Transcript of Biomass

Biomass
Energy Transformations
Raw Materials
For many reasons we use a limited amount of certain resources to keep the environment safe we use a limited amount of fossil fuels.
Cost, Efficiency, Reliability

Cost:
The U.S. cost per kwh is 11 cents
The VT cost per kwh is 14 cents
Efficiency:
70-80%
Reliability:
High
Electricity Generation
Vermont
Yes, a 50 megawatt power plant in Burlington.
Other Facts
DID YOU KNOW?
Biomass energy is a form of renewable energy. Plants, for instance, can be regrown to provide
a renewable source of biomass for energy.
2.
Biomass energy has been used by humans for most of our history on the Earth, with the
burning of wood and other biological materials for heat and cooking purposes.
3.
Many different sources of biomass can be used for energy, including woody materials such as
dead trees, branches, wood chips, and tree stumps, yard clippings, hemp, sorghum, sugarcane,
bamboo, agricultural waste, human waste, switchgrass and municipal solid waste.
4.
Bioenergy currently meets about of human energy needs around the world
5.
Ethanol is produced through the fermentation of biomass that is high in carbohydrates, such
as sugarcane, wheat, or corn.
6.
The largest biomass power station in the world in Finland produces a maximum of 265 MW of
power, and produces heat for the nearby town of Jakobstad.
7.
Biomass as an energy source is expected to increase as the human population increases and
energy demand increases, and as fossil fuels are depleted. This is especially expected to occur
in developing countries.
8.
Biomass energy does not produce sulfur or mercury emissions, and produces much less
nitrogen than coal does. This means that biomass energy reduces acid rain, smog and other
pollutants in the air when compared to coal.


Environmental Impacts
Biomass does create a habitat disturbance and is renewable.
Advantages
The cost is way higher than oil or gas
This Biomass Boiler takes up more space than a regular one
Research is needed to reduce the cost of production of Biomass based fuels
