The local population is strongly against the AI company installing CO2 emitting gas turbines in their community. They want wind turbines with battery storage utilized instead. Consequently, your boss has asked you to determine the power output (in kW) from a twin-blade wind turbine having the following specifications: blade length of 15.6 m and overall turbine efficiency of [eff]%, and experiencing an average wind speed of 12.5 km/h and air density of 1.112 kg/m3.
