Laramie, WY – Wyoming has slipped in the national ranking for wind power production. In 1999, the state ranked fifth in the nation for generating wind power. This year it ranks tenth. Sadrul Ula, an engineering professor at the University of Wyoming and an expert on Wyoming's energy production, says he knows why. He says nearly half of the states have enacted laws in the last few years that require a small percentage of their power to come from renewable sources. Wyoming does NOT have a renewable energy requirement. Professor Ula says wind power offered to customers in Gillette comes from wind farms in Nebraska. He says that's ironic because Wyoming has better wind farm potential.
