I'd love to see us build 50 or 100 new nuclear plants and go all-electric. Problem is, we don't have a good enough means of portable storage yet. Sure, maybe I can go 100 miles on a charge, but then I have to wait hours before I can go again. We need batteries with enough energy density to match a tank full of gasoline, and with the same ease of "refill". Some sort of swappable, rechargeable fuel cell, maybe.
In the meantime, we need to stop fucking around with hybrid cars in their current form. Having two separate drivetrains in a vehicle is stupid. What we need is gasoline-electric cars. Give me an electric car with a gasoline engine that's tuned to run at maximum efficiency at a fixed speed and does nothing but charge batteries, and I'll buy one.
