-edit- And before you waste your time, your calculation doesn't take into account that vehicles don't run 24x7. What you actually need to do is calculate the average kj/hr consumption rate of a vehicle, find out the average number of hours vehicles are on the road, then divide that into the consumption rate to get the real use of power per hour.
Of course, this doesn't take into account the problem of peak power usage hours, which, in the case of electric cars, would probably involve charging said vehicles late at night when power usage is at it's minimum by the simple expedient of timed chargers. Which, naturally, would be almost universally used and subsidized by the power companies because said late night power is much cheaper. And so, in summary, you don't know what you're talking about.

Oh the ignorance in that post.
If electric cars were to become norm and all owners ####****only****#### charged at night there would no longer be off-peak times. Further as previously mentioned by a poster there would be a gauranteed need for further electricity generation. Currently Alberta generates ~14,000MegaWatts of electricity, consumption is around ~10,000. It does not take a scientist to realize that 4,000MW of safety is reasonable. I am not willing to do the math, however simple, but I will tell you that adding electric cars will seriously shift the demand curve to the right whilst the the supply curve will not be able to keep up, thus raising the S=D point and hence the price. Basic economics.
In the figure below D1 represents current electricity demand and D2 demand after introduction of electric cars. We know that spending large amounts of captial to create electricity plants is not spontaneous, with that we can say that the supply is inelastic and unable to respond to increased demand.
Not only that, but financially more lucrative: P2xD2 > P1XD1, so aslong as the power grid can handle the extra load we will not see additional electricity coming online.
Currently alberta produces 40% of its electricity from coal and another 45% from natural gas, are these alternatives more ecologically sustainable? In Alberta NO.
