New York Times: Utility executives in Kansas were shocked last fall when a state environmental official rejected two coal-fired power plants because of the millions of tons of carbon-dioxide emissions they could produce. In a state where coal generates 73 percent of the electricity, the pro-coal forces were unable to work their will. That ineffectiveness will be underscored as early as Friday if Gov. Kathleen Sebelius, as expected, vetoes an effort by the Kansas State Legislature to ensure the plants are approved. A handful of lawmakers seeking a new energy policy are blocking the attempt to override. The struggle over those plants is an example of a growing trend in climate-change politics. In the absence of clear federal mandates for emissions from smokestack industries, states that have been proving grounds for new environmental approaches to energy are becoming battlegrounds as well
