History of Wind Energy5000 BC
Sailboats used on the Nile indicate the
power of wind
500-900 ADFirst windmills developed in
Persia
1300 ADFirst horizontal-axiswindmills in Europe
1850sDaniel Halladay andJohn Burnham build Halladay Windmill;
start US Wind Engine Company
Late 1880sThomas O. Perryconducted 5,000
wind experiments;starts Aermotor Company
1888Charles F. Brush used windmill to
generate electricityin Cleveland, OH
Early 1900sWindmills in CA
pumped saltwaterto evaporate ponds
1941In VT, Grandpa’s
Knob turbinesupplies power to town during WWII
1979First wind turbinerated over 1 MWbegan operating
1985CA wind capacity
exceeded 1,000 MW
1993US WindPower developed
first commercial variable-speed wind turbine
2004Electricity from wind generation
costs 3 to 4.5 cents per kWh
2013Wind power provided
over 17% of renewableenergy used in US

Why Wind Energy?• Clean, zero emissions
• NOx, SO2, CO, CO2• Air quality, water quality• Climate change
• Reduce fossil fuel dependence• Energy independence• Domestic energy—national
security• Renewable
• No fuel-price volatility

Modern Wind TurbinesTurbines can be categorized into two classes based on the orientation of the rotor.
Exploring Wind - 10/19/17 - ©The NEED Project
Vertical-Axis TurbinesAdvantages• Omni-directional
• accepts wind from any direction
• Components can be mounted at ground level• ease of service• lighter weight towers
• Can theoretically use less materials to capture the same amount of wind
Disadvantages• Rotors generally near ground
where wind is poorer• Centrifugal force stresses blades• Poor self-starting capabilities• Requires support at top of
turbine rotor• Requires entire rotor to be
removed to replace bearings• Overall poor performance and
reliability

Horizontal-Axis Wind TurbinesSmall (<10 kW)• Homes• Farms• Remote Applications (e.g.,
water pumping, Telecom sites, ice making)
Large (250 kW-2+ MW)• Central Station Wind Farms• Distributed Power• Schools
Intermediate(10-250 kW)• Village Power• Hybrid Systems• Distributed Power

Large Wind TurbinesCommon Utility-Scale Turbines
• 328’ base to blade• Each blade is 112’• 200 tons total• Foundation 20’ deep• Rated at 1.5-2 megawatts• Supply about 500 homes

Potential Impacts and Issues • Property Values• Noise• Visual Impact• Land Use• Wildlife Impact
Properly siting a wind turbine can mitigate many of these issues.
