Bob at al, Back around 2010, one of our IEEE Pittsburgh section guys gave a seminar demonstrating that nuclear power was the only real option. Premature deaths produced by coal-burning plants would be reduced as well. Conservation offers some relief. The July 2014 IEEE Spectrum has an interesting article about the miserable efficiency of the ovens, even the high-end ones, used in 'developed' countries. And they do a poor job of cooking food. Long ago I observed that the expansion of human population was due to use of fossil fuels. Will technological developments allow even maintenance of current population levels? No present-day TechNetter may live to know the answer.

(my credo) Hi, Renewable energy sources tend to be expensive and from what I read can only be counted on for 20% of total usage. That leaves a huge hunk to be provided by "Large Infrastructure" producers. (Fossil fuel or nukes.) I do love saving energy, that is a win / win if there ever was one. Batteries cost so much they are almost useless here. Electro chemical systems are not exactly "Clean". If that 20% limit for renewable is real I think that means nuke plants for the bulk (breeder ???) is all we have left? Any Thoughts?
