In search of ease to generate energy, creativity is something human beings do not lack. Geothermal energy is a way of harnessing energy already present. It uses the heat from the core of the earth as a renewable source of energy.

Standing on the earth, we might ignore the fact that the earth is burning beneath. Geothermal energy is produced by digging into the core of the earth, where this tremendous heat is present and converted into exorbitant power.

Where is the Energy

The core of the earth is very hot, more than 60 times boiling water. Due to the extensive heat, much of the heat can be found pretty close to the surface. There is no need to dig far into the crust and reach the center of the earth to benefit from the energy. Geothermal energy can be harnessed by digging only 3 miles where the temperature is over 100 degree Celsius. At this heat, steam is generated and can be used to produce electricity power.

Typically, we used coal or other fossil fuels to produce electricity for our daily use. However, the same energy can be produced from the heat of the earth. The superheated fluid in the earth is produced from magma a type of molten rock. Thereafter, water leaches into the core of the earth through small lakes and pools. This water, which gets extremely hot beneath the surface of earth is extracted by drilling holes where the water can steam out and power a generator.

The generator is powered by the superheated fluid that generates an immense steam pressure in pipes laid out. The pressure (steam) will assure that a turbine will convert this energy into a kinetic force used to power the generator. The generator will thereafter transform this energy into electricity current that can be fueled into the electricity grid.

Geothermal energy has been a source of energy for several decades. However, it is actually being used less than it could be. There are many reasons why geothermal energy is not making a major breakthrough in the energy sector.

1. Research is Required
It is hard to spot ideal location beneath the earth surface where steam power is present. Much research is required to find a suitable site and to scrutinize that the site will generate energy for a long time.

2. Cost and Hazardous

The cost of establishing a geothermal plant is high. The return is also not assured, as some sites might not be working long-enough to recover investment costs. There are hazardous risks also involved in digging into the crust of the earth. In America, several new regulations have already been presented.

There are however, many positive aspects of geothermal energy as well. The energy does not produce any pollution, as it is natural heat. The energy is also harnessed on a small area. The geothermal power station does not need to be erected on massive areas such as solar panels and wind turbines.

Geothermal energy is expected to expand in the future. However, as precautionary laws are being established in America, proclaiming geothermal drillings relation to earthquakes, the sources of energy might slightly be overlooked. Yet, it is a perfectly viable alternative source of energy.
