I will just answer one of your points, because this is something I looked at recently:
>On charging infrastructure I laugh: try to compute how much energy demand a single classic car, sum that for the total number of car of your nation and try to compute how many GWh/day your nation need to charge an hypothetical all-EV car's nationwide fleet. Perhaps only Norway, Sweden and Swiss with their nuclear+hydroelectric power and very low population can afford that demand. Without counting the fact that we can't distribute such energy without burn our actual transmission infrastructure.
You should do at least some rough maths before making such comments, it is not hard.
In my country - Australia:
- Electricity consumption per capita is about 11,000 kWhr/year
- There are about 0.7 cars/capita
- Annual km driven per car is about 15,000.
Electric cars get roughly 5 km range per kWhr, therefore if ALL cars in Australia became electric, the electricity consumption would increase by (15000/5)*0.7 = 2100 kWhr per year. Less than 20%.
If most of charging occurred at home at night, there would be no need to upgrade the grid, or power generation capacity, as the night-time utilisation is under 50%.
Furthermore, the batteries in the cars could, with just a little thought and effort, act as a grid reserve, feeding power into the grid during peak demand, and, in some countries, absorbing non dispatch-able power generation such as wind and solar.
Try to compute differently: how much usable energy you milk from gasoline/diesel? How many fill-up you do per week on your car? Now compute it at national scale and imaging it in electrical energy instead of chemical.
That's the "most real" consumption you can compute... Another easier and raw/spannometric computation can be counting a 70/80% recharge per day per car.
Results are far bigger than yours :-)
And I forgot to mention that Australia is one of the few developed country with a very little mean density and population so you have many possible energy sources and few people who consume them...
