    Assume a wind turbine with a hub 50 meters above the ground, a rotor diameter of 40 meters and a wind-conversion efficiency of 25 percent. The turbine operates in an area with an average wind-power density of 550 watts/sq meter at 50 meters altitude. How much electricity (kwH) can the turbine generate per year?

    Wind densities greater than or equal to 500 watts/sq meter at an altitude of 50 meters are present on 0.900 percent of the land area of the US. If, on average, wind farms contain 8 turbines/sq km, how much electricity (kwH/yr) could be generated from these wind turbines? (The area of the US is 7,827, 989 sq km).

    Solution Summary

    The solution shows how dimensional analysis may be used to convert wind-power data into kWh of electricity produced by a wind turbine. The result is the number of kWh generated in a year by the turbine.
    In the second part, the total amount of electricity created by many such turbines in a certain area of the US is calculated. All calculations are shown and explained.
