Types of Energy

Energy is the key input to drive and improve the life cycle. It's a gift of the nature to the mankind in various forms. The consumption of energy directly proportional to the progress and modernization of mankind. The continuous increase of population, improvement in standard for living, industrialization and the increase in demand of energy is expected to be more in near future. It is believed that at this rate of using fossil fuels, coal, natural gas, etc. there will be no energy at all.

There are two types of Energy:-

• Conventional Energy 

• Non Conventional Energy

Conventional Energy Sources

Conventional energy sources

• Oil - 40 %        

• Natural Gas - 22.5 %

• Coal - 23.3 %                 

• Hydroelectric - 7.0 %

• Nuclear - 6.5 %

• Biomass & others - 0.7 %

Non Conventional Energy Sources

Non Conventional Energy Sources

Fossil fuels supply most of the energy consumed today. They are relatively concentrated and pure energy sources, technically easy to exploit, and provide cheap energy. Presently

Conventional Energy from coal, natural gas and petroleum, hydel power are used abundantly at present. Except hydel power, the sources of thermal power i.e. other conventional energies are non renewable in nature. But the sources of non-conventional energy are flow-resources. There is no anxiety for their exhaustion. However the reserves of fossil fuels are limited.

To meet the future energy demands and to give quality and pollution free supply to growing and today's environment conscious population, the present world attention is to go in for natural, clean and renewable energy sources. These energy sources capture their energy from on going natural processes, such as geothermal, solar, wind, flowing water and biological process. 

Most form of energy, other than geothermal and tidal power ultimately come from the Sun. Some forms of energy such as rainfall and wind power are considered short term energy storage. Renewable energy is energy from a source that is replaced rapidly by a natural process and is not subjected to depletion in a human timescale.

Note:- The figures provided above about of Oil, Coal, etc may vary to date. As dependent on various websites, articles, books, the existence or capacity/storage of aforementioned sources of energy maybe different.
