From TreeHugger:
Architecture 2030 is at it again with their great graphs, this one showing what a minimal impact the 45 nukes proposed by McCain will make, but it is a bit deceptive...
The production and transmission efficiency of electricity is roughly 33% as shown on the graph, wasting 33.2QBtu while generating 15.1QBtu. That may or may not be true (I thought it was more like 50% efficient, and my first reaction was that they were piling the total energy produced on top of the total energy consumed making and distributing it, which would be graphically incorrect).
However the graph distorts and minimizes the impact of the contribution of the proposed nuclear plants by by piling their delivered output power from the nukes on top of the current delivered output AND the production and transmission losses instead of just comparing it to the delivered electricity.
The 1 QBtu is a 6.6% increase in delivered electricity supply; displayed this way on top of all of the production and transmission losses, it reads visually as a 2.02% increase.
I think that the McCain plan for 45 nuclear plants is unnecessary and probably impossible, that we can make it up in efficiency, and am a huge supporter of Architecture 2030. However this graph is designed to distort, to minimize the impact of the nuclear plants and make it look much like the graph showing the impact of offshore oil drilling that got so much play earlier.
