Title: Alternative Sources of Power

Alternative Sources of Power Energy

Alternative Sources of Power Energy
  • Alternative Fuels
  • Bio-Mass
  • Wind Power
  • Hydro-Power

3
  • Unlike other renewable energy sources, biomass
    can be converted directly into liquid fuels,
    called "biofuels," to help meet transportation
    fuel needs. The two most common types of biofuels
    are ethanol and biodiesel.

4
Energy Policy Act (EPAct) Alternative Fuels
  • Methanol, ethanol, and other alcohols
  • Blends of 85 or more of alcohol with gasoline
  • Natural gas and liquid fuels domestically
    produced from natural gas
  • Liquefied petroleum gas (propane)
  • Coal-derived liquid fuels
  • Hydrogen
  • Electricity
  • Biodiesel (B100)
  • Fuels (other than alcohol) derived from
    biological materials
  • P-Series The regulatory amendments add three
    specific blends of methyltetrahydrofuran, ethanol
    and hydrocarbons (known as P-series fuels) to
    the definition of alternative fuel.

Bio-Mass
6
Prior to the industrial revolution, biomass
satisfied nearly all of man's energy demands. Up
until the 1860s, the United States used biomass,
in the form of wood, for nearly 91 of all energy
consumption. In 1992 biomass generated 1.8
billion in personal and corporate income and
employed 66,000 workers. Although presently the
majority of humankind's energy requirements are
fulfilled by fossil fuel combustion, 14 of the
world still utilizes biomass.  
7
  • Biomass is any organic matter, particularly
    cellulosic or lingo-cellulosic matter, which is
    available on a renewable or recurring basis,
    including trees, plants and associated residues
    plant fiber animal wastes industrial waste and
    the paper component of municipal solid waste.

  • Plants store solar energy through photosythesis
    in cellulose and lignin cells. Cellulose is
    defined as a polymer, or chain, of 6-carbon
    sugars lignin is the substance, or glue, that
    holds the cellulose chain together.
  • When burned, these sugars break down and release
    energy exothermically, giving off CO2, heat and
    steam. The byproducts of this reaction can be
    captured and manipulated to create electricity,
    commonly called biopower, or fuel known as
    biofuel. (Both short for "biomass power" and
    "biomass fuel" respectively).

11
  • Biomass is considered to be a replenishable
    resourceit can be replaced fairly quickly
    without permanently depleting the Earths natural
    resources.
  • By comparison, fossil fuels such as natural gas
    and coal require millions of years of natural
    processes to be produced. Therefore, mining coal
    and natural gas depletes the Earths resources
    for thousands of generations.
  • Alternatively, biomass can easily be grown or
    collected, utilized and replaced.

12
  • Moreover, using biomass to create energy has
    positive environmental implications.
  • Carbon dioxide is a naturally occuring gas.
    Plants collect and store carbon dioxide to aid in
    the photosynthesis process.
  • As plants or other matter decompose, or natural
    fires occur, CO2 is released.

13
  • Before the anthropomorphic discovery of fossil
    fuels, the carbon dioxide cycle was stable the
    same amount that was released was sequestered,
    but it has since been distrupted.
  • In the past 150 years, the period since the
    Industrial Revolution, carbon dioxide levels in
    the atmosphere have risen from around 150 ppm to
    330 ppm, and are expected to double before 2050!

  • Biomass is an attractive energy source for a
    number of reasons. First, it is a renewable
    energy source as long as we manage vegetation
    appropriately. Biomass is also more evenly
    distributed over the earth's surface than finite
    energy sources, and may be exploited using less
    capital-intensive technologies.
  • Biomass provides the opportunity for local,
    regional, and national energy self-sufficiency
    across the globe. It provides an alternative to
    fossil fuels, and helps to reduce climate change.
    It helps local farmers who may be struggling and
    provides rural job opportunites.

Economic Benefits
21
  • Rural economic development and stability we
    spend 50 billion each year importing oil,
    biomass could replace half of this and direct a
    minimum of 25 billion to the U.S. economy not to
    foreign oil markets
  • The United States Department of Agriculture
    estimates that 17,000 jobs are generated for
    every million gallons of ethanol

22
  • Defending our access to foreign oil supplies is
    extremely costly. Diversification of fuel sources
    would cut down on military spending and shift the
    focus to domestic welfare.
  • The Electric Power Research Institute estimates
    that producing 5 quads of energy from 50 million
    acres of land will increase annual farm income by
    12 billion in Britain. The U.S. consumes 90
    quads annually, that's 18 times Britain's
    estimates!

23
  • Preservation of agricultural land that otherwise
    would be sold for residential development or
    industrial use wide open spaces!!
  • Sustainable agricultural techniques for these
    crops can restore and ensure soil stability and
    health along with minimizing chemical residues
    and habitat destruction.
  • Methane is 20 times more potent than CO2.
    Capturing methane from producers such as cows or
    rice fields and applying it for fuel will
    significantly reduce this greenhouse gas.

24
  • Increased carbon sequestering from the crops
    grown for biomass.
  • Use of waste from agricultural and timber
    industries. An estimated 350 million tons of
    waste that goes to landfills could be used for
    energy production.
  • No net increase in atmospheric carbon dioxide.
