Coal is used as a fuel in thermal power plants. In this type of power plants, the heat or the thermal energy generated by the burning of coal is used to convert water into steam. This steam is then used to rotate the turbines and generate electrical energy. Uranium is used as a fuel in nuclear power plants. The energy generated during the process of nuclear fission of Uranium to form stable atoms is used in these plants to generate electricity. In water reservoirs, water is stored at a height and it possesses potential energy. When the water from the reservoirs is released, the potential energy stored in the water is converted to kinetic energy. This energy rotates the turbines, thus generating electricity in hydroelectric plants. The wind has kinetic energy. The kinetic energy of the wind is used to rotate wind turbines which are connected to generators in wind electricity plants. The rotation of turbines generates electricity.
