Yes, probably too many
but only a problem when they're in use!
There's a lot of criticism of gadgets and this is true in some cases - powered machinery for something that can easily be done manually - sheer laziness.
However some gadgets - particularly in the kitchen - can save energy. We make our own bread with a bread machine which, of course, uses quite a lot of energy but it's a lot less than I used to use making bread manually: for a start, in the winter, we used to have to warm the kitchen up just to get the dough to rise; then turn on the oven for fifteen minutes to achieve the cooking temperature! Much less energy involved in a discrete, insulated breadmaker.
So we shouldn't knock all gadgets - some are energy saving ....
