The traditional sources of energy are generally non renewable and suffer a threat of depletion. This has been evident with deforestation occurring at a very high rate since most of the people have been using wood and charcoal as their source of energy for centuries. If man does not renew this energy source through planting other trees in place of the ones cut, this will be detrimental to the earth since it will destabilize the ecological balance. Coal is also non renewable and so is oil.
This realization has made the world try and look for ways in which it can substitute these traditional sources of energy with the alternative sources. One such source that has been in use for several decades is geothermal energy .Geo stands for earth while thermal stands for heat so geothermal energy is the type of energy that is generated from the earth. For the generation of this energy to be possible, two things are required water and heat.
Excess rainwater seeps down the earth and reaches far down the earth/s surface. The heat that is present in the interior of the earth may sometimes heat this water that has sipped into these interior surfaces of the earth and if this water that is heated finds its way to the surface of the earth through fissures, it may be in form of steam or hot water.
The energy from this heated water or steam is the one that will be used to drive a turbine which will in turn spin the generator to produce energy.
This energy from the earth is referred to as a natural source of energy since both the heat from the earth and the water from the rain is naturally occurring. Water is naturally renewed by the rain and the heat from the earth is naturally renewed by being continuously produced from the earths interior.
The world is being continuously encouraged to use this type of geothermal alternative energy in a bid to reduce the pollution that occurs from the use of the other non renewable sources of energy and also for the reduction of production of greenhouse gases.
When the generation of geothermal energy is done in the right manner, it gives clean energy free from any pollutants. Although the initial investment of constructing a geothermal power plant is high, the returns are quite high also since it is self sustaining and it does not require a lot of money to operate it.
