Explanation:



Coal



Thermal


energy



Thermal plant



In thermal power plants, thermal energy is used to generate electrical energy.


Coal is used as fuel. It is burned and the thermal energy released in form of steam is used to rotate the turbine.



Uranium



Nuclear


energy



Nuclear power


plant



In nuclear power plants, nuclear energy is used to generate electrical energy. Uranium is used as fuel. When neutron is bombarded on an atom of uranium, it converts itself into stable atoms through fission. The energy released is used to generate electricity.



Water


Reservoir



Potential


energy



Hydro-electric


power plant



The potential energy stored in the water reservoir is the source of energy used in hydro-electric power plant. The potential energy in water stored in dam is converted into kinetic energy of water which drives the turbine, hence generating electrical energy.



Wind



Kinetic


energy



Wind electricity


plant



The kinetic energy in wind is used for electricity generation in wind electricity plant. The kinetic energy in wind is transferred to the wind-turbine which thus generates electricity.
