Renewables – solar, wind, biomass, geothermal, hydropower – are now 30% of total US electrical generating capacity, according to analysis of FERC’s mid-year data.
The Federal Energy Regulatory Commission (FERC)’s latest monthly “Energy Infrastructure Update” (with data through June 30, 2024), which was reviewed by the SUN DAY Campaign, also reported that June was the 10th month in a row in which solar was the largest source of new capacity. That puts solar on track to become the US’s second-largest source of capacity – behind only natural gas – within three years.
FERC says renewables were 99% of new generating capacity in June and 91% in H1 2024. 37 “units” of solar totaling 2,192 megawatts (MW) were placed into service in June along with one unit of hydropower (34 MW). Combined, they accounted for 98.9% of all new generating capacity added during the month. Natural gas and oil provided the balance: 20 MW and 5 MW, respectively. (Generating capacity is not the same as actual generation.)
During the first half of 2024, solar and wind added 13,072 MW and 2,129 MW, respectively. Combined with 212 MW of hydropower and 3 MW of biomass, renewables were 91.2% of capacity added. The balance consisted of the 1,100 Vogtle-4 nuclear reactor in Georgia plus 369 MW of gas, 11-MW of oil, and 3-MW of “other.”
Solar was 97% of new capacity in June and 77% during H1 2024. The new solar capacity added in the first half of 2024 was more than double the solar capacity (6,446 MW) added year-over-year. Solar accounted for 77.4% of all new generation placed into service in the first half of 2024.
New wind capacity in the same period accounted for most of the balance – 12.6% – which was slightly less than that added year-over-year (2,761 MW).
In June alone, solar comprised 97.4% of all new capacity added, followed by hydropower (1.5%). Solar has now been the largest source of new generating capacity for ten months straight: September 2023 – June 2024. For seven of those 10 months, wind took second place.
Solar plus wind are now more than a one-fifth of US generating capacity. The combined capacities of just solar and wind now constitute more than 20.7% of the US’s total available installed utility-scale generating capacity.
However, a third or more of US solar capacity is in the form of small-scale (e.g., rooftop) systems that isn’t reflected in FERC’s renewables data. Including that additional solar capacity would bring the share provided by solar + wind closer to a quarter of the US’s total.
Solar’s share of US generating capacity advances it to fourth place. The latest capacity additions have brought solar’s share of total available installed utility-scale (that is, >1 MW) generating capacity up to 9%, further expanding its lead over hydropower (7.8%). Wind is currently at 11.8%. With the inclusion of biomass (1.1%) and geothermal (0.3%), renewables now claim a 30% share of total US utility-scale generating capacity.
Installed utility-scale solar has now moved into fourth place – behind natural gas (43.3%), coal (15.8%), and wind – for its share of generating capacity after having recently surpassed that of nuclear power (8%).
Solar will soon become the second largest source of US generating capacity. FERC reports that net “high probability” additions of solar between July 2024 and June 2027 total 88,526 MW – an amount almost four times the forecast net “high probability” additions for wind (23,851 MW), the second fastest growing resource.
FERC also foresees growth for hydropower (1,240 MW), geothermal (400 MW), and biomass (90 MW). There’s no new nuclear capacity in FERC’s three-year forecast, and coal, natural gas, and oil are projected to contract by 20,542 MW, 3,106 MW, and 1,629 MW, respectively.
If FERC’s current “high probability” additions materialize, by July 1, 2027, solar will account for more than one-seventh (14.8%) of the nation’s installed utility-scale generating capacity. That would be greater than either coal (13.3%) or wind (12.7%), and substantially more than either nuclear power (7.5%) or hydropower (7.4%). That means the installed capacity of utility-scale solar would move into the No. 2 spot behind natural gas (40.3%).
Meanwhile, the mix of all renewables would account for 36.3% of total available installed utility-scale generating capacity – rapidly approaching that of natural gas – with solar and wind constituting more than three-quarters of the installed renewable energy capacity.
If small-scale solar systems are taken into account, within three years, total US solar capacity is likely to approach – and very possibly surpass – 300 GW. In turn, the mix of all renewables would then exceed 40% of total installed capacity, while the share of natural gas share would drop to about 37%.
Ken Bossong, the executive director of nonprofit research and educational organization SUN DAY Campaign, said:
With each passing month, renewables – led by solar – expand their contribution to the nation’s electrical capacity.
Growing from just a fraction of one percent a decade ago, solar is now nearly a tenth of US utility-scale generating capacity and poised to reach 15% within three years.

And today, Musk made it official that he will seek greater collaboration between three of his companies: Tesla, xAI, and twitter, in the form of an investment into xAI by Tesla.
The situation is a little more complicated than that, though.
Advertisement – scroll for more content
Tesla is a public company, owned by shareholders. Musk is the largest shareholder, but only owns around 12% of the company himself.
This is a different situation than xAI, which is a private company, owned by Musk. While there are other investors, he can exercise much more direct control over the company, and doesn’t have to put big decisions up to a vote.
One of the recent decisions he made with xAI was to purchase twitter in March. You may say, “wait, I thought he bought twitter back in 2022?,” and you’d be correct. Musk purchased twitter for $44 billion in 2022, which was widely agreed to be far too high a price, and then rapidly saw the company’s valuation drop to under $10 billion.
Then, in March 2025, Musk had xAI purchase twitter in an all-stock deal, valuing twitter company at $45 billion – again, far too high of a valuation, but considering he purchased the company from himself, he could set the price at whatever he wanted.
The move was widely considered to be a bailout of twitter, and the numbers involved considered arbitrary, perhaps partially to help save face for Musk after he made one of the worst business deals of all time.
Now the two are the same entity, and it seems clear that he would like to bring Tesla into the fold, in some way or another.
Musk has already improperly used resources from Tesla, a public company, to boost xAI and twitter, his private companies. Last year, he gave up Tesla’s priority position for highly sought-after NVIDIA H100 GPUs, instead shipping those GPUs to xAI and twitter. Tesla could have used these GPUs for training its FSD/Robotaxi systems, which Musk has claimed is the most important thing to Tesla’s future, but instead graciously sent them to his other company that used them to, uh, train a bot to say Nazi stuff apparently.
xAI has also poached talent from Tesla, multiple times, showing how Musk is using Tesla as a farm team for his private company.
So it hasn’t been a secret that Musk would like to use public money to bail out his private companies, as he’s been setting the stage for for a while now.
Musk has previously “discussed” getting Tesla to invest in xAI in the past, but the idea was never made official until today, when Musk said that he will put the idea to a shareholder vote.
In response to one of his superfans asking for the the opportunity to waste money on an overvalued social media app (which would mark the third time it has been overpaid for in as many years), and the backend fueling “MechaHitler,” Musk said this:
Tesla traditionally holds its annual shareholder meeting around the middle of the year, so if it were a normal year, this shareholder vote might be imminent.
But it’s not a normal year, as just last week Tesla announced an exceptionally late shareholder meeting, pushing it back to November, the latest it has ever held the meeting.
This means that Musk will have around four months to campaign for this idea – something that he’ll perhaps have more time to do, now that he’s no longer cosplaying as a government official.
We don’t know what the structure of the deal might look like yet, but Musk has been clear in the past that he wants more shares in Tesla. After selling many of his shares in order to buy twitter, he later complained that he doesn’t feel comfortable having less than 25% of Tesla. Given that his recent xAI/twitter deal was an all-stock deal, Musk could attempt to fund any investment of Tesla into xAI via shares, giving himself more Tesla shares in exchange for the company gaining a portion of xAI. Though to get him to 25% voting shares in Tesla, that would require either an enormous valuation for xAI, a small valuation for Tesla, or purchasing a large percentage of xAI (or, perhaps, all three, given how much higher TSLA’s valuation is than xAI’s).
We may however have a hint as to how that vote will go, because the last time Musk campaigned for a clearly terrible idea, Tesla shareholders ate it up.
In mid-2024, Musk ended his yearslong absenteeism at Tesla in a flurry of activity, hoping to persuade enough shareholders to vote for his illegal $55B pay package.
So it looks like we’ve got another campaign coming up, and if last time was any indication, expect some really bad decisions along the way. It worked last time, didn’t it?
Republicans recently killed a number of home energy efficiency credits, including the rooftop solar credit. That means you only have until the end of this year to upgrade your home before republicans raise the cost of doing so by an average of ~$10,000. So if you want to go solar, get started TODAY, because these things take time and the system needs to be active before you file for the credit.

The off-highway equipment experts at Perkins and McElroy have teamed up to develop a plug-and-play battery electric power unit designed to help equipment OEMs and upfitters to seamlessly transition from diesel to battery electric power.
Designed to occupy the same space as the companies’ diesel-engined power units, Perkins dropped its new battery power unit into the similarly new McElroy TracStar 900i pipe fusion machine (specialized equipment used to join thermoplastic pipes like HDPE or polypropylene by heat-welding them end-to-end to form a continuous length pf pipe).
Perkins’ battery electric power unit replaces the company’s proprietary 134 hp, 3.6 liter 904 Series Tier V diesel engine, enabling units that are already deployed to be quickly upgraded to electric power – and helping trade allies and development partners to easily retrofit existing equipment in order to add zero-emission options to their operational fleet.
“We’re actively helping customers navigate the shift in power system requirements, with a range of advanced power systems including electric, diesel-electric and alternative fuel compatible engines,” says Jaz Gill, vice president, global sales, marketing at Perkins. “When it comes to the innovative fully integrated battery electric power unit, it can be ‘dropped in’ to a machine to replace a diesel engine. The system consists of a Perkins battery along with inverters, motors and on-board chargers – all packaged up into a compact drop-in system to support seamless transition from diesel to electric for our customers looking to make that move.”

McElroy believes that an electric, emissions-free power unit like this one will open new opportunities and applications for its customers.
“Their team has done a phenomenal job of integrating their battery electric system into our TracStar 900i,” explains McElroy President and CEO Chip McElroy. “We’re really excited to see what the market thinks about this concept.”
Development of the battery electric powered pipe fusion machine was completed in about nine months. Future Perkins-powered electric equipment running the 904 diesel (small excavators, telehandlers, pumps, and gensets) could be developed even more quickly.

British ultra-luxe brand Bentley is teasing the upcoming, first-ever all electric model that will take it into the 2030s with a new concept car inspired by the iconic 1930 “Blue Train” Speed Six coupe – and it looks fantastic!
More than any other brand, Bentley was defined by its engine. For decades, in fact, the only meaningful mechanical difference between a Rolls-Royce and a Bentley was the 6.75L twin-turbocharged V8 engine under the flying B hood ornament.
That all changed at the dawn of the twenty-first century. Rolls-Royce was acquired by BMW, while Volkswagen took the reins at Bentley, setting both brands on distinct paths. Now, without its own engine, Bentley faces the challenge of proving to discerning buyers that its cars justify a premium over its mechanical cousins at VW, Audi, and Porsche. That’s why the company is looking to it pre-Rolls merger past, all the way back to the legendary 1930 “Blue Train” Speed Six coupe.
Bentley Blue Train EXP 15 concept

“Bentley’s then-chairman Woolf Barnato had a Speed Six four-door Weymann fabric saloon by H J Mulliner, which he used to race the Blue Train in 1930,” explains Darren Day, Bentley’s Head of Interior Design. “Meanwhile, he had a unique one-of-one Speed Six coupe being built, with a body by Gurney Nutting. Even though the coupe wasn’t finished when the race took place, it’s that car (the coupe) that’s become associated with it and has since become an iconic Bentley. What we were influenced by is the idea of a three-seat car with a unique window line and super slick proportions used for grand tours.”

The EXP 15 concept car features a unique, three-door, three-passenger layout under a sweeping, dramatic roofline lifted from the 1930 tourer. “The seat can rotate and you step out, totally unflustered, not trying to clamber out of the car like you see with some supercars,” continued Day, before dropping the biggest hint yet as to who they’re building the car for. “You just get out with dignity and the Instagram shot is perfect.”
Bentley EXP 15 interior
While almost no technical specs have been revealed other than “full electric,” Bentley says its new concept’s innovative interior layout allows passengers to stretch out in comfort alongside accessible storage compartments that can house a bar, hand luggage, or even pets. The EXP 15 even offers tailgate seating for outdoor parties or suburban soccer games.
But, while the new concept is tall, Bentley hopes it manages to offer the commanding driving position and comfort of an SUV while giving off the “vibe” of a classic grand tourer – something Bentley thinks could be the next wave of the luxury car market.
“The beauty of a concept car is not just to position our new design language, but to test where the market’s going,” offers Robin Page, Bentley Director of Design. “It’s clear that SUVs are a growing segment and we understand the GT market … but the trickiest segment is the sedan because it’s changing. Some customers want a classic ‘three-box’ sedan shape, others a ‘one-box’ design, and others again something more elevated. So this was a chance for us to talk to people and get a feeling.”
As before: no specs, no range estimates, and no promises about if and nothing definitive about when the oft-promised all-electric Bentley will finally bow – but this is certain: when it does arrive, it will be big, brash, and fast.
Electrek’s Take
Now that SUVs are everywhere and in every segment, automakers are desperate to explore or open new niches, hoping to find that next “SUV-like” growth segment. As weird as the three-door, three-seat EXP 15’s interior layout is, you have to admit that it’s different. And, for a vehicle that spends 90% of its time with just one person inside it, it might be more than practical enough.
Let us know if you think Bentley has a winner, or just another concept car gimmick on its hands in the comments.
