Liberal Denver Post columnist Susan Greene likes alternative energy sources, but she isn't falling for Gov. Bill Ritter's rhetoric about the "new energy economy."

In her Tuesday column, Greene called Ritter out for praising Tri-State Generation, a leading producer of power in Colorado. Ritter applauded Tri-State for its "leadership" in the energy sector, despite the fact that less than 1 percent of the company's power comes from renewable sources.
