The profile of global energy consumption reveals that the world remains highly dependant on fossil fuels. Over the last 50 years, while the consumption of energy grew substantially, the world undertook a transition in its usage of fossil fuels, from solids (coal), to liquids (oil) to gases (natural gas). While coal accounted for 39% of all energy consumption in 1965, this share declined to 29% in 2008. Meanwhile, the share of oil remained relatively stable, from 40% of energy consumption in 1965 to 34% in 2008.
