1. Is geothermal energy considered a renewable energy? Why?

      Yes. Geothermal energy is drawn from the earth's internal heat, which does not change or run out like non-renewable sources of energy, such as oil and coal.

    2. What country generates the most geothermal energy?

      The United States 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?

      The pipeline is so well-insulated that the water only loses 1.8° Celsius (3.2 degrees Fahrenheit) on its journey.

    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?

      Possible response: You can use solar or wind power to pump the warm water to the town.

    • 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 the 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.
