    Truth is that people frequently conflate and confuse these.  I can't count the # of times where I've had (semi-informed) advocates of new nuclear power make the argument that "nuclear power is the cheapest electricity going on the grid" and had them confused because they didn't realize the economic structure (100% paid off capital costs which, putting aside that minor annoyance of decommissioning, is about 85% of the per kWh costs) that makes today's nuclear power cheap to send to the grid and why that is essentially irrelevant to the question of what one build's today.

    Also, by the way, there is the issue with your prices in that this is not the dispatchable price -- perhaps add 1 cent for storage / power management?

    In any event, my more serious disagreement is that I think these are not aggressive enough numbers in terms of targeting clean electricity (look at what Germany is achieving with the Energiewende).  Not only can we do even better than this, we should ... However, if we set targets along the lines you've laid out, we can 'surprise ourselves' with the rapidity of success and barrel past those figures.

      Berkeley Nat Lab.

      Right.... not dispatchable, but Levelized Cost of Operation over 20 years is common, no?

      Barrel past, oh yes.... When Vesta or GE comes out with a 16mw turbine, even if the cost to generate doubles, output is quadrupled, so we can see the Berkeley numbers cut in half. And that would be very attractive.

      RE conflating, U R right, comparing new generation to new generation is OK. Old compared to new is not.
