Remodeling 101: Farewell to the Gas Range


No wonder so many of us like cooking with gas. There’s something atavistic about fixing food over an open flame—a throwback to primitive man (and woman!) hunched over the fire. And gas heat is a snap to regulate—it’s on as soon as you turn the knob; the flame size shows how hot it is; and when you turn it off it’s immediately off. Plus, it’s cheaper than using electricity. If you already cook with gas, you probably don’t need me telling you this.

But as you may have heard, gas ranges are on the way out. In 2019, Berkeley, CA, became the first city to ban gas hookups in most new homes and buildings. Since then, many California cities, including San Francisco and Sacramento, have adopted similar ordinances. Massachusetts and Washington state are moving in the same direction. And in December 2021, in a sign of the times, New York City passed an act banning gas hookups in all new buildings (to take effect in December 2023 for buildings under seven stories; in 2027 for taller structures).

What’s the rationale? Cities want to cut reliance on fossil fuels, as part of our collective effort to reduce climate change.(Electricity is also a fossil fuel, but it can be generated by wind or solar power.)

But there are more reasons for you to swap out your beloved gas stove. Recent reports show that gas ranges constantly leak methane, a greenhouse gas that contributes to global warming. And by “constantly,” we mean even when the stove is off.
It’s no small problem, given that some 40 million US homes (about a third) have gas ranges. An article published in January 2022 in Environmental Science and Technology revealed that “annual methane emissions from all gas stoves in US homes have a climate impact comparable to the annual carbon dioxide emissions of 500,000 cars.”

But wait! We’re not done listing the hazards. While methane gas emissions harm the atmosphere, they don’t cause health problems in humans. It’s the other pollutants commonly emitted by gas stoves—nitrogen dioxide (NO2), carbon monoxide, and formaldehyde—that can harm members of your household, by causing or worsening respiratory diseases. Even at low levels, these noxious fumes are especially dangerous for people who suffer from asthma or chronic obstructive pulmonary disease. And there’s evidence that children living in homes with gas stoves run a 20 percent higher risk of developing a respiratory illness. Remember pilot lights that were always on? Most gas stoves built after 1990 no longer have them, in a change made to reduce emissions. And note that while other household gas appliances—furnaces and water heaters—are required to vent to the outdoors, gas ranges generally are not.

For all these reasons, an electric range is a much wiser choice.

Q: I’m convinced! How do I go about replacing my gas stove?
A: Before you can install an electric range, you’ll probably have to upgrade your kitchen’s wiring. Your gas stove operated on 120 volts, but a new electric unit will require 240 volts. So you’ll need a licensed electrician to run a larger wire from the panel breaker to the kitchen and hook up a new 240-volt receptacle there.

Q: Should I opt for a regular electric stove—or step up to an induction range?
A: There are many reasons to switch to induction cooking. These electric appliances, which use an electromagnetic current to heat pans, are the most energy-efficient option, consuming about half the energy of a typical electric stove with coil burners. They’re also the safest option: they don’t produce excess heat, dangerous flames, or pollutants. What’s more, the burners stay cool to the touch—even when they’re turned on—and distribute heat very evenly. There are a few drawbacks: You must use flat-bottomed pots containing iron (not aluminum or
glass) whose size matches that of the burner. It’s the most expensive option, which could be
why less than 5 percent of US homes have adopted them. And induction ranges still use fossil
fuels to generate power.

Q: I just got a new gas stove and I’m not keen to replace it any time soon. What to do?
A: For starters, maximize ventilation. Always turn on your range hood when you’re using the
stove, and prioritize the back burners, which allow the range hood fan to capture more gases.
Note that to be fully effective, the hood must vent to the outdoors—which isn’t always the case
in, say, an apartment building. [

This will also reduce smoke and grease that result from cooking.
It’s believed that a gas stove’s leaked emissions come mostly from the burner control valves.
Keep the stovetop and burners clean to help minimize this—and make sure the burner caps are
properly positioned (indicated by a steady blue flame). If the burners don’t ignite quickly, call in
a repair service.
Another way to cut indoor air pollution: use your microwave more.
Q: How can I replace my gas stove in an environmentally responsible way?
A: You can’t donate even a functioning gas stove to a good cause, because of the danger of
leaks and the possible presence of mercury (used in older gas ranges to make sure the gas valve
is closed when the pilot light isn’t on). But you don’t want it tossed into landfill. When you buy
a new stove, ask if the retailer will remove your old one when they deliver the new one—but
make sure the company is a certified recycler of old appliances.

If you can’t rely on the retailer, see if your local municipal recycling office will do a curbside
pickup. Other options: locating a scrap metal recycler or certified recycling facility in your area.
