So your plan for energy is:
1. Develop fusion as a way to get energy with no environmental impact.

2. Advance batteries and electric motors enough that we can have cars running solely on electricity which have the same power and range characteristics of gasoline engines.

Is that basically it? Maybe you like hydrogen instead of batteries?

I don't disagree with your premise. It seems to me, though, that hybrid technology can be applied to point #2 above. If companies have economic incentives to produce and improve hybrids, that gets us a step closer to your energy utopia.
