Background - Against
  • Scientific
  • Noise
  • Undesirable sound
  • Waves
  • audible range is 20 Hz to 20 000 Hz
  • Pressure fluctuations of the air
  • Electrical Energy
  • Electrical energy production must meet the
    electrical energy demand AT THAT TIME

4
Arguments Against
  • Ecological
  • Placed in mountains migration patterns affected
  • 2000 bats were killed in a 2 month period in West
    Virginia
  • Mountain fog compounds issue
  • Weight of turbine requires massive blasting into
    the rock
  • Scientific and Health
  • Sound is added to existing sound causing an
    increase in amplitude
  • Sound is created from rotation and wind
    interfering with the rotating blades
  • Sound intensity falls off exponentially
    recommended below 65 dB

5
Arguments Against
  • Political and Economical
  • Only 1 of electricity in Canada in 2008 came
    from wind
  • Residential energy use in Canada in 2007 was only
    38.5 electricity (Natural Gas, wood, oil) only a
    2 increase from 1990
  • Equipment can be damaged in high winds so it is
    often shut down
  • Most jobs created are only associated with
    construction
  • Requires the construction of new transmission
    lines added costs
  • Global Wind Energy Council, a pro wind
    association, links construction with government
    subsidy
  • Government initiated carbon tax required to
    support wind turbine development
  • Government subsidies would have a greater impact
    with promotion of energy efficiency within homes

Background InformationFor
  • Wind turbines and power generation
  • Wind turbines generate power by wind turning a
    rotor
  • This mechanical energy is then converted into
    electrical energy
  • Renewable Energy
  • Energy which comes from a source that is
  • Greenhouse Gas Emissions
  • In 2007 Canadas greenhouse gas emissions were
    747 Mt- this is 33.8 above the previous Kyoto
    target
  • Energy generation from fossil fuels (coal, oil,
    gas) are major contributors to these emissions

8
Wind Power is a Good Option
  • Ecological
  • Wind power is 100 renewable energy
  • Wind is a renewable resource which will never be
    consumed
  • Wind power is emission free
  • Since no fossil fuels are being burned in the
    process, there is no greenhouse gas emissions
  • Also no harmful by-products (like there would be
    with nuclear)

9
Wind Power is a Good Option
  • Economic
  • 3. Less energy production loss during times of
    repairs
  • One wind turbine can be repaired will others are
    still generating electricity
  • 4. Option for individuals to generate power
    off-the-grid
  • Air X 400 X Wind Generator can be purchased at
    Canadian Tire 800.00
  • Generates 38kW/month, average household uses
    1000kWh per month
