Wind in Colorado
Power from the wind
•Power in the wind • Effect of air density, • Effect of swept area, A• Effect of wind speed, V
R
Power in the Wind = ½ρAV3
Wind Speed (V) Most important part of
equation Power is a cubic
function of wind speed◦V X V X V◦ 20% increase in wind
speed means 73% more power
◦ Doubling wind speed means 8 times more power
(power =½ρAV3)
Effect of wind speed on production
Same turbine, two different wind regimes:
◦ Yampa (8.3 mph) 1,200 kWh/year
◦ Sheep Mtn: (18.4 mph) 6,500 kWh/year
