Question

A challenge gaining prominence throughout the planet is the increased need for "green" or sustainable energy. In certain parts of the country, wind farms are a viable alternative to conventional energy sources. An average wind turbine (the device which converts rotational motion to electricity) has a maximum capacity of 2.00 MW. However, realistically the wind turbine never runs at full power. If a wind turbine runs at 31.0% capacity for 1.00 year, how much energy does the wind turbine generate?

Explanation / Answer

effective energy=2*0.31

=0.62 MW

so energy=0.62x106*365*24*60*60

= 1.955x1013J

Energy=5.43x106 kW hr
