The cost of 'solar' excludes the cost of tremendous pollution at the site of production as well.  The same with wind.   You seem to think that coals 'externalities' are important but Solar and wind should have their externalities ignored.  The reality is coal burning hasn't had anything to do with acid rain for decades.   It had very little to do with it then.   And the reality is people are trying very hard to shut off oil and natural gas production too.   For base production people want to use renewables that are utterly unsuited for base production.   Nuclear power is great for base loads but environmentalists have pushed those costs to absurd levels through regulations too.
