should be required reading by all, and forced reading for all the bozos who think a $10 a month surcharge to the electricity bill to curb global warming is too much.
I have not read the source article yet but I expect to see resource wars not included. Even so, they estimate $50 a ton CO2 in the US and a global impact of $400 a ton.
a kWh of electricity produced from coal emits ~ 2.2 lbs of CO2
> 900 kWh causes $50 of domestic and $400 of global damage
That works out to 5.5 cents a kWh domestic cost and 44 cents a kWh global cost.
Lots of unknowns in computing the future cost of warming. The source article is a middle of the road sort of number:
Central specifications show high global SCC values (median, US$417 per tonne of CO2 (tCO2); 66% confidence intervals, US$177–805 per tCO2)
Not much to discuss, the discount rate used is probably too high which makes the damage estimate less than it should be.
Russia wins under climate change. Wonder if this has anything to do with why Russians are interfering in USA elections?

NG is less than half of those numbers.
First, carbon content per BTU:
Then consider efficiency, coal plants are less than 40% efficient. NG combined cycle plants can be almost 70% efficient.
