Biomass Energy and Biofuels

Biomass Energy and Biofuels: "About Biomass Energy We have used biomass energy or bioenergy - the energy from organic matter - for thousands of years, ever since people started burning wood to cook food or to keep warm.

And today, wood is still our largest biomass energy resource. But many other sources of biomass can now be used, including plants, residues from agriculture or forestry, and the organic component of municipal and industrial wastes.

Even the fumes from landfills can be used as a biomass energy source. Solar PV Switchgrass crops can be harvested to make biofuels.

Credit: Warren Gretz The use of biomass energy has the potential to greatly reduce our greenhouse gas emissions.

Biomass generates
about the same amount

of carbon dioxide as fossil fuels,
but every time a new plant grows,
carbon dioxide is actually removed from
the atmosphere.

The net emission of carbon dioxide will be zero as long as plants continue to be replenished for biomass energy purposes. These energy crops, such as fast-growing trees and grasses, are called biomass feedstocks.

The use of biomass feedstocks can also help increase profits for the agricultural industry. There are three major biomass energy technology applications: Biofuels Converting biomass into liquid fuels for transportation. Biopower Burning biomass directly, or converting it into a gaseous fuel..."
