Those are projections based in no small part on the continuing flow of subsidies....and not accounting for the disposal costs of Solar which are quite high since the panels are toxic waste.
Neither of the assumptions built into those projections about the future of “renewables” are sound.
Agreed. It amuses me to see people insist they know where the market is headed in the future but fight efforts to make the playing field more fair so as to let the markets decide (which is what the Trump administration is doing). If renewables are the wave of the future, then they should have no problem competing against coal on economic grounds (i.e. minus the overregulation of fossil fuel production [e.g. coal] and the subsidies for renewables.)
