A single wind turbine has a maximum power output of 2 000 000 W. The wind turbine operated continuously at maximum power for 6 hours. Calculate the energy output in kilowatt-hours of the wind turbine.

Equation:P = Wt (Power = Work[Energy] x time)1) Convert Watts to Kilowatts (W -> kW)2,000,000W -> 2,000kW [divide by 1000]2) Multiply work by time (remembering the question asks for kWh)2,000kW x 6h = 12,000 kWh
