Positive Aspects:
- Power generation is centralized, allowing more efficient stationary heat engines to be used, and better pollution controls.
- Cogeneration is possible.
- Greater variety of fuels can be used, because it doesn't have to be portable.
- Regenerative braking is possible.
- Recharging can be done at home, and at any destination, eliminating travel to a refuelling station.

Negative Aspects:
- Current electrical devices don't yet provide acceptable range for most people.
- Electric cars are usually more expensive.
- Electrical devices may contain toxins, and don't last as long as IC engines.
- Electrical storage device performance decreases as temperature drops.

Overall

We're not there yet, but the benefits are so attractive we have lots of motivation to achieve them. New electrical storage devices are coming out that may soon solve the range problem, and after that the challenge is to reduce the cost via mass production. The rest is life-cycle management and proper maintenance.

If electric cars became popular then electric power infrastructure would have to be upgraded, and alot of new power stations built. But the mix of fuel sources would be far greater for stationary power. There is even possibiilty that nuclear fusion might be added to the mix in the future. If superconducting magnet technology is miniaturized, it might even be possible that each car could have its own Polywell fusion reactor, and run on a tank full of liquid sodium borohydride. Of course that's pure speculation, built on pure speculation. Forward-looking statements - ignore them!
