Oil: All figures are reported to the nearest whole number of thousand metric tons, except where otherwise specified. Natural gas: All figures are reported to the nearest whole number of million cubic metres (at 15 deg C and 760 mm Hg). Coal: All figures are reported to the nearest whole number of thousand (or million) metric tons. Electricity: All figures are reported to the nearest-whole number of gigawatt hours (GWh). Crude Oil: Crude oil is a mineral oil of natural origin comprising a mixture of hydrocarbons and associated impurities, such as sulphur. It exists in the liquid phase under normal surface temperature and pressure and its physical characteristics (density, viscosity, etc.) are highly variable. This category includes field or lease condensate recovered from associated and non-associated gas where it is commingled with the commercial crude oil stream.
