Two sites are being considered for wind power generation. on the first site, the wind blows steadily at 7 m/s for 3000 hours per year. On the second site, the wind blows steadily at 10 m/s for 2000 hours per year. The density of air on both sites is 1.25 kg/m^3. Assuming the wind power generation is negligible during other times. a) Calculate the maximum power of the wind on each site, in kW. b) Determine which site is better for wind power generation.
