Geothermal Energy – Untapped Unlimited Renewable Energy From The Earth

Abhishek Agarwal asked:

With people looking for more and more ways to find renewable sources, many don’t realize they are standing on top of one of the greatest resources on the planet. The Earth’s core is at an unbearable temperature, hotter than anyone could possibly even fathom. This heat builds up so much pressure in the Earth’s core that it has to be released in some way. These releases are known as geothermal . The hot water and steam from the Earth can be used in a number of ways to create energy. This is a renewable energy because the heat in the Earth’s core is constant and the water replenishes from .

There are different ways to use geothermal energy that include direct and indirect uses.

– The heat from the Earth could be used as a for heating systems. The hot water close to the Earth’s system is directly pumped into heating systems.

– Generators in power plants require steam at very high temperatures to work. Geothermal power plants are built near reservoirs to tap the natural resource. The power plants use steam or water close to the surface to operate its generator.

– Geothermal heat pumps use water near the Earth’s surface to control building temperatures. This renewable energy source can regulate entire towns and villages.

Using geothermal energy isn’t a new concept. History has shown that people in ancient times have used hot springs for cooking, bathing and heating purposes. Even today many believe that natural hot springs have healing powers. There are many people who still bathe in hot springs. In Reykjavik, Iceland 95 percent of the buildings are heated with geothermal district heating systems. Hot water near the Earth’s surface is pumped directly into the buildings.

The Unites States is one of the leaders in geothermal power. The country has more geothermal power plants than any other, however, it only accounts for one percent of the electricity produced in the U.S. California (33), Nevada (15), Hawaii (1) and Utah (1) are the only states with geothermal power plants.

There are opponents of geothermal energy. While there are uses for it, criticisms have been raised. Some believe this is not a long term solution nor could it be used in huge environments. There are others who think creating geothermal power plants would cost too much money and drain money from researching other valuable energy resources. People are also concerned that if magma is tapped, it could bring up dangerous and harmful particles.

One thing is certain, more research is needed to make an educated conclusion about geothermal energy. There is too much guessing going on and not enough doing. There are results of natural geothermal reactions. These happen everywhere and come in the form of volcanoes, hot springs and geysers. With geothermal reactions occurring naturally, humans should find a safe way to tap into it.
