Transcript of Biomass

Biomass: Plant material, animal waste, and urban waste
Renewable Energy Source:
Biomass/Bio diesel

The biomass energy process...
has been used since our ancestors learned how to use/make fire.
supplies more renewable electricity “bio power” than wind and solar power combined.
starts with plants getting energy from the sun (photosynthesis).
functions as a natural battery for storing the Sun's energy (will last indefinitely, and provide sources of low-carbon energy)
Did you know...?
So, how do you get energy from dead stuff?
be harvested at unsustainable rates
damage ecosystems
produce harmful air pollution
consume large amounts of water
produce net greenhouse emissions
If not managed carefully, biomass for energy can...
a sustainable energy source derived from biomass or bio-waste.
converted from either thermal conversion, chemical conversion, and bio-chemical conversion. (Biomass conversions results in either solid, liquid, or gas forms.)

**This new biomass can be used for bio-fuels.**
Biomass comes in many different types:
Grasses (switch grass)
Crop residue (wheat straw or corn)
Harvested wood and forest residues
Municipal and industrial wastes (clean waste only)
Some garbage
Alcohol Fuels
All of which, can re-grow over a short period of time.
How it works:
Burning biomass is actually
of the carbon cycle.
Waste is transported
Plants take in the CO2, some plants die and turn into waste.
The use of electricity produces CO2
Waste is turned into electricity.

Chlorophyll in plants captures the sun’s energy by converting CO2 from the air and water from the ground into carbohydrates*.

(*Carbohydrates: complex compounds composed of carbon, hydrogen, and
When carbohydrates are burned, they turn back into CO2 and water, releasing the energy they captured from the sun.
Benefits of Biomass
There is no need to import fossil fuels.
Reduces expenses for electricity
Farmers/forest owners gain markets for crop residue.
Reduce global warming emissions
Produced by stuff that no one needs
Can be used as a base power
What's Base Power?
Base power is the standard amount of power that you need to live.
It is a power that can be used without any outside sources to supply it.
Biomass is cost efficient, and is a "carbon lean" fuel. It produces a fraction of the carbon emissions that derive from fossil fuels.
How will humans
Climate Changes:
Prevents forest fires
Improves air quality (less greenhouse gases)
Reliability (always there)

*cleans wood residues in forests; nothing to catch on fire
Biomass will cause less pollution because there is a reduced amount of carbon dioxide (greenhouse emissions) in the air. This means that we will have much
cleaner atmosphere
, and
less global warming.
