2HYDROELECTRIC POWER-General Info
- Hydroelectricity is the term referring to
electricity generated by hydropower the
production of electrical power through the use of
the gravitational force of falling or flowing
water. - It is the most widely used form of renewable
energy, accounting for 16 percent of global
electricity consumption. - Pros - Inexhaustible fuel source, minimal
environmental impact, viable source--relatively
useful levels of energy production, can be used
throughout the world. - Cons - Smaller models depend on availability of
fast flowing streams or rivers, run-of-the-River
plants can impact the mobility of fish and other
riverlife. - http//library.thinkquest.org/2033/types/hydro/adv

3The Hoover Dam Hydroelectric Power Plant
- The Hoover Dam is a large concrete dam located in
Nevada right along the Arizona border, on the
Colorado River. The dam was constructed between
1931 and 1936 under Franklin Roosevelts
administration during the Great Depression. - The dam was named in commemoration of former
president Herbert Hoover. - The Hoover Damn is a source of renewable energy
because the turbines in the dam use the water
that flows in to generate electricity. - Allows the Colorado River to be controlled,
provides regular water supply - Sources http//en.wikipedia.org/wiki/FileAnsel_A

5Tidal PowerBy Ben Hollingsworth
Tidal Power generates electricity by harnessing
the flow of the tidal changes. As high tide
approaches, the water flows through a hole in the
dam from the sea and turns the turbine which
powers the generator. When low tide approaches,
the water flows from an enclosed water body, or
estuary, and out to the sea, passing the turbines
again.
This is another type of turbine power. Offshore
turbines works similar to tidal barrages, but
does not impact an entire shallow water
ecosystems. However, it poses dangers for large
fishes who can get hurt from the turning
turbines.

to help produce a clean and renewable energy
source that produces 0.012 of Frances power
demands. - Tidal Energy is one of the oldest forms of energy
used by humans - Tide mills consist of a storage pond, where its
filled by the incoming tide through a sluice and
emptied through a waterwheel - Tides move the waterwheels, producing mechanical
power to mill grain - Tidal power is non-polluting, reliable and
predictable - The use of tidal energy could decrease the need
for nuclear power - It is renewable source of electricity because it
does not result in releasing harmful gas,
contributing to global warming nor acid rain.

12Tehachapi Wind Farm
With about 5,000 wind turbines, it is the second
largest collection of wind generators in the
world and more than three times the size of any
other wind farm in the U.S. The turbines are
operated by private companies, but collectively
produce 800 million kilowatt-hours of
electricity, which is enough to meet the
residential needs of 350,000 people every year. A
state initiative to upgrade the Tehachapi Wind
Farm began in 2008 and is expected to be
completed by 2012. By using wind power as an
energy source instead of coal or gasoline large
amounts of fossil fuels will be prevented from
entering the atmosphere.

15Solar Power-General Info
- It works by using mirrors and lenses to direct
sunlight into a single beam, which is used as a
heat source to power plants. This photovoltaic
power is harnessed by converting solar radiation
into a direct electric current, using solar
panels. - Solar Power is generally safe to the
environment, although it requires fossil fuels to
create solar power components, requires a large
amount of land to create a plant, and is
sometimes difficult to dispose of. - The cost of solar energy, compared to coal or
oil, is significantly higher.

20Chariton Valley Biomass Project- IA, USA
http//www.iowaswitchgrass.com/
- Based in Southern Iowa, the Project sought to
demonstrate the technical and commercial
possibilities of producing power from
locally-grown and harvested renewable fuel
resources such as switchgrass and other southern
Iowa grasses. - The abundance of grass could improve local
environmental benefits by improving air
emissions, improving soil conditions on local
farm lands, and enhancing wildlife habitats.
The switchgrass could generate up to 35MW of
electrical power and displace up to 5 percent of
the coal used at Alliant Energys Ottumwa
Generating Station annually.
Progress on the new biomass processing facility
at OGS during late August, 2005.
