You can be sure Elon himself will have such a station in his own personal garage. If it "only" costs ten grand or so, many if not most of those who buy high-end Teslas and comparable future luxury cars will have it as well. If the price comes down to the range of today's chargers, they'll be standard equipment. > If you are economizing you never build for peak demand. Again, it depends on the application. Grid operators are notorious penny pinchers, but they build for significantly more than typical annual peak demand. Bridge builders, if they're not criminally incompetent, also build for significantly more than peak demand. Home EV charging, on the other hand, is going to be governed more by absolute cost than the desire to charge in the time it takes to get the kids changed out of school clothes and into the soccer uniform. > However, many cars on the grid charging slowly still requires some sort of > compensatory, mitigating, constructing effort. Fortunately, that's already happening by itself -- though it's yet to be seen if the trend will continue. Specifically, those with EVs are significantly more likely to also have solar generation on their rooftops in excess of the capacity needed just for the car. Many don't just offset the car's usage, but the entire household plus car. The math works out to roughly as much non-vehicular household energy consumption as vehicular, so those people have already built the capacity for their neighbors to get an EV without going solar and a net wash for the grid. Hopefully, though, of course, everybody will go solar, regardless of vehicle ownership.... b& -------------- next part -------------- A non-text attachment was scrubbed...
