Geothermal Power | Geothermal Energy

Geothermal power is energy generated by heat stored beneath the Earth's surface or the collection of absorbed heat in the atmosphere and oceans. Geothermal energy offers a number of advantages over traditional fossil fuel based sources. From an environmental outlook, the energy harnessed is clean and safe. It is also viable because the hot water used in the geothermal process can be re-injected into the ground to produce more steam. In addition, geothermal power plants are unaffected by the change in weather conditions. Geothermal energy uses steam or hot water in the earth's crust to power turbines or to heat buildings or water. The earth's crust contains a large amount of energy. Hot water from within the earth can heat buildings with no conversion. Geothermal earth energy can provide heating in winter, cooling in summer, and year-round hot water for home use.

Geothermal power stations are able to provide an excellent source of; clean, cheap, simple, renewable power. Geothermal energy is one of the best natural energies around.

No fuel is used to generate the power which means the running costs for the plants are very low as there are no costs for purchasing, transporting, or cleaning up of fuels that are used to generate the power. Heating and cooling buildings using geothermal energy is the primary use of the Earth's heat energy. Much energy is placed into moderating the temperature inside buildings, especially during times of extreme heat or cold. Using geothermal energy as a way of controlling temperatures in buildings is one way to continue to provide that comfort but reduce the use of energy sources that are more harmful to our atmosphere. Geothermal energy is effectively a renewable resource that does not consume any fuel or produce significant emissions. Geothermal energy is renewable, and the energy source itself is currently free.

To utilize this energy, however, there are capital and operating costs that have to be taken into account. The capital costs are generally somewhat higher than conventional heating systems, but the operating costs are usually significantly lower. Another disadvantage of geothermal heat is that it is extracted from deep within the earths surface, and it is difficult finding a suitable build location. However, geothermal energy is something we need to utilize more in order to lesson the impact on global warming.

Renewable Energy

Renewable energy effectively uses natural resources such as sunlight, wind, rain, tides and geothermal heat, which are naturally replenished. Renewable energy technologies range from solar power, wind power, hydroelectricity, micro hydro, biomass and biofuels for transportation.
