When it originally started, most companies bought huge generators to deal with the issue, these of course are expensive. For households there are smaller one, but as you know, the more its in demand the up prices tend to go. Its something one has to invest on over time but preferably one that would be considered "thee" generator to last more than 5 years or so with minimal maintenance.
At the village (rural areas) I'm considering house and home that works with propane e.g. geysers for example.
