Yes, Mr. Krugman, you have made it clear that you would criticize Trump if he personally discovered a cure for cancer and gave it to the people for free.  I think that it might be you who is dealing with spite.  It is a legitimate posit that private enterprise can be counted on to produce energy solutions when that overall cost factors make it practical to do so.  Despite your disclaimer regarding increased costs being minor, we still see virtually no wind or solar installations that pencil out economically without quite massive government support.  Trump is merely taking a path that provides less government control of economic activity.  Many companies and individuals are currently cash rich.  They are looking for investments that make sense.  At the present time, renewable energy does not make economic sense in terms of most bang for the buck.  It is a reasonable position to posit that private companies will move to renewable when practical.
