I guess what I mean is, renewable doesn't need tibe 100% all the time to lead to that case. The UK is about 50% renewable overall, but if it's sunny and windy (or windy and nobody is using electricity) then that ratio jumps over 90% fast.
I think I'm just geeking out on electricity though, not making a meaningful point.
I'd disagree. Even from a pretty neoliberal kind of economics, fast fasion doesn't factor environmental "externalities" (i.e. the cost doesn't include environmental destruction) so it's massively undepriced, which artificially punps up demand for fast fashion.
In other words, the issue is caused by the way the system is set up. I.e. it's a systemic issue.
