Michael Shellenberger, Environmental Progress: An all-star group of energy and climate scholars published a scientific article in a prestigious journal pointing out that a Stanford professor’s proposal for powering the United States entirely on renewable energy sources rests upon a gigantic lie. Over the last several years, Al Gore, Leonardo DiCaprio and Mark Ruffalo and many politicians have pointed to Stanford scientist Mark Jacobson’s modeling as proof that we can quickly and cheaply transition to 100 percent renewables. What is the lie? That we can increase the amount of power from U.S. hydroelectric dams ten-fold. According to the U.S. Department of Energy and all major studies, the real potential increase is just one percent of that.
