p = provisional. — = the source printed no value for that year.
Energy available to a country in the year: production + imports − exports − international bunkers ± stock changes (IEA total energy supply), split by source. The seven sources sum to total energy supply less net trade in electricity and heat, as on IEA's country pages.
