EVs just charge whenever. Very few people use them like ICEs with regard to fuelling. The only thing needed to make them fit easily in the existing max output envelope is L1 chargers where they spend the day and TOU aware charging (and tarriffs). Most of the energy for charging them will never even hit the grid. And what little does will be mostly during the times of minimum usage. Fast chargers will have battery buffers anyway because no sane operator will want to pay the peak capacity rates for drawing 30MW during peak demand when their competitor next door can outcompete them by 50c/kWh by using a buffer.
You have the right order of magnitude of 3TW nameplate (you're quoting nameplate for the existing capacity which is absolutely not the same thing as CF weighted power, but you know this and you're trying to intentionally conflate the two) for solar + wind and about 3TW peak including storage and energy-limited dispatch lime hydro and w2e, but you really went off the rails with the rest. You also know that a mix of wind and solar has a higher uptime than either alone.
Maybe you should consider for half a second that the real engineers who actually think about this might have come to a different conclusion to your half-assed fermi estimate for good reasons?
- robomartin 4y ago> your half-assed fermi estimate You continue to chase me around HN to insult me any time I participate in a discussion about energy. In the past I have asked @dang to let you carry on with these insults so you could show the world exactly who you are. My reasoning included such things as letting you "get it out of your system". You have done enough of that. This is now abusive. Please. Stop.
