The Invisible Ingredient in Every Kitchen - New York Times: "Among the major culprits here are inefficient appliances. According to the United States Department of Energy, a gas burner delivers only 35 to 40 percent of its heat energy to the pan; a standard electrical element conveys about 70 percent. Anyone thinking about kitchen renovation should know that induction cooktops, which generate heat directly within the pan itself, are around 90 percent efficient.
