Question

Dresden, Germany has a population of 700,000 and a population density of
2200 km-2 in the urban area. Assume that the electrical needs of Dresden are an average of
1.0 kWe per capita and these are satisfied by a wind farm consisting of 100 m diameter
three-rotor wind turbines operating at optimal efficiency and with optimal spacing. If the
wind velocity is constant at 7 m/s, what is the area of the wind farm? The optimal efficiency, η = 0.49 and 
The ideal spacing for a turbine is 300m by 1000 meters 

Answer in km2
