With 73,992 MW, the US is now the no. 2 country in the world in installed wind capacity (after China, which has a mind-boggling 145,053 MW). And we are no. 1 in actual wind electricity generated.
All that wind only provides about 5.6 percent of US electricity, though, which puts us well behind leaders like Denmark (40 percent), Portugal, Ireland, and Spain (between 20 and 30 percent).
