Wind Energy=Fastest Growing Electric Generation Source
• Global- Climate Change, Carbon Constraints
• National- Climate Change, Energy Independence, Economic Growth
• State- Climate Change, Renewable Portfolio Standards, Economic Growth
• Local- Economic Opportunity
Fundamentals of Wind Energy Development
• Wind
• Land
• Transmission
• Permits
• Market
Local Permitting: County
• Projects < 105 MW• Studies/ Environmental
Requirements• Timeline• Challenges/ Benefits
State Permitting: EFSC
• Wind Projects > 105 MW required, possible election on smaller projects
• Studies/Environmental Requirements
• Timeline• Challenges/Benefits
Federal Permitting: NEPA
• Federal process guided by the National Environmental Policy Act, Federal Lands
• EIS or EA• Challenges/ Benefits
Typical 100 MW Wind Farm• A $250 million dollar average capital cost
• 40-2.5 MW Turbines 67- 1.5MW Turbines
• Generates enough electricity for 30,000 average U.S. homes
• Permanent disturbed footprint is often less than 100 acres
• 200 construction jobs and 10-15 permanent jobs
Long Term Economic Benefits
• Local County Tax Revenue • 10 direct high paying benefited jobs,
ongoing operations and maintenance activities
• Lease and royalty payments paid to project landowners throughout life of project
• Indirect jobs created to support new industry
• Total local private sector economic activity generated during the life of the project will total $50-100 million.
Short Term Economic Benefits
• 8-12 month construction period provides high intensity burst of economic activity
• Project construction: average of over 200 workers and a $10,000,000 payroll
• Total economic benefit of construction activity includes $20 million in revenue to local industries; $15 million in labor income and 350 direct and indirect jobs
• $10 million in construction goods and services purchased locally, resulting in close to $15 million worth of indirect economic activity
• Substantial benefit to local housing, lodging, restaurant and entertainment industries from out of area labor
Environmental Issues• Wildlife : Birds, Bats, Owls• Visual Impacts • Noise
• 4th generation wind farm technology has overcome many of the early drawbacks: greatly reduced noise, dangers to bird life, visual impact remain most difficult to mitigate impact of wind farms

Environmental Benefits
• Carbon Dioxide Reduction: a typical 100 MW wind farm reduces carbon production by 200,000-300,000 tons annually
• Sulfur Dioxide, Nitrous Oxide, Mercury, and Particulate free energy source
• Wind power uses no water, especially important for power generation in arid Oregon agricultural areas
Why is Wind growing in Oregon?
• Wind• Transmission• Land• Economic Benefits• Regulatory Environment• Access to Markets
• Key factors that set Oregon apart in successful wind projects is a government and business climate conducive to project development, and large existing transmission infrastructure
