Wind and solar in March accounted for 10% of U.S. electricity generation for fir

For the first time, monthly electricity generation from wind and solar (including utility-scale plants and small-scale systems) exceeded 10% of total electricity generation in the United States, based on March data in EIA’s Electric Power Monthly. Electricity generation from both of these energy sources has grown with increases in wind and solar generating capacity. On an annual basis, wind and solar made up 7% of total U.S. electric generation in 2016.

Electricity generation from wind and solar follows seasonal patterns that reflect the seasonal availability of wind and sunshine. Within the United States, wind patterns vary based on geography. For example, wind-powered generating units in Texas, Oklahoma, and nearby states often have their highest output in spring months, while wind-powered generators in California are more likely to have their highest output in summer months.

Monthly solar output is highest in the summer months, regardless of location, because of the greater number of daylight hours. About half of all utility-scale solar power plants in the United States use some form of sun-tracking technology to improve their seasonal output.
