Longest Turbine Blade Made in U.S. Headed for Testing

    On May 29, 2013, Vestas rolled out the longest wind turbine blades to be made in the U.S. Measuring 57.5 meters in length, three different prototypes were manufactured in Brighton, Colorado beginning in December 2012. But these blades aren't headed to a U.S. wind farm just yet. In fact, the blades are on a journey to a testing site in Denmark.

MidAmerican Energy Announces $1.9 Billion Wind Energy Investmest in Iowa

    Plans for MidAmerican to build new wind turbines in Iowa were recently announced, and the plans are big! Up to 656 new turbines, which equate to 1,050 megawatts of wind generation, will be built by the end of year 2015 in the state. This project will come at no net cost to the company's customers, and estimates show over $360 million in property tax revenues will be made.
