An investment cost for the wind power system is RM 5000 with the annual maintenance costs are RM 200. If the annual energy output of a connected wind turbine with a diameter of 30 m, a hub height of 95 m. Reported that its annual energy output is equal to 400 kWh at the average wind speed is 7.5 m/s. Calculate the efficiency of the built turbine if the air density is equal to 0.602 kg/m³. Also, by assuming that the average price the wind turbine owner pays to utility is RM 25 ct/kWh, and by considering that a technical life time of the wind turbine is 20 years, calculate the loss or profit of the wind power system.
