How geothermal power stations work
turbine / generator / heated / water / evaporates / homes
- In regions with lots of volcanic activity, the ground is naturally very hot.
- So when we pump cold down into the ground it will be by the hot rocks.
- If we pump this hot water back up to the surface we can use it to heat our .
- Alternatively, we let it heat up so much that it into steam.
- The steam can then be used to turn a , which in turn can drive a to produce electricity.
