    2. 2. Tennessee Wind Working Group <ul><li>TNWWG provides outreach and education to rural, windy Tennessee communities on the benefits of harnessing wind energy. </li></ul><ul><li>DOE Grant through State of Tennessee </li></ul><ul><li>TNWWG provides education: </li></ul><ul><li>Hosts at least 4 Free All Day Workshops for select communities in Tennessee </li></ul><ul><li>TNWWG provides communication: </li></ul><ul><li>Maintain communication between key stakeholders including USDA, TN State Energy Office, TVA, Local Community Officials, Wind Industry, Non-profits, Schools, Environmental Groups, and interested Tennessee citizens </li></ul><ul><li>TNWWG provides consultation: </li></ul><ul><li>Facilitate TN Anemometer Loan program and assist TVA Wind Resource Assessment </li></ul><ul><li>www.tennesseewind.org </li></ul>Brandon Blevins Gil Melear Hough
    3. 3. <ul><li>Wind energy displaces </li></ul><ul><ul><li>Fuel </li></ul></ul><ul><ul><li>Emissions; carbon </li></ul></ul><ul><li>Wind provides a hedge against rising fuel prices (natural gas, coal) </li></ul><ul><li>Wind is an energy source with limited capacity contribution  other generation is also required </li></ul><ul><li>Wind can be cost-competitive with other forms of generation and may reduce electricity cost </li></ul>What are the benefits of wind energy to the power system?

    10. 11. Construction Operation Gravel Access Road 14’-20’ wide Gravel Crane Pad and Turnaround ~40’ x 60’ Subsurface Concrete Foundation ~40’ - 50’ diameter Turbine Pedestal 16’ – 18’ diameter Each wind turbine requires 0.5 - 2 acres. A typical facility requires only about 1%-3% of the total land under lease. Land Use
    11. 12. Local Economic Impact <ul><li>Economic Development </li></ul><ul><ul><li>1MW wind = $1.5-2 million of taxable equipment </li></ul></ul><ul><li>Landowner Land Lease Payments </li></ul><ul><ul><li>$3,000-5,000 / MW / Turbine /Yr </li></ul></ul><ul><li>Jobs </li></ul><ul><ul><li>Wind energy projects create a few long term O&M jobs </li></ul></ul><ul><ul><li>Create many short term jobs during construction </li></ul></ul>Case Study: South Dakota 40 MW (20 turbines) of wind energy installed. $100,000/yr in land lease payments $250,000/yr tax= 1/2 county school budget

Local/Community Ownership Options <ul><li>Municipalities & Municipal Utilities Palmdale, CA; Algona, IA; Moorhead, MN </li></ul><ul><li>Rural Electric Cooperatives </li></ul><ul><li>Farmer/Local Investors LLCs, Investors Pools, Cooperatives; Kas Brothers • Minwind Energy </li></ul><ul><li>Schools Spirit Lake, Iowa • Carleton College, Northfield, MN </li></ul><ul><li>Tribal Communities </li></ul><ul><li>Example: Rosebud, SD </li></ul>Courtesy: Windustry
    13. 14. Wind for Schools <ul><li>Community Education </li></ul><ul><ul><li>The greatest impediment to wind energy development is education. </li></ul></ul><ul><li>Student Education and Training </li></ul><ul><ul><li>Supports the education and training of K-12 students in preparation for real jobs in the future. </li></ul></ul><ul><li>Utility Education </li></ul><ul><ul><li>Utility becomes educated on variability, interconnection, and operation of grid with wind turbines operating </li></ul></ul><ul><li>Reduced Energy Costs </li></ul><ul><ul><li>School sees reduced energy savings (depends on turbines size and wind resource) </li></ul></ul>
