Title: Alternative Sources of Power
1Alternative Sources of Power Energy
2Alternative 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.
4Energy 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.
5Bio-Mass
6Prior 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.

10- 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!

17- 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.

20Economic 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.
