You can save some money or if not a substantial amount over the year if you can effectively tap into the cheaper bracket of your electricity tariff. We have been urging Mr Washy to do so. He lives in a climate country and it is dark 3 quarters of the year. So why not learn about a cheaper tariff bracket and make use of it? The savings could buy him a weekend trip to somewhere near.
BASIS OF ELECTRICITY RATES by Wikipedia
Electricity "tariffs" (a term that implies a certain market structure, generally that of a regulated monopoly) vary all over the map, even within a single region or power-district of a single country. In standard regulated monopoly markets, they typically vary for residential, business and industrial customers, and for any single class, might vary by time-of-day or by the capacity or nature of the supply circuit (e.g., 5 kW, 12kW, 18 kW, 24 kW are typical in some of the large developed countries); for industrial customers, single-phase vs. 3-phase, etc. If a specific market allows real-time dynamic pricing, a more recent option in few markets to date, prices can vary by a factor of ten or so.
