44. BUILDING A WORLD OF DIFFERENCE ® 44 December 06, 2007 Kermit was right: “It’s not easy being green” A 2006 Black & Veatch survey of utility executives showed that 72% believe that federal legislation to limit carbon emissions will be approved in the next five years. The focus on carbon has redoubled political and popular interest in renewable and nuclear power alternatives to fossil fuels in the generation of electricity But for all the rhetoric, economics and pragmatism mean that natural gas and coal resources must continue to shoulder society’s need for power For this reason, our interest in carbon legislation focuses on the tipping point where the incentives for gas or coal use become significantly skewed toward either fuel
