WHAT IS BIOMASS?
All organic matter is known as biomass, and
the energy released from biomass when it is
eaten, burnt or converted into fuels is called
Biomass provides a clean, renewable energy
source that could dramatically improve our
environment, economy and energy security.
Biomass energy generates far less air
emissions than fossil fuels.
Unlike combustion of fossil fuels, which
releases carbon dioxide captured by
photosynthesis billions of years ago, carbon
dioxide released by biomass is balanced by
carbon dioxide captured in the recent growth
of the biomass, so there is far less net impact
on greenhouse gas levels.
HOW WAS BIOMASS USED IN THE PAST?
Biomass was the first fuel mankind
learned to use for energy. Burning wood
for warmth and cooking and keeping wild
Some of the earliest power plants in
America were fueled by wood material
It was an abundant fuel in many parts of
the country where logging took place
It burned much cleaner than coal and it
was available before abundant oil and
natural gas was discovered
Many cultures used animal dung to burn,
and some are still doing this today
Unlike other renewable energy
sources, biomass can be converted
directly into liquid fuels— biofuels—
for our transportation needs (cars,
trucks, buses, airplanes, and trains).
The two most common types of
biofuels are ethanol and biodiesel.�Ethanol is an alcohol, created
fermenting biomass high in
carbohydrates. It is used as a fuel
additive to cut down carbon monoxide
and other emissions.�Biodiesel is made by combining
alcohol with vegetable oil, animal fat or
other recycled cooking grease and is
also an additive to reduce emissions.
When pure, biodiesel is a renewable
alternative fuel for diesel engines.
