This is another aspect of design that I see Solarpunk being highly focused on. Not just switching out existing energy sources for renewable ones, and not just designing more energy efficient devices, but moving toward devices which power themselves and aim to stand alone as far as they can. Not only does this reduce the demand for centralised resources but it comes with other key benefits, some of which off the top of my head are: * Reduced need for infrastructure - everything from fewer charging cables to reducing strain on power lines, and thus allowing existing infrastructure to last longer. * Independence during power cuts. * Allowing people to live off grid and more transient lives. * Reducing the need for economic exchange - meaning that once you have a device there are fewer running costs, thus making the utility of having devices like these accessible to a wider group of people. * Preservation of culture - bit more of a stretch, but I'd imagine future archaeologists finding a device which powers itself would be confronted with much less of a challenge than finding something and having to first work out how to power it up without damaging it.
