The amazing thing is there basically were no batteries three four years ago. And they can supply about 10% of the max power demand already. So it feels like the technologies we need are now good to go on an engineering an accounting basis. And adoption can be quite rapid. We're not saying in 50 years, 25 years, 10 years. We're looking at 5 years.

LiFePO4 scales power to energy storage at a rate of about 1:3-1:4. 1GW of "power" they can supply for 4 hours if you completely discharge the battery. But that's it. Batteries could supply 100% of the grid briefly, and you still wouldn't be anywhere near having completed a switchover.

- Gibbon1 3y agoI've looked and not seen numbers on the actual battery capacity. But I think it's about 3-4 hours at name plate power levels. I think from what I know capacity is a function of discharge rate. And wear is also a function of discharge rate and max/min charge levels. Makes the operating economics non trivial.
