This volume contains data on energy supply and consumption in original units for coal, oil, gas, electricity, heat, renewables and waste.  Complete data are available for 2010 and 2011 and supply estimates are available for the most recent year (i.e. 2012). Historical tables summarise data on production, trade and final consumption.  The book also includes definitions of products and flows and explanatory notes on the individual country data.

In the 2013 edition of Energy Balances of OECD Countries, the sister volume of this publication, the data are presented as comprehensive energy balances expressed in million tonnes of oil equivalent.
