What is the commercial viability of geothermal energy?
Advantages Geothermal energy does not produce any pollution, and does not contribute to the greenhouse effect. The power stations do not take up much room, so there is not much impact on the environment. No fuel is needed. Once you’ve built a geothermal power station, the energy is almost free. It may need a little energy to run a pump, but this can be taken from the energy being generated.
