62% Natural Gas (90% of the added capacity is stated to have consisted of combined-cycle generators)
-
21% Wind (noting Texas, Iowa, and Oklahoma added a combined 4.0 gigawatts of wind capacity)
-
17% Solar Photovoltaic (60% of the additions were incurred in California, Florida, and Oklahoma)
The remaining two percent of additions are stated to have originated primarily from hydroelectric and battery storage capacity.
