The communist electricity bill

Every month, the electricity bill lady comes to collect the money and to hand over the invoice. Normally it is about the same amount, but as soon as it gets warmer, or colder, or more humid, and we start using aircon or heating or keep the dehumidifiers running a lot, it goes up up up.
And no wonder, because the more you use, the more expensive every KwH gets, following some "the more you can afford to use, the more you are paying" kind of great communist logic.

(then I check websites like this one out, and dont really think everything is that great at all)
