More than 65% of our energy comes from fossil fuels like coal and oil and another 13% is nuclear energy, but very little, below 1% and up 'at 7%, are renewable power plants. Geothermal energy represents around 3%. This shows how low geothermal energy is compared to its use! So you need to know what it can do! Say no to plagiarism.

Get the original essay The cause of geothermal energy The cause of geothermal energy is the decay of nuclear particles which increase temperatures and cause the appearance of geysers, heated springs underground and another cause is rock heated just outside the mantle and the water touches them and heats up beyond the boiling point. The temperature required The temperature required for the conversion of water into energy is the boiling point and above, so it can be extremely dangerous to touch the heated water tank as you could get blisters if you touch them. I touched something that wasn't very close to it and I got a blister on my finger. But the temperature requirements may be different depending on the power plant, binary power plant needs temperature 212 degrees and 359 degrees, and flash steam needs temperature 360 ​​degrees and above. Underwater heated springsUnderwater heated springs are the primary sources of geothermal energy; rarely exist above ground sources and if there are, it is usually in a national park like Yellowstone Park . And they send a pipe down to the underground source because it doesn't cause any damage to the surface as far as the appearance of the land. History of geothermal energy. In ancient times, overhead springs were usually the reason they settled in that specific area, to bathe and get cool, heated water for cooking or washing clothes. Or take a nice hot bath. (if the water was hot enough) so we wouldn't have the cities we have without geothermal springs. It is renewable and clean. Geothermal energy is renewable because it can simply be sent back into the depths to heat up again and this process can last a long time. time, and the process only releases vapor which does not harm the atmosphere as much as CO2 and methane, and at some point it will condense into dew (water) overnight. Types of geothermal power plants are binary and flash steam, binary, there is a heat transfer unit and 2 types of water! Keep in mind: this is just a sample.

Binary PlantsThe binary power plant system is where the water temperature can be as low as boiling point and as high as 360 degrees for the system to operate. It works by sending groundwater to a heat transfer which is transferred to a continuous water source for the power plant and which raises the steam into a turbine which can produce power and the water that has passed through the heat transfer is returned downwards. depths to warm up and it goes on and on! Flash Steam Power Plants Binary power plants need 360 degrees to 212 degrees. Flash steam plants need a minimum temperature of 361 degrees and above for the power plant to operate. It sends heated water into steam and turns a turbine which turns a generator.!
