For a initial time, monthly electricity era from breeze and solar (including utility-scale plants and small-scale systems) exceeded 10% of sum electricity era in a United States, formed on Mar information in EIA’s Electric Power Monthly. Electricity era from both of these appetite sources has grown with increases in breeze and solar generating capacity. On an annual basis, breeze and solar done adult 7% of sum U.S. electric era in 2016.
Electricity era from breeze and solar follows anniversary patterns that simulate a anniversary accessibility of breeze and sunshine. Within a United States, breeze patterns change formed on geography. For example, wind-powered generating units in Texas, Oklahoma, and circuitously states mostly have their tip outlay in open months, while wind-powered generators in California are some-more expected to have their tip outlay in summer months.
Monthly solar outlay is tip in a summer months, regardless of location, since of a incomparable series of illumination hours. About half of all utility-scale solar appetite plants in a United States use some form of sun-tracking record to urge their anniversary output.
Based on anniversary patterns in new years, electricity era from breeze and solar will substantially surpass 10% of sum U.S. era again in Apr 2017, afterwards tumble to reduction than 10% in a summer months. Since 2014, when EIA initial began estimating monthly, state-level electricity era from small-scale solar photovoltaic systems, sum breeze and solar era has reached a tip turn in possibly a open or fall. Because these seasons are times of generally low electricity demand, sum breeze and solar era also reached a tip share of a U.S. sum during these times of year.
Based on annual information for 2016, Texas accounted for a largest sum volume of breeze and solar electricity generation. Nearly all of this era was from wind, as Texas generates some-more breeze appetite than any other state. As a share of a state’s sum electricity generation, breeze and solar outlay was tip in Iowa, where breeze and solar done adult 37% of electricity era in 2016. In further to Iowa, breeze and solar supposing during slightest 20% of 2016 electricity era in 6 other states.
In roughly all states, breeze creates adult a incomparable share of a state’s sum electricity era than solar. Among a tip dozen states, usually California and Arizona had some-more solar era than breeze in 2016. Three states in a tip 12—Iowa, Kansas, and North Dakota—had no era from utility-scale solar plants in 2016 and comparatively small outlay from small-scale solar photovoltaic systems.
