How can geothermal energy be used in the future?

The word geothermal comes from the Greek words geo (earth) and therme (heat). So, geothermal energy is heat from within the earth. We can use the steam and hot water produced inside the earth to heat buildings or generate electricity. Geothermal energy is a renewable energy source because the water is replenished by rainfall and the heat is continuosly produced inside the earth.

Geothermal energy can be used in the future as an alternative to fossil fuels and coal. It is a good source of energy because it does not cause pollution, and there is obviously a constant supply of it. This means that prices for geothermal energy will be consistent, unlike oil.
However, it is a hard technology to master, and can only be used in parts of the world where there is enough heat in the earth (think hotspots or underwater volcanoes). I think some of the Scandinavian countries are using geothermal energy.
Other renewable energy sources include hydropower, wind-power, solar power or nuclear power.
