Geothermal energy is another possible source of renewable energy being explored for helping to minimize dependence on fossil fuels.
What is Geothermal Energy?
Though many might not know the name of geothermal energy, this is a readily available energy in the world. This is an energy which uses natural sources much in the same way that ocean energy does. By using the steam or the hot water which is produced in the inner depths of the Earth, electricity is produced. In this process, there are few emissions into the air, allowing it to be a clean and a complete renewable energy source.
To capture the power of geothermal energy, there are several different systems in use right now for energy distribution:
- Deep reservoirs
- Geothermal heat pumps
- Direct use systems
Some areas will collect the hot water produced by the Earth in deep reservoirs where it can be used to be heat up for electricity production again and again.
Geothermal heat pumps are more for space heating and will use the heat created by the Earth to heat buildings and homes.
In many parts of the Western United States, direct use systems are in effect. These systems use wells which utilize the hot water from its source. In doing so, the hot water can be used to heat buildings.
With the many applications for geothermal energy, one can see how useful the energy can be for everyday living and how further exploration for these sources might be a positive way of harnessing the power of renewable energy.
