Gas stoves are unhealthy for your family and the planet. Gas stoves emit toxic gases into your house that can cause asthma and other respiratory problems. Gas stoves emit carbon dioxide and methane into the atmosphere which contribute to global warming. Induction stoves use clean electricity — choose 100% renewable electricity from your local community choice energy provider. Induction is also energy efficient: just the pan is heated, with no energy wasted heating the air around it. Induction stoves are 85% efficient, while gas stoves only deliver 32% of the flame heat to the pan.
