Blowin' in the Wind
Wind turbines near the Crowsnest Pass, Southern Alberta, Canada.
Wind turbines work on the same principle that allows airplanes to fly. The wind doesn’t push the blades, but passes over them. The resulting pressure difference between the upper and lower surfaces creates lift, which causes the rotor to turn.
Alberta currently ranks third in Canada with an installed wind energy capacity of 1,483 MW. The electricity production is equivalent to the amount needed to power approximately 380,000 average-sized homes. Since 2009, the cost of wind energy has fallen 69 per cent, making it one of the lowest-cost generating technologies available today. [Canadian Wind Energy Association]
