Has my wife gone mad?

[Captaincrunch]

Hi could someone answer this question so that i can print it off and show her?

I went to boil the kettle and in she came like a wailing banshee shrieking "Don't do it!" as if the place was filled with gas and i was about to press an ignition button. I shouted "What? and she said "it's full, pour half away as it'll be cheaper" I laughed and said "It doesn't use up more then 240v at a time so it doesn't matter whether there's a thimble full or whether it's filled to the brim as the kettle can't suck out more electricity from the national grid as the wires are only built to be able to take 240v at a time and unfortunately we don't have a magical device that can do otherwise" She then started harpng on about some advert which she'd seen which honestly put a bee in her bonnet about all of these rubbish "Energy saving" tips which seem to cost quadruple more then the current methods!

Does anyone know whether this really does save money and if so how much money does it cost to have a full kettle boiling 2 times a day every day of the year and how much does it cost to have a half filled kettle 2 times a day every day in a year and exactly what the saving is so i can show the dozy mare when she comes home.

Many thanks for your help!

Of course she is right. You are heating up more water than you need, therefore using up more power than you need to use.

surely it will take longer to boil so will use more electricity. I sometimes put enough for one cup in but always misjudge it and end up boiling it again . lol

I think Captaincrunch is just pulling our legs here.
