And I can see why they say that. Because the first thing I did, after clipping the sensor around the wire between the meter and the fusebox, was wander around the flat turning lights off and trying to get our electricity usage down to zero.
It turns out that the biggest thing I can do is turn off the TV and Amp when I'm not watching TV. That'll save me 1.5p/hour, right there.
The biggest thing I _can't_ do is turn off the fridge-freezer, which seems to gulp down electricity by the bucket load.
It seems that having the internet router/wireless use negligible amounts (the meter goes down to 0.01kW, but it didn't even register the router being turned on and off), so I shall cease worrying about that. Turning off lights as I leave the room is worthwhile though.
And so does replacing the fridge/freezer when we redo the kitchen, which is slated for next year. We'd been semi-planning to anyway, because it's noisy and clunky, but this moves it up the priority list.
I have a score to minimise, so now I am obsessed!
