But, alas, there are still enough places in the post -Soviet space where regular interruptions in the supply of electricity are becoming more likely the norm of life than the exception to the rules. What is there about remote places to say — it happens in rather large cities, and the reasons for this can be very different — from a mechanical cliff of wires to breakdowns at a power plant. But if in cities the solution of problems of this plan, as a rule, takes no more than half an hour, then in rural areas you can sit without light and significantly longer. And in winter, this is not particularly pleasant-it is dark, and even cold, the benefit of half the autonomous heating systems has automatic control units that depend on electricity. No light — the boiler got up, after a few hours the house will stand up.
