The Green

Renewable Energy = "Energy derived from resources that are regenerative or for all practical purposes cannot be depleted. For this reason, renewable energy sources are fundamentally different from fossil fuels, and do not produce as many greenhouse gases and other pollutants as fossil fuel combustion. Mankind's traditional uses of wind, water, and solar energy are widespread in developed and developing countries; but the mass production of electricity using renewable energy sources has become more commonplace recently, reflecting the major threats of climate change due to pollution, exhaustion of fossil fuels, and the environmental, social and political risks of fossil fuels and nuclear power." (Wikipedia) [en.wikipedia.org].

There are five main categories of renewable energy: Wind Power, Water Power, Solar Power, Biofuel and finally, Geothermal energy. Water Power accounts for roughly 50% of the renewable energy generated on the planet because it is one of the most efficient means of generating electricity. However, water power is also the most dangerous of all the renewable sources on the planet because it holds the greatest potential to alter the ecology of river-based life forms. The classic example of this is the fish salmon, which has existed for thousands of years by swimming upstream rivers and mating. The dams required for water power, or hydro-electric power, prevent most organisms from their evolutionary habits of survival on rivers.

The next most prevalent renewable energy is biomass heat, which accounts for 17% of the annual renewable energy generated on the planet. The other remaining forms of renewable energy, Solar, Wind and Geothermal make up a a very small portion of energy, but are rising every year.
