  • Geothermal Energy - National Geographic Society
    Geothermal energy is renewable; it is not a fossil fuel that will be eventually used up Earth is continuously radiating heat out from its core, and will continue to do so for billions of years Some form of geothermal energy can be accessed and harvested anywhere in the world Using geothermal energy is relatively clean
  • Renewable Energy Explained - Education
    Geothermal: Used for thousands of years in some countries for cooking and heating, geothermal energy is derived from Earth’s internal heat On a large scale, underground reservoirs of steam and hot water can be tapped through wells that can go a two kilometers deep or more to generate electricity
  • geothermal energy - National Geographic Society
    Geothermal energy can be used to heat structures such as buildings, parking lots, and sidewalks Most of the Earth’s geothermal energy does not bubble out as magma, water, or steam
  • Hydroelectric Energy - National Geographic Society
    Hydroelectric energy, also called hydroelectric power or hydroelectricity, is a form of energy that harnesses the power of water in motion—such as water flowing over a waterfall—to generate electricity People have used this force for millennia
  • Renewable Resources - National Geographic Society
    Geothermal energy comes from the heat generated deep within Earth’s core Geothermal reservoirs can be found at tectonic plate boundaries near volcanic activity or deep underground Geothermal energy can be harnessed by drilling wells to pump hot water or steam to a power plant
  • Renewable Energy - Education
    Geothermal energy can melt underground rocks into magma and cause the magma to bubble to the surface as lava Geothermal energy can also heat underground sources of water and force it to spew out from the surface
  • Fossil Fuels - National Geographic Society
    This is the energy that is used to heat and provide electricity to homes and businesses and to run cars and factories Unfortunately, fossil fuels are a nonrenewable resource and waiting millions of years for new coal, oil, and natural gas deposits to form is not a realistic solution
