The U.S. propane market is highly seasonal: about two-thirds of the propane consumed last year was consumed in the winter months (October through March). In the United States, most propane is consumed in homes during the winter; about 5% of U.S. homes use propane as their main heating fuel. In its latest Short-Term Energy Outlook (STEO), the U.S. Energy Information Administration (EIA) expects 5% more U.S. propane consumption this winter compared with last winter, largely because a cooler winter forecast means more demand for residential space heating.
