Natural Gas Facts

Natural gas volume

In Canada, volumes of natural gas are typically measured in cubic metres.

  • One cubic metre is about the space taken up by a standard kitchen refrigerator.

In the U.S., volumes of natural gas are usually measured in cubic feet.

  • One cubic foot is equivalent to the area inside a microwave oven.
  • Volumes of natural gas produced or sold are usually reported in millions, billions or trillions of cubic metres or feet. A typical well in Canada would produce 9,600 cubic metres of natural gas per day. A similar well in the U.S. would express its production as 338,800 cubic feet per day (or 338.8 Mcf per day)

Natural gas energy value

Natural gas energy value is typically measured by gigajoules; in the U.S., it is measured in British Thermal Units (BTUs).

  • One gigajoule is one billion joules. The amount of energy consumed each year in a typical Canadian home is equivalent to 120 gigajoules.
  • One BTU is 1054.615 joules, equivalent to the amount of energy released by completely burning one wooden match.

The amount of energy represented by one gigajoule is equivalent to about 30 litres of gasoline, 39 litres of propane, 278 kilowatt-hours of electricity or 45.5 kilograms of coal. The average home in Alberta uses about 120 gigajoules of natural gas per year. Examples of average energy consumption for standard household appliances include:

  • 40 gigajoules a year to heat a 40-gallon hot water tank for a family of four.
  • 4.3 gigajoules for a gas dryer processing 400 loads of laundry a year.
  • 4.2 gigajoules a year for natural gas range used two hours per day.
  • 3 gigajoules for a gas barbecue used 100 hours per year.
