Last year, 42% of new electricity generation capacity in the U.S. came from land-based wind energy — more than from any other source — according to numbers in a series of reports from the Department of Energy (DOE) this week. By contrast, solar amounted to only 38% of new capacity last year.
This measures capacity, which is the maximum amount of electricity that can be produced under ideal conditions, while actual energy generation can be much less than that ideal amount as wind varies.
