Use what we have first to stabilize our country. We have lots of low sulfur coal in the power river basin of Wyoming, and Montana, develop a system to clean up the emissions and sell it or trade it to China and Russia. They are going to burn coal and lots of it with or with out the technology to scrub the emissions. Open more mines with every mine open would come with lots of good paying jobs, plus a fleet of hall trucks, drills, draglines, backhoes all built by Caterpillar, John Deere etc, more jobs in manufacturing. Then build more electric coal fired power plants again more jobs in manufacturing good paying ones, but use only us workers. This would create lots of railroad jobs haling the coal and machinery, and building materials to put this plan in effect. After you stabilize the negative spiral of our country then give tax credits to any one who could develop the alterative power sources and then employment the power sources in a stable country, not a country in economic turmoil
