Biomass


  Paige Morris on, Domonique

PHYSICAL DESCRIPTION OF RESOURCE:
                      What is it?
•   Natural materials that contain stored
    energy from the sun are Biomass.
•   Wood, straw, manure, garbage and
    alcohol fuels are all examples of Biomass.
•   The plants absorb minerals and nutrients
    from sunlight in order to grow into the
    necessary materials for biomass.
PHYSICAL DESCRIPTION OF RESOURCE:
                Location
•Located in places with lots of trees,
animals, crops, and garbage.
•It is found in large densities at most
crop and animal farms and in large
forested areas.
PHYSICAL DESCRIPTION OF
           RESOURCE:
              Scale
• Biomass can be used on both large and small scale
  sites.
• Large scale power plants burn Biomass to create
  steam to produce energy.
• Home scale wood and pellet stoves have become
  increasingly common.
• The more
  sunlight
there is, the
easier plants
grow – more
 biomass.
TECHNOLOGY
                         How does it work?

 •The m ost popular way to m ake biom ass into
 power is to burn it to prod uce heat because it
               is chem ical energy.
   •The waste wood , tree branches and other
   scraps are gathered together in big trucks.
•The trucks bring the waste from factories and
   from farm s to a biom ass power where it is
           d um ped into huge hoppers.
• The biom ass is fed into a furnace where it is
  burned and the heat prod uced is used to boil
    water in the boiler, and the energy in the
steam is used to turn turbines and generators.
TECHNOLOGY
     Experimental or Mature?


 • Biomass technology has been
   around for a long time, so it is
               mature.
• Bio-fuel technology is still being
    developed and is extremely
            experimental.
USES
              Current:

  Stoves produce heat on at home
                   scale.
    Biomass is used to produce
       electricity at a large scale.
 Bio-fuels are produced from plants
           for transportation.
USE S
Projected:




 • Biofuel will become
   more available, and
  will replace fossil fuels.
ENVIRONMENTAL ISSUES
              with extracting processes
• At large scale sites,
    the burning of
  biomass to create
  energy makes, CO2

• It is argued that the
    CO2 released into
   the atmosphere by
     power plants is
  recycled by plants in
        the cycle of
     photosynthesis.
ENVIRONMENTAL ISSUES
   with processing, transporting and using

It is feared that in order to continue
with the production of biomass power
plants, trees and forests will be cut
down in order to fulfill the demand.

The American Heart Association and
the American Lung Association have
called Biomass a danger to public
health due to various issues
including respiratory illnesses and
heart disease.
ECONOMIC ISSUES:
 competition with other energy resources
• It accounts for almost 15%
  of the world's total energy
  supply and as much as
  35% in developing
  countries, mostly for
  cooking and heating.
• It is a widely utilized
  source of energy due to its
  low cost and indigenous
  nature
ECONOMIC ISSUES :
   How costs might change in the
              future

• Right now the cost of Biomass is extremely
  low because it easy to find.
• Biomass is produced naturally so the
  prices will not likely go up.
• Bio-fuel prices will go down as it becomes
  easier to produce.
Multiple-choice question #1
Which resource is not bio mass?
b.Animal Manure
c. Garbage
d.Corn
e.Uranium
Multiple-choice question #2
About how much of the world’s energy supply
does biomass account for?
a. 13%
b. 15%
c. 7%
d. 35%
Multiple-choice question #3
What type of energy is Biomass?
a. Electromagnetic
b. Kinetic
c. Chemical
d. Thermal
Multiple-choice question #4
Why is Biomass widely utilized as an energy
source?
a. Because it has a low cost.
b. Because people like to see deforestation.
c. Because it produces no CO2
d. It can be converted to electricity effortlessly.
