Early Wind Power

From the National Renewable Energy Laboratory (NREL):

On a hilltop in Rutland, Vermont, Grandpa's Knob wind generator supplied power to the local grid during World War II. The Smith-Putnam machine was the world's first megawatt-scale wind turbine, rated at 1.25 MW in 30 MPH wind speeds. It was removed from service in 1945. #TBT
