  •  a sloppy analysis that omits solar (0+ / 0-)

    The cited Nocera analysis is 5 years old. In that time the cost of solar cells has decreased by a factor of 4 and continues.

    The US spends 8% of its GDP on energy, 3/4 of that for fuel.  Money spent on fuel is lost, with a chunk going to fund terrorists.  The important question is how we choose to spend. Capital costs for wind are comparable to gas and cola plants while capital costs for solar are now slightly better than nuclear.  

    The Cecil Addams wise-cynic act is just a foolish distraction; of course fuel power plants will be built, the need is to make sure that policy makes fuel plants less attractive than alternatives. The Exxons, Kochs and Massy's of the world are doing everything possible to keep subsidies for coal and oil and gas higher than for alternatives (This is true even now.)

    After 40 years of fusion research it just isn't going to happen. Fusion is too big and too radioactive and apparently too hard.  Fukashima has made nuclear's frailties evident.  

    Energy conservation and efficiency is a huge opportunity that is mostly overlooked.

    •  But we also learn tremendously from accidents (1+ / 0-)

      like at Fukushima. Ocean side siting of plants will now be rethrought with tsunami protection in mind. Nuclear has received a set back, but it's actually growing out to capacity in places like Korea and China.

      Most wind/solar advocates who believe that nuclear is 'finished' have a narrow, every western oriented perspective; a kind of geographic blinders with "projection" of their own fears and wishes onto the future.

      If China, India, Vietnam, UAE is any indication the "future" will see all sorts of mixes of energy. Look at the UAE. They are building 'green city' based primarily on solar energy and super efficient architectural designed...and 4 to 8 nuclear plants. Get it?
