From the inside out…

Geothermal energy is created using heat from the Earth’s core.

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
