Renewable Energy effectively uses natural resources such as sunlight, wind, rain, organic wastes, tides and geothermal heat, which are naturally replenished. Also, carbon emissions from renewable energy are never from ancient, sequestered sources. Instead, renewable energy carbon is from sources that recently captured the process of photosynthesis.

For example, farm manure can be used as fuel in a biogas system. The manure contains energy from crops that were recently grown and fed to the cows. These crops actually captured carbon as they grew. CO2 emissions never exceed the amount captured by the original crops.

Another example is organic wastes from restaurants. Often these wastes go to landfills. In a Schmack biogas plant, these organics can be diverted from the landfill and used as fuel to produce renewable energy.

In 2006, about 18 percent of global final energy consumption came from renewables, with 13% coming from traditional biomass, like wood-burning. Hydropower was the next largest renewable source, providing 3%.

This means 82% of the worlds energy is derived from fossil fuels. When fossil fuels are used, carbon that has been sequestered for centuries is released into the atmosphere creating global climate change.
