  1. Interesting concept. Made me rethink a thing or two about energy use on grid-scale. I live in northern Poland, where the climate is marine temperate, so heating is more prevalent than cooling, but the idea seems pretty applicable here as well. Brownouts are already a thing, with an occassional blackout happening mostly because of damage to the grid in rural areas. The generation is almost exclusively coal-based, no nuclear plants, a few wind turbines in the countryside and pretty widespread on-grid solar panels on detached houses. Utility companies offer a few tariffs to domestic customers: flat rate, as well as peak and off-peak with different hours (most common is 1pm-3pm and 10pm-6am off-peak, mine has two more off-peak hours 1pm-4pm and 10pm-7am, a lower off-peak rate for a higher peak one). Off-peak consumption is ca. 75% (I run all major loads off-peak: storage water heater, induction hob, oven, washing machine and dishwasher). We decided to go off gas - it's one less thing to worry about and one less bill (and fixed cost) to pay.
