HYDROELECTRIC 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.

The 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

The Bear Swamp Hydroelectric Generating
Complex(Rowe and Florida Massachusetts at the
Deerfield River) constructed in 1968 and
finished in 1974built to meet the expanded peak
load periods when New Englands electricity
consumers place the heaviest demand on the
system. 88 acres big and stores about 1.7
billion gallons of water at 1,600 feet above sea
level. generates electricity from underground
pumped storage and affiliated two conventional
hydroelectric stations. They can produce 600
megawatts of power for up to 6 hours during the
day. considered a renewable energy source that
is a viable alternative to fossil fuels because
the major generating units are twin, reversible
pump turbines planted deep within the hillside
on the south bank that work in unison.

Tidal PowerBy Ben Hollingsworth
  • How It Works

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.

  • Pros
  • Protects stretches of coast from storm tides, and
    erosion from large waves.
  • Cons
  • Destroys shallow water marine ecosystems.
  • Changes coastline currents.
  • Prevent wastes from rivers to flow out to sea.
  • Pros
  • Very predictable and reliable
  • Produces huge amounts of energy. (The largest in
    the world produces as much energy as 12 nuclear
    plants)
  • Cons
  • Only can run for 10 hours a day.
  • Expensive to build.

Rance River Estuary Tidal Power Plant, France.
  • The Rance River Estuary set the standard for
    tidal power plants around the world. The power
    plant uses the natural tides of the Rance River
    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.

ANNAPOLIS ROYAL RIVER TIDAL POWER PLANT
  • The Annapolis Royal Generating Station is a 20 MW
    tidal power station located on the Annapolis
    River in Canada
  • Only tidal generating station in North America
  • Tidal harnesses to generate electricity has been
    under discussion for the Bay of Fundy
  • Effectively generates electricity, but the
    blocking of water flow by the dam is a negative
    consequence

Tehachapi Wind Farm
  • California, USA

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.

Solar 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.

16
Nellis Solar Power Plant, NV USA
  • Located within the Nellis Air Force Base in Clack
    County, Nevada
  • Occupies 140 acres of land
  • The system contains approximately 70,000 solar
    panels
  • The power plant generates around 25 million
    kilowatt-hours of electricity annually for
    residents of the Nellis area, as well as the
    military base
  • This should save Nevada around 1 million in
    power costs annually and reduce carbon dioxide
    emissions by 24,000 tons each year.

Photovoltaic Cells Homes
  • The use of photovoltaic cells can be used as a
    substitute for buying electricity from local
    power plants.
  • The cost of running an electrical line to a
    residential home is significantly more than using
    photovoltaic cells.
  • Photovoltaic cells help energy demanding
    appliances like TVs, dishwashers, and blow
    dryers.

Biomass Power
  • Renewable organic waste generates carbon neutral
    electricity.
  • Wood waste is used to create energy to produce
    electricity and heat.

Environmental pros Manages waste Prevents
deforestation Reduces greenhouse gases Improves
air quality
Environmental cons Still produces some
greenhouse gases due Due to the burning of
organic matter. This is easily offset by
photosynthesis

Economic pros 60 million tons of biomass could
create 2,000 megawatts of electricity Would
reduce US dependence on Foreign oil. Would
create thousands of jobs

Chariton 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.
