During the 1987 storm, our power lines came down and we had no electricity for two weeks. I had a husband and two school-age children at home at the time, and H and I both worked. But luckily I had a gas hob that could be also be lit with a match, and a large 1930's saucepan which used to belong to my M.I.L., with good, sturdy handles on it. We boiled water in it. It was enough water to tip in the bath and when some cold water was added it was plently for a shallow bath or a thorough strip wash. So while it was annoying and inconvenient, we coped well, and didn't have to ask any neighbours to help. Having said that - one or two of our all-electric neighbours asked US for help. So we boiled water for those neighbours, and occasionally made pots of tea or coffee for them. The large saucepan of water we boiled for them to wash with, they poured into their own bucket to take home! I scarcely knew these neighbours, but helping them created new friendships and much gratitude from them.
I am much older, and live alone today. I still have a gas hob, and the same saucepan! So I would boil water for a desperate neighbour to take away, I think - and not allow access to my home.
