That means for the next decade or so, the fact that the U.S. gets 80 percent of its energy from fossil fuels is unlikely to change much, though the relative balance of coal, oil and natural gas will change. And if natural gas, the least polluting of the fossil fuels, is to play a bigger role, then fracking wells, gas pipelines and wastewater management will all have to be done correctly. “It’s not magic,” Moniz said.
