Energy resources or power resources are the primary input in the production of goods and services. The wheels of progress move with the flow of energy. They are one of the critical elements in raising the living standards of any country. Safe, affordable and reliable energy in sufficient quantities is a must for any developing country. 

Energy in itself be classified into several types based on the following criteria

 The two major types of energy resources are: 

 The energy resources, which cannot be easily replenished, are known as non-renewable energy resources. 

Some common examples are: Coal, Petroleum, and Natural Gas 

 

The energy resources, which can be renewed or replenished, are known as renewable energy resources. 

Some common examples are: Hydroelectricity Solar Energy Wind Energy Tidal Energy, and Geothermal Energy 

1.Solar

2.Wind power

3.Hydroelectric energy

4.Biomass

5.Hydrogen and fuel cells

6.Geothermal power

7.others like oceans,etc

·         Does not cause pollution

·         Environment friendly

·         Log lifetime

·         High initial investment

Cumulative photovoltaic capacity increased by more than 75GW, by 2016, and reached atleast 303 GW, sufficient to supply 1.8% of the world’s total electricity consumption. The top installers of 2016-2017 were China, the United States and India. The largest plant is found in China.

In 2009 July, India unveiled a US$19bn plan to install 20GW of solar power capacity by 2020. India’s installed PV generation has been expanding at a very rapid pace in recent yrs, with the total capacity increasing from 10MW in 2010 to over 16,200MW as of September 2017. Gujarat solar parks (605MW) and charanka solar park (214GW) are the large scale producers.
