Total final energy consumption
For the period 1970 - 1995 the estimates are derived from statistics of the International Energy Agency (IEA, 1998). The trend for the period 1925 - 1965 is used to scale the data of Darmstadter (1971) for each region to match the 1970 value. An assumption is made that the relative growth in energy consumption for the period 1965 - 1970, has been the same as for the period 1970 - 1975. For the period 1800 - 1925 the assumption was made that inland energy production (derived from Etemad et al, 1991) equaled the consumption, as export of energy carriers was minimal or absent during that period.
Until the 1920s the region of OECD Europe was the largest consumers of energy, followed by the USA. Both were responsible at that time of consuming more than 80% of the world's energy consumption. This percentage dropped quickly after the Second World War and continued to do so to 36% in 1995. Other regions like the Former USSR, East Asia and to a somewhat lesser extent South Asia increased their energy consumption considerable after 1950. The top five of energy consuming regions in 1995 consists of USA (21.3%), East Asia (16.3%), OECD Europe (14.7%), South Asia (8.0%), and F. USSR (8.0%).
