So which blithering idiot scheduled 'Switch off fortnight' in the UK for two weeks in the late Autumn? When it's cold enough that every device left 'on' actually contributes to heating our buildings and thus means less work for the heating system to do?
In other words, switching stuff off at this time of year has almost no 'net' effect whatsoever.....
'Switch off fortnight' needs to have happened in the SUMMER term, when dramatic overall savings could have been made.
As a physicist, I sometimes despair..... 8-)
