Hundreds of Thousands of Wind Turbines Power Farms in the U.S.

Circa 1930 to 1945

"In the 1930s and 1940s, hundreds of thousands of electricity-producing wind turbines were built in the U.S. Just like wind turbines today, they had two or three thin blades, which rotated at high speeds to drive electrical generators. These wind turbines provided electricity to farms beyond the reach of power lines and were typically used to charge storage batteries, operate radios and power a few lights" (Michigan renewable energy, accessed 04-20-2009).
