Finally - an article clarifying the sheer economic and technical scale of the transition ! A 100 year time frame might be real - considering that our entire energy infrastructure will have to be re-built. From generation to grid .....

As for our current feeble efforts involving wind and solar - I wish to point out that it doesnt really matter if their cost is reduced to $0.00 - they are not base load capable thus always recquire capitalization and operating cost of back-up power.

And I will suggest that clean CO2 free nuclear power will be a significant contributor - the glow-in-the-dark anti-nuke crowd to the contrary !
