The Energy Statistics Yearbook 2023 is the sixty-seventh issue in a series of annual compilations of internationally comparable statistics summarizing world energy trends. Annual data for 227 countries and areas for the period 2019 to 2023 are presented on production, trade and consumption of energy: solids, liquids, gaseous fuels, electricity and heat, covering both renewable and non-renewable sources of energy. In addition, per capita consumption series are also provided for all energy products, and for the third time a special table on CO2 emissions is published in the Yearbook. Graphs are included to illustrate historic trends and/or changes in composition of production and/or consumption of major energy products. Special tables of interest include: CO2 emissions from fossil fuels, international trade tables for coal, crude petroleum and natural gas by partner countries – providing information on direction of trade; selected series of statistics on renewables and wastes; refinery distillation capacity; and a table on selected energy resources.
