How can electricity be produced from geothermal energy?

Answer 1

Heat from under the ground is used to make steam. This steam is used to spin turbines to generate electricity.

A:In every energy-making process that involves burning a fuel (like coal or wood) the result is that the heat of that burn is used to create steam which is sent through a turbine, which spins a generator that is connected to said turbine.

What geothermal energy does is replace the coal or wood, with the hot spot/hot spring, so it is used to make steam and make power.

A:Geothermal is one of the sources of electricity and one of the safest, how does geothermal work, let me tell you how it works. First they need to find a hot spot, this is where there is hot fluid under the ground, the hot fluid is rain water collected over the years then the magma heats it up, but sometimes the hot spots are dead for years maybe even decades this is a con about geothermal. First they drill wells into the ground and get hot fluid which is about a 5-10 thousand feet under the ground. Then magma will flow up the pipe due to pressure under the ground, and then the pressure is lessened then turns some of the magma into steam then the steam goes to a different pipe. Then the remaining hot fluid goes to a wellhead separator, and then the hot fluid instantly vaporizes. Then the hot fluid that is not flashed into steam in the wellhead separator then goes to a standard-pressure crystallizer and turns into standard pressure steam. The remaining hot fluid goes to a lower pressure generator, which produces low-pressure steam. Then all the low-pressure, high-pressure and standard-pressure steam is transferred to a turbine. Then the remaining hot fluid goes to a reactor clarifier system and then returned to the geothermal reservoir through injection wells. Then all the steam in the plant goes to the turbine, which turns geothermal energy into mechanical energy. The force and energy of the steam spins the turbine blades. The turbine blades turn a shaft, which is directly connected to an electrical generator. Then an electrical charge is created when magnets rotate in the generator. Then the large copper bars transfer the electricity to a step-up transformer, which is outside the plant. Then inside the transformer the voltage is increased, before the power is sent to the power lines. Then the power lines carry the electricity to homes and businesses.

The Geothermal source is renewable, because some of the steam in the generator turns back into the geothermal liquid and is injected back into the earth. This condensed fluid along with the fluid that did not flash to steam is injected back into the underground reservoir. Then the magma reheats the fluid, which can be used again and again.
