On 1 January 2010, the United Kingdom had 62.5 million inhabitants. According to the International Energy Agency, the British energy consumption in 2010 was distributed as follows : 5.8 Mtce of solid fuel, 59.5 Mtoe of petroleum, 1 900 TBtu of natural gas, 390 TWh of electricity and 32.5 TWh of hydropower.


  1. Calculate the total energy consumed in 2010 by the United Kingdom in Mtoe.
  2. Convert this result in Wh.
  3. Deduce the energy consumed by an inhabitant of the United Kingdom in 2010 in Wh.

The tonne of oil equivalent (toe) is a unit of energy defined as the amount of energy released by burning one tonne of crude oil.

A tonne of coal equivalent (tce), sometimes ton of coal equivalent, is a conventional value, based on the amount of energy released by burning one tonne of coal.

The British thermal unit (Btu or BTU) is a traditional unit of heat; it is defined as the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit.

The energy unit used for everyday electricity, particularly for utility bills, is the kilowatt-hour (kWh).

The joule  (symbol: J), is a derived unit of energy in the International System of Units. It is equal to the energy transferred to (or work done on) an object when a force of one newton acts on that object in the direction of its motion through a distance of one meter.

1 toe = 41.85 GJ

1 tec = 29.3076 GJ

1 Btu = 1.054 to 1.060 kJ

1 kW.h = 3600 J
