How does Geothermal Energy work?
a summary
Diagram of how geothermal works
- Cold water is pumped beneath the earth's crust.
- The heat from magma and molten rock in the center of the earth heats up the water.
- The water, now hot, is pumped back up into the geothermal power plant.
- This heat can then be converted into energy, or pumped directly into offices and homes.
