I suspect that as solar and wind go more mainstream, driving power prices negative, we'll need to do something with all that excess energy. Grid-scale battery storage is one option but another might be to do things that would be otherwise uneconomical. As far as the canvas bag's footprint, 170+ times is like 3 years of shopping (assuming 1 trip/week) - which doesn't seem unreasonable at all. Do heavy canvas bags really last less than 3 years? And how much is washing maybe once a month going to add to that? You're not running the whole machine just for one bag right? You don't even have to toss it in the dryer after because lint isn't an issue - air-drying is fine. And drying is where most of the laundry electricity is used.
