1. Read the Fast Facts first!

    Is geothermal energy considered a renewable energy? Why?

  2. What country generates the most geothermal energy?

  3. How much heat is lost as the water moves through the pipeline from the geothermal power station to Reykjavik? Why?

  4. Imagine that you run a geothermal power plant like the Nesjavellir Power Plant. You want to make the plant more environmentally friendly. What are some other ways you can use renewable energies to make the plant more environmentally sound?

  • Geothermal energy is extracted from within the Earth. Magma heats up rocks and water in the crust. The heated water and steam from the rocks then make their way to Earth's surface.
  • Renewable energies are power sources that won't run out.
  • Geothermal heat is a renewable energy because it is continually being produced in the Earth.
  • The United States generates more geothermal energy than any other country.
