I live in a van full time. I have a 200w solar panel and a 1500w output solar battery that powers everything I use, mostly for cooking, sometimes heat. I also poop in the woods a lot. :) I do not use the internet much really. Driving is my biggest carbon footprint but I really do not put much more mileage than the average suburban person. Anyway, I try my best. I am permanently disabled so that makes a lot of it easier. Being poor dramatically lowers ones carbon footprint.
