WebSep 20, 2011 · The short answer is that if they move slowly, they produce less power. But if the wind speed doubles, then a windmill could produce eight times more power under the appropriate conditions. If there is too little wind and the blades are moving too slowly, the wind turbine no longer produces electricity.
