It's not hard to see the result of our reliance on fossil fuels. The full impact of the BP Deepwater Horizon disaster may take a generation to reveal itself, but already hundreds of species of marine life have been affected, as have the communities that rely on the Gulf. Around the country, communities face devastating levels of water and air pollution as a result of coal burning power plants, which produce millions of tons of toxic sludge and smoke each year.
With current technology, renewable energy sources like wind, solar, and geothermal can provide 96% of our electricity and 98% of our total heating demand — accounting for almost all of our primary energy demand.

One of the first things scientists learned is that there are several greenhouse gases responsible for warming, and humans emit them in a variety of ways. Most come from the combustion of fossil fuels in cars, factories and electricity production. The gas responsible for the most warming is carbon dioxide, also called CO2. Other contributors include methane released from landfills and agriculture (especially from the digestive systems of grazing animals), nitrous oxide from fertilizers, gases used for refrigeration and industrial processes, and the loss of forests that would otherwise store CO2.q
