Geothermal energy uses hot water found naturally underground or artificially injected into rock reservoirs to generate electricity in power plants. While it produces clean energy, geothermal reservoirs only last 15 years to regenerate, making it not truly renewable. The technology can also be expensive, but Iceland benefits from large geothermal reservoirs that allow electricity production to be profitable.

- 1. Geothermal plant in Iceland Geothermal energy
- 2. What is it? Geothermal energy is clean energy, but it isn’t renewable, because the thermal energy of reservoirs doesn’t last more than 15 years, but takes millions to regenerate. It proceeds from heat stored below the surface of the earth, which comes up the surface in volcanic areas.
- 3. How does it work? Geothermal energy plants use hot water to generate electricity. This water can either be found naturally in hydrothermal and geopressurized, or is artificially injected in rock reservoirs.
- 4. Disadvantages Negative environmental impact . Expensive technology. Advantages There are huge geothermal reservoirs. Producing electricity in this manner is profitable.
