Natural gas is the most diversified fuel in the United States. This domestic fuel is used to cook food, fuel vehicles, generate electricity and as a raw material for products such as fertilizer and plastics. One of the most important uses of natural gas is to heat buildings and homes. About half of all U.S. homes use natural gas as their main heating source.1 This use results in significant seasonal variations in which natural gas consumption is highest during the winter time and lowest during mild-weather months. Natural gas storage enables supply to match demand on any given day throughout the year by adjusting to daily and seasonal fluctuations in demand while natural gas production remains relatively constant year-round.
