Maybe Canada is not able to plan, short term to medium term, regarding grid extension? Vote right in your next election.
Over here, the plans are pretty much in place to handle EV from a grid perspective. Hint, hint, invest in copper prices are pretty low right now, and demand will definitely increase.
Then there are the green folks you don't believe. They recon EV's will actually lighten the load on the grid, based on slowing down global warming.
And then there are the hard facts which no one can argue with. It takes 6kWh to refine one gallon of gasoline. A Tesla model S does approximately 20 miles on 6kWh. On average automotive fleets 1 gal = 24 miles. So really it is almost a wash and the extra load on the grid is no issue at all.
Then are the folks who think there will never be enough charging stations. What they forget is that most of us do less than 300 miles every normal day, all the trips they make to the gas station disappears. The EV is charged at night at home while we are sleeping and when the grid normally has a whole bunch of extra kWh's available, because we are all in bed snoring.
