There are so many ways to cook our veggies, grains and legumes without using electricity. In places were there is lots of sun, a Sun Oven is a good option. Even in the sunny Rocky Mountains, there are some days without enough sun to allow solar cooking. On these days, get out the rocket stove.
Sure, I occasionally still use rice cookers, slow cookers, and other electric devices. However, cooking with sunshine or twigs gives me satisfaction that can't be measured. It's as if I'm reaching in the pockets of the utility company and retrieving my money.
If you haven't yet purchased these home preparedness items, put them on your list.
Also consider a simple composting toilet or an elaborate one for other needs.
