Geothermal energy is currently believed to be one of the most advantageous sources of energy. Not only is it a renewable type of energy but is also present in most areas, outperforming even some conventional sources in many aspects.

Moreover, the first commercial geothermal power plant is planned to be built in Cornwall, UK if all the necessary funds are obtained. That should come as no surprise since some countries profit from the presence of geothermal energy on a large scale. In fact, more and more households all around the globe are investing in ground source heat pumps and heating systems to cut their costs.

Geothermal energy has many advantages, especially when compared to conventional sources of energy:. First and foremost, geothermal energy is extracted from the earth without burning fossil fuels, and geothermal fields produce practically no emissions.

Geothermal energy also has many advantages when compared to other renewable sources like solar, wind or biomass. It is an exceptionally constant source of energy , meaning that it is not dependent on neither wind nor sun, and available all year long. When looking at the availability factor, which shows how reliable and constant specific energy sources are, geothermal is ranking on the top see the figure below , way above the other groups, which supports the argument of its independence on inconstant external circumstances when delivering energy.

Due to the fact that geothermal systems only have few movable parts which are sheltered inside a building, the life span of geothermal heat pump systems is relatively high. Heat pump pipes even have warranties of between 25 and 50 years , while the pump can usually last for at least 20 years.

Unfortunately, no matter its reputation of being an environmentally friendly alternative energy source, geothermal energy also causes some minor concerns in regards to the environment. The extraction of geothermal energy from the grounds leads to a release of greenhouse gases like hydrogen sulfide, carbon dioxide, methane and ammonia. The U. Currently, the U. The power output of a geothermal power plant is highly predictable and stable, thus facilitating energy planning with remarkable accuracy.

Geothermal power plants are also an excellent means of meeting baseload energy demand, or the minimum level of demand on an electrical grid during a hour period. Geothermal energy can heat, cool, and generate electricity: Geothermal energy can be used in different ways depending on the resource and technology chosen—heating and cooling buildings through geothermal heat pumps, generating electricity through geothermal power plants, and heating structures through direct-use applications.

In , 27 countries, including the United States, generated a total of about 83 billion kWh of electricity from geothermal energy. Geothermal heat pumps use the constant temperatures near the surface of the earth to heat and cool buildings. Geothermal heat pumps transfer heat from the ground or water into buildings during the winter and reverse the process in the summer.

In fact, it is considered essentially limitless. The superheated aquifers tapped for geothermal production are continually replenished by geologic forces originating in the core of the planet.

These inexhaustible natural processes make geothermal energy an eminently renewable resource. Geothermal energy is considered clean because it can be extracted and converted without burning any fossil fuels.

As a result, there is only so much valuable oil we can extract from identified reserves. Geothermal resources have astonishing energy potential by comparison, estimated at 2 terawatts globally—about 15, times more than estimated worldwide oil reserves.

Some level of geothermal energy is available in most places. There is potential for geothermal development throughout the United States, and the process is highly scalable. Geothermal lends itself to large and commercial-scale plant operations as well as local and residential applications in the form of ground pump heating and cooling systems. Smaller operations are cheaper and can be dug at shallower levels, while large geothermal power plants can efficiently convert huge amounts of heat into electricity to feed the grid.

Unlike renewables such as solar and wind power , geothermal energy maintains an ideal stability night and day, regardless of lighting and wind conditions. That makes it eligible to supply base load electricity to the grid.
