    • Biomass Paige
    • 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 mostcrop and animal farms and in largeforested 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 sunlightthere is, theeasier plantsgrow – 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 thesteam 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 SProjected: • 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 continuewith the production of biomass powerplants, trees and forests will be cutdown in order to fulfill the demand.The American Heart Association andthe American Lung Association havecalled Biomass a danger to publichealth due to various issuesincluding respiratory illnesses andheart disease.
    • ECONOMIC ISSUES: competition with other energy resources• It accounts for almost 15% of the worlds 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 #1Which resource is not bio mass?b.Animal Manurec. Garbaged.Corne.Uranium
    • Multiple-choice question #2About how much of the world’s energy supplydoes biomass account for?a. 13%b. 15%c. 7%d. 35%
    • Multiple-choice question #3What type of energy is Biomass?a. Electromagneticb. Kineticc. Chemicald. Thermal
    • Multiple-choice question #4Why is Biomass widely utilized as an energysource?a. Because it has a low cost.b. Because people like to see deforestation.c. Because it produces no CO2d. It can be converted to electricity effortlessly.
