  1. Small Wind:Home and Ranch Applications John W. Adams A&C Green Energy

  2. Why the need for alternative energy? • Based on known oil reserves and the worldwide consumption rate, most estimates suggest this reserve has only 50 more years of production left in it. • 89% of US total energy comes from fossil fuels • Fossil fuel combustion represents a global environmental problem • U.S. winds could generate more electricity in 15 years than all of Saudi Arabia's oil, without being depleted • The choice is: • Invest in discovery of new oil reserves (e.g. off-shore, shale oil) • Invest in clean coal technology (20% of the worlds supply of coal is in the US) • Invest in alternative energies

  3. Comparing Renewable Energies

  4. Wind in Texas 1888, San Angelo Aeromotor markets their windmills to pump water to irrigate crops and feed cattle. This new system opens up the South Plains of Texas and makes living in West Texas possible. Oil, cattle, cotton industries shape the new economy of Texas.

  5. Texas is still #1 In 2006, Texas overtook California and continues to lead the nation in total installed wind capacity, shaping our state’s future economy and strengthening our importance in the global marketplace.

  6. Presently With advanced engineering and aerodynamic designs, today’s wind turbines are more powerful than their predecessors.

  7. What are wind energy applications? Power usage • Irrigation pumps • Electric fences • Entire residence • Street lights • Barn dances • Appliances • Etc..

  8. What is "small wind" Industrial systems Small wind systems • 1+ megawatts • 1 mW = 1,000,000 watts • Weigh over 100 tons • Each blade is over 100’ • 200’ tower • Also $1,000,000 turbines • Not more efficient, just bigger • Up to 100kW • 1 kW = 1,000 watts • Weigh 5oo lbs to 5 tons • Blades are 6’ to 30’ each • Towers up to 100’ • Home, ranch, farm, business • Eligible for grants and rebates

  9. What TYPE of wind system? Grid-Tie Off-Grid

  10. Check list: Make sure you are allowed to install a wind turbine Make sure you have sufficient wind speed Find out what your electrical usage is Find funding/grant sources for your area

  11. Zoning Approval NIMBY HOA City County Minimum acreage Height restrictions 110% rule

  12. Finding the wind speed? Resources • Anemometer • Local airport • Local media • Internet • Treesandflags

  13. Power Output (W) and Energy (kWh)

  14. Monthly Electricy Usage Electric usage is listed in kWh. This data is on every monthly statement.

  15. Finding the right wind solution • Convert turbine’s output power (W) into kW • (W) x (.001) = kW • Convert kW into kWh • How many hours in a year? • (365.25) x (24) = 8,766 hrs/year • How many hours in a month? • 8,766 / 12 = 730.5 hrs/month • (730.5) x (kW) = kWh/month

  16. YOUR wind turbine • Wind speed? • Monthly electrical usage? • Typical sizes needed • 2kW – ½ of your energy • 5kW – almost all energy • 10kW – all, plus surplus • 20kW – small biz, ranch • 30kW – med. biz, ranch • <100kW – large ranch, village

  17. Cost Benefit Analysis

  18. Excess electricity production • Store in batteries • Off-grid or grid-interactive systems • Transfer excess to utility company • Grid-tie or grid-interactive systems • Net metering • Similar to ‘roll-over’ minutes on wireless phone plans • At the discretion of the utility company • Texas is one of the last states NOT mandating net metering • Only through Austin Energy or Green Mountain Energy • kWh buy back • Not at the same rate charged TO you

  19. Two basic types of towers Monopoles Lattice Towers • Single tapered pole • “Cleaner” look • More expensive • Urban applications • Single concrete base • Lattice design • Longer on-site construction • Less expensive • Rural applications • Either single concrete base or separate concrete pads (one per leg) • Usually taller

  20. Siting your wind turbine • Taller is better • At least 30’ above wind obstacles • Wide open spaces • Maybe a clearing by a shoreline • Hill crest

  21. Funding your small wind project • 30% Federal tax credits • American Recovery and Re-Investment Act (Stimulus Bill 2009) • <100 kW project • IRS Form 5695 for individuals • IRS Form 3468 for businesses • Non-profit businesses can apply for 25% grant money • 25% REAP grants • Rural Energy for America Program • <50,000 population (based on latest census) • SECO – State Energy Conservation Office grants • www.seco.cpa.state.tx.us • DSIRE • Database of State Incentives for Renewables & Efficiency • www.dsireusa.org

  22. Your final checklist • Find out if there are any restrictions against installing wind turbines in your area • Find out your area’s wind speed • Find out your monthly electric usage • Find a good site for your wind turbine • Find a wind turbine that will produce what you need • Find any funding, tax breaks or grants to help with your project • Find an installer and set your project in motion • Relax and let Mother Nature do the rest
