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.
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 or oil, to generate electricity.
Bioproducts
Converting biomass into chemicals for making products that typically are made from petroleum
