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 1.00 MW. However, realistically the wind turbine never runs at full power. If a wind turbine runs at 33.0% capacity for 1.00 year, how much energy does the wind turbine generate? An average American household consumes 1.00 x 10^4 kWh in 1.00 year. How many houses can the one wind turbine power?

Explanation / Answer

Energy(E)= (33*106/100 )*3600*24*365 ;but kWh=3.6 x 106 J so divide by this

E= 2890.8 kWh

number of houses= E/(104) =0.289
