Top 5 Advantages of Geothermal Energy


There’s plenty of room for improvement in the way we heat and cool our homes.

It might be easy to stick with what you’ve always known, but wouldn’t you like to know if there were a better way of doing things?

Though the prospect of switching to a different heating and cooling system might seem intimidating, more and more people are finding that it’s worth the curiosity as energy rates for gas and oil continue to rise.

Geothermal heating and cooling is one such “better way” for several reasons. Plus, choosing geothermal energy is easier than ever before. Here are the top five advantages of geothermal energy.

1. Geothermal energy is reliable and widely available

When it comes to making sure you and your family are warm and safe during the cold winter months, or cool and comfortable in the heat of summer, you don’t want to bet on anything you can’t count on.

Geothermal energy is capable of producing energy day or night and regardless of weather conditions. It has all the stability and “there for you” value of the earth you walk on – quite literally! Ground-source heat pumps, in particular, are safely tucked away from weather, which makes them ultra-reliable.

There are very few nuts and bolts tying the whole system together; a secure loop of underground pipes collects the earth’s heat energy and sends it to a heat pump inside your home. The heat pump circulates a heat-conducting fluid in the pipes and distributes the warm air it produces through your duct system.

Since all this happens underground or inside your home, the bits and pieces of the geothermal system are protected from the elements. That means a drastic reduction in damage or mishaps with the moving parts.

Geothermal is also available to homeowners all across the U.S. because the earth maintains a fairly consistent temperature of about 55 degrees Fahrenheit just 10 feet below the surface.

Newer methods of designing and installing geothermal systems also make them far easier and less expensive to install for homeowners, and thus are more widely available to more people.

2. Geothermal energy provides heating AND cooling

So, you understand how the ground loop system and heat pump for a geothermal system can capture and circulate heat from the earth, but how is it able to cool a home as well?

To put this succinctly, the geothermal system works in reverse to cool a home. Rather than collecting heat energy from underground and sending it to the heat pump for a boost and distribution through your air ducts, heat is removed from your home on hot days. 

The hot air in your house is collected by your air ducts and sent to the heat pump, which ships it off to the ground loop system. When it arrives underground, the heat is dispelled into the earth safely and efficiently.

This leaves you with a cool house and low humidity indoors. It’s an easy, intuitive way to enjoy natural air conditioning at home.

3. Geothermal energy pays for itself

Home geothermal systems are as local as it gets. They generate energy at your house and cut down on the distribution costs of coal and oil. Geothermal is also so much more efficient than these energy systems. In fact, geothermal heating and cooling can be approximately two to three times more efficient than traditional energy sources such as gas and oil.

That can reduce energy utility costs from energy by 30, 40, or even up to 65 percent. This means a geothermal system can pay for itself with five to ten years.

4. Geothermal energy is safe

Here’s another area where geothermal energy outshines other energy sources by an impressive margin. The safety of geothermal energy is in its simple nature; with no gas or oil to burn or combust, geothermal eliminates the risk of explosions.

It’s also a safer way to heat or cool your home because it produces no noxious gases or fumes that you or your family could breathe in. With geothermal, you never have to worry about a potential gas leak or carbon monoxide poisoning. It’s clean and safe.

5. Geothermal energy is eco-friendly

Lastly, home geothermal heating and cooling systems have little to no impact on the environment. This is because of the lack of combustibles, which we mentioned earlier. They produce no greenhouse gases, take up minimal land, and bear no risk of leaking oil or other dangerous products into the ground or water supply.

With Dandelion, the loop of pipes that are installed underground is what is known as a closed-loop system. This means that they don’t connect to any other groundworks or water supply piping. Dandelion's geothermal systems fill these pipes with water or a food-grade heat-conducting fluid that is completely eco-friendly.

It’s highly unlikely that any fluid will leak from the pipes; if it does, however, these extra measures ensure that your home geothermal system causes no harm to the ecosystem around your home.
