I did the survey but to be honest it's a bit rubbish for a university level project, and makes assumptions. I don't actually want an app or emails warning me about electricity use - but there isn't an option for couldn't care.
My gas and electricity bill are huge - but modern living simply uses electricity. I work from home - and have 10 monitors, 6 computers and racks of electronics all on 24/7, and their contribution to the electricity consumption is nowhere near what people make it out to be. I have a meter telling me how much power is being used, and it runs around 1-2KW minimum on the display, all the time. My electricity bill for the quarter Sept to Dec was £297, my gas bill £320 - this mainly because the washing machine is in heavy use with four people getting dirty all the time, so the amount of clothes we wash is pretty high. We don't use the dishwasher - this is our cost saving process. Working from home also means lights on in multiple rooms - which use far more than the tiny amount saved by putting things on standby.
I don't like £1200 a year for electricity, but faffing around with an app won't help me at all - working in the dark, with the heating off, in dirty clothes would save me plenty. I really don't care about the environment from this point of view - I'd be happy with nuclear power (what we buy from the French because we don't have enough of our own).
Living is expensive. Do I plug in the 1K Fresnel lights I have plenty of for video - or spend a few thousand replacing them with LED? I'll keep using the old ones at around 12p an hour. Unit cost for electricity is really not that expensive, I just use too much. My TV could be on all day for pennies, yet a couple of washing machine cycles might cost me real money. The time taken to go around turning things off I just can't be bothered with. The media has convinced people TVs and computer monitors are heavy users of power - they simply are not!
