- Nonrenewable fuels are called fossil
fuels because they were made millions of years ago from the remains
of animals and other organic matter that was under large amounts
of heat and pressure.
- Fossil fuels are depleted at a rate
that is 100,000 times faster than they are formed.
- Only 6 percent of total U.S. energy
consumption came from renewable sources in 2003. Of that total,
94 percent was from hydropower and biomass.
- Wind power is the fastest growing
energy source in the world.
- Wind power has the potential to supply
20% of U.S. electricity demand at an economical price.
- Geothermal energy comes from heat
that is under pressure inside of the earth and is tapped for space
heating and power production.
- Solar technology uses energy from
the sun and converts it into electricity using photovoltaic cells.
Solar works best in areas that receive large amounts of sunshine.
- Hydropower creates electricity by
converting kinetic energy from falling water into electric energy.
- Fossil fuels provide about 80% of
total global energy production and consumption.
- Natural gas is the cleanest burning
fossil fuel.
