2050 was a rough date...2041 is close enough.
My main point is that there will not be mass tailoff in nuclear any time soon.
New licenses should be granted IMO. I believe that Bellefonte will come online. I personally know someone moving from Georgia to work there and word has it that TVA is planning to close Widow's Creek. You might know more about that than I though.
Getting back to the wind turbines, you can get the basic equipment for $1-2 per watt, which is not bad at all.
http://www.solardyne.com/windgenerators.htmlThat of course does not cover installation, land to put them on, and perhaps insurance. With subsidies it's possible to perhaps turn a profit over time, I don't know. I have not really looked into it that much. My area has low average wind speed and wind turbines are much harder to maintain IMO than solar panels.
I did seriously consider installing a solar panel on my property last year, but my plans got overtaken by other events. I may still consider it at some point.
There is one large thing that neither of you have mentioned or talked about and that is generation of power at the local level (ie at the consumer's place of residence or work) This would eliminate quite a bit of the problems associated with electric power high tension lines, the interruption of service, losses on the grid therefore eliminating any need for a "smart grid", elimination of research efforts to develop super conductor long haul power lines to power the "smart grid", and lowering of the "carbon" footprint of large scale generation plants. Major innovations would be needed to provide this "at the source" generation capability since wind power is not a viable alternative for localized generation. The most comprehensive method of generating the power that each person would need at the source is a method called "fuel cell generation". By developing an economical large scale fuel cell each residence could be supplied "at the source" with the power that the home requires and the "carbon" footprint is basically a zero sum quantity. All that is required is a method to supply the base ingredients to enable the fuel cell to generate the power. This can be accomplished using hydrogen as the basic ingredient. There are some questions as to the viability of such a proposal, but in the long run it eleminates many of the problems that each of you have cited.
