Natural gas has long been the national preference for residential heating fuels, but electricity has taken the majority of the market share while hydrocarbon gases have been in decline, according to a recent report by the Energy Information Administration.
A portion of the change can be attributed to population migrations to the Western and Southern regions of the country. The Northeast, however, is an exception as natural gas and electricity have both had increasing shares in the market while distillate fuel oils and kerosene have seen a decline.
The majority of homes heated by natural gas are located in the Midwest. The area also has the highest number of homes heated by propane, but both propane and natural gas have been losing market shares to electricity since 2005. The South remains the only region where electricity is the main source for heating homes.
