I don’t really get that it will save much energy?
eg
washjng machine and dishwasher - will still go on just at a different time
showers - we have them in the mornings generally anyway
cooking - we will either cook earlier and reheat on gas hob or cook later
charging devices - this will be done earlier or over night
lights - these don’t use a huge amount of power
TV and computers are probably the only things that may cut down usage of but kids will probably download stuff to (pre-charged) tablets and watch that way
so in reality our usage won’t change much and surely everyone else will also be using all the energy pre and post black out too!
also how will people manage now that so many people work from home? Some people no longer have offices to go to. Or work evenings etc.
will street lights etc still work as 4-7 is peak kids walking home/to&from activities etc and dark streets are a safety concern.
what about emergencies? Most phones now rely on power so if no mobile signal/mobile battery dies and house phone not working will there be a surge in deaths from increased emergency response times? Eg I’m have to go miles to find a phone box!
will crime increase with lack of lighting and alarms?
also lots of alarms start shrieking the minute there is a power cut - will we have to spend 3 hours listening to local alarms?
