The wind power industry is growing with the trend towards taller towers and larger turbine capacity. Over the past 20 years, the wind energy turbine tower has grown from 40 meters to 90 meters with turbine sizes reaching 2.5 MW. As we progress into the 21st century, the 4.0-MW and 8.0-MW turbine is on the horizon along with towers exceeding 100 meters in height.
