8 Reasons Why You Should Use Geothermal Heating

The heat of the Earth is the source of geothermal power. The term “geothermal” is taken from the Greek word geo, meaning land and thermal energy, meaning fire. Electrical power is being used globally by citizens in the heating of buildings and greenhouses and other applications.

Geothermal power is considered a source of renewable energy because the water is restocked by rainfall and heat is continuously produced by the earth. This some of reasons why we should use geothermal heating, let’s discover other reasons in this article bellow.

History of Geothermal Energy

Most ancient people, including the Romans, Chinese and Native Americans, used hot water, cooking and boiling mineral resources. Hot spring water is usually used in spas, for heating and for agricultural and industrial purposes around the world. Some believe the hot mineral springs have the ability to heal naturally.

Geothermal power is a relatively new technology to produce electricity. The new electric generator was started in Lardarello in 1904 by a group of Italians. Their generator was powered by the Earth’s natural steam.

The Geysers steam field in Northern California was the first attempt to expand geothermal power in the U.S. in 1922. The project failed because of the abrasion and corrosion of pollutants and impurities contained in steam by the pipes and turbines of the day.

Some facts to Know About Geothermal energy

Geothermic energy is energy from the Earth’s ground, may be used for heating and cooling and as a form of clean electricity. But there are some important facts about geothermal heating we should know.

 It’s always on

Geothermal power plants reliably generate electricity 24 hours a day 7 days a week. The electricity supply for a geothermal power plant is extremely reliable and secure and thus exceptionally effective energy planning.

Geothermal energy usages

Geothermal energy may be used in different forms based on the chosen resources and technology — heating and cooling of houses through geothermal heat pumps, generating electricity through geothermal energy systems, and heating structures via direct usage.

Over 100 years of geothermally sourced energy:

In 1904, in Larderello, Italy, the first geothermal plant ever was built. A small turbine powered by five light bulbs was steamed from the geothermal source.

Now the US is the world’s top source of geothermal electricity, supplying the national grid more than 3.7GW. Indeed, in 1892, the first modern geothermal district heating plant was built in Boise, Idaho.

Pros and cons of geothermal heating

There are many Reasons why we should use geothermal heating. There is increasing awareness of the environmental impacts of fossil fuels — coal, oil and gas. There is also interest in environmentally friendly solutions to meet the energy needs of society.

Although fossil fuels are still abundant and inexpensive overall, alternative energy sources have risen in recent years in the midst of an unparalleled green energy wave.

Geothermal energy is among the most attractive green energy. There are many pros and cons of geothermal heating in this rich underground resource.

Find out our list of the top reasons why we should use geothermal heating in our homes.

Advantages of Using Geothermal

100% Renewable

Geothermal power is based on underground heat energy. In the water reservoirs of the earth’s crust this extreme heat is concentrated within enormous amounts. It is practically called limitless.

Clean-Burning and Low-Emission

Geothermal energy is considered clean because without burning any fossil fuels, it can be extracted and converted. Geothermal plant emissions are primarily benign vapors of water.

High Energy Potential

Oil and other fossil fuels are precisely that, endless fossils, which took many thousands of years ago to be formed. As a result, it is only possible to extract so much valuable oil from identified reserves. At some point, drilling for the earth’s resources – not to mention prohibitively harming the global climate – could become clearly not economically efficient.

Scalable Production

Geothermal is ideal for large and commercial operations in the context of pump heating and cooling systems, as well as for urban and domestic applications. Smaller operations are simpler and can be drilled on low levels, while massive geothermal power stations can turn enormous quantities of heat into electricity to feed the grid.

Base Load Stability

Geothermal energy provides an optimal stability night and day, irrespecting the requirements of lighting and climate, unlike renewables such as wind and solar.

Disadvantages of Geothermal Energy

Location Restricted

Geothermal energy’s greatest single disadvantage is its geographic position. Geothermal systems will be built in locations where energy is available, and other regions can’t access this resource. Naturally, this is not a problem if you live in a place that can easily access geothermal resources, such as Iceland.

Environmental Side Effects

Although geothermal energy usually does not emit greenhouse gasses, many of these gasses are deposited on the ground and emitted into the environment through drilling. Although such gasses are naturally emitted into the environment, the increase of geothermal plants is rising. These gasses, though, are much smaller than fossil fuels pollutants.

Earthquakes

The possibility of earthquakes is often correlated with geothermal capacity. It is attributed to shifts in the composition of the Earth after drilling. The problem is prevalent with improved geothermal power plants which push the water into the crust of the Earth to break up the resource’s usage. Nonetheless, considering that the majority of geothermal plants are remote from urban centers, the effects of these earthquakes are fairly low.

High Costs

Geothermal energy is a costly resource, with price tags for a 1-megawatt plant in reach of approx. $2-$7 million. However, if the initial expenses are high, the investment may be rebounded in a long-term project.

Sustainability

To order to ensure the viability of the geothermal energy stream the deep reservoirs must be pumped out more efficiently than depleted. In order to ensure its viability, geothermal energy has to be managed correctly.

So, as we read in this article geothermal energy becomes day by day more popular, it’s green energy and has a huge potential and other advantages, that’s reasons why we should use geothermal heating.

How to install geothermal heating system

For the correct implementation of the pipes, advanced technical knowledge and equipment are needed, so that a GHP system installation is not a project that goes without saying.

Contact your local authorities, the International Ground Source Heat Pump Association, or the Geothermal Heat Pump Network for a list of qualified installers in your area to find a suitable installer. Certified and professional Installers should be provided Demand and check references from equipment operators.

Vertical and horizontal geothermal ground heat exchange

Horizontal applications:

They are also the best residential option. It needs more land than vertical structures, but it is not as expensive. The amount of space needed decreases with slinky ground loops.

Vertical applications:

The deeper into the ground becomes much more seasonal than the horizontal structure should be. This becomes much more seasonal. High vertical systems usually vary from 33 to 160 meters (100–500 feet). Commercial buildings also prefer a vertical solution as they provide a greater energy efficiency and smaller spaces.
