Major sources of Renewable Energy World are:
The most common renewable energy source is either directly or indirectly from the sun. The energy from solar power can be directly be used for home uses. In fact, many of homemade renewable energy systems are built based on solar power system. The solar power has been widely uses as the alternative power source to generate electricity, and for hot water heating, solar cooling and to power a variety of home appliances.
Besides the sun, the wind is another commonly use renewable energy source. The movement of wind is captured with the blades of wind turbines to be converted into electric energy, and then turn into electricity via transformers.
Biomass is a renewable energy source, derived from living organisms such as plants, wood and waste. Although the Biomass has not been commonly used like the sun and the wind, mainly due to the complexity involved. However, scientists are making a good progress toward generating electricity and producing transportation fuels.
Hydropower is a power generated by taking advantage of gravity when water falls from one level to another. Usually, the kinetic energy of water is captured with water turbines and turns into electric energy to generate electricity.
