Geothermal energy is clean because it can be generated without burning fossil fuels. Geothermal plants release a fraction of the carbon dioxide produced by fossil fuel plants, and they create very little nitrous oxide or sulfur gases [source: U.S. Department of Energy].
Why is geothermal energy clean?
First, it’s clean. Energy can be extracted without burning a fossil fuel such as coal, gas, or oil. Geothermal fields produce only about one-sixth of the carbon dioxide that a relatively clean natural-gas-fueled power plant produces, and very little if any, of the nitrous oxide or sulfur-bearing gases.
Is geothermal energy clean and safe?
Using geothermal energy is relatively clean. Most systems only emit water vapor, although some emit very small amounts of sulfur dioxide, nitrous oxides, and particulates. Geothermal power plants can last for decades and possibly centuries.
Why is geothermal energy environmentally friendly?
(1) Geothermal energy is called as renewable and sustainable because of the heat produced by earth for millions of years and because after taking hot water or steam to ground, its heat is utilized for different purposes and water formed during the process of taking the heat of fluid is injected to earth, and thus it …
Why geothermal and hydroelectric power plants are called clean source of energy?
Geothermal and hydroelectric are renewable sources of energies and produce “clean” fuel sources. … Geothermal energy does not require any fuel and as a result, any kind of pollution or greenhouse gases is not produced.
What country is the largest producer of geothermal energy?

How reliable is geothermal energy?
Geothermal energy is physically reliable because it is consistent, efficient, and can easily accommodate changes in electricity demand.
Is geothermal dangerous?
When done properly, yes. As with any industrial project there are risks involved, but when geothermal energy is extracted from the right location it is not dangerous. Geothermal energy, or “earth heat”, was enjoyed by our ancestors as they used hot springs for warmth and cleansing.
What is an example of geothermal energy?
A Geyser is an example of Geothermal energy. Hot springs, lava, and fumaroles are natural examples of geothermal energy. Geothermal power is currently more common in homes and businesses, using geothermal heat pumps to control the temperature in the building.
What is the source of geothermal energy?
Geothermal energy is produced by the heat of Earth’s molten interior. This energy is harnessed to generate electricity when water is injected deep underground and returns as steam (or hot water, which is later converted to steam) to drive a turbine on an electric power generator.
Does geothermal energy contribute to global warming?
Unlike fossil fuels, geothermal energy is a renewable resource that does not emit the greenhouse gases that cause climate change. In addition, once a geothermal system is built, the marginal costs are relatively low, because the “fuel” is free.
What is one drawback of drilling geothermal wells?
The largest single disadvantage of geothermal energy is that it is location specific. A source of renewable energy. Gases are released into the atmosphere during digging. The number of exploitable geothermal resources will increase with ongoing research and development in the industry.
What are the challenges of geothermal energy?
These challenges include a restricted resource, limited suitable geographical areas, transmission losses, and the possibility of depleting steam resources from underground wells.
