“…Wind turbines would generate 157 GWh over the same time period and land area. The land at a coal plant is usually unavailable for other purposes, however, whereas only 1-5 percent of the land in a deployment of wind turbines is physically occupied by the equipment itself (Wilshire and Prose 1987). Using the 1 percent figure, we can extrapolate that 15,680 GWh are generated per square kilometer over a period of thirtyfive years for wind.…”
