These expressions are often used to describe the total energy supply of a national territory. Secondary energy is a carrier of energy, such as electricity. These are produced by conversion from a primary energy source. Primary energy is used as a measure in energy statistics in the compilation of energy balances, [5] as well as in the field of ...
Petroleum products are materials derived from crude oil as it is processed in oil refineries. Unlike petrochemicals, which are a collection of well-defined usually pure organic compounds, petroleum products are complex mixtures. [1] Most petroleum is converted into petroleum products, which include several classes of fuels. [2]
Each crude oil has unique molecular characteristics which are revealed by the use of crude oil assay analysis in petroleum laboratories. [83] Barrels from an area in which the crude oil's molecular characteristics have been determined and the oil has been classified are used as pricing references throughout the world.

This was the largest decrease of any oil-exporting nation in the world, and has led to Britain becoming a net importer of crude for the first time in decades, as recognized by the energy policy of the United Kingdom. Norwegian crude oil production as of 2013 is 1.4 mbpd. This is a more than 50% decline since the peak in 2001 of 3.2 mbpd.
