A review by the Sun Day campaign of Data is released by the Federal Energy Regulatory Commission (FERC) It appears that the combination of solar and wind was good for almost 96% of the new American electric-generating capacity that was added in the first third of 2025. In April, Solar offered 87% of the new capacity, making it the twentieth consecutive month in which Solar took the lead.
Solar was 87% of the new generating capacity in April and 78% years to date:
In the last monthly report “Energie -Infrastructure Update” (with data up to and including 30 April 2025), FERC 50 “Units” of Solar Energy of 2,284 MW says in use, accounting for 86.7% of all new generating capacity that was added during the month.
Moreover, during the first four months of 2025, the 9,451 MW of Zonne-Zonne energy was more than three-quarters (77.7%) of the new generation that was taken into use.
Solar is now the largest source of new generating capacity that has been added every month for twenty consecutive months: September 2023 to April 2025.
Solar + Wind was added almost 96% of the new capacity in the first third part of 2025:
Between January and April, New Wind has yielded 2.183 MW of capacity additives, which means that 18% of the new additions during the first four months of 2025 are good.
For the first third of the year, the combination of solar and wind was 95.7% of the new capacity, while natural gas (511 MW) delivered only 4.2%; The remaining 0.1% came from oil (11 MW).
Zonne-Plus Wind is almost a quarter of the generating capacity in the field of utility scale; All combined renewable energy sources are almost a third:
The installed capacities of solar energy (11.0%) and wind (11.8%) are now each more than one tenth of the total of the nation. All in all, they are almost a fourth (22.8%) of the total available generation capacity of the US.
At least 25 to 30% of American solar capacity is located in the form of small -scale (for example roof) systems that are not reflected in Ferc’s data. The inclusion of that extra solar capacity would bring the share of Solar + Wind to more than a quarter of the total of the nation.
With the absorption of hydropower (7.7%), biomass (1.1%) and geothermal (0.3%), renewable energy sources currently claim a share of 31.8%of the total generating capacity in the field of US Utility scale. If small -scale solar capacity is included, renewable energy sources are now around a third of the total American -generating capacity.
Zonnee stays on the right track to become the second largest source of generating capacity:
Ferc reports that the additions of the net “high probability” of solar energy between May 2025 and April 2028 a total of 90.158 MW – an amount almost four times the prediction net “high probability” additions for wind (22.793 MW), the second fastest growing source. In particular, both three -year projections are granted higher than just a month earlier.
Ferc also provides net growth for hydropower (596 MW) and geothermal (92 MW) but a decrease of 123 MW in biomassa capacity.
In summary, the net new additions of ‘high probability’ capacity through all renewable energy sources in the next three years – ie most of the remaining time of the Trump administration in function – in function – a total of 113,516 MW.
On the other hand, there is no new nuclear capacity in Ferc’s three -year prediction, while coal and oil are expected to contract with 24,373 MW and 1,915 MW respectively. Natural gas capacity would expand with 5,730 MW.
Thus, the adjustment of the various capacity factors of gas (59.7%), wind (34.3%) and on utility scale Zonne-Zonne-Zon (23.4%) would be generated by the expected new solar capacity that will be added in the coming three years, at least six times larger than the newte-hipage, while the electrical gamage, while the electrical gamacy, while the electrical gamage, while the electrical gas capacity, while the electrical gas capacity, The case would be double of the gas.
If the current additions of “high probability” of FERC occur, Solar will be by 1 May 2028 for a sixth (16.6%) of the installed generating capacity of the nation on utility scale. Wind would offer an extra eighth (12.6%) of the total. Thus each would be larger than coal (12.2%) and considerably more than nuclear energy or hydropower (7.3%and 7.2%respectively).
Assuming that the current growth rates will continue, the installed capacity of solar energy on utility scale will probably surpass those of coal or wind within two years, so that solar energy is placed in second place for installed generating capacity-behind only natural gas.
The combined capacities of all renewable energy sources, including small-scale solar energy, can catch up with natural gas within three years:
The mix of all renewable energy sources on utilities (ie> 1 MW) now adds approximately two percentage points to its share in the generating capacity every year. At that pace, by 1 May 2028, renewable energy sources three-eight (37.7%) of the total available generating capacity in the field of Nutschart-fast approach of that of natural gas (40.1%) would approach. Solar and wind would be more than three-quarters of the installed capacity for renewable energy. If those trend lines continue, the capacity on utility scale should surpass that of natural gas in 2029 or earlier.
As noted, however, Ferc’s data has not been taken into account the capacity of small -scale solar systems. If that is processed within three years, the total American solar capacity (ie small-scale plus utility scale) could exceed 300 GW. In turn, the mix of all renewable energy sources would then be around 40% of the total installed capacity, while the share of natural gas would fall to around 38%.
Moreover, Ferc reports that there may be 224,426 MW of net new solar additives in the current three -year pipeline, in addition to 69,530 MW New Wind, 9,072 MW New Water power, 202 MW new geothermal and 39 MW new biomass. Netto new natural gascol capacity, on the other hand, potential in the three -year pipeline is only 26,818 MW. Consequently, the share of Renewables can be even greater against the Mid-Spring 2028.
“The ‘large, beautiful Bill’ of the Trump government that is now being discussed by the Republican controlled congress is a clear threat to solar energy and wind in the coming years,” noted the executive director of the Sun Day Campaign Ken Bossong. “Nevertheless, Ferc’s newest data and predictions suggest that cleaner and cheaper renewable energy sources still dominate and can surpass nuclear energy, coal and natural gas.”
