> 150 GWh/annum is just 17 megawatts! ... no no no ... these aren't single use cells, instantaneous power isn't a meaningful unit (I mean energy/time is technically power, but one couldn't compare this to power as measured from a traditional power plant or anything like taht). If one had to somehow contort the output into watts: Recharged every week, 150GWh of car batteries would eat ~1GW of grid capacity. It is still a very long way from any meaningful fraction of grid energy (~4TW globally), but watts really aren't the right unit to measure production capacity.
