Iowa wind farms to produce 95% of power for customers

MidAmerican Energy is replacing motors and blades in hundreds of wind turbines in Iowa. They say the upgraded turbines will last 20-30 years and will generate substantially more power. When the four year process is completed, their customers will get 95% of their power from wind. You read that right, 95%.

“Over the last 10 years, technology has advanced,” said Spencer Moore, vice president of MidAmerican Energy. He said the new blades are between 20 and 40 feet longer. They also have a different shape, which is designed to be more efficient by 19 to 28 percent.
