Geothermal Energy Advantages And Disadvantages

Posted by in Geothermal Energy | 0 comments

Under the earth’s surface there are vast amounts of energy. The sources of this energy are mainly radioactive decay and heat from the sun. The insulating property of earth matter is keeping the energy in place allowing us to harness it. as you go deeper in the earth you will find more heat and stable relatively stable temperatures compared to the surface.

Advantages

Geothermal energy is cheap once the initial costs have been covered. It’s not unusual to see numbers of about 1:5 in terms of energy required to the pump vs. energy delivered.

Practically unlimited resources. Some say geothermal energy stored in the earth will outlive the sun itself

Geothermal energy is green. there is no pollution or emission to speak of. This is obviously a great advantage compared to fossil fuels.

The stable temperatures provide reliable energy, excellent for providing a base source of energy. if the energy demand exceeds this levels the extra could be covered e.g. by gas, oil or other forms of energy.

Waste is not an issue because there are no fuel involved. Pipes are transporting water through heat exchangers before the sent into the earth again creating a circular water system. Geothermal power plants can be hidden under the ground aesthetically more pleasing than other power plants.

Disadvantages

There are not many disadvantages to mention, but they are great obstacles.

The first one is the steep price of investment. It could take years before the price is earned back in energy consumed. Geothermal heat systems are long-term projects and should be considered carefully. You also need enough land for the pipes and digging.

If you want a more thoroughly article about this check out Geothermal Energy Pros and Cons.The potential of geothermal energy is huge. there are mostly advantages by using such a technology, but as previous mentioned, the investment cost is steep. in the future we could see similar systems being more widely used and with other renewable energy sources contribute positively in turning the climate crisis. Interesting parallells can be drawn to similar methods such as wind energy: Wind Energy Pros and Cons.

A Brief Introduction to Geothermal Energy - Pros and Cons, Yes or No? Find Out Geothermal energy cost It really is less expensive than solar energy and it's also entirely clean and sustainable. It is not important if it's cool or hot outside the geothermal heat pump system constantly works (unlike solar panel systems for example where you really need the sun's rays to shine for the panels to produce anything).

Geothermal Energy Pros and Cons - What Are They? Geothermal energy In contrast to normal energy sources like non-renewable fuels and coal, geothermal energy is part of the renewable energy sources like wind power, solar, wave, etc. consequently after a geothermal heat pump system is set up, it is going to generate energy for many years, without the need to renew the source of the energy, because it is naturally replenished.

Geothermal Energy - Clean Energy Option Cost geothermal energy The advantage that geothermal power has over solar and wind power is the fact that geothermal energy is available 24/7, unlike wind or solar which suffer from intermittency issue, and are only available once wind is blowing and sun is shining. Geothermal energy has huge potential but only 24 countries are currently using this renewable energy source, which means that geothermal share of the market could only grow in years to come.

Here Are the Facts on Geothermal Energy Geothermal is a term that comes from two Greek words, geo which means earth and thermos which means heat. Although the energy is found far beneath the earth it comes to the surface by way of geysers, hot water springs and volcanoes. Geothermal energy disadvantages
Why Geothermal Energy Is the Future of Sustainable Power Geothermal power plant Spent water and sewage can be recycled and heated inside of geothermal water pipes. Because geothermal power requires no fuel, it is completely immune to rapid changes in global fuel prices. Geothermal power plant
