The Many Uses of Geothermal Energy

It’s Used for More Than You Think

Today, the use of geothermal energy is growing in a wide variety of industries, and is used for many more processes and applications than you may think. Here are some of the most popular:

In Homes

One of the most common uses for geothermal energy is heat and air conditioning for homes. With a geothermal installation, your system can collect hot air from inside your home, send it down through pipes that are in the ground, and bring it back up as cold air. This process can also be reversed in the winter, and uses no fossil fuels.

Geothermal energy (in the form of a heat pump) can also be used to heat the water that you use for showers, laundry, dishes, and more.

For Farming

Many fruits, vegetables, flowers, and herbs are grown in greenhouses, and farmers around the world rely on geothermal energy to keep them at an optimal growing temperature. This comes in especially handy during cold winter months.

It’s also used for fish farming in places like Oregon, Idaho, Japan, and China. When the water is warm, it promotes the growth of several different types of fish.

When it comes to milk, pasteurization must be done at a high temperature in order to prevent bacterial growth. Many farmers use geothermal energy to heat the milk for pasteurization and then cool it back down for packaging.

Drying Processes

Many food and agricultural industries use geothermal drying processes to dry and preserve a wide variety of foods, from fruits to meats to herbs and more. Companies use a heat exchanger that circulates geothermal hot water or steam in order to dry the foods and remove moisture.

Timber mills also use geothermal energy to dry their wood. Once a piece of wood is cut, it must go through a drying process in order to set the sap and prevent it from warping in the future. Instead of using steam from boilers, many companies use geothermal energy to save money.

Other Uses

There are many other industries where geothermal energy comes in handy, such as:

  • Pulp and paper processing
  • Soft drink carbonation
  • Fabric dying
  • Cement and aggregate drying
  • Ethanol and biofuel production
  • Snow melting and de-icing
