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 1.80 MW. However, realistically the wind turbine never runs at full power. If a wind turbine runs at 34.0% capacity for 1.00 year, how much energy does the wind turbine generate? Number E= kWh An average American household consumes 9500 kWh in 1.00 year. How many houses can the one wind turbine power? O 5.1 x 1010 O 100 O 560 O 0.0018 Number of houses =

Explanation / Answer

A) Energy, E = P x t = 1.80 x 106 x 0.34 x 365 x 24 = 1.93 x 1013 J = 5.40 x 106 kWh

B) Number of houses, n = (5.40 x 106)/(9500) = 568 ~ 560 houses.
