There she goes again. In recent years, General Motors Chair and CEO Mary Barra has shaped the automaker into a renewable energy influencer with an impact on the US energy landscape that extends beyond the factory walls. Apparently she was just getting started. The company has just announced a new carbon-cutting initiative that sets a 100% renewable energy goal by 2025. Yes, 2025. Not 2035, or even 2030. It’s 2025 or bust.

Coming from one of the top industrial employers in the US, the announcement validates President Biden’s ambitious climate goals even as Republicans in Congress continue to hit the kill switch on climate action.

GM Hearts Renewable Energy For Everybody

Barra doesn’t get nearly as much publicity as some other auto industry execs, so before we get into her latest renewable energy plan, let’s take a quick look back at the renewable energy theme she has established for GM.

The basic premise is pretty simple. Rather than focusing on renewable energy projects that only benefit the company’s carbon profile, GM is part of a broader corporate movement to spur renewable energy investments that provide whole-of-economy benefits and influence consumer behavior. Cutting costs for everyone while increasing access and improving reliability across the grid are the end goals.

In 2016 GM joined the global RE100 clean power collaborative and another big step occurred in 2019, when the company became a founding member of the Renewable Energy Buyers Alliance, a US organization that leverages corporate purchasing power to accelerate economy-wide decarbonization.

The initial REBA goal was 60 gigawatts of new renewables by 2025. GM helped get the ball rolling in 2019 by putting in for the equivalent of 300,000 megawatt-hours in new wind energy through the Michigan utility DTE.

In a convo with CleanTechnica that year, Rob Threlkeld, GM’s global manager of Sustainable Energy and Supply Reliability, explained that the DTE deal reflects the tandem transformation of both the auto industry and the utility industry, and the adaptation of consumers to the new energy landscape.

Renewable Energy & Consumer Behavior

When the topic turns to the auto industry, the new energy landscape, and consumer behavior, attention naturally turns to electric vehicle charging.

GM had EV charging and consumer behavior on the top of its mind when it introduced the Chevy Volt gas-electric hybrid in 2010. The Volt enabled car buyers to dip a toe in the 100% EV experience while clinging to the safety net of a gas tank at a time when battery technology was limited and charging stations were relatively scarce.

More recently GM has begun pivoting to a 100% EV future, and that doesn’t just mean selling the cars. Providing consumers with access to both charging stations and renewable energy is a key part of GM’s plan.

In 2020, for example, GM announced a new 500,000 megawatt-hour solar energy commitment through DTE, and it hooked up with the company EVgo to install more than 2,700 public fast charging stations around the country. Earlier this year GM also inked a deal to splash digital EV advertising all over Volta charging stations in key markets, aimed at reaching 70 million potential car buyers.

More Renewable Energy For The Clean Car Of The Future

GM’s triple-whammy approach of electric cars, renewable energy, and charging stations is getting picked up by utilities that are eager to sell more kilowatts. The gigantic utility Xcel Energy, for example, has just established a new incentive program to encourage its ratepayers to buy more electric vehicles.

The problem is that Excel’s stable of power plants still runs on a heavy dose of fossil energy, and that’s where the new GM renewable energy initiative comes in.

Today’s 100% clean power announcement by GM includes a partnership with the carbon tracking and energy management firm TimberRock. The idea is to leverage energy storage and variable demand to squeeze the maximum amount of renewable energy available on the grid for GM facilities.

In addition, GM expects to expand the carbon tracking feature to its electric vehicles. That will enable the company to prioritize its renewable energy purchasing activity for maximum impact on EV charging.

EV carbon tracking is a key new element in the climate action game, because Xcel is not alone. The US grid is still very much in a transitional period, with a heavy reliance on natural gas and coal for power generation. The very success of the EV revolution could bog down decarbonization goals in a sea of juiced-up demand for kilowatts as millions of EVs hit the road and plug into charging stations.

If all goes according to plan, the TimberRock partnership will help dampen the impact of EV sales on power plant emissions by enabling GM to target its power purchases strategically, in order to help ensure that EV battery charging takes maximum advantage of renewables on the grid.

GM’s work with TimberRock dates back to 2011, when the two companies paired to build a lone solar-powered EV charging station at General Motors’ Allison Transmission Plant in Maryland. The new carbon tracking partnership takes that relationship into next-level decarbonization territory.

GM Comes Out Swinging For Renewables

As for the timing of the announcement, it follows on the heels of a salvo that GM fired off on Tuesday, apparently aimed at Republican obstructionists in Congress and the two Democratic holdouts against President Biden’s climate action plans.

“General Motors applauds those who have worked tirelessly to advance the Build Back Better Plan, including the Bipartisan Infrastructure Framework, and urges Congress and the Administration to move forward legislation that will bring critical improvements to the country,” GM wrote.

GM also gently reminded legislators that the end goal of decarbonization is to fend off catastrophic climate change.

“General Motors believes we can help create a world that is safe and sustainable, where future generations can thrive,” the company wrote, while taking note of its plans to “achieve a clean and equitable transition to an all-electric future.”

“But we can’t do it alone,” GM warned, underscoring the need for strong federal action.

Placing itself firmly in the camp of President Biden, the company concluded that “General Motors looks forward to joining the President, Congress and the American people in celebrating enactment of legislation that creates a pro-growth, pro-jobs and pro-sustainability future.”

Whelp, Here’s To Going It Alone

In another interesting bit of auto industry timing, earlier this week Ford also unleashed a massive, history making new EV manufacturing and workforce training announcement that supports the President’s plan for rapid decarbonization and new green jobs. The Ford announcement includes a vast new carbon neutral campus in Tennessee, powered partly with local renewable energy.

Together, the GM and Ford announcements put more pressure on legislators to act.

That could be too little, too late. Democrats in the House of Representatives have a sufficient majority to pass legislation, but the Senate is a different story.

The likelihood of getting enough Republican Senators on board to break a filibuster is unicorn-level small. Democrats could still manage to make some progress by exercising their slim 51-vote majority through the reconciliation process, except as of this writing they can only count on 49 votes.

For those of you not following the news, the two Democratic holdouts are West Virginia Senator Joe Manchin and Arizona Senator Kyrsten Sinema.

I know, right? Well, that’s the way the Senate works. If voters in other states vote out their Republican senators and replace them with Democratic senators who support Democratic presidents, the names Manchin and Sinema would quickly fade into the dustbin of history. As things stand, they appear destined to join the climate obstruction hall of fame right alongside the usual suspects.

Meanwhile, Ford and GM seem determined to follow through on their EV and renewable energy plans no matter what Congress does, though both companies are members of the corporate organization Business Roundtable, which is reportedly lobbying against the reconciliation bill.

Go figure! If you have any thoughts about that, drop us a note in the comment thread — and stay tuned for word on Stellantis, the third member of the Big 3 legacy auto-making club.

Homeowners share surprising, real-world data after installing solar panels

Are you wondering what kind of results you’d get if you added a home solar system to your roof? Homeowners are sharing their results online — and the real-world data might surprise you!

In a recent post to r/Solar, a Reddit user going by DontBuyBitcoin shared a screenshot indicating that their newly-installed ~11.5 kW system produced over 1,700 kWh of electricity in October. “Pretty surprised by the production of the system I got,” writes DontBuyBitcoin. “11.48KW. I cant wait to see what JUNE-AUGUST [2026] going to look like 😍 I wish SolarEdge will make their app better looking with more functionality”

Other Redditors were quick to share in the enthusiasm. “Congratulations!!! Great numbers,” wrote LegalNet4337. “We got 1.6 MWh with a 14.45 kW system. East and West facing panels in SoCal.”

That 1,700 kWh is nothing to sneeze at. Based on the current national average electricity price of about $0.17/kWh (in AUG2025), DontBuyBitcoin’s admittedly large-ish system translates to ~$290 of potential savings. In a higher rate state like Illinois, with a projected 2026 kWh rate that’s closer to $0.18/kWh, that’s ~$306/mo.

We expect retail electricity prices to residential customers will average 17 cents per kilowatthour (kWh) nationwide in 2025, a 4% increase over 2024, and then rise to approximately 18 cents/kWh in 2026. This rise continues a trend in which residential electricity prices have increased at an average annual rate of 5% each year since the COVID-19 pandemic. The increase in retail electricity prices this year comes as the cost of natural gas to the electric power sector was up more than 40% in 1H25 compared with a year earlier, with similar year-over-year increases forecast for the remainder of 2025. The average cost of natural gas for power generation in our forecast increases another 17% in 2026.

US ENERGY INFORMATION ADMINISTRATION (EIA)

Those are big numbers, but 11-15 kW rooftop solar systems are big. Significantly bigger, in fact, than the US average, ~6.6 kW in 2024 – but you don’t have to have a big system in order to post big numbers. Superior weather conditions and perfect PV panel placement can also get the job done, as another Redditor found.

“The last 2 days we have had perfect weather here in South Florida and I have been able to get over 30 kWh from a 5 kW system with a 3.8 kW inverter. This is the highest I have seen since getting PTO in September,” wrote Redditor dlewis23, who shared another SolarEdge graph. “I am super happy with seeing over 30 kWh in a single day.”

30 kW/day from home solar


Taken altogether, these real-world snapshots prove that whether it’s a modest 5 kW array or a beefy 10+ kW setup, homeowners out in the real world are seeing meaningful, measurable differences from their home solar installations. And, with retail electricity prices projected to keep on rising through the decade, every kilowatt counts.

Electrek’s Take


From Electrek SEP2025 survey.

When we ran our “Why did you choose to go solar?” survey back in September, only 32.6% of respondents chose, “Lowering my monthly utility bills” as their primary motivation to go solar. That result proved, in my mind, that Electrek readers are just better people than most, and seem to be willing to spend a little more to do something positive for their environment and their community.

That said, wasn’t it no less a thinker than Albert Einstein who said, “Compound interest is the most powerful force in the universe” (Google it.)? And, with a 5% rate hike compounding every year from now until the AI and data center bubbles burst, the impact energy rates may have on all our pocketbooks may be enough to put “Lowering my monthly utility bills” back on top.

If and when that happens: be smart, get several quotes, and understand the difference between buying and leasing your PV system (especially if you plan on selling your home in the foreseeable future).

Volvo set to ditch LiDAR for 2026 – and Luminar is BIG mad

Volvo set to ditch LiDAR for 2026 – and Luminar is BIG mad

It seems like the writing was already on the wall last week when Volvo moved to make its Luminar-supplied LiDAR system an option – there are now reports that the Swedish car brand is set to ditch LiDAR tech entirely in 2026.

In a recent SEC filing following a missed interest payment on its 2L notes, Luminar confirmed that Volvo’s new ES90 and EX90 flagship models (along with the new Polestar 3) would no longer be offered with LiDAR from Luminar. The move signals a full reversal on the safety tech that had started as standard equipment, then became an option, and is now (according to reports from CarScoops) gone altogether.

In a statement, a Volvo Cars USA spokesperson added the decision was reportedly made, “to limit the company’s supply chain risk exposure, and it is a direct result of Luminar’s failure to meet its contractual obligations to Volvo Cars.”

This is what Luminar had to say about the current, icy state of the two companies’ relationship as of the 31OCT filing:

The Company’s largest customer, Volvo Cars (“Volvo”), has informed us that, beginning in April 2026, Volvo will no longer make our Iris LiDAR standard on its EX90 and ES90 vehicles (although Iris will remain an option). Volvo also informed the Company that it has deferred the decision as to whether to include LiDAR, including Halo (Luminar’s next generation LiDAR under development), in its next generation of vehicles from 2027 to 2029 at the earliest. As a result of these actions, the Company has made a claim against Volvo for significant damages and has suspended further commitments of Iris LiDAR products for Volvo pending resolution of the dispute. The Company is in discussions with Volvo concerning the dispute; however, there can be no assurance that the dispute will be resolved favorably or at all. Furthermore, there can be no guarantee that any claim or litigation against Volvo will be successful or that the Company will be able to recover damages from Volvo.

As a result of the foregoing, the Company is suspending its guidance for the fiscal year ending December 31, 2025.

LUMINAR

On November 14, Luminar confirmed that Volvo had terminated its contract altogether, in a blow that could leave Luminar rethinking its long-term future and planning litigation against its biggest ex-customer.

The news follows a host of significant upgrades to the EX90 that include a new, more dependable electronic control module (ECM) and 800V system architecture for faster charging and upgraded ADAS that improves the automatic emergency steering functions and Park Pilot assistant.

Electrek’s Take


You can’t spend years telling everyone you’re miles ahead because you have LiDAR, then ditch LiDAR, and pretend no one is going to call you out on it. They had better hope they don’t up on Mark Rober’s YouTube channel doing a Wile E. Coyote impression (above).

That said, it’ll be interesting to see if ditching the LiDAR has a negative impact there. Or, frankly, whether ditching the LiDAR and its heavy compute loads will actually help mitigate some of the EX90’s niggling software issues. It could go either way, really – and I’m not quite sure which it will be. Let us know which way you think it’ll go in the comments.

John Deere electric riding mower gets removable batteries from EGO

The new John Deere Z370RS Electric ZTrak zero turn electric riding mower promises all the power and performance Deere’s customers have come to expect from its quiet, maintenance-free electric offerings – but with an all new twist: removable batteries.

The latest residential ZT electric mower from John Deere features a 42″ AccelDeep mower deck for broad, capable cuts through up to 1.25 acres of lawn per charge, which is about what you’d expect from the current generation of battery-powered Deeres – but this is where the new Z370RS Electric ZTrak comes into its own.

Flip the lid behind the comfortably padded yellow seat and you’ll be greeted by six (6!) 56V ARC Lithium batteries from electric outdoor brand EGO. Those removable batteries can be swapped out of the Z370RS for fresh ones in seconds, getting you back to work in less time than it takes to gravity pour a tank of gas.

And, because they’re EGO batteries, they can be used in any 56V-powered EGO-brand tools and minibikes for unprecedented cross-brand interoperability. Tools and minibikes that, it should be noted, can be purchased at John Deere dealers across the country.

The upsell scripts write themselves, kids. And when you start your dialing, tell your prospective customers their new Z370RS Electric ZTrak electric mower lists for $6,499, and if you order now we can bundle it with EGO minibike for the kiddos – just in time for the holidays!

Electrek’s Take


When John Deere launched the first Z370R, Peter Johnson wrote that electrifying lawn equipment needs to be a priority, citing EPA data that showed gas-powered lawnmowers making up five percent of the total air pollution in the US (despite covering far less than 5% of the total miles driven on that gas). “Moreover,” he writes, “it takes about 800 million gallons of gasoline each year (with an additional 17 million gallons spilled) to fuel this equipment.”

It should go without saying, then, that states like California, which are banning small off-road combustion engines, have the right idea.
