Wind and solar produce 8% of US generation in 2017

UNITED STATES: Wind and solar PV reached or exceeded 20% of total generation in ten states in 2017, according to figures from the Energy Information Administration (EIA).

Combined, the two technologies generated 8% of total US output last year, the EIA’s figures showed.

Of the ten states with the highest share of wind and solar generation, almost all of them are driven by wind power, EIA analyst Cara Marcy noted.

In eight of the top ten states, wind generated more than solar (EIA)

For example, of the 37% penetration achieved by the two technologies in Iowa — which topped the EIA’s list — 36.8% came from wind and 0.2% from solar.

However, in some states, such as California, Nevada, Massachusetts and Arizona, solar generation was higher than wind output.

During some months, wind accounted for more than half of in-state generation in Iowa and Kansas — the two states in which wind and solar provided the highest share of production.

Iowa (7.2GW), Oklahoma (7.0GW), California (5.7GW) and Kansas (5.3GW), which respectively had the second, third and fourth most installed wind capacity by the end of 2017, all made the top ten.

Texas (22.1GW), which had the most in the US at the end of last year, did not.
