How heating problems compare among the 15 largest metros
Snow in Chicago’s Millennium Park.
The residents of more than 11 million American homes were uncomfortably cold for at least 24 hours last winter, according to the Census Bureau. That’s about 9% of all households.
While the five metropolitan areas with the largest share of households left in the cold included typically wintry cities such as New York and Detroit, two Texas metros topped the list. That came after the state’s power grid failed during a storm in February.
Climate change has generally made the country warmer, but winters can also bring increased snowfall during snowstorms. Research shows a link between the warming Arctic and worse cold snaps. The winter of 2021-2022 was the second year of the La Niña weather phenomenon, which is when the waters in the central and eastern parts of the Pacific Ocean near the equator cool to below-normal averages. Climate change may be making the phenomenon more frequent and more intense.
The country is trying to move away from fossil fuels to renewable electricity sources, including heating, to counter climate change. American Home Shield examined data from the Census Bureau’s 2021 American Housing Survey to determine which of the 15 largest metropolitan areas had the highest shares of homes with heating problems last winter. To be included, the breakdowns had to have lasted six hours or more. Note that reasons for heat disruptions may not add up to 100%, as more than one category may apply to a unit. Data listed as “not available” was omitted because raw estimates were withheld by the Census Bureau if they did not meet survey standards, or to avoid disclosure.

In late January 2022, a rare freeze warning was issued for South Florida, including Miami, Fort Lauderdale, and West Palm Beach, with temperatures dipping below 32 degrees Fahrenheit in some inland areas and hovering from the mid-30s to near 40 at the coast. Palm Beach County prepared to open warming shelters, which it does when temperatures fall to 40 degrees or less for four consecutive hours or more.
Landlords in Florida must provide heat in the winter when many homes rely on electric heat pumps. As of 2017, natural gas provided three-quarters of the state’s electricity supply, almost double the national average; Florida generates 5% from renewable sources.

— Equipment breakdowns: 58.4%
For Arizona overall, the La Niña weather phenomenon for the second year in a row meant a lack of rain and snow and drier-than-average conditions. The same was true for the entire Southwest. The Phoenix area, including Mesa and Scottsdale, did have some cold snaps: A cold front passed through in December 2021, for example. The National Oceanic and Atmospheric Administration had predicted above-normal temperatures but temperatures were near normal or below. La Niña is likely to persist throughout the winter of 2022-2023.
More than two-fifths of the state’s electricity generation comes from natural gas. Nuclear power is also a significant source, while renewable sources account for about 16% of electricity generation. A weatherization program to make homes more energy efficient is available for residents who meet income requirements.

Climate change is severely disrupting California’s weather patterns.
The Los Angeles metro area, like the rest of the American Southwest, experienced the second year of extreme drought in the winter of 2021-2022 and a frigid February. According to the National Oceanic and Atmospheric Administration, La Niña will probably return for an unusual third year in 2022, with warm and dry conditions that could continue at least through January 2023.
Renewable energy sources, including hydropower and customers’ solar systems, supplied nearly half of the electricity generated within the state. Natural gas is the leading source of electricity.

Atlanta and its suburbs of Sandy Springs and Roswell had warmer than normal temperatures as expected, according to the National Oceanic and Atmospheric Administration. Atlanta averages 2.2 inches of snow a year but hasn’t had that much since 2018, though there was a small-yet-measurable amount of snowfall in January 2022.
Landlords must provide heat for those cold days, though renters must continue to pay even if the heat fails, according to the Georgia Department of Community Affairs.
Natural gas and nuclear power account for more than three-fourths of Georgia’s in-state electricity generation. About a tenth came from renewable sources in 2019.

The Washington D.C. area had winter temperatures mostly close to normal, with a particularly chilly February 2022. Experts had predicted a winter in D.C., and the nearby communities of Arlington and Alexandria, with big temperature swings, from frigid mornings to springlike reprieves. Snowfall was below average.
Solar energy and biomass accounted for 59% of the electricity generated within D.C. in 2020, and natural gas for 41%. Some of those breakdowns can be explained by age: Half of all houses that their owners occupy were built more than 79 years ago, according to the National Association of Home Builders.

A winter storm in February 2021 crashed the Texas power grid, resulting in the loss of power to more than 4.5 million homes, including in the Dallas, Fort Worth, and Arlington areas. At least 57 deaths across 25 Texas counties were reported, along with more than $195 billion in property damage, according to the University of Texas at Austin Energy Institute. Most power plants that generate the state’s electricity run on natural gas.
The storm shut down more than half of the consumer electrical supply. The inability of the power plants to operate in the extreme cold was the main reason for the failures.

The February 2021 storm that caused the power grid failure affected Houston, The Woodlands, and Sugar Land. As a result, the Texas Legislature now requires power plants to be better prepared for extreme cold.
The state’s Public Utility Commission is winterizing plants to meet earlier federal guidance, the Texas Tribune notes. But lawmakers did not make the changes to the state’s electricity market that some experts say is necessary. And they did not call for more weatherization of homes.
Texas’ top source for the generation of electricity is natural gas, followed by coal and then wind power.
