You mention two considerations: environmental impact and personal risk. Let’s start with the first. It seems a safe assumption that if you sell your Wedgewood you will, as your husband says, be selling to someone who’s in the market for a gas range. Your husband might also note that, because most of our electricity still comes from burning fossil fuels, the relative fossil-fuel consumption of different types of ranges will be affected by how your local electricity is generated. Induction ranges are impressively energy- efficient, but the power plants that juice them are typically far less so.
