Renewable energy is the energy in any form produced from sources that are sustainable which does not make a net contribution of carbon dioxide to the atmosphere. This includes wind power, solar energy, waves and ocean tides, geothermal energy and biomass.
Renewable energy is often described as clean and green forms of energy because of their minimal environmental impact.
The advantages of renewable energy are:
Use it repeatedly without depleting it.
No contribution to global warming,
No polluting emissions
Low cost applications
Less impact on health

Energy saving lightbulbs use around four times less energy than a standard light bulb. In place of a 40W bulb, you would only need an 8-11W energy-saving equivalent.
