This issue of the "Digest of United Kingdom Energy Statistics (DUKES)" is part of a series and updates the figures given in the Department for Business, Enterprise & Regulatory Reform's (BERR) DUKES 2008. The publication consists of seven chapters; the first chapter deals with overall energy, with the other chapters covering specific fuels, combined heat and power and renewable sources of energy. The statistics presented in this digest will generate widespread interest from anyone working within or with an interest in energy sources, consumption and climate change. Chapters covering specific fuels and renewable sources of energy contain details on the production and consumption of individual fuels, presented using commodity balances. A commodity balance illustrates the flow of a fuel through from production to final consumption. These individual commodity balances are also combined in an energy balance, showing the interaction between different fuels. General energy statistics are presented in a table, revealing energy consumption by final users and an analysis of energy consumption by main industrial groups. Surveys conducted by AEA Energy & Environment on behalf of DECC estimate the contribution made by combined heat and power and renewable energy to energy production and consumption in the UK. The following are the key features of this title: energy; solid fuels and derived gases; petroleum; gas; electricity; combined heat and power; renewable sources of energy; energy and commodity balances, conversion factors and calorific acronyms; further sources of UK energy publications; and, major events in the energy industry.
