10 years ago The new calculation that @ChaelKruip made solves most of this issue, but introduces a couple of new ones.
The first one is that all cooling converters now do not add to renewability (which is based on the definition of renewability), but we do correct for using partly renewable electricity. Solution is to take the cooling converters out of the consumption_nodes group.
More importantly, there is an issue with the correction to prevent double counting renewable electricity altogether. We use the sustainability_share for this, and it aggregates the renewability over all input carriers. This means that we subtract all renewable electricity from the electricity input, but we also subtract some that was not renewable. This is anyway wrong, as we should just subtract all electricity, but also count all the renewable input. Right now it doesn't work well at all with the renewability share. I think the proper solution is to look at the input of renewable energy like ambient_heat, instead of looking at heat output. In that case you also don't have to correct for using partly renewable electricity.
Another thing to be aware of that will cause trouble if subtracting all electricity are electric heaters. They get a huge penalty for being not too efficient and using only electricity to produce heat.
Finally, we have to discuss subtracting exported electricity. I think this depends on the definition for renewables.

Seems to be a problem with district heat / heat network.
This comes up quite dramatically in the 99% renewable scenario.
