Document Summary
They can be replaced and exist in limitless supply. Uses the movement of a metal coil and a magnet in a turbine, which revolves with gas, steam (burner and boiler) or air and is connected to a generator that converts mechanical energy into electrical energy. Cold water is pumped under pressure into a layer of hot rock (volcanic areas), the reaction returns the water under pressure to the surface where with a heat exchanger a second supply of water is heated up. Steam is produced and makes the turbine move generating electricity. Uses a wind turbine, rotor blades are moved by the wind connected to a brake (stops or slows them down in very windy conditions) and a gearbox to maximize the rotation of the shaft. There is a generator to convert the energy to electricity. Uses a bank of photovoltaic cells in solar panels placed into solar arrays. These cells produce small electric charges when exposed to light.
