Question

C) An average household uses about 10,000 kilowatt-hours of electricity annually. How many tons of carbon dioxide would be produced if the household's electricity were generated using only conventional energy sources? a. 2,800,000 b. 1,400,000 c. 700 d. 70 e. 7 D) The production and consumption of electricity are most commonly measured in kilowatt-hours (kWh). A kilowatt-hour is one kilowatt (1,000 watts) of electricity produced or consumed for one hour. A 10-kW wind turbine can generate about 10,000 kWh annually (enough to power a typical household) at a site such as Spirit Lake, Iowa, with wind speeds averaging 12 miles per hour. The 250-kW turbine installed at the elementary school in Spirit Lake provides about ___________ of electricity annually. a. 250 kWh b. 250 mWh c. 2,500 kWh d. 25,000 kWh e. 250,000 kWh
