• Solar• Wind • Geothermal• Hydrogen

Share of Energy Consumed by Major Sectors of the Economy

Energy Consumption in the U.S.1775-1999

WHAT’S PREDICTED

• Supply and demand• Depletion of resources• More cars, larger homes• $$

Ghawar, Saudi Arabia

Cantarell, Mexico

E85 Ethanol•Alternative fuel made from a blend of 85% ethanol and 15% gasoline, derived from corn•Reduces greenhouse gas emissions•GM FlexFuel Vehicles

HYDRO POWER

Hydropower provides about 10% of the electricity in the United States

The United States is the second largest producer of hydropower in the world. Canada is number one

Hydropower is clean. It prevents the burning of 22 billion gallons of oil or 120 million tons of coal each year.

Hydropower does not produce greenhouse gasses or other air pollution. Hydropower leaves behind no waste.

Hydropower plants capture the energy of falling water to generate electricity. A turbine converts the kinetic energy of falling water into mechanical energy. Then a generator converts the mechanical energy from the turbine into electrical energy.
