Another state may legalize electric motorbikes up to 30 and 40 mph under sweeping new micromobility bill

Massachusetts lawmakers are weighing a new statewide law that would sort e-bikes, scooters, and similar rides by top speed rather than by what they're called or how they look. Under the plan, regular bikes and non-motorized kick scooters fall into a "Tier 0" group allowed on sidewalks. Vehicles that top out between 21 and 30 mph, including e-bikes, e-scooters, electric unicycles, and e-skateboards, would be "Tier 1," limited to bike lanes and barred from sidewalks. Faster machines capable of up to 40 mph, or beyond that, would be "Tier 2" and "Tier 3," and would have to ride with regular traffic instead of in bike lanes or on paths. The bill would also set some statewide rules that don't currently exist everywhere: riders would need to be at least 16 to operate powered devices, and helmets would be required for anyone on a vehicle that can go faster than 20 mph, as well as for younger riders on regular bikes. The proposal echoes Governor Maura Healey's earlier Ride Safe Act and recommendations from the state's micromobility committee. The goal is to replace the current mix of local rules, which vary from town to town, with one consistent set of statewide standards. This is still a proposal, not a done deal, so nothing has changed yet for riders in Massachusetts. But if it passes, it would mark a shift toward regulating electric bikes and motorbikes by their speed capability rather than their design, which could matter to anyone considering buying a faster e-bike or moped-style electric two-wheeler.

AI Industry Red & Yellow Flags

This one isn't really about home energy upgrades, but here's the gist in case AI's business troubles matter to you as a tech watcher. Several signs point to trouble in the AI chatbot industry. OpenAI is aiming for $100 billion a year in ad revenue but is on pace to bring in only around $2.5 billion this year, and one analysis suggests it could miss its 2030 ad target by 90 percent, with the whole industry's ad revenue capped well below what companies are counting on. Elon Musk's AI company, xAI (recently folded into SpaceX and rebranded), has reportedly struggled internally, with all eleven cofounders having left and staff describing chaos after SpaceX's stock offering. The company also built far more computing capacity than it needs and is now selling the extra capacity to competitors, including Anthropic, the maker of the rival Claude chatbot. Meanwhile, cheaper AI models coming out of China, including one called Kimi K3, are reportedly rattling U.S. AI executives, who are now asking the federal government for protection from the competition. OpenAI's CEO has responded by talking about cutting the cost of the company's premium AI products. None of this changes anything about home energy upgrades, rebates, or equipment costs. It's simply a snapshot of financial strain and competitive pressure inside the AI industry, worth knowing if you're curious about where all that tech investment and hype may be headed.

New Analysis Evaluates Major U.S. Investors’ Record on Key Climate Shareholder Votes

A new scorecard shows how the biggest U.S. investment firms vote on climate-related shareholder proposals, and it is not really about your home upgrades, but it does touch your money if you have savings in mutual funds, ETFs, or a retirement account. The Center for Active Stewardship, working with the Sierra Club, added a "Hidden Risk" scorecard to its free public database of proxy votes cast by U.S. funds. Proxy votes are how big investors weigh in on company decisions, including proposals tied to climate risk. The findings: Vanguard and BlackRock, the two largest U.S. asset managers, voted in line with the Sierra Club's climate recommendations only 0% and 1% of the time. Several dozen other institutions hit 100% alignment. Both firms' support for climate and social proposals has dropped sharply since 2021, when each backed more than 40% of such measures. Vanguard remains the largest fossil fuel investor among U.S. asset managers, with BlackRock second. The Sierra Club Foundation pulled its own investments out of BlackRock in 2025 after years of pushing for stronger climate action. This does not change any rebate, tax credit, or upgrade program for your house. But if you hold index funds or a 401(k) through one of these firms, the scorecard, available at scorecards.proxydata.org, lets you see how your fund votes on climate issues compared with others on the market.

Seriously, Who Is Buying All Those New Subaru EVs?

Subaru's electric vehicle sales have had a bumpy few months. The automaker's Solterra EV saw a strong jump in April, but sales dropped sharply in May and again in June. Two newer models, the Trailseeker and Uncharted, picked up some of the slack, and combined electric vehicle sales for Subaru are still running ahead of last year's pace overall. This comes even though the federal $7,500 tax credit for buying an EV was eliminated last year, which had been expected to slow EV sales industry-wide. Subaru has also delayed its next big electric model, a three-row SUV called the Getaway, which was expected in 2027. The company has not given a new timeline. The delay appears tied to production changes at Toyota, which builds Subaru's electric vehicles in the US and is adjusting plans for its own electric Highlander. That connection could still work in Subaru's favor, since the Highlander has gotten good early reviews, and some of that interest may carry over to the Getaway once it arrives. For homeowners weighing an EV purchase, the practical takeaway is that model availability and timelines remain in flux, and rebates or incentives can vary depending on the vehicle and your state. If you are considering an EV alongside home upgrades like a heat pump or a home EV charger, it is worth checking current state-level incentives, since the federal tax credit that once applied to EV purchases is gone.

Hyundai Motor Group Executive Chair Euisun Chung Announces Physical AI Vision at San Francisco AI Summit

Hyundai's parent company laid out a long-term plan to move beyond building cars and into what it calls "physical AI" — using artificial intelligence to run robots, factories, and eventually entire city systems like energy and transportation together. The company pointed to its Boston Dynamics robots, including the humanoid Atlas and the four-legged Spot, as examples of where this is headed, along with partnerships with NVIDIA, Waymo, and Google DeepMind on self-driving cars and robotics. For homeowners, this is mostly corporate strategy news with no direct bearing on your house right now. There's no new rebate, appliance, or program mentioned here — the announcement is about Hyundai's robotics and AI ambitions, plus billions of dollars in manufacturing investment in South Korea, and a robot production facility planned in the U.S. with capacity for up to 30,000 units a year by 2028. The one thread with any tie to home energy is indirect: Hyundai says it wants AI to eventually help manage "energy, mobility and robotics systems" together at a city level, part of its investment in something it calls Saemangeum AI Valley in Korea, which includes AI data centers and hydrogen infrastructure. That's a future-looking, overseas industrial project, not something that affects rebates, incentives, or upgrades available to U.S. homeowners today.

Land Rover’s fancy Freelander 8 EREV reveals high-tech, ultra-luxe interior

This one is about a car, not a home upgrade, but here's the gist. Land Rover has shown off the interior of its new Freelander 8, a luxury SUV built for the Chinese market with Chery. Photos posted on Chinese social media show a six-seat cabin with reclining "zero gravity" second-row seats that heat, cool, and massage, plus a ceiling-mounted entertainment screen, a 46.3-inch dashboard display, a 15.6-inch touchscreen, and crystal-style knobs meant to echo luxury-watch design. Under the styling, the Freelander 8 is what's called an EREV, a plug-in vehicle with a gas engine that recharges the battery once it runs low, extending range beyond what the battery alone provides. Land Rover says it gets more than 135 miles of electric-only range on the Chinese test cycle from a 60.3 kWh battery, with the gas range extender adding more distance after that. None of this affects home energy upgrades or rebates, so there's nothing for a homeowner to act on here. It's simply a look at how one automaker is blending plug-in electric range with a gas backup engine and heavy luxury features for a specific overseas market.

Loganair Agrees To Buy Five BETA Technologies Short Range Electric Aircraft

This one is about airplanes, not home upgrades, but here is the gist. Scotland's regional airline Loganair has agreed to buy five electric aircraft from BETA Technologies, with an option for five more. The planes, called the ALIA CX300, use regular runways and can recharge in 20 to 40 minutes. Test flights this year covered routes connecting Glasgow, Dundee, Aberdeen, Inverness, Wick, and Kirkwall, including Royal Mail delivery runs to remote island communities. Loganair expects the electric planes to cut operating costs by 80 percent compared to conventional aircraft, though that estimate still needs to be confirmed once the planes enter regular service. Passenger and cargo flights are planned to start in 2029, once the aircraft are certified. Separately, Airbus announced it is moving ahead with a project called LEIA, aimed at developing hybrid-electric power systems for future short- and medium-range commercial aircraft. The work will shift to a lab in Germany for testing of batteries and energy management systems, with a demonstration planned by 2027. None of this changes anything about home energy upgrades or rebates. It is simply a sign that electric power is starting to move beyond cars and into other forms of transportation, including regional flights.

Europe’s next-generation submarines are getting a lithium-ion battery upgrade

European defense contractor Saft is building lithium-ion battery systems for a new generation of naval submarines, replacing the lead-acid batteries that have powered subs since the Cold War. Naval Group plans to install these packs in Barracuda and Scorpene class nuclear submarines. This is military news, not a home energy story, but the technology involved is the same lithium-ion chemistry used in electric cars and home battery systems, just built for a very different job. Submarines use battery banks to store electricity for moments when they need to run quietly, respond fast to changing power demands, or keep life support going if the reactor shuts down. Lead-acid batteries work but take up a lot of space. Lithium-ion packs hold more energy in less room, charge faster, and let the sub run longer on stored power alone, which also frees up interior space on the ship. For homeowners, the practical takeaway is really just background: lithium-ion battery technology keeps improving and expanding into new uses, from cars to home backup batteries to now submarines. The push for smaller, denser, faster-charging batteries in defense and auto markets tends to spill over into consumer products over time, including the home battery systems paired with solar panels. Nothing here changes any rebate, program, or purchase decision for your house today, but it is a sign the underlying battery technology continues to mature.

Volvo Electric Heavy Trucks — Built in Queensland for Australia

Volvo has built its first electric heavy trucks in Australia, at its long-running factory in Wacol, Queensland. The trucks have a range of about 300 km and are meant for city and metro delivery routes, not long-haul trips across the country. Trucking company Linfox has ordered 30 of them to add to its existing diesel fleet, backed partly by government funding meant to help close the price gap between diesel trucks and electric ones. This is mostly industrial and manufacturing news rather than something that changes what's available to homeowners directly. But it points to where freight transport is headed: Volvo says a next-generation electric truck lineup with a range of up to 470 km has already launched, and a 700 km version is out in Europe, with local production of the newer trucks possibly starting in about a year and a half. Battery cells come from Samsung, with packs assembled in Europe and shipped to Australia along with other components. For homeowners, the direct impact is minimal — this is about delivery trucks, not home energy equipment or rebates. But it's a sign that electric transport is expanding beyond passenger cars into freight, which may eventually mean quieter, lower-emission delivery vehicles on local roads. Rising diesel costs are also pushing trucking companies toward electric options, alongside other new entrants like electric trucks from China and reconditioned diesel-to-electric conversions already appearing in the Australian market.

Tesla: $1.1 Billion Negative Free Cash Flow — Betting the Company’s Survival Again?

Tesla just posted negative free cash flow of $1.1 billion for the quarter, a bigger cash burn than analysts expected. Free cash flow is the money left over after a company pays for its operations and equipment, and it's a number Elon Musk has long pointed to as the real measure of whether Tesla is healthy. The shortfall came largely from $5.8 billion in spending on equipment and facilities, more than double what Tesla spent the previous quarter. Musk says that spending will pay off later. Tesla still reported $1.1 billion in net profit and record revenue for the quarter, so the company is not in trouble right now, and it has a large cash reserve to draw on. But average selling prices fell, and Tesla got less revenue from regulatory credits, a source of income it has relied on heavily in the past. For a homeowner, this isn't directly about your house or an upgrade you're planning. It matters mainly if you're weighing a Tesla purchase, hold Tesla stock, or are curious about the company's direction, including its self-driving Robotaxi service and its business in China, where competition has gotten tougher. The bigger financial picture is mixed: Tesla has plenty of cash on hand, but its profit margins have been sliding for a while, and this heavy new spending adds a question mark. There's no news here about EV tax credits, charging incentives, or anything tied to home energy upgrades or rebates.

Waymo is 2/3 safer than a human driver, says IIHS – with some caveats

This is a road-safety story rather than a home-energy one, but here's the gist. The Insurance Institute for Highway Safety looked at federal crash data from 2021-2024 and found that Waymo's self-driving taxis got into 68% fewer crashes serious enough to report to police, compared with the average human driver, over 50 million miles of autonomous driving. Waymo's crashes also tended to be less severe. The pattern held in three of the four cities studied — Phoenix, San Francisco, and Los Angeles — though Waymo had a slightly higher crash rate than humans in Austin, likely because so few miles had been logged there. The study has real limits. Waymo avoids highways and drives more often on slow city streets, which can make its numbers look better than a fair side-by-side comparison would. Nearly half its miles carried no passenger, so there was no one inside to get hurt, which also lowers its injury count. And the overall sample size, while large for a robotaxi study, is tiny next to the roughly 222 billion human miles driven in those same areas, so some crash categories only have a handful of incidents recorded. None of this changes anything about your house or your utility bills — it's simply an update on how self-driving cars are doing on safety, with real numbers but real caveats attached.

Domestic Hot Water (DHW) and Legionnaire’s Disease

A homeowner forum post on Green Building Advisor points to a real concern for anyone with a hot water system: Legionnaire's disease, a lung infection caused by legionella bacteria that can grow in household plumbing. The bacteria thrive in certain conditions inside water heaters and pipes, and one factor called out is "dead legs" — sections of plumbing that sit unused for long stretches, like a line running to a guest bathroom that rarely gets turned on. The post references the Centers for Disease Control and Prevention's guidance on controlling legionella in building water systems, which lays out the conditions that let the bacteria grow and design choices that help prevent it. This matters as more homes move toward heat pump water heaters and other efficiency upgrades, since some of these systems run at lower storage temperatures than traditional tank heaters, and lower temperatures can make bacteria growth more likely if water sits stagnant. There's no specific product recall or new rule here, just a reminder that hot water systems need occasional use throughout the house, not just in frequently used bathrooms and kitchens. If you have a guest bathroom, basement sink, or any other fixture that goes weeks without running hot water, it's worth knowing that stagnant lines are one of the conditions the CDC flags as worth paying attention to when thinking about home water safety.

Post–Hurricane Helene, this community is getting creative with solar

In Asheville, North Carolina, a low-income, mostly immigrant neighborhood called Emma is turning to solar power after Hurricane Helene knocked out the city's electricity and water for weeks. A community group called Poder Emma just added a 46-kilowatt solar array (about 100 panels) to the roof of its cultural center, which will lower the group's electric bills. The panels were donated by a disaster-relief nonprofit, installed by a local solar company, and backed by a bridge loan to cover costs until federal rebates come through. Since a full battery backup system was too expensive, the group built a cheaper workaround: a trailer with solar panels and a small battery that can plug into the community center to run the internet, refrigeration, and the pump for a well drilled after the storm. The same trailer doubles as a portable power source for a home-repair crew's tools, so they don't overload the fuse boxes in the older homes they're fixing. The group is also testing ways to bring solar to mobile homes, which are common in the area but usually too structurally weak to hold panels. Their fix: build a custom porch onto the home and mount panels on its roof. One household already has this setup, paired with a battery, at no cost to the homeowner, thanks to donated equipment and a regional solar company's assistance program. If it gets more funding, the company hopes to build more of these solar porches for other homes in the area.

A New Leadership Program for HVACR Business Owners

This news is about the heating and cooling trade itself, not a product or rebate for homeowners. The industry group ACCA (Air Conditioning Contractors of America) has started a new year-long training program called Legacy Builders, aimed at owners of HVAC companies. The goal is to help contractors who run their own businesses shift from working "in" the business day to day toward running it as a CEO, with an eye toward eventually growing the company or selling it. Enrollment is open through August 15, and the program starts this fall. The program is open only to members of ACCA and a related trade group, PHCC (Plumbing-Heating-Cooling Contractors—National Association), and it's built for companies with annual revenue roughly between $1 million and $15 million. It includes in-person workshops, monthly online sessions, mentoring from other owners, and a peer group, ending with each owner having a leadership transition plan and a plan for eventually stepping back from or selling the business. For a homeowner, this doesn't change any rebate, tax credit, or equipment option. It's a sign that the contractors who install and service furnaces, air conditioners, and heat pumps are getting more formal business training, which over time could mean more professionally run local HVAC companies. But there's no direct action or benefit here for your own house.

Maine solar customers lose electric bill credits after project developers miss state payments

About 1,800 Maine households enrolled in community solar have lost their monthly bill credits after the companies running their solar projects failed to pay a state-required fee. Community solar lets people get credits on their electric bill for power generated by a shared solar project, rather than panels on their own roof. When the project owners missed payments tied to this program, utilities Central Maine Power and Versant Power stopped passing along the credits to affected customers, who are now being billed full price for their electricity. The missed payments trace back to a Maine law, L.D. 1777, which added new capacity-based fees on solar project sponsors to help cover administrative costs and grid expenses linked to the state's Net Energy Billing program. The fees came after Maine's community solar market grew quickly enough to strain local power grids, prompting the state to adjust how costs are shared. Some project developers have pushed back hard: eleven solar companies have sued the Maine Public Utilities Commission in federal court, arguing that applying these charges retroactively is unconstitutional and hurts their projects' finances. For now, state regulators and Maine's Office of the Public Advocate are monitoring which project sponsors still owe money. Once a sponsor pays what it owes, utilities are expected to restore the missing credits and apply them retroactively to affected customers' bills. If you subscribe to a community solar project in Maine and have noticed missing credits, this dispute is the likely cause, and a resolution depends on your project's sponsor settling up with the state.

Exterior Insulation Window Detail

This one's a forum discussion, not really news, but it touches on a detail that matters if you're ever adding rigid foam insulation to the outside of your house: what happens at the windows. A homeowner wrapping his timber-frame house in two layers of 2-inch polyiso foam board (a rigid insulation panel) ran into a common problem. He'd left a gap below his windows, unsealed, so that any water getting past the window could drain out. But pressing the foam right up against the window would block that escape route. Other forum members pointed out something more basic first: there was no sill pan visible in his photos. A sill pan is a waterproof liner installed under a window before it's set in place, meant to catch any water that leaks in and direct it back outside. Codes and standard practice call for one. The suggested fix was to swap a strip of mineral wool board (a water-permeable insulation product, sold under names like Rockwool Comfortboard) in place of the foam near the window sill. Because mineral wool lets water drain through it rather than blocking it, it preserves an escape path for moisture while still insulating that area. The recommendation also included running flashing tape over the foam below and tying it into the tape coming down from the sill pan, so any water has a defined route out. For a homeowner, the takeaway is narrow: if you're adding exterior insulation to your own house, the window sill area needs special handling so water can still get out.

Renewables Provide More Than 30% of US Electricity

New federal data show renewable energy sources supplied more than 30% of U.S. electricity in the first five months of 2026, up from 28.2% a year earlier. Solar led the growth: large solar farms produced 21.6% more power than the year before, and small rooftop-scale solar systems (under 1 megawatt) grew 12.8%. Wind and hydropower also grew, while coal generation fell nearly 11% and nuclear and natural gas grew only slightly. Combined, wind and solar produced more electricity than either coal or nuclear plants during this stretch, and in May alone, solar output topped both coal and wind. Looking ahead, the U.S. Energy Information Administration expects solar, wind, and battery storage to keep expanding fast, adding roughly 83,000 megawatts of new capacity by spring 2027, while fossil fuel and nuclear capacity shrinks slightly. Battery storage, which helps store solar and wind power for use when the sun isn't shining or wind isn't blowing, is projected to grow nearly 48% over the same period. Rooftop solar's capacity is also expected to keep climbing, and researchers project that combined renewable capacity could surpass natural gas capacity by around June 2027. None of this changes any specific rebate or incentive available to homeowners right now, but it does show the broader shift underway in how the country's electricity is generated. If you're weighing a solar or battery storage upgrade for your own home, this trend suggests the technology and market around it continue to grow quickly, with more capacity coming online each year.

The Pretty Good House Blog: Choosing Healthy Interior Finishes

If you're planning a repaint or renovation, it's worth knowing what's actually in the products you bring into your home. VOCs, or volatile organic compounds, are chemicals that evaporate easily into the air at room temperature. Once airborne, they can react to form smog outdoors or, indoors, cause direct health effects through breathing, eating, or skin contact. The exact cutoff for calling something a VOC is a regulatory line, not a hard scientific one, and it varies by state and by regulator. Not all VOCs come from obvious sources. Even natural scents, like the smell of an orange peel or raw pine, are VOCs and can bother sensitive people. One builder found a client with multiple chemical sensitivity reacted badly to the terpenes in unfinished pine, even though it's a smell most people find pleasant. The general rule is that repeated, prolonged exposure raises health risk, and sensitivity to these compounds tends to build with more exposure, not less. Paint is worth special attention because of how much surface area it covers in a typical house, but it's far from the only source. Furniture, carpet, and cleaning products can all give off VOCs too, and it's often the ones with strong smells that are the biggest concern. Choosing low-VOC labeled products is a reasonable starting point when picking interior finishes, though label claims don't tell the whole story about what a material is made of or how it might affect indoor air over time.

Solar generated more electricity than coal and wind in May – EIA data

New federal energy data shows solar had a milestone month. In May, solar panels across the country (both large utility-scale installations and the smaller rooftop kind) generated more electricity than either coal or wind. Solar produced 47,147 gigawatt-hours, edging out coal's 45,119 and wind's 41,157. Over the first five months of 2026, wind and solar together produced 57% more electricity than coal and 26% more than nuclear plants. The growth isn't just about output today, it's about what's being built. Over the past year, the country added nearly 28,000 megawatts of utility-scale solar capacity plus over 6,600 megawatts of small-scale solar, the kind more likely to show up on a house roof. Battery storage, which lets homes and the grid use solar power even after the sun sets, grew by over 16,500 megawatts. Federal forecasters expect solar, wind, and batteries to keep expanding faster than fossil fuels through mid-2027, while coal and nuclear capacity shrink slightly and natural gas keeps growing more slowly than renewables. None of this changes what any single homeowner needs to do right now, but it points to a broader trend: solar and battery technology keep getting cheaper and more common, and utilities are leaning into them more each year. That backdrop can matter if you're weighing whether now is a reasonable time to add solar panels or a home battery, since it suggests the industry supplying that equipment is growing, not shrinking.

FHB Podcast Segment: XPS vs. Polyiso for Continuous Insulation

A recent Fine Homebuilding podcast episode tackled a question homeowners doing exterior renovations often face: which rigid foam insulation to use on the outside of a house. A listener remodeling a 50-year-old home in North Carolina wrote in asking whether to use XPS or polyiso foam board as continuous insulation (a layer of foam that wraps the whole house to cut heat loss through the wood framing) under new siding, along with a rainscreen, which is a small air gap behind the siding that lets moisture drain and dry out. Both foam options cost about the same at the 1-inch thickness being considered, so the choice comes down to performance rather than price. The podcast hosts discussed the tradeoffs between the two foam types, since each behaves differently depending on climate and how it is installed. This kind of decision matters mainly to homeowners who are re-siding a house or adding exterior insulation as part of a larger renovation, since the type of foam chosen affects how well the wall resists moisture and keeps heat in or out over time. If you are planning a similar project, the choice of foam type is one of several details worth understanding before work begins, alongside the rainscreen approach itself, which is increasingly common in siding replacements. Local climate plays a role in which product tends to work better, so it's worth learning how these materials perform in a climate similar to your own before settling on one.

Food Retail's Next Build: Smarter Energy, Sharper Compliance

This is a promotional piece for a grocery industry conference and doesn't have direct action items for homeowners. The event, FMI's Energy & Store Development Conference, is set for September 28–30 in Orlando, and it's aimed at grocery retail executives who plan store construction and upgrades, not homeowners. The topics on the agenda are still worth knowing about, since they show where commercial building technology is headed. Grocers are grappling with refrigerant transitions, moving toward A2L and CO₂-based refrigeration systems as older refrigerants get phased out under regulation. They're also dealing with strained power grids as data centers and electrification push demand higher, and they're starting to use AI to manage store operations even though rules around it are still catching up. None of this changes what's available to homeowners in rebates or upgrade programs. It's a reminder that the same pressures reshaping home energy use, cleaner refrigerants, grid strain, smarter controls, are playing out at a larger scale in commercial buildings too. If you're curious about refrigerant changes because you have an older air conditioner or heat pump, it's a sign that similar phaseouts and equipment shifts are affecting more than just grocery store coolers.

Critical Capital: Is this infrastructure’s once-in-a-generation moment?

This is a podcast episode about big-picture infrastructure investing, not a story with direct steps for homeowners. Alfred Johnson talks with Jessica Bailey, who leads infrastructure investing at Nuveen, an investment firm managing more than $1.4 trillion in assets, including $40 billion she directs into infrastructure. The conversation covers how the energy transition, the growth of digital and AI infrastructure, and aging power grids are together driving what the two describe as an unusual moment for infrastructure spending. Bailey's background includes climate philanthropy work and early involvement in C-PACE financing, a financing tool that lets building owners pay for energy upgrades through a charge added to their property assessment rather than a traditional loan. The episode touches on the financing structures needed to expand domestic manufacturing, and makes the case that economic pressures are starting to matter more than political disagreements when it comes to infrastructure decisions. Bailey also raises a point about artificial intelligence: its growth may be limited less by available money and more by energy supply and pushback from communities near new energy or data infrastructure projects. There is no program, rebate, or deadline here that affects a specific home. It is a discussion of investment trends shaping the broader energy and infrastructure landscape, including the financing tools, like C-PACE, that eventually filter down into building upgrades. Homeowners following energy-efficiency news may find it useful background on where money and policy attention are heading, even without a direct action tied to their own house.

States can pursue 20 strategies to speed low-cost clean energy, says Energy Innovation

The think tank Energy Innovation has laid out 20 policy ideas states could adopt to speed up clean energy projects, arguing this is the cheapest way to handle rising electricity demand from data centers and other new users while keeping costs down for consumers. These policies would need to come from governors, state legislatures, or utility regulators, not from individual homeowners, but the changes could eventually affect electricity rates and how easily solar or wind projects get built near you. The recommendations cover several areas. Some states could adopt stronger clean energy targets, similar to the 28 states that already have them. Others could streamline permitting for solar and wind, since roughly a quarter of U.S. counties now have some restriction on these projects. The report also pushes utilities to use realistic, market-based cost estimates when planning future power supplies, and to hold utility profits accountable if fuel prices spike, rather than passing all the cost to customers. It favors competitive bidding for new power projects and new ways for large customers, like tech companies, to buy clean power directly from generators. On the local grid side, the report supports letting solar and wind projects connect at underused points on the grid, upgrading transmission lines with newer, higher-capacity conductors, and simplifying permitting and inspections for rooftop solar. These grid and permitting changes are the ones most likely to eventually touch homeowners, since faster, simpler rooftop solar approval could make installing panels quicker and less costly. Whether any of this becomes law depends on individual states, so what applies to your area will vary.

This week's Fine Homebuilding podcast covers a mix of building topics, including one that touches climate and materials: a Netherlands startup called New Dawn Bio says it has grown wood in a lab that develops far faster than trees in a forest, without cutting any down. The company raised $2.4 million in early funding and says the process could cut wood costs by cutting waste from sawing and gluing. It's an early-stage technology, not something available for home projects yet, but it points to where building materials may be headed as the industry looks for ways to cut deforestation and emissions. The episode also answers two listener questions relevant to anyone dealing with an older or humid house. One homeowner restoring a long-vacant Victorian house in Ontario is fighting high humidity, especially in a basement with a dirt floor. The hosts discuss whether covering the dirt with plastic sheeting (a vapor barrier) and insulating the basement walls would help dry things out, since a 50-pint dehumidifier alone hasn't gotten humidity below 60%. The second question comes from a homeowner in North Carolina replacing windows and siding on a 50-year-old house, who's deciding between two types of rigid foam board, XPS or foil-faced polyiso, for a layer of continuous insulation outside the wall sheathing. The discussion centers on whether the foil facing on polyiso could trap moisture in a humid climate, versus using a foam that lets more moisture pass through. Anyone planning a similar siding or window replacement with added exterior insulation faces the same tradeoff, and the right choice depends on climate and how the wall is built.

New solar output is still outpacing fossil fuels, nuclear

Solar power keeps growing faster than fossil fuels and nuclear power nationwide. Renewable energy sources now make up 30% of all U.S. electricity, and their output grew more than 10% in the first five months of 2026, according to a review of federal energy data by the SUN DAY Campaign. Large-scale solar farms grew about 21% compared with last year, while nuclear and natural gas combined dropped 3.8% and coal fell nearly 11%. Wind and solar together now produce 57% more electricity than coal. Over the past year, utility-scale solar added nearly 28 gigawatts of capacity, small-scale solar (the kind installed on homes and businesses) added 6.6 gigawatts, and battery storage added 16.5 gigawatts. Total renewable capacity growth was up 41% compared with the year before. If this pace holds, solar could pass natural gas in total capacity by spring 2027, and renewables overall are projected to add 83 gigawatts to the grid by May 2027, while fossil fuel and nuclear capacity shrink slightly. None of this changes anything about your own home directly, but it points to a bigger shift in where the country's electricity is coming from. As solar and battery storage keep expanding faster than coal, gas, and nuclear plants, the power mix behind your utility bill is likely to keep leaning more toward renewable sources in the coming years, regardless of what happens with federal policy.

As climate lawsuits advance, the oil industry enters ‘panic mode’

Oil companies are facing a wave of lawsuits over their role in fueling climate change, and this month a Washington state judge let one of the most striking cases move forward. The lawsuit centers on a woman who died during the 2021 Pacific Northwest heat dome, when temperatures hit 108 degrees. Her daughter sued Exxon Mobil, BP, Chevron, Shell, and others, arguing the companies knew for decades that burning fossil fuels would cause dangerous warming but hid that knowledge from the public. Nearly 40 similar lawsuits are pending nationwide, with at least five already in the evidence-gathering stage that comes before trial. In response, the oil industry and its allies have pushed hard to shut these cases down. Several states, including Utah, Iowa, Tennessee, Oklahoma, and Louisiana, have passed laws shielding fossil fuel companies from climate-related lawsuits, and Republicans in Congress have introduced bills that would grant similar immunity nationwide. The Trump administration has also intervened, directing the Justice Department to fight state climate lawsuits and even filing its own suit against Minnesota over its case. At the same time, industry-aligned groups have challenged the scientific studies linking climate change to extreme weather, even as a major new National Academies report finds that science increasingly solid. None of this changes anything about your home directly, but it is worth watching. These cases and the fight over them will shape how much responsibility oil companies bear for climate-driven disasters like extreme heat, and whether homeowners and cities can recover costs for damage tied to a warming climate.

Canadian Solar subsidiary opens 6 GW solar cell factory in Indiana

A Canadian Solar subsidiary, CS PowerTech, has started production at a new solar cell factory in Jeffersonville, Indiana. The plant makes heterojunction (HJT) bifacial solar cells, a type of high-efficiency cell that captures sunlight on both sides of the panel. This first phase is part of nearly $1 billion in planned investment at the site, and the company expects the facility to eventually support more than 1,200 manufacturing and technical jobs once it's fully running. A second phase of expansion is expected to begin before the end of the year. The cells made in Indiana will be shipped to CS PowerTech's panel assembly plant in Mesquite, Texas, giving the company a more U.S.-based supply chain for the solar panels it sells. Company leaders say this matters because rules around "domestic content" — requirements that solar equipment include a certain share of U.S.-made parts to qualify for certain incentives — are shaping how solar projects get built across North America. For homeowners, this news doesn't change any rebate or incentive program directly. But it points to more solar panels on the market made with U.S.-manufactured cells, which could matter down the road if you're comparing panels for a rooftop solar installation and want to know whether they qualify for domestic-content-based incentives. It's also a sign that solar manufacturing capacity in the U.S. is growing, which over time can affect panel availability and pricing.

FERC will impose reforms if PJM fails to adopt changes by September, chairman warns

Federal regulators are pushing PJM Interconnection, the grid operator covering 13 Mid-Atlantic and Midwest states plus Washington, D.C., to overhaul how it makes decisions. FERC Chairman Laura Swett said PJM has until the end of September to agree to reforms on its own, or the agency will impose changes itself. The dispute traces back to a 2024 spike in capacity market prices, driven partly by data center demand outpacing new power supply, which pushed some utility bills up 20% or more. If your electricity comes from a utility inside PJM's territory, this is worth watching. Regulators, state officials, and even some utilities are discussing giving states more say over PJM's decisions, making the grid operator's board more independent from industry members, and changing how disputes get resolved. Some transmission-owning utilities have reportedly floated leaving PJM altogether. The goal, according to those involved, is a system that responds faster to supply problems and is less prone to gridlock — which matters because slow decision-making has been linked to the price spikes that hit household bills. Nothing here changes your rates or rebates right now. But if PJM's governance shifts toward more state input, it could affect how future capacity costs — the charges tied to keeping enough power plants available — get set and passed through to customers in the region. It is worth checking whether your state is among those pushing for a bigger role, since the outcome could shape electricity costs in PJM states over the next year or two.

Duh, solar power doesn't work at night — but it excels during the day

The Department of Energy recently criticized solar power on social media for not producing electricity at night, pointing to a July heat wave in the mid-Atlantic when solar output dropped after sunset. That's true, but it leaves out how much solar helped during the day, when demand and heat are highest. Texas offers a clear example. During this week's heat wave, the state's grid hit record electricity demand two days in a row, topping 91 gigawatts on Wednesday. Air conditioners were running full blast, but the lights stayed on. Solar, which Texas has built a lot of in recent years, provided more electricity than natural gas for several hours on Tuesday. On Wednesday, solar supplied more than a third of all the state's electricity for a full workday, reaching over 40% at times. It also charged batteries that then set a record for battery output once the sun went down and demand stayed high. That combination of daytime solar and evening battery power helped keep the grid stable and kept prices from spiking. None of this means solar can run a power grid by itself around the clock. But it does show solar's real value during the hours it works best — which happen to be the hours when air conditioning use, and strain on the grid, is at its peak. For homeowners with solar panels or batteries, or those considering them, this is the kind of daytime performance and evening backup that matters most during heat waves.

Hyundai Motor Group Launches AllDayEnergy, Its Global V2X Service

Hyundai Motor Group has launched AllDayEnergy, a new global brand for services that let electric vehicles interact with home power systems and the electric grid, rather than just draw power from them. The lineup covers three things: smart charging (called V1G), which times charging to cheaper electricity rates or grid needs; vehicle-to-grid (V2G), which lets an EV send stored power back to the grid; and vehicle-to-home (V2H), which lets an EV's battery power a house, including as backup during an outage. The idea is that an EV becomes a kind of mobile battery for your home, charging when electricity is cheap and either powering the house or feeding the grid later. Hyundai already runs versions of this elsewhere: a V2G pilot in Jeju, South Korea, V2H backup power in the U.S. during events like wildfires, and smart charging tied to changing electricity prices in the Netherlands. The rollout starts with smart charging in the UK through the Kia App in the second half of 2026, with plans to expand to Europe, the U.S., and Korea afterward, and to add V2G and V2H over time. Services will run through the Hyundai and Kia vehicle apps. No U.S. timeline, pricing, or specific vehicle models were given yet, so homeowners interested in using an EV as home backup power or grid income should watch for further announcements as the service reaches their market.

CDP adds AI to speed emissions disclosures

This is corporate sustainability news and doesn't touch home energy upgrades directly. CDP, an organization that collects corporate greenhouse gas emissions data, has added an AI tool called "Suggested Response" to help companies fill out its annual environmental disclosure questionnaire faster. The tool scans a company's existing reports and sustainability materials, then automatically fills in matching answers on the CDP survey. In early testing with about 800 companies, the tool cut prep time by roughly 40 percent and boosted the number of companies completing the survey by about 25 percent. CDP says it plans to add more AI features to make the reporting process easier and improve data quality. The bigger context: more than 22,000 companies reported emissions data to CDP in 2025, though that's down from the year before. CDP is also going through a structural change. In early June, it sold a majority stake to the private equity firm Permira and is splitting into two organizations — a commercial company that will run its disclosure platform and a separate nonprofit that will keep developing its reporting standards. None of this changes anything about home energy costs, rebates, or upgrades. It's about how large companies track and report their carbon emissions, not about programs homeowners can use.

How Gridware’s grid monitoring sensors won over a career lineman

A company called Gridware makes small sensors that clip onto utility poles and watch for signs of trouble on power lines: vibration, sound, and changes in the electrical field. The devices are solar-powered and install in minutes with four screws. They're placed on every other pole, and because power lines connect each pole to its neighbors, the sensors can pick up a problem on the "buddy pole" in between and pinpoint where it is. That matters most for a hazard called a high-impedance fault, where a downed wire or tree branch touches something without cutting off power. Normally the utility has no way to know until the fault causes an outage or starts a fire. Gridware's sensors can catch these silent faults early. The technology got a strong endorsement from a former lineman at PG&E, the Northern California utility, who was initially skeptical after years of watching similar sensor products fail to help crews in the field. He changed his mind after seeing the sensors catch a fault that could have burned nearly 500 structures across 45,000 acres. He has since retired from PG&E and joined Gridware. PG&E has installed over 10,000 of these sensors across roughly 900 miles of its lines as part of its wildfire prevention plan for 2026 through 2028. Gridware also works with other utilities, including Xcel Energy, Con Edison, and Duquesne Light in Pittsburgh. This kind of monitoring is not something a homeowner buys directly, but it can mean faster outage response and reduced wildfire risk in areas served by utilities that adopt it.

Canadian Solar ramps HJT solar cell manufacturing in Indiana

Canadian Solar has opened the first phase of a new solar cell factory in Jeffersonville, Indiana, making it the first company to produce heterojunction technology (HJT) solar cells in the United States. HJT is a solar cell design known for higher efficiency. The cells made here will ship to the company's panel assembly plant in Mesquite, Texas, where they'll be built into finished solar panels. This first phase can produce 2.1 gigawatts of cells a year, and the company expects to reach more than 6 gigawatts annually once it's fully built out, with work on a second expansion phase starting later this year. The project is tied to roughly $1 billion in local investment and more than 1,200 jobs in Indiana. Canadian Solar is also expanding its Texas panel factory to 10 gigawatts of annual capacity. For homeowners, this matters mainly as a sign that more solar panels sold in the U.S. may soon include cells actually made domestically, rather than just assembled here from imported parts. Right now, other U.S. cell makers use different cell technologies, and any HJT panels currently sold as "made in the USA" rely on cells produced overseas. If domestic content becomes important to your rebate eligibility or purchase decision, it may be worth asking installers where a panel's cells, not just its assembly, come from as more of these panels reach the market.

Data center demand is soaring, and off-grid gas won't fix the problem

Data centers are on track to use 20% of the country's power by 2035, up from just under 6% today, according to a new industry forecast. That works out to as much as 194 gigawatts of demand — more than the power grid is expected to handle. Tech companies are trying to fill the gap with their own gas and diesel generators. Elon Musk's xAI recently bought a company that runs more than a gigawatt of portable gas turbines, building on its use of diesel generators near Memphis, which is the subject of a lawsuit alleging unpermitted pollution in nearby communities. Meta and Google are also turning to gas power for their data centers. But experts say turbine shortages and workforce limits mean even heavy use of off-grid gas won't close the gap, and forecasters still see a 19-gigawatt shortfall by 2035. This mostly plays out at the level of power grids and utility planning, not individual houses. But rising data center demand is part of why electricity costs and grid strain are becoming bigger issues nationally. Separately, the Trump administration has been rolling back federal energy-efficiency programs and incentives for switching from gas appliances to electric ones, and the Department of Energy quietly removed its online guides for cutting home power bills, like tips for finding and sealing drafts, just before a major heat wave hit. On a brighter note for home solar and clean energy generally, state lawmakers introduced far fewer bills this year aimed at blocking wind, solar, and battery projects than in 2025, and only one such restrictive bill has passed.

PG&E says it has 12.7 GW in data center pipeline as it courts smaller loads

PG&E, the utility serving much of Northern California, says it now has 12.7 gigawatts of data centers in its development pipeline, up from 5.1 gigawatts last quarter. Company executives say the swings in that number reflect stricter screening of projects, not sudden growth. Most of the data centers in the queue are smaller, drawing less than a gigawatt of power, and PG&E expects to serve 1.8 gigawatts of new data center demand by 2030. Why this matters for homeowners: PG&E's CEO said the goal is to price this new demand so it lowers bills for other customers rather than raising them, since data centers can help spread the fixed costs of the grid across more electricity sales. Whether that actually shows up in your bill depends on how regulators and the company set rates going forward. Separately, PG&E is asking state regulators for more than $16 billion in revenue as part of a rate case now under review, and it has a $73 billion, five-year spending plan for power lines and generation. The company also faces billions in wildfire liabilities from past fires, including the 2021 Dixie Fire and 2022 Mosquito Fire, and is pushing state lawmakers to strengthen California's wildfire fund. Executives warned that if lawmakers don't act, PG&E may reconsider parts of its spending plan — decisions that, over time, can affect what customers pay on their electric bills.

After canceling EVs, Honda laughably tells EV owners to buy a gas guzzler instead

Honda has discontinued the Prologue, the only electric vehicle it sold in the US, after also canceling three other planned EVs and a joint EV project with Sony. The move follows a projected loss of up to $15.7 billion tied largely to tariffs and rising competition from Chinese automakers, which Honda expects will lead to its first annual loss ever. The company is now shifting its focus to hybrids, which run partly or fully on gasoline. For current Prologue owners, Honda has started adding a note to monthly auto-finance statements suggesting they "consider a hybrid" when their lease or loan is up. Owners quoted in reporting called the suggestion unrealistic, and surveys have found that around 96% of EV owners don't want to switch back to gas once they've made the change. That pattern shows up across many similar studies over the years, suggesting satisfaction with electric driving tends to be high and durable. For a homeowner thinking about this news, the takeaway is less about Honda specifically and more about the broader market: EV owners generally report they don't want to go back to gasoline vehicles, even as some automakers pull back on EV lineups. If you're weighing a future EV purchase, charging one at home typically pairs with rooftop solar and other home energy upgrades, and it's worth checking what incentives or rebates your state currently offers for both vehicles and home charging equipment, since these programs and automaker lineups are both changing quickly.

GM, Ionate deploy smart grid transformer at Michigan plant

General Motors is installing new grid technology at its transmission plant in Romulus, Michigan, a project worth noting mainly as a sign of how the power grid around large factories is changing, rather than something that affects home upgrades directly. The company is working with Ionate, a UK-based firm, to deploy what's called a Hybrid Intelligent Transformer, or HIT. This device is meant to catch and fix power quality problems as they happen, monitoring conditions in fractions of a second while running at more than 99% efficiency. It will go into GM's roughly 900,000-square-foot Romulus plant, which builds 10-speed transmissions for the company's full-size trucks and SUVs, in the coming months. GM has put $600 million into expanding transmission production capacity at this plant since November 2025, and the smart transformer is part of managing the power that expansion requires. Ionate says grids using its technology can handle 33% more distributed energy resources (things like rooftop solar or batteries feeding into the grid), carry 25% more power without needing new poles and wires, and cut wasted power by 6%, based on the company's own modeling. The bigger context is that many grids, including in parts of the U.S., Germany, and the UK, are struggling with connection bottlenecks that delay new battery storage and energy projects. Technology like this is aimed at easing those bottlenecks at a large industrial scale. It has no direct bearing on home energy upgrades, but it reflects the kind of grid strain that can eventually shape how easily homes connect solar panels, batteries, or other equipment to local power lines.

A 1.2 GW solar farm is rising at a Texas coal site – but coal is staying

A large solar project is under construction in Texas, but it won't be replacing coal power. Panamint Capital has broken ground on Big Rooter Power, a $1.7 billion, 1.2 gigawatt solar farm at its Twin Oaks site in Robertson County, between Dallas and Houston. The company calls it the largest solar farm ever built at an existing coal site in North America. But the 310 megawatt coal-fired plant next door has no announced retirement plans and remains in operation. The solar farm will be built in two phases: a 491 megawatt section now under construction, expected online in August 2028, and a 658 megawatt section starting in December 2026, expected online in August 2029. Together they're projected to create more than 800 construction jobs and contribute over $66 million to the local economy. The site will also get battery storage, new high-voltage transmission lines, and space for data centers, alongside the coal plant. First Solar will supply about 2 million American-made solar panels for the project. This isn't a coal-to-clean-energy swap. It's an example of a utility adding solar, batteries, and grid capacity onto the same land as existing coal generation, largely to meet fast-growing electricity demand in Texas, driven in part by data centers. For a homeowner, this doesn't change anything about your own rebates or upgrades, but it's a sign of how much new demand — and new generation of all kinds, including fossil fuel — is being built to keep pace with growth on the Texas grid.

Solar is having its best summer yet in Europe

Solar had its strongest stretch yet in Europe this summer. In June, it became the European Union's single biggest source of electricity, supplying a record 25% of the region's power. Spain and Germany each got more than a third of their electricity from solar that month, and Hungary topped 45%. Five years ago, solar provided only about 10% of EU power even at its sunniest peak, so this marks a fast rise. Much of that growth traces back to 2022, when Russia's invasion of Ukraine disrupted Europe's gas supply and pushed countries to build out solar and other clean energy faster than planned. The shift has paid off in cleaner air too: carbon dioxide emissions from the EU's electricity sector dropped nearly 20% between 2020 and 2025 as solar displaced coal and natural gas. Analysts expect this trend to keep speeding up. The recent conflict involving Iran has driven fossil fuel prices higher again, and EU officials are responding by pushing harder into renewables. The bloc's energy chief recently introduced a plan aimed at doubling the EU's rate of electrification by 2040. None of this changes anything directly for a homeowner outside Europe, but it's a sign of where energy costs and technology are heading. As solar keeps getting cheaper and more common on grids overseas, it adds to the broader case for rooftop solar and electrification upgrades becoming more affordable and more common everywhere, including in the US.

Tesla Stocks Down, Tesla EV Market Share Up: What Comes Next?

Tesla's stock dropped to its lowest point since last August this week, closing at $320, after a rough earnings report from CEO Elon Musk. He noted 22,000 unsold vehicles so far this year and more than 200 crashes tied to the company's driver-assistance technology. Musk also gave an update on Robotaxi, the company's driverless ride-hailing service, saying it's expanding in Florida, Texas, and the Bay Area with a fast growth rate in miles driven. But Musk has a history of missing his own timelines for Robotaxi, and the rollout has hit bumps, including a driverless Tesla spotted going the wrong way down a one-way street in Tampa just a day after launch there. Despite the stock slide and the Robotaxi stumbles, Tesla still sells more electric vehicles than any other automaker in the US, holding just over half the market in the most recent quarter. That's down sharply from the roughly 80 percent share Tesla held back in 2019, as other automakers have chipped away at its lead. For homeowners simply trying to decide on an EV, this doesn't change much day to day. Tesla remains the dominant choice, but competition keeps growing: Rivian is expanding with a new factory in Georgia, Ford is developing a midsize electric pickup, GM continues to market its Bolt as an affordable option, and startups like Slate Auto and Telo Trucks have new models coming this year. If you're weighing an EV purchase, it's worth knowing the market has more choices than it did just a few years ago.

NHTSA denies Tesla door-release defect petition, opens new door rules

This one is about car safety rules, not home energy upgrades, but it touches Tesla owners directly. Federal regulators (NHTSA) rejected a petition asking them to investigate a defect in the hidden manual door releases on 2022 Tesla Model 3 cars, covering about 179,000 vehicles. The petition, filed by a Tesla owner after a crash where his car lost power and the electric door release stopped working, argued the manual backup release was hard to find. NHTSA said current safety standards don't actually require labeling or a specific location for manual releases, and it found only one matching complaint on record, from that same owner. At the same time, NHTSA agreed to a separate request and will start writing a brand-new federal rule requiring a clear, easy-to-use emergency door release in all vehicles, not just Teslas. That process, called rulemaking, typically takes years and would only apply to future cars, not the ones already on the road. So for now, nothing changes for people currently driving a Model 3 or other Tesla with this door design. Tesla has already redesigned door handles on some models and rolled out a fix in China, and separate federal investigations into Model 3 and Model Y door releases are still open. If you own one of these vehicles, this news doesn't come with a recall or fix, just a longer-term promise of new industry-wide rules down the road.

Ontario wildfire smoke suppresses irradiance across the Great Lakes

Wildfire smoke over Ontario cut into the sunlight reaching solar panels across the Great Lakes region and parts of the US Northeast in mid-July. From July 10-21, total sunlight (measured as GHI, or global horizontal irradiance) ran up to 10% below normal in the area, according to data from Solcast, a solar forecasting company. Most of that loss came from the smoke itself blocking sunlight, not clouds. The smoke came from a fast-growing wildfire outbreak in northern and northwestern Ontario, where more than 180 fires were burning at the worst point. Winds carried the smoke southeast across Ontario and Quebec and into the US Midwest and Northeast, giving Toronto, Chicago, Detroit and Minneapolis some of the worst air quality in the world during July 14-17, and triggering air quality alerts in more than 20 US states. Airborne particle levels near Toronto tripled their earlier-July baseline during the worst days, while areas closer to the fires saw levels roughly eight times normal. For anyone with rooftop solar in the affected region, this means panels likely produced less power than usual during that stretch, both because less sunlight got through and because smoke particles settled on panel surfaces, adding to the shading effect. That soiling buildup did not clear until rain arrived on July 18. If you have solar panels and noticed lower output in mid-July, this smoke event is the likely explanation, and production should have recovered once the rain washed the buildup away.

Kia sold 110,000 EVs in Q2, with the PV5 and new low-cost models leading the way

This is car sales news, not a home energy story, but here's what happened. Kia sold 110,000 fully electric vehicles worldwide in the second quarter of 2026, up 88% from a year earlier. Growth was strongest in South Korea and Western Europe, driven by the PV5 electric van and newer, smaller EVs like the EV2, EV4, and EV5. Kia's hybrid sales also jumped 61%, with US buyers in particular favoring hybrids like the Telluride and Seltos over full electrics. For US shoppers, the more relevant detail may be pricing and timing rather than the sales figures themselves. Kia plans to launch the all-electric EV3 SUV in the US by the end of 2026, along with a new Sportage Hybrid built at a Hyundai Motor Group plant in the US. In Europe, Kia is working to make the EV2 and EV4 more affordable as local production ramps up; the EV2 Long Range recently went on sale in Germany with about 281 miles of range, starting around $38,300, though pricing for the US market wasn't given. None of this changes home energy upgrade options directly, but it's a sign more affordable EV choices, including smaller SUVs and vans, are headed to showrooms over the next year. If you're weighing an EV purchase alongside things like a home charger or solar setup, it may be worth watching for US pricing and availability details on the EV3 and Sportage Hybrid as they get closer to launch.

Volvo trademark reveals EX50 EV name: Here’s what we know so far

This is car news, not a home energy story, so there's nothing here that touches your house or an energy upgrade decision.

EPA Will Allow SRP to Continue to Recklessly Dump Toxic Waste

The EPA has approved an application from Salt River Project (SRP) to keep operating its unlined coal ash pond at the Coronado Generating Station in Apache County, Arizona. Coal ash is the waste left over from burning coal, and it contains mercury, cadmium, chromium, and arsenic. When stored in ponds without a protective liner, it can leak into groundwater, rivers, and streams, making water unsafe to drink and posing health risks to nearby communities. The Coronado pond has reportedly violated federal safety standards, and the plant has dumped more than 16 million cubic yards of coal ash over the years. This reverses course from January 2025, when the EPA had rejected SRP's request and ordered the pond closed. Under the current administration, the agency changed direction earlier this year and has now formally approved SRP's plan, letting the utility keep using the pond while it works on further paperwork for the EPA. Environmental groups, including the Sierra Club and Earthjustice, had asked the EPA to reverse this approval and stick with its original 2025 denial. For homeowners, this news is not about a rebate or upgrade you can act on. It matters mainly if you live near the Coronado plant in Apache County or rely on water sources downstream, since the decision means the toxic waste pond will keep operating rather than being closed and cleaned up. It is a reminder that coal ash regulation, and its enforcement, can shift with changes in federal policy.

Jackery is running a member sale on portable power stations starting at $79, which could interest anyone thinking about backup power for outages, though these are portable units rather than whole-home battery systems. EGO also has a cordless electric snow shovel with a 2.5Ah battery marked down to $265, a seasonal low, useful if you're looking to replace gas-powered snow removal equipment with a battery-powered alternative. None of these deals involve rebates, home energy programs, or efficiency incentives. They're standard retail discounts, so if any of the products fit something you already needed, it's worth checking current prices before the sales end.

Tesla quietly closes its secret ~$2 billion AI hardware deal

This is Tesla corporate news, not a home energy upgrade story, but here's what happened: Tesla has closed a roughly $2 billion acquisition of an AI hardware company, disclosed only in a brief line in its latest SEC filing. Tesla has not named the company, though speculation points to a chip startup tied to its former Dojo supercomputer team. The deal was paid entirely in Tesla stock, with $1.95 billion in final value — most of it, $1.73 billion, contingent on the acquired technology hitting future performance and deployment goals. Only $222 million was booked as actual recognized value, for a patent and related technology. Notably, Tesla itself says those performance milestones are currently "improbable" to be met, meaning the company is not yet counting most of the deal's value as real. This is part of a larger pattern of Tesla issuing large amounts of stock this year to fund AI infrastructure, including chip development and data-center-related projects, while also marketing its home battery product, the Megapack, as a way to help supply power for AI computing needs. For homeowners, there is no direct program, rebate, or product change here. It is a financial and corporate disclosure story about how Tesla is funding its AI ambitions, not an update to any home energy incentive or technology you could use.

EV Charging Infrastructure Partnerships Starting to Grow In Kenya

Kenya's electric bus company BasiGo has partnered with fuel retailer Rubis Energy Kenya to build fast-charging stations along the country's major transport routes. The first station is now running at a Rubis fuel stop in Sabaki, Athi River, with three more sites planned in Meru, Nanyuki, and Nyeri later this month. Unlike a private charging network built only for buses, these stations are open to the public and can charge electric vans, trucks, cars, and other compatible vehicles. The Sabaki station uses two charging plug types, CCS2 and GB/T, both fast DC chargers rated at 100 kilowatts, which can charge a typical passenger car in under an hour. Charging costs about 48 Kenyan shillings per kilowatt-hour, and all future stations under this partnership will use the same setup and pricing. This matters for Kenya's slow-growing electric car market mainly because of timing. Kenya has few electric cars on the road so far, which makes it hard to justify standalone charging stations. But BasiGo already runs a large network of fast chargers to support its electric buses, and pairing that with Rubis's 300-plus fuel stations gives the network a built-in customer base from day one. As more of these stations open along intercity routes, it becomes easier for private electric car owners to plan longer trips without worrying about finding a place to charge, which is the kind of infrastructure gap that has held back electric car adoption in the country.

This is the new 18-in-1 electric vehicle you can build yourself

This one's a novelty rather than a home energy upgrade, but worth knowing about if you're curious about electric vehicles. A Canadian company called ENVO Drive Systems has introduced a modular electric vehicle platform, the Utility Personal Transporter, that buyers can configure into as many as 18 different vehicle types from one common base. Instead of buying a separate golf cart, utility ATV, cargo hauler, or low-speed vehicle for each job, you pick a chassis and customize the drivetrain, battery, wheels, seating, and cargo bed through an online 3D configurator, similar to building with building blocks. Depending on configuration, features can include swappable battery packs, four-wheel drive, traction control for rough terrain, over-the-air software updates, phone connectivity, solar charging readiness, and weatherproofing. Pricing is expected to run from about $8,000 to $12,000. ENVO pitches it for farms, campuses, warehouses, and similar uses, though nothing rules out personal or recreational use. Pre-orders are open now, with production starting in late fall and first deliveries expected in early 2027. This isn't tied to any home energy rebate or efficiency program, so it doesn't affect weatherization or heat pump plans. It's simply a new option in the small electric vehicle space, and one to watch if you've been wanting a utility vehicle that can change purpose over time rather than buying a new one for every task.

Germany Is Subsidizing Hydrogen Truck Purchases, Not Battery-Electric Ones

Germany is offering big purchase subsidies for hydrogen delivery trucks, and a recent funding round drew 526 applications seeking €455 million against a €220 million pool. The subsidy can cover up to 80% of a hydrogen truck's extra cost over a diesel truck, plus half the cost of hydrogen fueling stations. Battery-electric trucks, by contrast, get support mainly for charging infrastructure rather than for the vehicle purchase itself. In one example, an unsubsidized battery-electric truck costs about €300,000, while a hydrogen truck listed at €425,000 can drop to roughly €205,000 after the subsidy, making it look like the cheaper option to buy even though nothing about its running costs has changed. That matters because hydrogen trucks generally cost more to operate than battery-electric ones. Hydrogen has to be made, compressed, shipped, stored, and converted back into electricity by a fuel cell, a longer and less efficient chain than simply plugging a battery truck into the grid. A purchase subsidy is a one-time payment, but fuel, maintenance, and uptime costs add up over the truck's whole working life, and that's where hydrogen's advantage from the subsidy tends to fade. This is a policy and industry story out of Germany, not something that changes anything for home energy upgrades. It doesn't involve household appliances, contractors, or rebate programs homeowners can use. It's useful mainly as a sign of how European governments are treating hydrogen versus battery power in freight, a debate that could eventually affect vehicle costs and charging infrastructure, but not your home directly right now.
