Wind Energy andAscetics/Property Values
  • Concerns brought up at public hearings
  • Important to understand the underlying issues
  • property values,
  • perceived public health risks,
  • visual nuisance,
  • or money
  • Land use plays a large factor
  • Agriculture traditionally low opposition
  • Forested wildlife impacts
  • Mountain top strong visual concerns
  • Recreational property values and visual
    concerns
  • Beauty is in the eye of the beholder!

7
Proper Siting Can Balance a Wind Projects Visual
Impact
  • Communities can develop policies to safely and
    appropriately site projects based on community
    values and appropriate use of wind systems

Wind Energy and Sound
  • Wind systems are typically sited in windy areas
    where the sound of the wind generally masks noise
    from the machines.

approximately 1,000 feet from the machine.
10
Wind Energy and Sound
  • Today's turbines are much quieter than older
    technology.
  • Sound proofing of nacelle
  • More efficient blades
  • Quieter gear boxes
  • Slower moving rotors

12
Wind Turbines and Safety
  • Epileptic Seizures
  • Modern wind turbine blades generally rotate
    between 10-22 rpm, which is slow.  Epileptic
    seizures for photosensitive people are triggered
    by rates of 5 to 30 flashes per second.  The
    blades of today's wind turbines do not spin
    quickly enough to cause seizures. At maximum
    rotational speed, there would be a little more
    than 1 flash per second.

For more information about photosensitivity and
epilepsy visit the Epilepsy Foundations
website http//www.epilepsyfoundation.org/about/t
ypes/triggers/photosensitivity.cfm
13
Wind Turbines and Safety
  • Ice Throw
  • Ice throw, while it can occur under certain
    conditions, is of little danger. Setbacks
    typically used to minimize noise are sufficient
    to protect against danger to the public. In
    addition, ice buildup slows a turbine's rotation
    and will be sensed by a turbine's control system,
    causing the turbine to shut down.

Wind Turbines and Safety
  • Blade Throw
  • Blade throws were common in the industry's
    early years, but are unheard-of today because of
    better turbine design and engineering. There are
    thousands of turbines installed in Europe andin
    the U.S. - wind turbine standards ensure a high
    level of operational reliability and safety in
    the U.S. and worldwide.

Wind EnergyAvian Impacts
  • Significant expansion of renewable energy
    sources such as wind power is needed to reduce
    pollution from fossil fuels and address global
    warmingto protect birds, wildlife, and habitat
    from global warming. Fossil fuel power plants
    account for more than one third of the carbon
    dioxide emitted by the United States.

Wind Turbines and Bats
  • Wildlife experts are perplexed about the cause of
    bat fatalities inflicted by wind turbines.
  • The National Wind Coordinating Collaborative is
    actively studying the issue.
  • For more information about the efforts to
    understand this problem and other wind/wildlife
    issues visit the NWCC Wildlife Workgroup website

Cost of Wind Energy
  • Wind energy typically offsets higher cost natural
    gas fired peaking plants.
  • Large penetrations of wind complement hydro
    electric dams in the NW very well.

Wind Energy and Subsidies
  • Every energy technology is subsidized. Wind
    energy is no exception. Wind receives a tax
    credit that provides an inflation-adjusted 1.5
    cents for each kilowatt-hour generated, over the
    first ten years of the project. This credit
    reduces the tax liability of a wind farm, but is
    not a subsidy of public money flowing to the wind
    farm owner.
  • Subsidies that other energy sources receive
  • tax deductions
  • loan guarantees
  • liability insurance
  • leasing of public lands at below market prices.
  • Additional indirect subsidies include federal
    money for research and development programs and
    policy provisions in federal legislation.
