Why does water boil faster in a kettle then on the stove?

[YukiYue]

This is probably a silly question, but it got me thinking. Why does water boil faster in an electric kettle then in a pot on a stove. Is it because a kettle can generate more heat energy? Anyone have any thoughts?

The element in the kettle is surrounded by water - so pretty much all the energy goes into the water.
On a stove only some of the energy goes into the pan, and then only some of this heat goes into the water
