Geothermal energy advantages and disadvantages

Let us see the introduction about Geothermal Wind Energy. Geothermal energy is used to store the heat in the earth and it extracted the power from earth. The motion of the wind is converted into mechanical energy by rotating the wind turbine also called wind mill, which is used to produce electricity.


Geothermal heat pumps have several advantages and disadvantages. Which geothermal system is right for a given installation, or even whether to use a geothermal system, depends on the circumstances of that particular installation.

Geothermal energy advantages and disadvantages

  • Geothermal energy is used for the home appliances and heat is taken from the earth.
  • In both commercial and residential installations, geothermal heat pump systems typically have lower maintenance costs than conventional systems as all equipment is installed inside the building or underground. This means that there is no outside equipment exposed to weather and vandalism. All refrigerant systems are sealed, similar to household refrigerators.

  • Wind energy is freely available and inexhaustible.
  • Geothermal wind energy power production cost is low.
  • No consumption of fuel and hence no fuel cost and transportation problems.

Disadvantages of Geothermal Energy:

  • Wind energy is not continuously available and fluctuating in nature.
  • Noisy in operation.
  • Geothermal systems tend to have a somewhat higher first cost than conventional systems. Open-loop systems have more potential problems than either conventional systems or closed-loop geothermal systems because they bring outside water into the unit. This can lead to clogging, mineral deposits, and corrosion in the system.
  • Large land area is required.

These are advantages and disadvantages of geothermal energy.
