The one thing to keep in mind when considering the cost to recharge is the electrical grid we have now could not sustain everyone owning an electric car. Atleast at today's electricity prices. If EVs do take off like I believe the price to keep them on the road will go up as more people need more electricity to charge them. Here in the U.S. we are already having difficulties keeping up with the rising pace of electricity consumption when almost nobody has an electric car. When many more own one it will make electricity prices rise to keep up with demand. Considering most of our electrical grid is powered by domestically produced sources of energy I am ok with that future rate increase, but it is something to keep in mind as more car companies offer more electric vehicles.
The majority of people will charge their cars at night, when demand on the grid is actually lowest. Here in the Pacific NW we actually have a surplus of electricity right now; the spring snowmelt has the hydroelectric dams pushing out 100% and actually spilling water over the top, and when all of the windmills in the Columbia River Gorge are spinning at the same time they actually have to take the windmills
offline because they are generating more power than the grid can handle.
You are correct that our grid will need major improvements in order to recharge an all-electric transportation system, but the cost of such improvements must be weighed against the enviornmental and financial costs of our current addiction to imported fossil fuels.
I see a future where windmills and solar panels are everywhere, and they are connected to huge fuel cells which can store their power for times when the wind isnt blowing. There are proposals here in the Pacific NW to build gigantic electric pumps on the Columbia, powered by the windmills, that would pump water from the
bottom of the dams back up to the
top again, effectively "storing" the surplus output of the windmills in the potential energy of the water that can once again flow thru the hydroelectric generators when needed.
Bottom line; fossil fuels are a dead end. Embrace that fact, learn it, live it, believe it.
