Some are calling recent clean-energy actions by New York, Massachusetts and Iowa “game-changers.” That might very well prove true in the medium-term. But we can say with confidence that they are immediate game-advancers. Why? Energy markets are affected by policy, but they are driven by price. The underlying business reality is that the real cost of wind power has dropped below that of new fossil-fuel generation. And it’s making wind and renewables a no-brainer choice for major corporations, utilities and power producers of almost every stripe. Today, states are at the epicenter of America’s renewable energy revolution. And, because we have 50 state energy markets, big positive advances in state policy can accelerate the pace of this historic shift.
