Study rebuts renewables-only approach to climate-friendly power

Out today: A large team of energy experts say in a newly-published study that, from an economic and practical standpoint, achieving a nearly carbon emissions-free power system will require a wide range of energy sources, not just renewables.

Why it matters: The new paper in the Proceedings of the National Academy of Sciences comes amid a debate over how to eventually bring about the "deep decarbonization" needed to prevent the most dangerous levels of global warming.

"[T]he weight of the evidence suggests that a broad portfolio of energy options will help facilitate an affordable transition to a near-zero emission energy system."
