My wife and I received an electric kettle as a wedding gift and it's pretty amazing how fast it brings water to a boil. But, she may end up taking it to her office at work as she has no stove there whereas we have a really nice gas stove at home. I have not run the calculation as to if the electricity or the gas costs more to bring a 1/4 kettle of water to a near boil. But to be honest, most of our hot water drinks are coffee so the 12 cup drip coffee maker or even the Mr. Coffee espresso maker, both of which are electric get used far more.
