Section 11 – Energy consumption and intensity

Definition of energy consumption for the SHEU-2007

For SHEU-2007, energy consumption is the sum of household electricity, natural gas, heating oil, propane and wood consumption in terms of energy during 2007. For this survey, household energy consumption excludes energy consumed for transportation and gas-powered equipment requirements.

Household energy consumption data for SHEU-2007 are presented in gigajoules of energy.

What is a gigajoule?

A unit of energy

A gigajoule (GJ) is a common unit used to measure energy consumption.

Many types of energy consumption can be measured in gigajoules, including

  • electricity
  • natural gas
  • heating oil
  • propane
  • wood

All of these energy sources are consumed by Canadian households. Therefore, the gigajoule is a useful unit of measure for the sum of various types of energy consumed by households.

A gigajoule in plain terms

One gigajoule is approximately equivalent to the energy consumed by

  • using ten 60-watt light bulbs for eight hours a day for two months
  • the average Canadian personal vehicle in 5.5 days5
  • the average digital television used in Canadian households in a year6
  • the average Canadian household (excluding transportation and gas-powered equipment requirements) in approximately 3.5 days7
