I believe that when people talk about distribution losses and end use 
losses, they are talking about electrical heating, which is about 1/4 the 
efficiency of on-site fuel heating. Cause: the generation of 1.0 power 
factor electricity is very inefficient to start with (a lot of heating at 
the generator) and the transmission lines lose about 30% (at least they did 
25 years ago when I was an anti-nuclear activist, I don't know whether 
they've made the transmission lines more efficient somehow). Think of it 
electrically. If you have a generator at one end and a heater at the other, 
the generator has the same V*I as the heater, so you're starting with 50% 
efficiency (half the energy thrown into the ocean or lake).

There is a wonderful 1978 article published in, of all places, Readers 
Digest, written by an energy scientist, that presented a model for more 
efficient use of fuels (conservation), insulation of homes and businesses, 
and co-generation that would about double the energy efficiency of the US, 
ending need for any nuclear power plants (only a few percent of our power 
needs anyhow) and dramatically reducing CO2 emissions. One of the big 
bugaboos is electrical resistance heating, which should have been banned 
because it shoves the power factor closer to 1.

Furthermore, there is a transport fuel which is hydrogen-based, called 
hydrogen-adsorbed ammonium hydride. This was proven viable by Consumers 
Solar Electric Power back the 1980s, but the oil companies and the Reagan 
admin scuttled it, framing the principal (Gerald Schaflander) with mail 
fraud. He probably died in prison. The system could have completely replaced 
gasoline and diesel as a transport fuel. Sad, as he was our last chance to 
stop global warming.
