Study Notes

Overview of Renewable Energy Sources

  • The United States relies on nonrenewable sources of energy like coal, oil, and natural gas, but also uses renewable resources for energy.
  • Renewable energy comes from widely available and quickly regenerating resources that can be used repeatedly without depletion.
  • Renewable energy can be used to generate electricity, power air and water heating and cooling, vehicles, and systems outside of cities.
  • Wind energy can be collected through windmills and turbines, with turbines converting wind energy into electricity.
  • Wind energy is a renewable resource, but turbines can harm wildlife and only supply about 5% of the world's needed electricity.
  • Hydroelectric power is mostly produced by dams, which harness the power of water to generate electricity.
  • Dams impact fisheries and wildlife in rivers and can cause a loss of habitat for many types of wildlife.
  • Hydropower can also be generated from ocean waves and tides but can disrupt ocean life and habitats.
  • Solar energy is created when sunlight is converted into electricity through solar panels, but installation is expensive and solar energy collection is limited by weather conditions.
  • Biofuel is a fuel made from biomass, which is material from living or recently living things, and is a clean fuel source for transportation but does not generate a lot of energy.
  • Geothermal energy is heat produced deep inside the Earth that can be captured through power plants or heat pumps, but is expensive and can trigger earthquakes.
  • Geothermal energy is renewable and environmentally friendly, but only available in specific locations.

  • Geothermal energy is heat produced deep inside the Earth, which can be captured through geothermal power plants and heat pumps, but is expensive to capture and not available everywhere.
  • Renewable energy is important for reducing dependence on nonrenewable energy sources such as coal, oil, and natural gas.
  • Wind energy supplies only about 5% of the world's electricity needs.
  • Scientists estimate that the amount of solar energy received by the Earth in one day is enough to supply current energy needs for 30 years.
  • Renewable energy sources have varying degrees of impact on the environment and wildlife, and their use should be carefully considered.
