Yes, I have no doubt we can hit even a 90-95% renewable grid. It's the last 5% that is impossible to do without gas.

The cost of those last few percent is absolutely eye watering. The current plan to get it to 100% net zero is by having gas for the final 5% then using carbon capture and storage to offset the emissions.

you don't even need to use carbon capture and storage if you use green gas instead of fossil gas.

It is not even the final 5%, it is the final 1-2%, because you need a multi-week dunkelflaute across Europe for the gas turbines to be needed in the future. A lot will also just be curtailing. For instance EV charging might be restricted in the future in such a winter black out scenario.

Or indeed when petrol runs out as happens occasionally (in 2022 most recently). Of course there's also the problem of gas supplies stopping
