September was tied for the hottest of any September on record globally. It was also a very hot month for renewable energy in the US. According to figures from the Federal Energy Regulatory Commission, wind and solar accounted for all new electricity capacity added to America’s grid in September.

The projects consisted of five wind farms totaling 300 megawatts and 18 solar installations totaling 133 megawatts:

Renewable energy Analyst Kenneth Bossong initially reported on the figures.

“The remarkable expansion of renewable energy’s contribution to the nation’s electrical supply reflects continuing declines in costs, the impact of state renewable electricity standards, and the mix of tax and other incentives provided by the federal government,” said Bossong in an emailed statement.

As the chart above shows, the US has seen 4,055 MW of wind, 936 MW of solar, 340 MW of biomass, 123 MW of geothermal, 9 MW of hydro, and 3 MW of waste heat projects come online since January. This represents a 29 percent increase over the same period in 2011.
