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

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

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.

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.

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

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

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

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

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

Finding the wind speed? Resources • Anemometer • Local airport • Local media • Internet • Trees and flags

Monthly Electricy Usage • Electric usage is listed in k. Wh. • This data is on every monthly statement.

Finding the right wind solution Convert turbine’s output power (W) into k. W (W) x (. 001) = k. W Convert k. W into k. Wh 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 (k. W) = k. Wh/month

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 k. Wh buy back Not at the same rate charged TO you

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

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