Renewables provided 90% of new US capacity in 2024 – FERC
Renewable energy – solar, wind, geothermal, hydropower, biomass – accounted for more than 90% of total US electrical generating capacity added in 2024, according to data released yesterday by the Federal Energy Regulatory Commission (FERC) and reviewed by the SUN DAY campaign.
Solar alone accounted for over 81% of the new capacity. Moreover, December was the 16th month in a row in which solar was the largest source of new capacity.
Renewables made up the lion’s share of new generating capacity in December and in 2024. In its latest monthly “Energy Infrastructure Update” report (with data through December 31, 2024), FERC says 105 “units” of solar totaling 4,369 megawatts (MW) came online in December, along with two units of wind (324 MW) and two units of biomass (45 MW). Combined, they accounted for 86.9% of all new generating capacity added during the month. Natural gas provided the balance: 717 MW.
During the full 2024 calendar year, solar and wind added 30,816 MW and 3,128 MW, respectively. Combined with 213 MW of hydropower, 51 MW of biomass, and 29 MW of geothermal steam, renewables accounted for 90.5% of added capacity. The balance consisted of the 1,100 Vogtle-4 nuclear reactor in Georgia, plus 2,428 MW of natural gas, 13 MW of coal, 11 MW of oil, and 28 MW of “other.”
Solar was 80.1% of new capacity in December and 81.5% during 2024. Solar accounted for 81.5% of all new generating capacity placed into service in 2024 – 50% more than the solar capacity added in 2023.
In December alone, solar comprised 80.1% of all new capacity added.
New solar capacity added in 2024 is almost nine times that added by natural gas and nuclear power combined.
Solar has now been the largest source of new generating capacity added each month for 16 months straight, from September 2023 – December 2024.
Adjusting for the differences in capacity factors among solar, nuclear, and natural gas, the new solar capacity added in 2024 is likely to generate seven times as much electricity as the new nuclear capacity and about five times as much as might be expected from the new natural gas capacity.
Solar + wind are now almost 22% of US utility-scale generating capacity. New wind accounted for much of the balance (8.3%) of capacity additions, which is more than either the new natural gas capacity (6.4%) or nuclear power capacity (2.9%).
Taken together, the installed capacities of just solar (10.2%) and wind (11.7%) now constitute more than one-fifth (21.9%) of the US’s total available installed utility-scale generating capacity.
However, approximately 30% of US solar capacity is in the form of small-scale (e.g., rooftop) systems that aren’t reflected in FERC’s data. Including that additional solar capacity would bring the share provided by solar + wind closer to a quarter of the US total.
With the inclusion of hydropower (7.7%), biomass (1.1%), and geothermal (0.3%), renewables now claim a 31.0% 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’s share of US generating capacity is now 10x greater than a decade ago. As noted, by the end of 2024, solar and wind accounted for 10.2% and 11.7%, respectively, of all installed utility-scale generating capacity in the US, while the mix of all renewables accounted for 31.0%.
In December 2023, FERC reported that solar and wind were 7.9% and 11.7% of installed capacity while the mix of all renewables provided 29.0%.
Five years ago (December 2019), FERC released data showing solar and wind to be 3.5% and 8.5% of total capacity while all renewables combined were 22.1%.
A decade ago (December 2014), FERC reported that solar and wind were 1.0% and 5.5% of total capacity, while the combination of all renewables accounted for 16.6% of capacity.
Solar will soon become the second-largest source of US generating capacity. FERC reports that net “high probability” additions of solar between January 2025 and December 2027 total 91,558 MW – an amount almost four times the forecast net “high probability” additions for wind (23,601 MW), the second-fastest growing resource. FERC also foresees growth for hydropower (1,345 MW), geothermal (90 MW), and biomass (61 MW).
Taken together, the net new “high probability” capacity additions by all renewable energy sources would total 116,655 MW, with solar comprising over 78% and wind providing another 20%.
On the other hand, there is no new nuclear capacity in FERC’s three-year forecast, while coal, oil, and natural gas are projected to contract by 23,925 MW, 2,293 MW, and 833 MW, respectively.
If FERC’s current “high probability” additions materialize, by January 1, 2028, solar will account for nearly one-sixth (16.1%) of the US’s installed utility-scale generating capacity. That would be greater than either coal or wind (both 12.6%) and substantially more than either nuclear power or hydropower (both 7.3%).
In fact, assuming current growth rates continue, the installed capacity of utility-scale solar is likely to surpass coal and wind within the next two years, placing solar in second place for installed generating capacity, behind natural gas.
Meanwhile, the mix of all renewables is now adding about two percentage points each year to its share of generating capacity. Thus, by January 1, 2028, renewables would account for 37.3% of the total available installed utility-scale generating capacity – rapidly approaching that of natural gas (40.2%) – with solar and wind constituting more than three-quarters of the installed renewable energy capacity.
All renewables combined are on track to exceed natural gas within three years. As noted, FERC’s data don’t account for the capacity of small-scale solar systems. If that’s factored in, within three years, total US solar capacity could surpass 320 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%.
Moreover, FERC reports that there may actually be as much as 222,443 MW of net new solar additions in the current three-year pipeline in addition to 68,815 MW of new wind, 8,659 MW of new hydropower, 199 MW of new geothermal, and 127 MW of new biomass. By contrast, the net new natural gas capacity potentially in the three-year pipeline totals just 19,438 MW. Thus, the share of renewables share could be even greater by early 2028.
“For more than a decade, renewable energy sources – led by solar – have dominated growth in US generating capacity,” noted the SUN DAY Campaign’s executive director Ken Bossong. “Consequently, efforts by the Trump Administration to reverse this trend are both illogical and likely to fail.”
Electrek’s Take
FERC’s latest data further illustrates how utterly ridiculous Trump’s “national energy emergency” executive order is. The steady growth of clean energy, which has kept large energy markets like Texas out of trouble during weather events, disproves Trump’s claims that the US clean energy supply is “precariously inadequate and intermittent.”
Further, his refusal to even define solar and wind as “energy” in that executive order isn’t going to stop their progress, and both he and his new secretary of energy, Chris Wright, telling lies about renewables isn’t going to make them any less clean, affordable, or reliable.

For the last few weeks, we’ve been running a sidebar survey about how much Electrek readers think it would cost to add EV charging systems to their homes. After receiving over twenty-four hundred responses, here’s what you told us.
In our previous survey, we asked readers why they chose to install solar panels at home. In the recap, many of our commenters mentioned having their systems systems pull double duty — charging home backup batteries and topping off their electric cars. That got us thinking: as more and more first-time EV owners look into the many benefits of home charging, how much do they expect to pay for home charging?
Based on over 2,400 responses, this is what you told us.
What do you expect to pay for home charging?
The most positive surprise was that more than a third of Electrek readers who responded to the poll already had 240V outlets in their garage, so they expected to pay effectively $0 – their homes are EV ready now!
Of the remaining 64%, 44% were fairly evenly split between a relatively straightforward ~$500-1,000 wiring job with a few wiring or panel upgrades while only about 18% expected to spend over $1,000 due to having an older home, a detached garage, or for some other (apparently pricey and/or inconvenient) reason.
Navigating the questions
Just like you would for home solar, we’d recommend getting a quote from several installers before making a decision. One of our trusted partners, Qmerit, offers a quote-sourcing service called PowerHouse. The service scans pricing from thousands of completed electrification installations across North America to provide the best quotes that take regional variability into account and work with homeowners to “bundle” chargers, installation, and even batteries.
America has arrived at an inflection point in which all of the technical, policy and financial elements are in place to support a societal shift toward whole-home electrification. Now what’s needed is a comprehensive way to assemble these complex elements into a simple, financeable, home-energy retrofit that makes it easier to implement.
QMERIT FOUNDER TRACY PRICE
Qmerit says its new bundling program can flag the potential for federal, state, and local utility incentives like the ones we’ve covered from Illinois utility ComEd and others that can reduce or even eliminate the upfront costs of home installations for many.

Following a lawsuit brought against the California Air Resources Board (CARB) by major heavy truck manufacturers over California’s emissions requirements, CARB has struck back with fresh lawsuit of its own alleging that the manufacturers violated the terms of the 2023 Clean Truck Partnership agreement to sell cleaner vehicles.
Daimler Truck North America, International Motors, Paccar and Volvo Group North America sued the California Air Resources Board in federal court this past August, seeking to invalidate the Clean Truck Partnership emissions reduction deal they signed with the state in 2023 to move away from traditional trucks and toward zero-emission vehicles (ZEVs). The main point of the lawsuit was that, because the incoming Trump Administration rolled back Environmental Protection Agency (EPA) policies that had previously given individual states the right to set their own environmental and emissions laws, the truck makers shouldn’t have to honor the deals signed with individual states.
“Plaintiffs are caught in the crossfire: California demands that OEMs follow preempted laws; the United States maintains such laws are illegal and orders OEMs to disregard them,” the lawsuit reads. “Accordingly, Plaintiff OEMs file this lawsuit to clarify their legal obligations under federal and state law and to enjoin California from enforcing standards preempted by federal law.”
After several weeks of waiting for a response, we finally have one: CARB is suing the OEMs right back, claiming that the initial suit proves the signing manufacturers, “(have) unambiguously stated that they do not intend to comply.”
They want to sell Americans more diesel
In its lawsuit, CARB argues that monetary damages alone would not make the people of the State of California whole as far as damages are concerned, citing that the stated goal of the 2023 Clean Truck Partnership was, “to achieve emissions reductions that cannot be measured strictly in financial terms,” according to ACT-News.
The agency is asking the court to compel the truck companies to perform on their 2023 obligations or, failing that, to allow CARB to rescind the contract and recover its costs. A hearing on the truck makers’ request for a preliminary injunction was held Friday, with another court date set for November 21, when CARB will seek to dismiss the case brought forth by the truck brands. The outcome of these cases could shape how state and federal government agencies cooperation on emissions rules in the future.
You can read the full 22-page lawsuit, below, then let us know what you think of CARB’s response (and their chances of succeeding) in the comments.

Starting this month, parking lots in South Korea with more than 80 spaces will be required to install solar canopies and carports. But, unlike similar laws that have been proposed in the US, this new law doesn’t just apply to new construction – existing lots will have to comply as well!
South Korea’s Ministry of Trade, Industry and Energy announced in August that it has prepared an amendment to the Enforcement Decree of the Act on the Promotion of the Development, Use, and Diffusion of New and Renewable Energy to the effect that all publicly- and privately-owned parking lots in the Asian country with room for more than 80 vehicles will be compelled to add solar panels to their lots in a move designed to proactively expand renewable energy and create more solar and construction jobs.
In addition to creating jobs and working to stabilize the local grid with more renewable energy, the proposed solar canopies will offer a number of practical, day-to-day benefits for Korean drivers, as well.
The shaded structures will protect vehicles from heavy rain, snow, and the blistering summer sun — keeping interiors cooler, extending the life of plastics and upholstery, and even helping to preserve battery range in EVs and PHEVs by reducing their AC loads (and, of course, provide charging while the cars are parked).
To their credit, Ministry officials absolutely get it. “Through this mandatory installation,” one unnamed official told Asia Business Daily, “we expect to expand the distribution of eco-friendly renewable energy generation facilities while providing tangible benefits to the public. By utilizing idle land such as parking lots, we can maximize land use efficiency. In addition, installing canopy-type solar panels can provide shade underneath, offering noticeable comfort to people using parking lots during hot weather.”
The new rule was approved in late September, and is expected to go into effect later this month, with new installation projects set to begin immediately.
It could work here
South Korea is proving that an idea like is practical. Here in the US, we’re proving that out, too – the Northwest Fire District in Arizona partnered with Standard Solar to build a conceptually similar, 657 kW solar carport system across 12 parking lots (shown, above) that delivers more than 1.23 million kWh of clean, emissions-free power annually and offsets the equivalent of 185,000 vehicles’ worth of harmful carbon emissions.
That’s just Arizona. In New York, a new initiative to help expand solar into parking lots has more than doubled commercially zoned land where EV charging stations can be sited, “freeing up” an additional 400 million square feet of space throughout the city.
Sun-rich states like Texas, New Mexico, and Florida could also benefit, and even if we’re “just” adding fresh energy sources to municipal parking, dealer lots, and public schools, we could do a lot to reduce the cost of energy generation for the entire community. And, for what it’s worth, that seems to be right in line with the big reasons why people are choosing to add solar to their homes today.
What do you guys think – would something like this work in the US, or are we too far gone down the sophomoric, pseudo-libertarian rabbit hole to ever dig our way out? Let us know your take in the comments.
