A large coal-fired power station produces 2000 MW of electrical energy. A wind turbine with 33 m blades can produce 300 kW.
How many turbines would be needed to replace the power station?
Electrical energy from the power station = 2000 MW = 2000000 kW
Energy produced by the wind turbine = 300 kW
Therefore, number of turbines needed = 2000000/300 = 6666.67
Hence, 6667 turbines will be needed.
