15. It's very easy to say "but batteries!" and those are definitely part of the solution. California has over 14GW of batteries in a grid with roughly 50GW peak demand, and the reliability of the grid has improved as its carbon emissions go down.
16. ...but batteries are still small. In 2024, about 181GWh of lithium-ion stationary storage was deployed worldwide, plus 974GWh lithium-ion batteries in vehicles. (https://www.bnef.com/insights/37025).

17. Small-scale batteries are a thing too, even though the economics don’t always make much sense. 2024 battery attachment rates – proportion of residential PV buyers who get a battery too – were ~ 80% in Germany and Italy, ~ 50% in Switzerland, UK and California.
