One morning after the next, semi-trailer trucks get off Interstate 70 near Colby in west-central Kansas.

They haul parts of giant wind turbines in 150-foot-long sections, the pieces to the Solomon Forks wind farm and the next monumental phase of the Kansas bet on wind energy. The farm will plant 105 turbines in the prairie, each towering 250 feet high.

The project is one of a wave of wind farms under construction in Kansas that will add 20 percent more electrical generation to the state’s output.
