Types of Renewable Energy

There are two types of energy resources found in Nature, Renewable and Non- Renewable.  As there name suggests non renewable are fossil fuels which cannot be replenished or re-used.
Whereas on the other hand renewable sources of energy are those which can be replenished such as wind and solar energy—and will never run out. 
Discussed below are the renewable sources of energy

Solar

Most renewable energy comes either directly or indirectly from the sun. Sunlight directly or indirectly can be used for the purpose of heating and lighting homes. Can also be used for generating electricity, and for hot water heating, solar cooling, and a variety of commercial and industrial uses.

Wind

It is actually the sun that derives the winds as well, the energy is produced and harnessed with the help of the wind. whose energy is captured with wind turbines. The Earth's rotation also contributes to the winds, particularly through the Coriolis effect.

Biomass

The plants needs several essential component to grow on earth. Sunlight and water remains a crucial for the same. The organic matter that makes up those plants is known as biomass. Biomass can be used to produce electricity, transportation fuels, or chemicals. The use of biomass for any of these purposes is called biomass energy.

Hydrogen

Hydrogen is a crucial component that helps in generating living condition on this planet. It is found in many organic compounds, as well as water. It's the most abundant element on the Earth. But it doesn't occur naturally as a gas. It's always combined with other elements, such as with oxygen to make water. Once separated from another element, hydrogen can be burned as a fuel or converted into electricity. Because energy is always needed to produce hydrogen, hydrogen is not in itself an energy source, but rather a way to store and transport energy, so it is often referred to as an energy carrier.

Other than these resources we also have Geothermal, Ocean, Hydropower
