thinking about solarpunk settlements
solarpunk concept art is not realistic at all. like, how the are you going to make those flowing glass structures? that's a lot of metal and glass in some crazy shapes. i get that it looks pretty, but that is really advanced construction. just to work on the metal, you need an established energy grid so you can power welding equipment! no way you're just going to walk into the woods and build these futuristic glass towers. even then, where do you get the metals and glass? that is a very complex supply chain!
i understand that certain materials will have to be purchased in order to have a functional #solarpunk settlement, at least at first. solar panels are very advanced materials and energy is a crucial resource so we can make an exception until better options become available. the same applies to batteries, computers, communication equipment, &c. that said, i highly doubt the wisdom of going with advanced materials for everything.
wood, cob, and other natrual materials seem like a better fit for this kind of thing. they aren't as "future world" as flowing glass and metal structrures, but the chances that you can afford to build a home with these simple materials is a lot higher. especially considering the bootstrap process, where your access to energy will be very limited until you can assemble enough infrastructure to start producing electricity.
food prep, storage, and production
electric ranges draw a lot of energy, but the alternative is a dependence on some kind of fossil fuel for cooking. on the balance, forming habits around the availability of daylight is probably a more sustainable solution. refigeration can be very energy intensive, especially if you want to be able to store relatively large quantities of food. one possible solution is a cellar. this would be a labor intensive project, but a cellar can stay quite cool year around. it isn't a fridge or freezer, but there are a lot of preservation techniques that are compatible with the temperature ranges you could expect from a cellar.
ideally you could farm outside, but depending on the climate hydroponics or greenhouses may be necessary to produce enough food for the community. indoor/vertical farming can draw a lot of energy, especially in winter, so this might not be a viable option if the only energy source is solar. wind would help, but without a friendly climate this looks like it could be a big obstacle for solarpunk / walkaway communities in northern lattitudes. of course, people did manage to survive in these places before modern farming and energy production existed. maybe it would be worthwhile to see how they managed to provide for themselves.
