Generating the electricity is technically fairly easy to do using nuclear - but the NIMBY crowd will probably continue to make it difficult/impossible to construct new capacity.
Transmission, on the other hand, is a big problem. Many parts of the grid - especially those parts around major metropolitan areas, were EVs would do the most good - are already operating above design capacity.

While electric heat would definitely decrease range, newer batteries have an incredible amount of storage capacity. In really cold areas, LPG (readily available, reasonably cheap, as safe to store/carry as gasoline) heating could be used.

A central plant is more efficient and cleaner than distributed generation. If for no other reason than maintenance on the pollution control systems - the plants are constantly monitored and adjustments/repairs made when needed.

But you run into the transmission problems mentioned above.

Ie, neither solution is better.

All those alternatives come at a price. Wind takes up a lot of space and produces a lot of noise. The areas where there is enough wind on a regular basis are very limited. Solar panel production is very "dirty" and disposal of panels that run their life span (or are broken) will be a problem.

As far as I can tell, the only real, long-term solution is to reduce the demand for energy in all forms. More generation is, at best, a stop-gap measure.
