Is Geothermal Energy Worth the Price?

The rise in energy costs gives homeowners the opportunity to explore alternative heating and cooling systems. The geothermal heat pump is a viable option. Despite the high cost of geothermal heat pumps, their efficiency and reliability provide a value that can restore high installation costs. The great advantage provided by this system will overcome the additional costs. The geothermal heat pump differs from other heat pumps in that it uses geothermal instead of extracting heat from the air.

Geothermal energy is the heat generated and stored on the earth. Thermal energy is the energy that determines the temperature of a substance. Geothermal energy of the Earth's crust arises from the primitive formation of the planet and the radioactive collapse of the material (now uncertain, but probably nearly equal). The geothermal gradient, the temperature difference between the center of the planet and its surface, promotes the continuous conduction of thermal energy in the form of heat from the center to the surface. The geothermal of the adjective comes from the Greek root γη (ge) meaning earth and θερμος (thermos) meaning heat.

Before raising profits, you first need to understand geothermal energy. Geothermal is a combination of two words. Geography means the earth, heat means heat. Therefore, geothermal energy generates energy using the heat inside the crust. More specifically, geothermal energy uses water that generates water vapor in the crust. This steam is used to turn the turbine to generate electricity. Geothermal energy actually uses a process that produces energy similar to coal and natural gas. However, it avoids the need to burn fossil fuels to produce steam by using steam in hot water found in the Earth's crust. This makes geothermal energy clean and reproducible. Also, unlike intermittent renewable energy such as wind power and sunlight, geothermal energy is stable, it is an excellent base load generator.

Geothermal energy is not exhausted like petroleum and natural gas deposits. Since prehistoric times, many hot springs in the world are drinking warm water and steam. Therefore, geothermal energy is regarded as a form of renewable energy production, and in our own era, we benefit from "production tax deduction" on renewable energy. This tax deduction has been extended by the US Congress until 2008 and is expected to expand further in the future. With production tax deduction and five year depreciation plan, the US government effectively subsidizes 63% of the capital cost of renewable energy project. Therefore, renewable energy projects, especially geothermal projects, are beneficiaries of major investment tax deductions.
