Renewable vs. Nonrenewable Energy
  • 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.
