Other useful energy saving things have also been invented:
1) The Lightswitch - turn it off when not using the light or in the room.
2) The Door - close it to keep draughts out of the room & maintain the heat in it.
3) Curtains - close them to aid preventing the cooling effect of windows on the room.
4) Foil - Put silver foil behind your radiators - it reflects the heat back into the room instead of into the wall.
5) Ignorance - Don't open the door to visitors - ignore them - lol
Turn the telly off with the switch instead of the standby button. Ditto anything else like the microwave etc
