Is it really so surprising that we don't (as a rule) have electric kettles? I think the reasons are pretty clear.
First, Americans are mostly coffee drinkers, not tea drinkers. The coffeedrinkers are mostly using coffee machines that heat the water for you, so you don't need a kettle to do it. This is true from the low-end $30 drip machine to multi-thousand-dollar espresso machines.
Second, America is on 110, not 220. Kettles in the UK do boil CRAZY FAST, but the electric kettles I've used in the US aren't really any faster than using a stovetop kettle. American tea-drinkers often have those.
