Biomass Energy

Use in Canada

Definition
How does it work?
History of its development
Use in other places in the world
"Biomass Energy." Conserve Energy Future. Conserve-Energy-Future, 2014. Web. 10 Nov. 2014. <http://

The energy which can be derived from the
waste of plants and animals
. Some kinds of biomass are burned to generate energy.
Biomass energy originally emerged when the first caveman lit fire to wood and organic products.
In the 1970's, using more reliable, natural, and cheaper materials than fossil fuels came to people's interests; which helped biomass energy grasp people's attention.

Advantages
Clean Energy
Abundant & Renewable
Reduce Landfills

: capture carbon dioxide for its own growth
: come from living sources
: take waste and turn into something useful
LIFE = CYCLE
Disadvantages
Expensive
Harmful to Environment
Consume More Fuel
: food & shelters (living things)
increase methane gases (ozone layer)
bad smell -> spread bacteria & infection
Biomass energy supplies about 4.7% of Canada's primary energy demand
(2nd largest source of renewable energy after hydroelectricity).
Pulp & Paper Industry
: use tree products to power machines
Burn bark, woodchips, sawdust, "pulp liquor", and etc.
Creates heat and produce steam and electricity
Burning of Biomass
26% of Canadian homes use wood to heat their house.
20 MW biomass power plant in
Donghae
4,000 MW biomass
co-combustion power
plant in
Dangjin
In the 1980's, the Office of Technology Assessment concluded that biomass energy would not be the major energy source unless people deplete fossil fuels.
Use in India
produce
heat & electricity
produces 450 - 500 million tones of biomass energy per year
Jatropha curcas, Neem, Mahua are potential plants for biodiesel production
used together with fossil fuels
Use in South Korea
Use in the Philippines
30% of energy comes from
biomass
73% used for
cooking purposes
in rural areas
27% used in
industrial & commercial applications
92% used for
boiler fuel, drying, ceramic processing and metal production

In the 2000's, many experiments have been made for producing electricity with biomass energy. Nowadays, diverse experiments are made for using this energy in a cost-effective way.
Biomass energy is involved in the effort of trying to change the major energy source from fossil fuels.
