Two state governors, Bill Richardson of New Mexico and Arnold Schwarzenegger of California, are calling for the development of 30,000 MW of clean power by 2015 along with increased energy efficiency in homes, businesses and industry in the US West. The proposal, made at the North American Energy Summit in Albuquerque, New Mexico, last month, includes wind, solar and biomass. "Clean energy and energy efficiency could become a significant economic growth centre for many of our states and could help create a national economic growth cycle from the domestic investment of energy dollars in new technologies and energy efficiency," the two state. They propose the creation of a clean energy working group to develop policy proposals in time for a Western governors meeting in June 2006. A report released at the summit said conventional generating plants could not be developed in time to meet the growing energy needs along the United States and Mexico border. In addition, governors Judy Martz of Montana and Dave Freudenthal of Wyoming, both states with huge coal reserves, proposed a best practices manual for developing coal-bed methane, saying the technology's development poses challenges for communities where the facilities would be located.
