Can a tumble dryer really kill the planet?

Our tumble dryer broke last weekend - the drum stopped turning and there was a smell of burning rubber. I seriously considered not replacing it - after all we are always being told not to use them - dry your clothes outside (not in this part of the country where it's always raining), get a clothes horse (my kids would soon have that on the floor and anyway, where the heck would I put it?) or use the radiators (have you noticed how stuff that is dried on the radiator ends up feeling like cardboard?). No-one ever mentions the fact that one you have used one of these methods to dry your clothes, use of the steam iron is then compulsory to remove that cardboard feeling.
So all you eco clever clogs out there...which is worse the tumble dryer or the steam iron? After just 4 days without a dryer and therefore almost without a washing machine (no point washing if you can't dry and yes it has been raining almost all week) I've decided that in a house with 3 children, a tumble dryer is ESSENTIAL.
So how did I rescue my green credentials? I went to espares.co.uk and ordered the spare parts needed to fix the tumble dryer. Cost? About £25 and in a couple of days time the Dryer will be like new and I will be happily drying all the clothes by machine again.
Tumble Driers have very few parts and almost all of them are easily accessible once the back of the machine is off. SO, if your tumble dryer breaks - at least think about repairing it yourself. It isn't hard (not if I can do it, it isn't) and it's got to be better to repair than fill a landfill site with a large hunk of metal.
