Why Wind Power?

• Is Wind Power Competitive?
• Wholesale prices/kwh of energy facilities
• Hydropower 4 - 8 cents/kwh
• New Wind 5 8 cents/kwh
• New Coal 6 8 cents/kwh
• New Natural Gas 6 10 cents/kwh
• New Solar 13 18 cents/kwh
• New Geothermal 4.5 7.5 cents/kwh
• New Nuclear 20-30 cents/kwh
• National Renewable Energy Lab

Wind Power Advantages

• It is perpetual
• As long as the wind blows, you have energy inputs

4
Wind Power Advantages

• It is perpetual
• Wind speed increases during day as demand
  increases.

5
Wind Power Advantages

• It is perpetual
• Wind speed increases during day as demand
  increases
• Turbines inexpensive and quick to install
• 600,000 to 1,000,000 per tower
• Often less than a year from permit application to
  operating wind farm.

Wind Power Advantages

• It is perpetual
• Wind speed increases during day as demand
  increases
• Turbines inexpensive and quick to install
• Non-polluting
• At least the operations. There are no free
  lunchesit takes resources to make these things
  and recycling at the end of their life.

Wind Power Advantages

• It is perpetual
• Wind speed increases during day as demand
  increases
• Turbines inexpensive and quick to install
• Non-polluting
• Price stability
• The wind is free it costs the same this year
  as the next, and the next, and the next.

Wind Power Advantages (cont)

• Reduced dependence on fossil fuel
• Reduced environmental impacts
• More jobs per unit of energy
• Long-term income to ranchers and farmers

12
Wind Power Disadvantages

• Wind must blow at least 1/3rd of the time

13
Wind Power Disadvantages

• Wind must blow at least 1/3rd of the time
• Need 15-18 mph constant wind

14
Wind Power Disadvantages

• Wind must blow at least 1/3rd of the time
• Need 15-18 mph constant wind
• Chops birds

15
Wind Power Disadvantages

• Wind must blow at least 1/3rd of the time
• Need 15-18 mph constant wind
• Chops birds
• Ugly?? Maybe more Surreal

16
Wind Power Disadvantages

• Wind must blow 2/3rds of the time
• Need 15-18 mph constant wind
• Chops birds
• Ugly?? Maybe more Surreal
• Costs more if environmental costs are excluded,
  but differential is decreasing

?????Megawatt?????

• A Megawatt of Installed Capacity of Wind
  Generated Electricity is enough to power about
  270 homes.
• Currently in the US we are generating enough wind
  energy to power about 5.7 million homes.
• This means that 28 million tons of CO2 will not
  go into the atmosphere each year.

US Wind Energy Installed Capacity (In MW)
32
Current Wind Power

• Currently meets over 1.5 of US needs
• Installed capacity increase
• 35 in 2005
• 27 in 2006
• 45 in 2007
• 50 in 2008
• 2007 New Wind Installed Capacity 30 of all new
  energy installations.

Potential Wind E. in NW

• --STATE--
• Oregon
• Washington
• Idaho
• Montana

• --MEGAWATTS--
• 4,900
• 3,700
• 8,300
• 116,000

Oregons Power Future

• 2 of state suitable for Wind Generation (USDOE)
• Could Oregon meet its needs with renewable
  energyHydro, Wind, Waves, Solar both
  photovoltaic and concentrated solar? Perhaps if
  coupled with an increase in efficiency of
  existing buildings, etc.

35
Coal vs Wind

• Coal
• A 60 watt Incandescent light burning for
  non-stop for one year requires 427 pounds of
  coal.
• Converting that coal to energy produces
• 3 lbs of sulfur dioxide (acid rain base)
• 3 lbs of nitrogen oxide (smog and acid rain
  base)
• 1112 pounds of carbon dioxide (greenhouse gas)
• Wind
• A single 2 MW wind turbine would only have to
  spin for 50 minutes to power that light bulb for
  a year.
• Incandescent versus Compact Fluorescent Bulbs
• A single 2 MW wind turbine would have to spin
  for 12
• minutes to power an equivalent size compact
  fluorescent bulb for a year

Stateline Stats

• Located between Wallowa and Touchet
• Some towers in WA some in OR
• Located on Private Land
• 450 Towers, 242 feet tall 14 feet in dia
• Blades 80 feet long scribe a 160 foot circle
• Turbines at top generate .667 MW power
• Each tower powers about 175 homes

41
Stateline Stats

• 450 towers times 175 homes each 78,750
• This facility will result in 300,000 tons of CO2
  NOT being put in the atmosphere each year
  compared to coal generated electricity.
• Wind turbines go on line quicklyThese in less
  than one year from initial permitting.

42
Stateline Stats

• Produce electricity from 7-56 MPH winds
• Best at 13-18 MPH winds
• Shuts down above 56 MPH winds
• Each tower has sensors to set both direction and
  pitch of the blades
• Development cost 300 million
• 667,000 each tower
