The green revolution in personal transportation has two components: emissions-free electrical energy generation and the cars that use that energy. The fact that the former is lagging in many countries cannot be blamed on the latter.

Both need to be incentivised. The energy production will be in the form of disincentives to fossils fuel generation in the form of taxes and cap-and-trade.
