What Disney does on a small scale to have electrically powered cars doesn't necessarily translate into what is practical for the entire country. Many parts of the country currently struggle to meet the peak electric power demand on hot days in the summer. The grid would need to be significantly expanded to make enough electricity to recharge all of the EV's if widely adopted. Limited range and extended recharge times are still issues to be addressed. Sometimes a technology can only go so far. Obviously those making only EV's want to convince you this is the wave of future..........many of us refer to that as clever marketing.
I am old enough to remember when nuclear power was the answer to all of our energy concerns and the power generated would be so cheap they wouldn't bother sending out electric bills. Clearly that hasn't happened and we still have no answer to what to do with highly radioactive waste that will be around for 10,000+ years. New electric power plants would have to use something else to generate all of the electricity we would need.
