If you kept digging, what would you find? You'd probably find lots of worms, roots, and a few dog bones. But if you went really far down, you'd get geothermal energy.

If you take the word geothermal apart, you get "geo" which means earth and "thermal" which means electricity and to heat and cool buildings.

Geothermal Energy - Getting Steamy 1j3s3u
Geothermal power plants use the steam from hot water to produce electricity. The steam rotates a turbine that activates a generator, which produces electricity. There are three types of geothermal power plants:
- Dry Steam - The steam goes directly from underground wells to a power plant. The largest dry steam resource in the world is The Geysers, which is in California.
- Flash Steam - These are the most common. They use reservoirs of water that are hotter than 360 degrees Fahrenheit (182 degrees Celsius). The hot water flows up wells in the ground under its own pressure and some of it turns to steam. This steam is separated from the water and used to turn a turbine.
- Binary Cycle - These plants use water that is about 225 to 360 degrees Fahrenheit (107 to 182 degrees Celsius). The heat from the hot water is used to boil a working fluid (usually an organic compound that boils easily), which vaporizes in a heat exchanger (a device for transferring thermal energy from one fluid to another) and is then used to turn a turbine.

- The US produces the most geothermal energy in the world.
- In the US, geothermal electricity is generated in California, Nevada, Utah, Alaska and Hawaii.
- Unlike solar energy, geothermal resources are available 24/7.
