Mapping how the United States generates its electricity

Looking at the first flowchart, a few things stick out to me greatly:

  * Transportation is wasting almost 80% of its input energy. 
  * Transportation rejected energy makes up 36% of rejected energy.

Electricity makes up a tiny fraction of the transportation input. How much will the rejected energy output decrease as we switch to electric cars, and even moreso electric buses and cargo trucks?

  * Electricity generation makes up 43% of rejected energy.

I haven't heard anything about more efficient electricity generation. Maybe that should be a focus of the Green Energy movement?

Have you heard the term "Smart grid?" Being able to postpone some types of usage (water heating, etc) and to quickly ramp down generation based on demand will reduce the amount of rejected energy.
