its own voluntary cuts. Forecasts point to U.S. production holding near 13.7 million barrels a day in 2026, then climbing to 14.2 million in 2027, with oil prices expected to rise as well. For homeowners, this is mostly background context rather than something that changes your bills or plans directly. Higher U.S. oil production has helped keep gasoline and, indirectly, some energy costs in check, but it does not affect electricity rates or home heating fuel in a direct way tied to any specific program or rebate. The bigger story here is about America's role in global energy supply, not a change you need to act on at home.
Republicans & Democrats in Congress Unite in Effort to Ban Chinese Electric Vehicles
The Senate Commerce Committee is set to vote on July 15 on a bipartisan bill that would block Chinese automakers from selling electric cars in the United States. The bill, proposed by Republican Senator Bernie Moreno of Ohio and Democratic Senator Elissa Slotkin of Michigan, would write into law a rule the Biden administration already put in place effectively banning Chinese passenger vehicles from the US market. Similar legislation has been introduced in the House. The stated reason is national security: officials argue that cars with advanced connectivity and software built in China could collect sensitive data on American drivers. This would come on top of 100% tariffs already placed on Chinese EVs. Auto trade groups representing nearly all major carmakers, including the Detroit automakers, Volkswagen, Hyundai, and Toyota, have pushed for this restriction, citing concerns about China's dominance in vehicle manufacturing. For homeowners, this is mostly background news rather than something requiring immediate action. Chinese-brand EVs are not being sold in the US market currently, so this legislation would not change what is available in dealerships right now. If you are weighing an EV purchase alongside other home energy upgrades, like a heat pump or home charger, your practical options will continue to be vehicles from US, European, Japanese, and Korean automakers already sold here. Whether this bill passes or not, it does not change the rebates or incentives available for home energy equipment.
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.
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.
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.
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.
