Matt, this is a great point. It was a rallying cry for Trump in 2016 and was a central talking point for Romney in 2012. The decommissioning of coal plants has remained steady, even under the Trump administration, as states and utilities move toward renewables. This year we've seen coal dip below renewables and reach new lows in energy production. It will be interesting to see where coal is next year, and whether this year was an aberration, a new floor for coal, or the start of a dramatic drop in its position in energy portfolios.
