The single biggest waste of energy in our house comes from OH using the hot tap unnecessarily.
When I say 'unecessarily', I mean that due to how long it takes for hot water to reach the tap (nearly a bucketful of cold water comes through first), he is actually washing his hands in cold water, but that same amount of hot water is leaving the cylinder and going into the pipes, so is having to be reheated!
There is a lot of hand-washing every day, so that's a heck of a lot of water being heated for no useful purpose whatsoever.
It isn't just hand-washing, of course - there are many other jobs where he uses cold water from the hot tap instead of just using the cold tap, where the water initially coming out is the same temperature.
OH is aware of this, but is totally unable now to change the habit of a lifetime.
