Is 100 Percent Renewable Power In America A Possibility?

A group of researchers at Stanford University and the University of California, Berkeley, led by Stanford’s Mark Jacobson and Mark Delucchi, says that the United States can get 100 percent of its energy from renewable sources, using existing technologies, by 2050. And they lay out a state-by-state plan for doing so. Jacobson and Delucchi had previously calculated that the world could theoretically go 100-percent renewable by 2030; in this more practical plan, they focus on the United States and look forward to 2050.

They conclude that, in aggregate, the the United States’ energy mix could be: 30.9 percent onshore wind, 19.1 percent offshore wind, 30.7 percent utility-scale photovoltaics, 7.2 percent rooftop photovoltaics, 7.3 percent concentrated solar power with storage, 1.25 percent geothermal power, 0.37 percent wave power, 0.14 percent tidal power, and 3.01 percent hydroelectric power.
