In order of impact (since you say you're off-grid which implies you have batteries or storage):
1) Get an EV if you don't already have one: 20 kWh is about the perfect excess capacity to convert.
2) Upgrade fossil-fueled appliances in your home to electric appliances, like to induction cooktops and heat pumps. (Do you have a gas range? They're so poor at heating efficiency and pollute your living space.)
