Notes

According to the World Energy Outlook Special Report 2018 in [1], more than 80% of worldwide primary energy demand is supplied by fossil-fuel combustion, which causes serious environmental problems, e.g., smog pollution and over 90% of total greenhouse gas emission globally. To resolve the environmental problems,
main are looking at solution to preserve the earth for the future generation. In this case renewable energy is important for the future because it is reusable. We can use it as much as we can and still it is going to be available for the future.

Renewable Energy sources like Solar energy, and Wind energy are generated from natural resources and they are endless. There is no restriction or limitations on using them. They are replenished continuously. And they have very less impact on the environment.

Solar energy is from the sun that is converted into thermal or electrical energy is the cleanest and most abundant renewable energy source available in the world. Wind energy describes the process by which wind is used to generate electricity and it is adequette to supply large amount of power.
