I don't know. Yah I think ev's will add to the grid load but not significantly. A north American EV on average uses about the same amount of power as an electric water heater. I can attest to that. We have two in our household and yes our power bill has gone up a bit. Right now it its about 109 bucks per month, maybe a little more because of our heatwave we have been having and the AC use in our town house. But already some are choosing to add solar to their house to offset the electric use. Some are doing stand alone systems just for charging. Below is a picture of a stand alone EV charger. It gathers and stores enough power to power 3 EV's on an average daily commute of 40 miles each...or one for 120 miles or whatever combination you like. Our commutes are shorter than that so we would have a net benefit that we could either share with neighbours or even power a circuit or two in the house. These are stand alone, not connected to the grid in any way, arrive on a truck and are set up in 5 to 10 minutes. It's not something we would do now because power is cheap and abundant where we are. But they are a neat solution to problematic situations. 35 grand though. But they will too get cheaper eventually. I guess my point is that yes there are problems but there are solutions being developed and more to come. I don't think EV's are for everyone, but take one for a test drive and you might be surprised how nice of a driving experience it is. And EV's are very easy to live with in terms of not dealing with oil changes, belts, hoses, exhaust systems, catalytic converters, oil spots on the driveway, smelly garages, you can pre warm and pre cool by iphone, no worries of overheating with the AC on in traffic jams, never going to a gas station, fueling (or charging) takes about 10 seconds twice a weak (Saturday night and Wednesday night for us)...or at least that's how long it takes to plug it in. We bought a jug of washer fluid two years ago, we are almost thru it so I'll have to buy another jug, but that's all the maintenance on two vehicles in two years. Obviously they don't replace a truck or 10 passenger van but for some of us they actually are a really nice transportation solution. We have lost almost no range so far. We'll see how it goes I guess but so far I would never go back to anything with a tail pipe...and this has nothing to do with being a "greenie", its just a better way for us.
