Comparing the U.S. Grid to Predictions From 15 Years Ago

On Monday, the Department of Energy's Lawrence Berkeley Lab released a report entitled "Halfway to Zero," referring to a goal of a zero-emission US electric grid. The report's headline claim is a bit bogus, in that we've not cut our emissions in half relative to any point in history. Instead, they're down to half of where they were projected to be in a report issued back in 2005.
