How Much Energy Does A Wind Turbine Produce?

Your electricity bill is based on how much energy you use: if you look at the bill you will be charged per kWh (short for kilowatt-hour) you use. Energy is power multiplied by time. The units of power are watts, and units of energy watt-hours. For example, if a turbine runs for 1 hour at 1000W, it will generate 1000 watt-hours of energy.
