According to Mark W Tebbutt 2017-06-03: "Induction hob has lower carbon emissions than a gas hob when power grid ≥400gCO2 per kWh" and the rolling GB grid average is currently ~300gCO2/kWh.) Unlike ceramic or gas hobs that heat the entire pot or pan which in turn transfers the heat to its contents, electric induction hobs heat the ingredients directly using the invisible powers of magnetism. In fact, with the induction system, the pan itself becomes the heat source or element – electromagnetic waves magically penetrate the base of the pot and begin to agitate the electrons in the ingredients, which in turn creates heat for cooking. Those are good –often very good –but in my experience, pans made entirely from stainless steel or cast iron are the best types of cookware for induction hobs.You can position them where you like, the hob 'burner' size is less important and they're less hassle all round.

SMAKLIG IKEA induction hob. The move from gas to this was roughly carbon-neutral at the time. As the grid gets greener, the advantage grows.

There were lots (~20) of requests for the hob, including one from someone wanting to be able to cook smelly meals in a different room!

If the hob is especially grubby or shows signs of pot stains that can’t be removed using washing up liquid, try the vinegar and baking soda method. Combine one part baking soda with one part white vinegar in a bowl or spray bottle and apply it to the hob. Leave for 30 minutes, wipe off with a damp sponge and give it a buff with a dry cloth. Job done. Jean is not convinced that the SilverCrest could be used every day as it does not feel totally robust.Induction hobs are extremely efficient, and can usually cook very effectively on settings from 3 to 7 –the lower settings are more for keeping things warm. Use the top settings sparingly, especially boost. Other things you'll have to get used to are cooking on lower power settings than you're used to – see mistake #5, above – or reducing cooking times. Induction may not involve flames, but it can be fierce. This can actually be useful for certain types of cooking, as you can move food to the outer edges so it stays warm but cooks more slowly, while you use the middle of the pan to properly sear more food. However, it can also cause problems if you're not aware of it. The nominal power rating is ~2kW, so comparable with the SMAKLIG (2x2300W induction zone with booster; 3200W; 1x1400W induction zone with booster; 1800W; 1x1800W induction zone with booster; 2500W).
