Most promising of all is new work by a team of researchers at Stanford, led by Mark Jacobson (who coauthored the 2009 global plan). In March 2013, they published a study in Energy Policy showing that New York state could meet all of its power needs with renewables by 2030. Jacobson and his colleagues are developing similar plans for every U.S. state, and have already published numbers for the country as a whole. “It’s absolutely not true that we need natural gas, coal or oil—we think it’s a myth,” he told The New York Times.
