Cruising sailboats that can anchor away from land and the power grid for weeks or months at a time use both wind and solar. The economics seem to work compared to fuel and maintenance for a generator. I only have solar now, but considering a small windmill for when I retire and sail off into the sunset. Much of the literature discusses similar off-grid uses, like a remote hunting cabin where grid power unavailable.
Thanks for the reminder that alternative energy has a place for remote off-grid situations.
