How is electricity generated in power stations?
There are different methods of electricity production. The most common method is to transfer mechanical energy into electricity. You can do that in different ways. In coal plants, electricity is produced by transferring heat from the burning coal and vaporizing water. Then the thermal energy is converted into mechanical energy by means of turbines. This turbines are attached to electrical generators that produces electricity when the turbine rotates. In hydro-electrical power stations, the kinetical and potential energy of a body of water is used to move turbines with electrical generators. Another method is to use solar energy to generate electricity. There are 2 methods: Photovoltaic panels and thermal conduction. Photovoltaic panels produces electricity inducing an electrical current from light. In the case of thermal conduction, the sun light is gathered and intensified over a particular point (similar to using a magnifying glass to burn dry leaves). A fluid is superheated, and its
