You can't just ramp up hydro though...and sure it's 75% hydro right now, but if you are adding another 20% to the grid to deal with electric car charging where is that coming from? Across the US there has been no hydro or nuclear investment for the past 30 years...wind and solar aren't currently being added quick enough to deal with the increased need (not to mention the push for converting all NG appliances and heating to electric).
