Mike Nelson recently retired as Denver7 Chief Meteorologist. He was one of the few weathermen courageous enough to insist that we must face the reality of climate change. Mr. Nelson speaks about the enormous prospects for a Great American Super-Grid capable of supplying the entire nation with ample, clean electricity. A high voltage underground transmission system would create a lot of jobs, improve reliability, address our growing power demand, and yield a tremendous return on investment, while simultaneously working towards urgent climate goals.
