US solar and wind growth defies expectations – a decade in numbers
The latest US EIA and FERC data reflect a decade of explosive solar and wind growth – here’s how it breaks down.
The SUN DAY Campaign reviewed EIA’s latest monthly “Electric Power Monthly” report (with electrical generation data through June 30, 2024) and compared it to EIA’s data for June 30, 2019 and for June 30, 2014. It also examined FERC’s latest monthly “Energy Infrastructure Update” report (with installed generating capacity data through June 30, 2024) and likewise compared it to FERC’s data for June 30, 2019 and for June 30, 2014.
The installed US generating capacity mix of all renewable energy sources (i.e., biomass, geothermal, hydropower, solar, and wind) now totals 389 gigawatts (GW). That’s over 50% greater than five years ago (258.58 GW) and more than double the renewable energy capacity that existed a decade ago (190.26 GW). Most of the growth is because of new solar and wind capacity.
Similarly, electrical generation by renewables has shown strong growth. Ten years ago, renewables provided 14.28% of the nation’s electrical generation. Five years later, it had grown to 20.11% and today stands at 26.01%. Again, most of the increase is due to wind and solar.
For the first half of 2024, renewables, including small-scale solar, provided 549,339 gigawatt-hours (GWh) of electrical generation. That’s almost 40% more than the amount renewables generated in the first half of 2019 (399,586 GWh) and nearly double the output reported for the first half of 2014 (287,136 GWh).
Over the past decade, wind has become a leader
Ten years ago, hydropower boasted about 62% more capacity than wind (99.64 GW vs. 61.45 GW) and generated 40% more electricity (140,659 GWh vs. 99,739 GWh).
Five years later, the two were nearly equal in both capacity (hydro: 100.73 GW vs. wind: 98.86 GW) and electrical generation (hydro: 153,790 GWh vs. wind: 154,338 GWh).
Now, however, wind has definitively overtaken hydropower with 152.64 GW of installed capacity compared to that of hydro (100.88 GW) as well as 247,435 GWh of actual electrical output during the first six months of 2024 compared to 126,139 GWh from hydro.
As of mid-2024, wind accounted for 11.72% of total US electrical generation. Five years prior, it was 7.77%, and a decade ago, its share (4.96%) was less than half of today’s figure.
Wind’s share of total installed generating capacity as of June 30, 2024, was 11.75% – a significant increase from its 8.25% share five years earlier and 5.26% a decade ago.
Solar is the fastest-growing source of new capacity and generation
In the past decade, solar has ballooned from a fraction of a percent of both capacity and generation to become the second-largest renewable in both categories.
At the end of June 2014, utility-scale solar provided a mere 9.25 GW (0.75%) of total installed US generating capacity. Generation by utility-scale solar (8,535 GWh) was only 0.42% of the US total and EIA wasn’t even reporting generation by distributed, small-scale (i.e., <1 MW) systems yet.
However, five years later, solar capacity (39.13 GW) accounted for 3.27% of total utility-scale capacity. Actual generation by utility-scale facilities in the first half of 2019 had risen more than fourfold to 36,042 GWh (1.81% of the total) with small-scale solar contributing an additional 17,520 GWh (0.88%).
By the middle of 2024, installed solar capacity had risen to 8.99% of total utility-scale capacity. Utility-scale systems generated 102,614 GWh (4.86%) and small-scale systems added another 42,449 GWh (2.01%).
This rate of solar and wind growth has defied expectations. Three years ago, FERC had projected that installed utility-scale solar capacity would reach 105.04 GW by mid-year 2024. Solar’s actual capacity today is 11.2% more than FERC’s earlier forecast. In addition, wind’s installed capacity is now 2.4% higher than FERC had anticipated.
Hydropower and geothermal ebbs and flows, biomass drops
Over the past decade, the installed capacity of hydropower has edged up very slowly from 99.64 GW in June 2014 to 100.73 GW five years later and 100.88 GW today. Because the installed capacity of all energy sources combined has grown by over 8% during the past 10 years, hydropower’s share of capacity has gradually declined from 8.57% in 2014 to 8.41% in 2019, to 7.77% in 2024.
Electrical generation by US hydropower facilities has ebbed and flowed from year to year. For example, it was 140,65 GWh in the first half of 2014 (7% of the total) and then 153,790 GWh in mid-2019 (7.74%) and is now 126,139 GWh (5.97%) for the first six months of 2024.
Electrical generation by biomass, as well as its share of installed generating capacity, has been on a slow decline for the past 10 years. FERC data indicate that utility-scale biomass capacity dropped from 16.05 GW (1.37% of the total) in mid-2014 to 16.02 GW (1.34%) in mid-2019 to 14.54 GW (1.12%) in mid-2024. Correspondingly, actual electrical generation fell from 30,095 GWh (1.50%) during the first half of 2014 to 29,520 GWh (1.49%) five years later and then to 23,062 GWh (1.09%) this year.
The smallest renewable energy source – geothermal – has shown a pattern similar to that of hydropower. Its installed capacity has risen slightly from 3.87 GW in 2014 to 4.14 GW today, while its share of the US total has consistently hovered around 0.32-0.33%. Actual generation has ebbed and flowed over the past decade providing 8,108 GWh (0.40%) in the first six months of 2014, then 8,376 GWh (0.42%) in the first half of 2019, and now 7,640 GWh (0.36%).
“Notwithstanding minimal changes in the contributions by hydropower, biomass, and geothermal, renewable energy sources have doubled their share of US generating capacity and electrical output over the past 10 years thanks to explosive growth by both wind and solar,” noted the SUN DAY Campaign’s executive director Ken Bossong. “If the trends of the preceding decade continue, renewable energy sources could account for 40% or more of capacity and actual generation by 2035.”

Mammoth Solar, a 1.3 gigawatt (GW) solar farm in northern Indiana, is now powering into its biggest construction phase yet, cementing its place as one of the largest solar projects in the US.
The solar farm is set to increase Indiana’s solar capacity by more than 20% once it’s fully online. And with construction ramping up this month, developer Doral Renewables has given Bechtel Full Notice to Proceed on the design, engineering, and construction of three major phases of the project: Mammoth South, Mammoth Central I, and Mammoth Central II. Together, these phases will generate 900 MW of clean energy.
That’s enough electricity to power around 200,000 homes with clean energy, helping Indiana shift away from fossil fuels while boosting the local economy.
Construction is already underway, and over the next two years, Bechtel will install around 2 million solar panels, with about half of them made in the US. The company is also handling all engineering, procurement, and construction work, using its digital project management tools and autonomous tech to keep everything on track.
At the peak of the buildout, Mammoth Solar is expected to create over 1,200 jobs, with at least 15% of those set aside for apprenticeships.
Bechtel says its success will hinge on strong collaboration with local trades and vendors. The company is working closely with craft professionals and is committed to being a reliable community partner throughout construction.
Once the solar farm is complete in 2027, Doral Renewables plans to roll out agrivoltaics across the site. That means livestock grazing and crop cultivation will happen right alongside energy production, giving farmers in the area a way to keep working their land while supporting clean energy development.

BYD is about to launch an even smaller EV, but this one’s a little different. It’s BYD’s first kei car. You know, those tiny vehicles that dominate Japan’s city streets? BYD’s mini EV was just spotted out in public, giving us our first real look at the upcoming kei car.
BYD’s first mini EV was spotted in public
Last week, rumors surfaced that BYD was developing its first kei car, which would compete with top-selling models from Nissan, Honda, Mitsubishi, and other Japanese brands.
Kei cars, or “K-Car,” as they are sometimes called, are a class of ultra-compact vehicles that cannot be longer than 3.4 meters (134″). To put that into perspective, BYD’s smallest EV currently, the Seagull (called the Dolphin Mini overseas), is 3,780 mm (148.8″) long.
The mini vehicles are ideal in Japan because they are so small, making it easy to get around tight city streets. They are also more affordable and efficient than larger vehicles.
BYD’s mini EV was spotted for the first time during a road test this week by IT Home (via CarNewsChina), revealing a familiar look. It has that boxy, compact look of a typical kei car with sliding side doors.
According to reports, BYD is developing a new platform for the model. It will reportedly include a 20 kWh battery, good for 180 km (112 miles) WLTC range. By using its in-house Blade LFP batteries, BYD is expected to have a cost advantage.
BYD’s upcoming mini EV is expected to start at around 2.5 million yen, or about $18,000. That’s about the same as the Nissan Sakura (2.59 million yen), Japan’s best-selling EV last year.

Last year, around 1.55 million kei cars were sold in Japan, accounting for roughly 40% of new vehicle sales. Honda’s N-Box was the top-selling kei car (EV or gas) for the third straight year.
As Nikkei reported, some are already calling BYD’s electric kei car “a huge threat.” A Suzuki dealer said, “Young people do not have a negative view of BYD. It would be a huge threat if the company launches cheap models in Japan.”
BYD already sells several electric cars in Japan, including the Atto 3 SUV, Dolphin, and Seal. Last month, the company launched the new Sealion 7 midsize electric SUV, starting at 4.95 million yen ($34,500).
Although Japan isn’t really an EV hot spot, with sales falling 33% in 2024 to just under 60,000 units, BYD sees an opportunity.
By making virtually every car component in-house, including batteries, BYD can offer EVs at such low prices while still making a profit. BYD’s cheapest and best-selling electric car, the Seagull, starts at under $10,000 (69,800 yuan) in China.
With new smart driving and charging tech rolling out, BYD’s electric cars are getting smarter and even more efficient.
Can BYD’s mini EV compete with Japanese brands? At the right price, it may have a chance. Check back soon for more on the upcoming kei car. We’ll keep you up to date with the latest.

Ford’s electric pickup truck is back at the top. The F-150 Lightning is once again the best-selling electric pickup in the US after overtaking the Tesla Cybertruck in the first quarter.
Ford’s F-150 Lightning is the best-selling electric pickup
After launching in 2023, Tesla’s Cybertruck quickly outpaced the Lightning to become America’s top-selling EV pickup last year.
Since Tesla doesn’t break down regional sales, registration data gives us our best estimate. The latest registration data from S&P Global Mobility (via Automotive News) shows that the F-150 Lightning retook the title in March and the first quarter of 2025.
Ford’s electric pickup notched 2,598 registrations in March, topping the Tesla Cybertruck with 2,170. In the first quarter, the F-150 Lightning remained ahead with 7,913 registrations, compared to the Cybertruck’s 7,126.
Although the Cybertruck was the fifth top-selling EV in the US last year, it didn’t even crack the top ten in March. It placed ninth through the first three months of 2025, behind the Volkswagen ID.4.
While Tesla and Ford remained the leaders in the electric pickup market, several new models are gaining momentum. According to the most recent numbers from Cox Automotive, GM sold 2,383 Chevy Silverado EVs and 1,249 GMC Sierra EV models in Q1. Meanwhile, Rivian sold 1,727 R1Ts during the quarter.
Earlier today, Electrek reported that new models, including the Honda Prologue and Chevy Blazer EV, helped drive EV registrations up 20% in the US in March.
Although the Lightning reclaimed the crown from Tesla, Ford’s electric pickup isn’t exactly flying off the lot. Ford reported Lightning sales fell 16% to just 1,740 units in April. Through April 2025, Ford has sold 8,927 electric trucks, down 9% from the 9,833 it handed over last year.
Electrek’s Take
To be fair, Tesla is still ahead by a wide margin in the US. The S&P numbers show Tesla had over 51,000 registrations in March, up 1% after two months of lower YOY growth.
GM’s Chevy surpassed Ford to become the second-best-selling EV brand with nearly 8,500 registrations, an increase of 274% from last year. Ford dropped to third with 7,361 registrations.
Although it’s just one quarter, it’s starting to show how Tesla CEO Elon Musk’s political antics are likely impacting sales. After the Cybertruck’s initial hype, it appears many buyers are opting for traditional pickups, like the F-150 Lighting.
Meanwhile, Ram is delaying its first electric pickup, the 1500 REV, again. Ram is pushing production back until summer 2027, saying it’s “extending the quality validation period.” The plug-in hybrid (PHEV) Ramcharger will also be delayed until the first quarter of 2026.
After pulling the Ramcharger ahead of the fully electric version last year, Stellantis blamed weak demand for EV pickups in the US.
