A school is paying $0.12/kWh for electric power. To reduce its power bill, the school installs a wind turbine with a rated power of 30 kW, which cost $10,000. If

the turbine operates 2200 hours per year at the rated power, determine the amount of electric power generated by the wind turbine and the money saved by the school per year. Calculate the payback time. (10 points)
