The idea is to reduce energy use, but how does work if the vacuum
cleaner has to be passed over the same area more often to pick up the
dust? The EU is also on planning to reduce the power of other domestic
devices, including kettles. Now if I wish to boil, say a litre of water
that, is at say 20 degrees C, surely it will take the same amount of
energy whether I do it with a low wattage or high wattage device. Or am
I missing something here?

Yes, you will use *more* energy doing the job with a lower power
kettle due to the increased losses through the skin of the kettle due
to it being hot longer.

Exactly.

Exactly what though? Is anybody proposing lower power kettles?
