Gas stoves have reputation for being good to cook with, but they are really quite bad for everything else that happens in the kitchen – like inhaling air. Indoor fas stoves can actually make your kitchen air quality worse than a highway’s. Thankfully, electric stove technology has improved to the point that the cooking benefits of gas are negligible compared to a quality stove.
So if you’re in need of a new stove, go electric.
On the air-quality front, at least, the evidence against gas stoves is damning. Although cooking food on any stove produces particulate pollutants, burning gas produces nitrogen dioxide, or NO2,, and sometimes also carbon monoxide, according to Brett Singer, a scientist at the Lawrence Berkeley National Laboratory who studies indoor air quality. Brief exposures to air with high concentrations of NO2 can lead to coughing and wheezing for people with asthma or other respiratory issues, and prolonged exposure to the gas can contribute to the development of those conditions, according to the EPA. Homes with gas stoves can contain approximately 50 to 400 percent higher concentrations of NO2 than homes with electric stoves, often resulting in levels of indoor air pollution that would be illegal outdoors, according to a recent report by the Rocky Mountain Institute, a sustainability think tank. â€œNO2 is invisible and odorless, which is one of the reasons itâ€™s gone so unnoticed,â€ Brady Seals, a lead author on the report, says.
