Energy consumption
has been steadily decreasing due to increased efficiencies of central
heating boilers and car engines, and to a lesser extent, improvements
in electrical devices such as TVs and light bulbs. The reduction in 2009 was caused by the recession in which businesses, especially those involved in manufacturing, reduced their activity.
The amount is ‘gross’ because
it includes losses such as those in transmitting electricity on power
lines. One TWh (terawatt-hour) is a billion kWh (kilowatt-hour). Running Scotland's entire society in 2014 consumed 155 TWh of energy which equates to about three standard 1 kW electric fire bars being left on for the whole year for each person in Scotland. This would be yet higher if we were to include energy consumed in the production of imported goods and services.
Renewable energy has
increased from 4% of the total in 2005 to 15% in 2014. This is in
part because the total has decreased, but also due to the rapid
growth of onshore wind farms which have tripled renewable electricity’s
contribution between 2005 and 2014. Renewable energy is mostly electricity at 12% of total consumption with biofuel transport and renewable heat consumption making up 3%.
By final use, 53% of
energy consumption involves burning fuels directly for heating, 25%
is burned for transport, and 22% is used as electricity.
