The term Electric Power Generation refers to the conversion of energy available in different form of nature to electrical energy. Just like mechanical tools, devices, furniture, and other equipment around us, the electric power is also generated from various sources that are available in nature.

Electrical energy can be obtained from solar energy, water, wind coal, and oil. All types of energy sources are divided into two categories: Renewable or Non-renewable. The term renewable refers to energy sources that are naturally replenished after regular interval of time. While the term non-renewable refers to energy sources that continuously deplete with time are not naturally replenished with time. Let’s at first take an overview of different sources of energy that are available around us.


Energy Sources



Type: Renewable

Sun is the primary source of energy. Energy from sun can either be utilized via solar panels or can be radiated by using reflectors. 


Type: Renewable

 Water is a renewable source of energy that be used in multiple ways for power generation. Most popular method is to store it in dams.


Nuclear Fuels

Type: Non-renewable

Nuclear fuel is used in nuclear power stations as where the heat generated from nuclear item is used to convert water to steam


Type: Renewable

Wind is a moving air that is caused by differences in air pressure within our atmosphere. It can be utilized by wind turbines.


Type: Non-renewable

Coal is used as fuel in coal fired power stations where the heat generated from coal converts water to steam


Oil and Gas

Type: Non-renewable

Oil & Gas are two non-renewable sources. Gas or oil can be used as fuel to obtain energy and convert to electrical power


Types of Electric Power Generation Plants


Type: Renewable

The power plant which utilizes potential energy of water for electric power generation


Nuclear Power Plant

Type: Non-renewable

The power plant in which heat from nuclear fuel is used to produce steam from water

Coal Power Plant

Type: Non-renewable

The power plant which utilizes heat energy of coal combustion for generation of electricity


Wind Farms

Type: Renewable

An array of wind turbines which utilizes the wind enery for generation of power


Solar Power Plant

Type: Renewable

An array of solar panels which utilizes energy from sun light to obtain electricity


Diesel Power Station

Type: Non-renewable

The power station in which diesel engine is used to drive prime mover
