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.
