Induction Cooktops and Ranges
Whether you are concerned about your family’s exposure to indoor air pollution, want more precise temperature control and easier cleanup, induction cooking may be for you.
Like electric cars, induction cooktops and ranges (with oven) take a little getting used to. Translating your familiar dishes and cooking cues to new temperature and time controls may require a few tries. But THESE CHEFS and the one in this NOVA video seem to love them. So do we.
If you’d like to try out induction before committing to a full cooktop (or if you need an extra element for a party or cook in an RV or dorm room) consider getting a portable one or two element burner that can plug in anywhere. Be aware though that these have small elements (which limits the size of your pans and can warp them if they are too wide and thin) and are not as powerful as a full cooktop.
There is an Inflation Reduction Act (IRA) Electrification REBATE for both traditional ELECTRIC stoves and modern INDUCTION stoves (up to $840) for low- and middle-income households available the end of 2023/2024. There are also funds to cover the cost of converting from gas or propane if you need to upgrade an electric panel and/or wiring. There is NO IRA stove TAX CREDIT. It is not yet clear if you qualify for the rebate in New Mexico if you already have an electric stove. See Resources below for more information on incentives.
itself. Because it is done via electromagnetic induction, it affords instantaneous, self-regulated and precise control of the temperature. Induction cooktops can maintain a precise, steady temperature, even at
very low temperatures, e.g., to melt chocolate without a double boiler, which is especially hard for gas. Easy sous-vide! Cooks Faster. Under most conditions, induction cooks faster than gas and electric. Convenience. Once you get the hang of it, you can set a temperature and timer and attend to something else. App-driven cooking. Cool cooktop to put cookbook on. In a power outage, some models come with batteries. Safety. No open flame. The cook surface outside of the pot areas does not get hot. Most cooktops turn down or shut down when the pan gets too hot. The cooktop turns off when the pot is off the stove. Cooler Kitchen. Induction only heats the pot, not the air, unlike gas and electric. Easier Cleanup. Smooth ceramic-glass top that doesn’t get as hot as electric stovetops means easier cleaning. Health. Unlike methane and propane stoves, induction and electric cooktops and ranges do not emit indoor pollutants (see below). However you still need to vent for the gases produced by cooking.

Heath Effects from Gas and Propane Stoves
Fossil fuel appliances emit pollutants of concern to climate and health. Indoor pollution levels from a variety of sources can be 2-5 times higher than typical outdoor concentrations and are largely unregulated. In practice, byproducts of burning methane and propane found in homes and flues include benzene, carbon dioxide, carbon monoxide, sulphur dioxide, nitrous oxide and particulates. (Wood heating and fireplaces and outdoor fires can also create indoor pollutants.) This is why it is very important that all of our gas appliances are regularly inspected and properly vented. In the kitchen, where our families spend so much time, this is especially true. Pollution from gas and propane stoves, such as NO2, can reach levels that would be illegal outside, according to a recent report. NO2 causes inflammation and is linked to a greater likelihood of children developing asthma. In the fall of 2022, the American Medical Association adopted a resolution that acknowledged “the association between the use of gas stoves, indoor nitrogen dioxide levels and asthma.” A December 2022 report published in the International Journal of Environmental Research and Public Health attributed 12.7% of current childhood asthma in the US to gas stove use, a preventable rate, the authors note, that is comparable to the childhood asthma burden attributed to secondhand smoke exposure.
If you cannot afford to switch to electric ranges, toaster ovens and/or kettles make sure to ventilate as much as possible using your stove’s hood, by opening a window while cooking or by running a large air purifier continuously.
How Induction Stoves Work
A high frequency alternating electric current runs through a coil of wire (left) under the cooktop’s ceramic-glass surface. This creates an electromagnetic field that in turn induces electric eddy currents in the electrically conductive material of the cooking pot when it is placed on the surface. The current in the base of the pot heats it up through a process called resistance heating, which is how the elements of an electric stove or coils in a toaster heat up. The heat in the pot then cooks the food inside it. If the pot material is not electrically conductive, no current can flow and no cooking results.
Resources and Rebates
Incentives and What to Know Before You Buy. You may need an electric panel and/or electric wiring upgrade to install an electric or induction cooktop or range that require 240V connections. There are tax credits and low- and middle-income rebates and tax credits for electric panel upgrades and low- and middle-income rebates only for wiring upgrades. IRA rebates for the stoves themselves for low- (100% of the cost) and middle-income (50% of the cost) up to $840 will be available towards the end of 2023.
Look for rebates from your electricity provider, governments, and manufacturers. For example, the Socorro Electric Coop and Central New Mexico Electric Coop offer $100 per unit for electric-to-induction replacements & $350 per unit for gas-to-induction replacement or new construction). As of March 2023, Xcel and El Paso Electric were not offering rebates for cooktops, and they are not covered in the NM State program for consumers. PNM is (July 2023) considering whether to offer rebates.
