A good eco tip is to keep a litre jug of chilled water in your fridge. Apparently this helps regulate the temperature of the fridge - due to packing a space with something cool! So this is good news for my poor silver Hotpoint in its perpetual half-full state.
But also, it provides well chilled water for drinks (obviously) which in turn prevents the running of the cold tap for a few minutes every time someone wants a glass of squash. And it's so much colder straight from le frigo.
Another plus is that the family will rediscover a love of unblemished H2O - cheap and healthy and a welcome break from endless cups of tea!
This fine specimen of a fridge jug only cost £1.29 from Dunelm so get chilling....
