Alternative Energy – Geothermal Energy

Keeping in view the importance of geothermal energy we shall put all efforts to cultivate geothermal energy techniques. This is a field which has marvelous growth opportunities and it simply harvests the natural energy present under the surface of our planet Earth. There are huge reserves of geothermal energy under the surface of earth. What we have to do is go for it and connect to pipe it up.

The Science of Geothermal Energy

The temperature at centre of our planet the Earth is more than 60 times greater than the boiling point of water. Such a huge temperature generates massive pressure deep under the surface of earth. The vast pressure contains immense quantity of energy in the form of heat and pressure. The pressure so generated develops channels to come out of surface of earth. We can observe this energy when hot fluids called magma flare-up from volcanoes. The idea of geothermal energy is to convert this energy into electricity which we can use for our domestic and industrial consumption. A vast quantity of magma is present deep under the surface of earth. We have to locate such sites where the deposits of magma are large enough to run our project economically. Than we have to develop the channels to release underground pressure. Erect a power generation plant and produce power.

Criticism over Geothermal Energy

There is a group of opponents who strongly argue against the industrial harvesting of geothermal energy. They claim that it is costly and time consuming to locate a site where huge deposits of underground magma are present. They claim, even the site located for a geothermal plant, may not be magma-rich enough to produce the energy for a long period. Such a situation may lead towards project failure. Some preservationists claim that sucking magma up from the depth of earth surface may transport up some damaging elements.

Benefits of Geothermal Energy

The advantages of geothermal energy are huge enough that the loud of opponents can easily be undermined. The major advantage of geothermal is that it is the energy of our planet itself and it cannot harm its own environment.  It is highly resourceful energy. Once we have pointed out the site, bored the pipes in to give way to the underground pressure and erected the plant, there is no further cost. Geothermal plants, when compared with other energy producing plants like hydro power plants and nuclear energy plants occupy lesser space. Another important advantage of geothermal plant is that our reliance over fossil fuels to cater our energy needs would be reduced. The final and the most important advantage is the underground reserve of geothermal power is not going to deplete. The sum of all the advantages could be concluded that power generation using geothermal energy would be far cheaper.
