Conservatives insist that Obama's Clean Power Plan -- indeed, any effort to reduce carbon emissions -- will cost American consumers money and jobs. It is impossible to know the future, so there's no way to say that this is definitively false, but at this point there's enough research and modeling to indicate that it's very, very unlikely.
In fact, many studies show that an aggressive shift to clean energy and efficiency would save consumers money. For a more focused bit of number crunching, however, we turn to this new brief from Synapse Energy Economics. It models a clean-energy pathway for the US and produces specific numbers showing both the carbon and financial savings.
