Global battery deliveries in 2025 was 1,600 GWh, not 3,000 GWh. Of that, only 300 GWh was used for grid storage. Even projections a decade out to 2035 only predict that yearly battery storage deployment will be 800 GWh per year, the vast majority of battery production will be used for EVs rather than grid storage.

Again, there's a reason why people talking about batteries scaling don't put their numbers in the context of electricity demand. Even with the predicted exponential growth of battery production, the scale of electricity demand is on a different level.
