Renewable Energy Sources

Renewable energy sources come from sun, wind, rain, tides, and geothermal heat - basically anything that is naturally replenished on the earth. This also includes hydrogen, Biomass, which are wood and wood waste, sewage waste, and landfill waste. There are also biofuels which are: biogas, ethanol and biodiesel. However, when these are used they emit greenhouse gases like fossil fuels. Which is why non-biomass renewable energy resources are the way to go.

Non-biomass such as hydropower, geothermal, wind, and solar power are the cleanest and best for the environment. Best of all, these are the most abundant.
