For coal in the USA the stated cost for MWh in 2010 was $41. The external cost was $58.

This does not include for implicit and explicit subsidies. Including those would make the external costs higher.

The numbers change by country, time, energy source, and etc. so asking for a quotation is a bit of a fishing expedition. See Tables 1 and 2 at: https://www.climateadvisers.com/wp-content/uploads/2014/01/2...

Current carbon capture tech charges about $500/ton (but this number is bound to get lower) of CO2, given the CO2 produced per KWh of Natural gas is 0.41kg/KWh, that adds about $0.20 per KWh to your electricity bill. Where I’m from, our mostly natural gas electric company charges $0.10/kwh. So adding $0.20 does indeed do more than double it (for now).

Here's a source for a recent meta-analysis of hidden costs of fossil fuels [1].

Findings on the abstract already corroborate the parent comment.
