There is one more source from which electricity could come from. In most methods that we have seen that heat is converted into electricity except in wind farms and in hydro electric stations. We could say that wind farms too generate electricity indirectly because of heat. Air moves around and creates a wind that is strong enough force to spin the blades of a fan that in turn rotates an induction generator to produce heat, is because of heat changes in various parts of the earth. When one place is hot and another is cold, the hot air moves to the cooler area, or vice versa, and this is one of the reasons for movement of air.
Well, lets skip that, as Im not very good with metorology.
Geo Thermal Power Stations
Again. Its thermal. The core of the earth is still hot, and its not yet cooled down. People around are not letting the heat escape. The earth itself is not. Thick layers of soil surrounding the earth, with underground rivers, and lakes in place the heat is contained inside the earth for ever.
At times it becomes too hot inside, just like a mad man’s head, and it explodes and a reddish material comes out of vents called Lava from Volcanoes. You cannot generate electricity from that.
But at places, the heat beneath the earth heats up the water that lies underground, and make them ooze up to the surface, and this is called a Geyser, and at places the water can be so hot that they come out as steam. People who are smart enough use this steam to spin turbines and monetize it. Though large turbines cannot be rotated, smaller ones can, and in a place where there is a concentration of Geysers, you will find a concentration of generators too.
Now thats what a geo thermal plant looks like.
I guess I’d better close this thread now, and start a new thread called How is Electricity Distributed.
