Read on to know what geothermal energy is and what its effects are on the environment.
Geothermal energy is the heat generated from the Earth. Geo means solid part of the Earth and thermal means heat energy. Harness the heat into the form of energy found at volcanic activity is close to Earth under its surface. Geothermal energy is produced inside the Earth under the surface of it. The twin-layered core is made up of extremely hot molten rock occupying a solid iron center. Very high temperatures are constantly produced inside the Earth by the slow decompose of radioactive particles.
Geothermal energy technologies make use of the heat for geothermal heat pumps, direct-use applications and electrical power production. Resources of geothermal energy differ from the low ground to hot water and hot rock beneath the Earth’s surface, even deeper to the tremendously elevated temperatures of molten rock called magma.
What is geothermal energy?
Geothermal energy is the heat generated from the Earth. Energy produced inside the Earth under the surface of it. The twin-layered core is made up of extremely hot molten rock occupying a solid iron center. Very high temperatures are constantly produced inside the Earth by the slow decompose of radioactive particles.
Geothermal energy was used by ancient people for bathing and heating. Presently hot springs are being used for bathing and many people believe they have natural healing powers. Using geothermal energy to produce power is a new industry.
Fluids extracted from earth hold a combination of gases mainly carbon dioxide, hydrogen sulfide, methane and ammonia. These pollutants add to global warming, acid rain, and noxious smells if released. Present geothermal electric plants release carbon dioxide of electricity, a small portion of the emission intensity of conventional fossil fuel plants. Plants with high levels of acids and volatile chemicals are usually prepared with emission-control systems to decrease the exhaust.
Hot water from geothermal resource may hold in solution trace amounts of harmful elements such as arsenic, mercury, boron, and antimony. These chemicals precipitate as the water cools and can be a reason for environmental damage if released.
Direct geothermal heating systems contain compressors and pumps, which may consume energy from polluting source. This load is normally a portion of the heat output polluting less than electric heating. The electricity is formed by burning fossil fuels and then the emissions of geothermal heating may be similar to directly burning the fuel for heat.
Geothermal has minimum land and freshwater necessities. It generates almost no emissions as they do not burn fuel to produce electricity.
