US renewable electricity grew to 19.7% of total installed capacity and 17.7% of total electricity generation in 2017, compared to 18.3% of total installed capacity and 15.6% of total electricity generation in 2016 according to the 2017 Renewable Energy Data Book, now in its 10th edition. Installed global renewable electricity capacity also continued to increase in 2017, representing 32.2% of total capacity worldwide.
In 2017, renewable electricity accounted for 60% of US electricity capacity additions, compared to 67% in 2016. U.S. wind capacity increased by more than 8.3% (6.8GW) compared to 2016, accounting for more than 43% of renewable electricity capacity installed. Wind represented 7.5% of cumulative U.S. installed electrical capacity in 2017.
The Renewable Energy Data Book presents US and global energy statistics compiled from numerous data sources and includes renewable electricity generation, renewable energy development, clean energy investments, and technology-specific data. This year’s edition is the first to include data and trends for electric vehicles and energy storage technologies, in addition to data-centric charts for wind, solar, hydropower, and alternative fuels. The Renewable Energy Data Book also includes state- and region-specific energy data and trends, along with statistics on clean energy investments and development worldwide.
