Biomass
Biomass is a generic term used to describe fuel generated from plant or animal matter and is a renewable resource. Over 3.5% of our energy comes from biomass- the largest amount of any renewable source. Much of this energy source comes from recycling garbage or waste material. Some of it is used for electricity generation; some for heating; and some for biofuel production.
Biofuel is a generic term that includes ethanol, methanol, biodiesel, or other fuels derived from plant or animal matter. Biofuels can be generated from any organic source, but in the U.S. virtually all biofuels come from corn grown for ethanol, and to a lesser extent soybeans. Research and development is currently being conducted to improve the conversion of non-food crops (such as switchgrass and a variety of woody crops) to biofuels.
- Most biomass used to generate electricity comes from agriculture and forest residue-leftover organic matter from farming or paper-based products.

In order to reduce greenhouse gas emissions, as well as utilize a readily available energy source, landfills can be outfitted to capture the methane. This type of energy is known as landfill gas (LFG).

Unlike traditional diesel it is non-toxic and burns more completely, reducing air pollution.
