Energy is one of the most important component of our country's economic infrastructure. the source of energy is categorized in the conventional energy sources and the non conventional energy sources. 

Conventional sources of energy is a non renewable type of energy source that's why resources are very limited. we use this conventional energy sources most to generate electricity because in we need it in commercial and domestic purpose. Country with huge population required lots of electricity for the generation of electricity so we need lots of conventional resources.

Non conventional energy or we can called a renewable energy which can be generated from natural process and that is continuously replenished and this energy cannot be exhausted and it is continuously renewed. So for our future we have to concentrate on renewable energy sources so we can get electricity lots of electricity. Solar energy is a powerful source of energy that can be used to generate electricity.
