It is the first process in the delivery of electricity to the consumers. Others processes include transmission, distribution, energy storage and recovery using pumped storage methods. Several fundamental methods exist to convert other forms of energy into electrical energy. The turboelectric, piezoelectric effect, and even direct capture of the energy of nuclear decay Betavoltaics are used in niche applications, as is direct conversion of heat to electric power in the thermoelectric effect. Electrochemistry is the direct transformation of chemical energy into electricity, as in a battery. The photovoltaic effect is the transformation of light into electrical energy, as in solar cells. Photovoltaic panels convert sunlight directly to electricity. There are mainly three conventional source of electric power generation, and they are thermal, hydel, and nuclear energy.

Thermal Power Generation- In thermal power plant coal or diesel is burnt to produce sufficient heat. This heat energy is utilized to produce high temperature and high pressure steam in the boiler. Hydel Power Generation- The water head is used to rotate the rotor shaft of an alternator. Water head can be naturally available or it can be created.

Nuclear Power Generation- In a nuclear power station, Uranium235 is subjected to nuclear fission. In fission process, U235 is bombarded by a beam of neutrons. The collision of neutrons with the nucleus of U235 creates huge heat energy along with other neutrons. These newly created neutrons are called fission neutrons which again hit by other U235nuclear and create mare heat energy and other fission neutrons.
