Geothermal power

Wednesday, July 8th, 2009

A large number of renewable energy sources and conventional energy sources are used that can generate power to meet the energy requirements of the world. The traditional sources of energy like coal and fossil fuels have been used to generate power for a long time. But the use of these sources has increased pollution and created a lot of health hazards for the living beings. Because these sources are non renewable energy sources, they cannot continue generating power for a very long time as their reserves are depleting everyday. So the need of an alternative power source arises to meet the energy requirements.

Geothermal power can be considered as a possible alternative energy source that can generate enough power to meet the energy needs of the entire world for a very long time. Earth power is the useful form of energy obtained from geothermal energy. The energy is generally in the form of electricity. Geothermal power can be harnessed from the earth’s core that is very hot and heats water and turns that is converted it into steam. This steam as a geothermal power product can then be used to run turbines which are connected to generators that convert the steam into geothermal power or electricity.

To harness geothermal power products, a well needs to be drilled into the earth’s surface to reach the geothermal reservoir. Once the geothermal reservoir is trapped, the geothermal power products like hot water or steam can rise to the surface and can be used to produce electricity.

Geothermal Earth Power Products & Cooling Systems

The geothermal energy or the earth energy can be put to several uses. By using proper techniques, it can be converted to useful electrical energy called geothermal power. Geothermal power can be used in various applications.

One common application of earth power is the geothermal cooling system. The geothermal cooling system uses the fact that the ground remains cooler than the surrounding atmosphere during summers and it remains warmer than the surrounding atmosphere during winters. This keeps the buildings cool during summers.

It is important to understand that geothermal cooling systems do not produce heat or cold as geothermal power products. They function to transfer heat from one place to another. Such a system consists of pipes, delivery system and a heat exchanger unit. The heat exchanger unit is installed in ground near the building and transfer heat. During a hot summer day, a refrigerant or water flows through the system into the earth through pipes. In the depths of the earth, the water is cooled and then transferred back to the delivery system. The cool water circulates through the home and absorbs the heat causing it to get heated and is then transferred back into the ground for cooling. This is the simplest configuration of such a system. Changing and improving technologies have helped in developing systems that can work efficiently.

The use of cooling systems that work on earth power can help to reduce the electricity bills by a significant amount. Geothermal power used in these systems is a renewable energy source and will always be available.
