Unusually mild weather across the United States this autumn has sharply reduced heating demand and contributed to the substantial oversupply of both natural gas and heating oil. Heating demand has been 27 percent lower than the long-term average so far this heating season according to the National Oceanic and Atmospheric Administration (NOAA). Temperatures have been above normal every week since the beginning of September and heating demand has been correspondingly lower than usual ( tmsnrt.rs/1X1Y1WK ). The heating season runs from July 1 through until June 30 of the following year. NOAA estimates heating demand by comparing the temperature in each area with a baseline of 65 degrees Fahrenheit, and then weighting the differences by the population. Mild weather has coincided with strong growth in supply of both natural gas and heating oil this year and contributed to a big rise in the amount of both fuels in storage. […]
