I lean pretty hard on solar for the long haul, especially for keeping lights, comms, and my fridge/freezer going (at least a few hours a day to preserve food/meds). Panels paired with a decent battery bank are basically silent, which matters a lot if you don’t want to advertise you’ve got power. Gas generators are handy for short term, but fuel storage and noise are real downsides, not to mention eventually you just run out unless you’ve got a serious stockpile or biofuel setup. I’ve also made it a point to reduce what actually *needs* power—swapped out appliances for manual versions, set up solar lanterns, even got into canning to cut down freezer dependence.
One thing I keep meaning to try is a small wind turbine
