| > Is it? Yes > And the source for that claim is? Prices on Amazon for even non-bulk purchases of batteries and PV. Even cheaper elsewhere. > You're trying to confuse fuel requirements with grid storage requirements. False. I'm giving an analogy. Uranium mines have a production rate. Battery factories have a production rate. Both are presently insufficient to be be 100% of global power. This doesn't matter in either case. > It's that emotionally charged magical thinking again. If we pretend that problems don't exist, they don't exist. ??? My emotion in this case is "boredom". Boring is good. Nobody wants civil infrastructure to be exciting. Exciting is bad. And AFAICT nobody is denying that e.g. PV needs sunlight. What we're doing is giving you the very solutions you're saying don't exist, even though you're almost certainly holding an example of it in your hand right now while reacting emotionally to the suggestion that there are other solutions besides nuclear. > What does electric transport have to do with an absolute requirement for renewable energy sources to be backed up with grid-scale energy sources? 55kWh per car * number of cars >> multiple day energy use per person * number of people > is extremely slow to ramp up ??? Newly installed nameplate capacity for PV last year is 286 GW. Even accounting for 10% capacity factor, that's quite nice. Then there's wind. |
