For a 45m diameter, 850kW wind mill, if the cut in speed is 4.2m/s, cut?out speed is 22.5m/s and
wind energy was generated from wind speeds ranging from 5.2 to 20.5m/s, calculate

a) The total number of hours that wind energy could be generated?
b) The total number of hours that wind energy could not be generated?
c) the total annual wind energy produced.
d) Assuming average power consumption of a typical Midwest family is 2.35kW, how many families could be served by this facility?
e) If it costs 6.2 cents to industry and 18.8 cents to residential customers, and it costs $1550 per
kW for the generation of wind energy, determine how long it takes to pay back in each case.

2) Calculate the area of land required by wind farms to provide 1
3) 2% of 500TWh per year, using 5MW wind turbines
