In 2008, Michigan Gov. Jennifer Granholm proclaimed her state was ready to be the Silicon Valley of clean energy. The two-term Democrat later issued an order making the permitting process more difficult for coal plants, a move that was followed by almost all of Michigan's proposed coal generators being canceled by companies or denied by the state. At the same time, she pressed for now-in-place wind and solar tax credits and the implementation of a planned regional accord to control greenhouse gases. Now, those energy initiatives are up in the air.
