Where Does Geothermal Energy Come From?

Geothermal energy comes from beneath the Earth’s surface. Temperatures about 6 feet underground remain consistent throughout the year. This means those underground temperatures are refreshingly cool in the summer and comfortingly warm in the winter. Geothermal energy is a natural and energy-efficient alternative to more traditional energy sources.

How Is Geothermal Energy Harnessed?

Geothermal energy is harnessed through underground liquid-filled loops of piping. The liquid in these loops circulates underground. Massive geothermal power plants use an injection well that sends water underground and a production well feeding into a flash tank for the water that’s pulled up. Smaller systems for home use have a closed loop.

Power plants rely on steam from beneath the Earth to generate electricity. When a geothermal HVAC system is warming the home, it will take cool liquid underground, absorb the heat that’s found there, and bring it back above the surface. When you’re cooling your home with geothermal energy, the loops transport warm water underground where the heat is dispersed. The loops then bring the cooled liquid back into your home where it’s used to create a refreshing chill in your home.

What Types of Geothermal Technology Are Available?

Geothermal energy can be harnessed for mainstream use through geothermal power plants. These plants take steam from deep geothermal reservoirs. This steam then powers generator turbines. The generators create electricity, which can be passed on to the consumer.

Fortunately, you don’t need to have access to electricity from a geothermal power plant to enjoy the energy-efficiency perks of using this energy source. Geothermal HVAC systems operate with a series of loops buried in your yard. These ground loops can be arranged either vertically or horizontally depending on the area that’s available to you. We’ll work with you to determine the best arrangement for your individual situation.

Who Can Use Geothermal Energy?

Geothermal energy is accessible to anyone who has enough space to accommodate the loops that are buried underground. Many homeowners will find they can bring a geothermal HVAC system into their homes. A geothermal HVAC system is extremely effective at helping you maintain your home comfort. You can use a geothermal heat pump for both heating and cooling, so this can replace both your furnace and your air conditioner.

What Are the Benefits of a Geothermal HVAC System?

A geothermal HVAC system is a green alternative to more traditional options, such as a central air conditioner or furnace. A geothermal heat pump uses a more efficient source of energy, so your utility bills will be lower. These systems also require less care and maintenance. They have a longer life span than other options, so you can enjoy your geothermal installation long into the future. The aboveground part of the installation will typically last over 20 years, while the underground loops can last up to 50 years.
