Don Quixote would be proud. Humans have been harvesting wind power for centuries, but the growing desire for renewable energy means we're building wind farms on an unprecedented scale, giving the knight-errant more wind mills than he could ever tilt at.
The last decade has seen $128 billion in new wind project investment in the U.S., with 20 states last year adding nearly 8,600 megawatts of capacity, a 77 percent increase over 2014, according to the American Wind Energy Association. That represented 41 percent of all new electricity generation capacity to come online during the year, surpassing solar and natural gas, the industry lobbying group says.
