In reply to Nick Smith - UKC:
Cool, I start with an empty kettle, put a mugful of water in it and somehow I usually get a mugful back out when it has boiled.
I use lettuce, cabbage, sprouts, apples, grapes, all green.
Energy efficient bulbs in most lights, seem to get two or three given me every year by some well meaning utilities.
Instant water heater, no tank to fill and cool down.
Visit the pub for a couple of hours to save fuel, well everyone does that I hope, share a bar and heating.
