Energy Content
The energy content of a 30-litre tank of gasoline is approximately one gigajoule
or 0.95 million Btu of energy. A petajoule is one million gigajoules.
On average, Canada consumes about one petajoule of energy every 50 minutes for
all uses (heat, light and transportation) for both commercial and residential use.
