Abstract
The United States faces energy shortages and increasing energy prices within the next few decades (Duncan 2001). Coal, petroleum, natural gas, and other mined fuels provide 75% of US electricity and 93% of other US energy needs (USBC 2001). On average, every year each American uses about 93,000 kilowatt-hours (kWh), equivalent to 8000 liters of oil, for all purposes, including transportation, heating, and cooling (USBC 2001). About 12 kWh (one liter of gasoline) costs as much as $0.50, and this cost is projected to increase significantly in the next decade (Schumer 2001).Keywords
