2. A wind turbine with a blade-length of 45 m is producing 3 GWh annually. It is located in an area with a mean temperature of 6.8°C. (a) Assuming the wind speed distribution is constant over the year, calculate the wind speed for a turbine efficiency of 70% with respect to the maximum theoretically possible efficiency.. (b) Consider now a realistic wind speed distribution following the Rayleigh distribution. Which average wind speed would lead to an equivalent average power output as in (a). Hint: The Rayleigh distribution is given by:
