How It Works

  1. The Earth’s hot core creates magma and heats the Earth’s crust, which is made up of rocks and water
  2. A well drilled two miles deep into the Earth’s surface captures the rising hot water and steam
  3. The hot steam rises to the surface and pushes a turbine, which rotates a generator
  4. The generator produces electricity and sends it to power lines, which bring electricity to homes and businesses
