Geothermal energy is energy obtained from the heat of the Earth, more precisely, inside of Earth.
Nowadays the major part of electrical power comes from the burning of fossil fuels, which is very polluting. Because we need to obtain electricity in a cleaner way, scientists developed a way to take the heat and generate it into electricity.
Geothermal energy is used by the energy of the Earth's heat but we must first understand how our planet is made. The Earth is composed of a large plate that keeps us isolated from the interior, which contains magma and also consists of melted down rocks.
In some areas, the water that is in contact with both ways of heating rocks can turn into steam. Steam is used to produce electricity through the tubes that the steam goes through to the geothermal center. As a normal power station, the steam runs through the turbine blade as a fan. The mechanical energy is transformed into turbine power by a generator. After passing through the turbine, the steam is led to a tank where it will be cooled down. The white smoke that is found in the chimneys of these stations is steam that is about to become again in water. The water is once again channeled into the reservoir where it will be naturally heated by hot rocks. The main difference between both of these power stations is that there is no need to burn fuel in order to produce electricity.
So, geothermal energy, like others energies we saw before, is clean and should be used instead of fossil fuels.
