If you cook at home (and nearly everyone does), you’re probably looking for ways to reduce the cost of running your stovetop. The truth is, both gas and electricity cost about the same (for cooking purposes). But there is another choice: the induction cooktop.
Induction cooktops are electric powered, but they heat via magnetism. So the cooktop itself doesn’t actually heat, only the pans themselves heat. They are truly remarkable, and are very popular in Europe, Japan, and Australia.
A full cooktop is quite pricey, but you can order individual units on ebay for around $100.
