How much coal goes into a wind turbine? | Debunk House
Sep 12, 2013· Now a coalfired plant has a capacity factor of ~87% and a typical wind turbine only manages ~25%. So it takes about MW of wind power to generate as much electricity as 1 MW of coal power, assuming the wind blows. So, it takes about 1,020 tons of coal to offset 1 MW of coalfired capacity with 1 MW of wind capacity. 1,020 tons of coal would have generated million kWh of .
