There's nothing wrong with electric kettles, in fact they're probably the most energy-efficient way of boiling water. I've taken to boiling the required amount of water in the kettle when I boil rice or anything similar. It's much faster, too. It's also a good idea to boil a full kettle once in a while, and pour the remaining boiling water you don't need down the drain. It helps break up fat deposits and kills bacteria that cause bad-smelling drains, and the environmental impact is much less than using drain cleaner. And for the love of your drains, don't pour grease in there!
