Oh, I'm all for reducing consumption of useless crap. Personally I don't buy many things, most of my spending goes toward food and books.
I thought we were talking about energy "consumption", not consumption of material goods. However, I'm still not sure how much reducing that kind of consumption is going to help in the overall picture of the climate crisis. It's also not realistic to expect that everybody is just going to stop buying things in the next 10 years.
