FERC: Solar + wind made up 91% of new US power generating capacity to end of May 2025
Solar and wind accounted for almost 91% of new US electrical generating capacity added in the first five months of 2025, according to data released on August 20* by the Federal Energy Regulatory Commission (FERC).
Solar’s new generating capacity in May 2025 and YTD
In its latest monthly “Energy Infrastructure Update” report (with data through May 31, 2025) reviewed by the SUN DAY Campaign, FERC says 43 “units” of solar totaling 1,515 megawatts (MW) were placed into service in May, accounting for 58.7% of all new generating capacity added during the month.
The 11,518 MW of solar added during the first five months of 2025 was 75.3% of the total new capacity placed into service.
Solar has now been the largest source of new generating capacity added each month for 21 consecutive months, starting September 2023.
Solar + wind were nearly 91% of new capacity through May
Between January and May, new wind provided 2,379 MW of capacity additions, accounting for 15.6% of all new capacity added during the first five months of 2025.
For the first five months of 2025, solar and wind comprised 90.9% of new capacity while natural gas (1,381 MW) provided just 9.0%; the remaining 0.1% came from oil (14 MW).
Solar + wind are 22.9% of US utility-scale generating capacity
The installed capacities of solar (11.1%) and wind (11.8%) are now each more than a tenth of the US total. Taken together, they constitute 22.9% of the US’s total available installed utility-scale generating capacity.
At least 25-30% of US solar capacity is in the form of small-scale (e.g., rooftop) systems that are not reflected in FERC’s data. Including that additional solar capacity would bring the share provided by solar + wind to more than a quarter of the US total.
With the inclusion of hydropower (7.7%), biomass (1.1%), and geothermal (0.3%), renewables currently claim a 32.0% share of total US utility-scale generating capacity. If small-scale solar capacity is included, renewables are now about one-third of total US generating capacity.
Solar is on track to become No. 2 source of US generating capacity
FERC reports that net “high probability” additions of solar between June 2025 and May 2028 total 89,513 MW – an amount almost four times the forecast net “high probability” additions for wind (23,019 MW), the second fastest growing resource.
FERC also foresees net growth for hydropower (596 MW) and geothermal (92 MW) but a decrease of 123 MW in biomass capacity.
Taken together, the net new “high probability” capacity additions by all renewable energy sources over the next three years – the bulk of the Trump Administration’s remaining time in office – would total 113,097 MW.
There is no new nuclear capacity in FERC’s three-year forecast, while coal and oil are projected to contract by 24,913 MW and 1,907 MW, respectively. Natural gas capacity would expand by 5,992 MW.
Thus, adjusting for the different capacity factors of gas (59.7%), wind (34.3%), and utility-scale solar (23.4%), electricity generated by the projected new solar capacity to be added in the coming three years should be nearly six times greater than that produced by the new natural gas capacity while the electrical output by new wind capacity would be more than double that by gas.
If FERC’s current “high probability” additions materialize by May 1, 2028, solar will account for 16.7% of US installed utility-scale generating capacity. Wind would provide an additional 12.7% of the total. Thus, each would be greater than coal (12.2%) and substantially more than nuclear power or hydropower (each 7.2%).
In fact, assuming current growth rates continue, the installed capacity of utility-scale solar is likely to surpass that of either coal or wind within two years, putting solar in the No. 2 spot for installed generating capacity, behind natural gas.
Renewables may overtake natural gas within 3 years
All utility-scale (i.e., >1 MW) renewables is now adding about two percentage points each year to its share of generating capacity. At that pace, by June 1, 2028, renewables would account for 37.8% of total available installed utility-scale generating capacity, rapidly approaching that of natural gas (40.2%). Solar and wind would constitute more than three-quarters of the installed capacity of renewable sources. If those trendlines continue, utility-scale renewable energy capacity should surpass that of natural gas in 2029 or sooner.
However, as noted, FERC’s data do not account for the capacity of small-scale solar systems. If that is factored in, within three years, total US solar capacity should exceed 300 GW. In turn, the mix of all renewables would be about 40% of total installed capacity, while natural gas’s share would drop to about 38%.
Moreover, FERC reports that there may actually be as much as 226,821 MW of net new solar additions in the current three-year pipeline in addition to 67,405 MW of new wind, 9,064 MW of new hydropower, 202 MW of new geothermal, and 34 MW of new biomass. By contrast, the net new natural gas capacity in the three-year pipeline potentially totals just 28,797 MW. Consequently, renewables’ share could be even greater by late spring 2028.
Renewables increase and fossil fuels shrink
At the end of 2024, the mix of all renewables accounted for 30.96% of total generating capacity. Solar alone was 10.19% while wind was 11.68%. By the end of May, renewables’ share had risen to 31.98% with solar at 11.13% and wind at 11.80%.
On the other hand, natural gas’s share had slipped from 43.00% to 42.52%, coal fell from 15.30% to 14.89%, and oil dropped from 2.73% to 2.72%. Similarly, nuclear power’s share of generating capacity decreased from 7.84% to 7.74%.
“FERC’s latest data predate enactment of the Trump Administration’s ‘Big, Beautiful Bill,’ which may adversely affect the future growth trajectories of wind and solar,” noted the SUN DAY Campaign’s executive director, Ken Bossong. “However, FERC’s forecasts suggest that cleaner and lower-cost renewable energy sources will continue to grow, retaining their lead over coal and nuclear power while closing the gap with natural gas.”

The storm hit. The power’s out. With all the damage around you, it looks like you might be without power for a few days (at least). But you planned for this. You have a home backup battery. What happens now?
If you’re considering a home backup battery, or you already have one and haven’t needed it yet, you might be wondering what you’re supposed to do when the inevitable happens. The good news is: you probably won’t have to do much at all.
Whether you’ve got an industry standard like the Tesla Powerwall, one of the new GM Energy Storage Bundles, or any of the other excellent home battery systems on the market, from your point of view they’ll function in pretty much the same way.
Step 1: do nothing
Modern home batteries are paired with an automatic transfer switch. That’s a switch, usually installed near your home’s electrical panel, that allows you to go from grid power, to battery, and back. And, because it’s automatic, you don’t have to do anything at all.
The instant the grid goes down, the automatic transfer switch recognizes the loss of power and automagically disconnects your house from the grid, seamlessly connecting it to your backup battery instead. Your lights stay on, the refrigerator keeps humming, and whatever else you’ve chosen to back up just keeps on keeping on. In some cases, the transition to battery power happens so smoothly that you might not even realize the neighborhood’s lost power, not noticing the neighbors’ dark windows until you step outside.
When the power comes back, that side of the switch gets energized, and it does its thing again, only in reverse – switching you back from battery to grid power and intelligently re-charging the battery in anticipation for the next blackout.
How long will my battery last?
Unfortunately, this is one of those questions that doesn’t have an easy answer. In the simplest terms, if you have a small battery and try to keep the AC running, you might run out of juice in a few hours. On the other hand, if you have great big battery and save its electrons for just the barest essentials (a few lights, a laptop, and a phone or radio, for example) you might never run out of power.
To put some numbers to that, a 31 cu. ft. Samsung RF32CG5400SRAA stainless steel refrigerator is rated at 785 kWh/year. That works out to about 2.15 kWh/day. Factor in 20-40% higher energy needs for warmer temperatures, a few daily door openings, defrost cycles, inverter losses, etc. and you’re looking at 18-22 kWh of usable battery capacity to keep that thing running for a full week on battery power. Now do that same math for every appliance you deem a “must have,” then do the “nice to haves,” and on down the line.
That doesn’t even address the other form of “last,” and whether you’re looking for a ten- or twenty- year battery solution.
What you need to do, in other words, is talk to the experts. Let them know what appliances you need to keep running, how long you want to prepare for, and let them do the math to help determine which battery solution is right for you.
I’ve included a video that covers the process of picking a solar battery from EnergySage (a trusted affiliate partner), below, and invite you to share some of your own backup battery-picking experiences in the comments.

Just days after Chevrolet beat the mighty Ford Mustang GTD’s Nürburgring track record with their Corvette ZR1 and ZR1X, Ford went back to the ‘Ring to reclaim some glory. They didn’t bring a Mustang along, though – they showed up with an electric van, and record-setting hot shoe Romain Dumas behind the wheel.
* it’s not your typical van. It’s a SuperVan.
Ford took back a fair bit of Chevy’s headline-grabbing glory this week when LeMans-winning driver Romain Dumas lapped the 12.9 mile Green Hell in just 6 minutes and 48.393 seconds – a blazing performance that makes the 2000 hp Ford SuperVan 4.2 the ninth fastest car to ever blast around the storied German racetrack.
Dumas is no stranger to the Nürburgring’s Nordschleife. He was first overall at the 2007 24 hour race there. He also holds the outright Nürburgring track record for EVs, which he set back in 2019 behind the wheel of the Volkswagen ID.R, completing the circuit in 6 minutes and 05.336 driving the Volkswagen ID.R.
The new ‘Ring-record comes just a few weeks after Ford beat out every other supercar at the Goodwood Festival of Speed in the UK with its all-electric SuperTruck, crushing the “competition” with their 1,400 hp prototype EV silhouette racer.
No word yet on what track record Ford plans to snatch with an EV next.
Electrek’s Take
If there were still Ford guys and Chevy guys, I like to think I’d be a Mopar guy – but even from the sidelines, I can tell that Chevy’s been having a rough couple of weeks, performance-wise. Not only did their top-shelf ZR1X get beaten by a Ford van (even if it is a SuperVan), but their clean sheet, future-thinking, pie-in-the-sky concept Corvette got beat to the hypercar headlines by a Chinese rival with 1,000 extra hp.
Take my advice, GM: it’s time to drag Warren Mosler back home from the Virgin Islands, figure out where Rod Trenne’s hiding, and get them to build you a proper, 900 kg electric ‘Vette. Y’all let me know if you need help setting that up.

EV drivers who use the Pennsylvania Turnpike just got a jolt of good news: Two Applegreen DC fast charging stations have come online, adding to the growing network of over 60 EV chargers along the 360-mile toll road that links Pittsburgh, Harrisburg, and Philadelphia.
The new 400 kW Applegreen Electric charging stations are at the PA Turnpike’s North Somerset (MP 112.3 westbound) and South Somerset (MP 112.3 eastbound) Service Plazas. Each site includes two DC fast chargers for a total of four charging ports, with two NACS and two CCS plugs at each service plaza. The PA Turnpike says the sites are equipped to be expanded.
The Pennsylvania Turnpike plugged in its first EV charger in April 2014. A decade later, more than 60 charging stations are online at eight of its service plazas, giving EV drivers a reliable boost across the state. And thanks to a new partnership with Applegreen Electric, 80 new universal EV chargers are on the way. By 2027, all 17 service plazas will feature DC fast chargers.
“We are pleased to offer our EV customers convenient access to the latest, fastest technology – without leaving the PA Turnpike,” said Director of Facilities Operations Keith Jack.
The EV chargers at North Somerset and South Somerset, along with an EV charger at the Hickory Run Service Plaza scheduled to open this fall, were funded with grants from the Pennsylvania Department of Environmental Protection’s Driving PA Forward program. The chargers at nine service plazas scheduled to open in 2027 are being funded through grants from the Biden administration’s federal National Electric Vehicle Infrastructure (NEVI) program.
Applegreen Electric chief executive Eugene Moore noted that the PA Turnpike’s fast charger rollout “marks a key step in building a connected corridor with Pennsylvania as a vital part of the seamless network that now spans New Jersey, New York, Connecticut, and Delaware. With more to come soon in Ohio and Massachusetts, we’re accelerating the rollout of reliable, accessible EV infrastructure across the region.”
Applegreen is deploying fast chargers on the New Jersey Turnpike, with which it now has an exclusive agreement – it’s taking over from Tesla.
