Living where I do under the arms of a huge electricity pylon just a field away from the edge of suburbia, it was ever frustrating when out aged wooden pole supported local distribution network failed on a semi regular basis during storms etc... Sitting without power looking at the newer housing estate with all it`s lights on.... Shrug. At least early on after moving here, we saw the benefit of the Rayburn coal fired cooker, as well as the back boiler in the coal fire to provide hot water..... All ripped out in time relative to the modernisation process of the home, but the need to be self reliant was not forgotten, candles, Torches camping stove and £3k spent to get a gas pipe laid along the road 40 years ago was money well spent...
As for yet another benefit of EV, if one has an installation such as one`s EV can also be used as a backup power supply....hmm..?
