Gas HAS to be used as a backup for renewables today (or at least in places without good pumped hydro?). Enough batteries to supply an entire grid for a day or two is just out of reach today.

At least in Australia, I'm not sure how the dynamics go with such a geographically diverse grid like Europe.

Yes, certainly, I agree. But, at the same time, we should be electrifying and rapidly deploying storage (both energy and heat) as quickly as possible. "Burn the ships" and commit.

> Solar PV supplied more than 10% of global electricity in the first half of 2026, but generation remains heavily concentrated around midday. Ember says rapidly expanding, cheaper battery storage could shift 34% of new daily solar generation to non-solar hours in 2026, bringing round-the-clock solar closer.
