Electric Cars
While I like the idea of converting freeways to allow for coast to coast driving with electric cars, the total energy required for current cars, trucks, trains and planes in the US is greater than the total installed electric generation capacity in the US.
I think you have underestimated the total amount of power required. The existing power line infrastructure is just not capable of moving that much power.
Also, you are using old figures. The US currently uses less energy than China does, and only slightly more than India does. Add in Western Europe and Russia, and that gives you around 70% of the worlds energy usage. So, the US currently uses about 15% of the total. But, percentages aren't everything. The total energy usage of the US hasn't dropped. It's just that the rest of the world is using more.
So, in aggregate, it's a worse picture than you present.
