11 1. A computer turns the rotor to face the wind. 3. The blades turn a shaft inside the nacelle that spins a generator that makes electricity. 4. Power cables inside the tower take electricity from the generator to underground power lines. 2. The blades begin to rotate when the wind speed reaches 8 mph How Wind Turbines Make Electricity 5. Underground lines take the electricity to our substation. From there, the electricity goes into overhead power lines.

30 Lee-DeKalb Wind Energy Center 145 GE wind turbines – 19 in Lee County and 126 in DeKalb County 217.5 megawatts Each turbine uses about one acre of land, including access roads Approximately 75 landowners involved in project
31
31 Lee-DeKalb Wind Energy Center Towers are 262 feet tall at the hub Each wind turbine has three blades Atop each tower sits a nacelle Nacelle houses the generator Operates in wind speeds up to 55 mph Best wind speed is 25 and 35 mph
32
32 Lee-DeKalb Economic Benefits Estimated over 30 Years $400 million direct investment $42 million expected in property taxes $50 million expected in landowner payments $50 million in salaries and benefits to about 20 employees $60 million expected in purchase of local goods and services over 30 years
