It's instructive to compare this list comparing the carbon intensity of electricity generation by state: https://en.wikipedia.org/wiki/File:Carbon_Intensity_of_Eletr... to this list of the cost of electricity by state: http://www.neo.ne.gov/programs/stats/inf/204.htm Objectively, electricity costs the most in states that have the lowest carbon intensity of generation, i.e. the highest share of wind and solar. The correlation is off the charts. Any analysis that says that wind and solar are cheaper than fossil fuels that doesn't address this simple, objective fact is a snow job. (The outliers are Washington and Oregon -- because those states use hydropower instead of solar or wind.)
