| Introduction This is the thirteenth issue of Energy Balances and Electricity Profiles published by the Statistics Division of the United Nations Secretariat. The publication is availabe in two formats: PDF version and Printed version Like previous issues, this 2004 volume presents energy data for selected developing countries (1) in a single unit of measure, making possible the comparability within countries and commodities. It is in a format which shows the overall picture of energy production, conversion and consumption for fuels utilised in the country. Such a publication is useful in assessing and analysing production and consumption patterns in detail on an internationally comparable basis. |

Since the Statistics Division began publishing energy balances, it has adopted the matrix type of overall energy balance that shows energy sources in the columns and energy flows in the rows (see a sample). The format is described in detail in the technical report entitled Concepts and Methods in Energy Statistics, with Special Reference to Energy Accounts and Balances(2) and is also discussed in the publication, Energy Statistics: A Manual for Developing Countries(3). The level of detail of this matrix structure takes into account the need for disaggregation of the energy sector and final demand, while at the same time, owing to the limitations in the quantity and quality of the currently available energy information, coverage has to be restricted to the main sectors only. Furthermore, it should be recognized that unlike national energy balances designed for individual countries' various specific needs, the energy balance format of the Statistics Division has to accommodate the whole spectrum of national energy data which it receives from national statistical offices and through official national publications. The electricity profiles provide detailed information on production, trade and consumption of electricity, on net installed capacity and the thermal power plant inputs and efficiencies. World energy data is published by the Statistics Division
in the Energy Statistics Yearbook
(formerly the Yearbook of World Energy Statistics). The Yearbook
contains annual data on production, trade, stock changes, bunkers transformation and
apparent consumption for individual commodities for approximately 215
countries and areas of the world. Data on the fuel input into thermal power plants may not
adequately cover the fuel used by self-producers of electricity. The
estimated efficiencies may therefore be high. Inputs from other kinds
of fuels that are not listed explicitly are included in the category "others".
Please note that the data contained in this publication may have been revised and therefore differs from the 2002 Energy Yearbook. The information presented in this publication is available in electronic format. Requests for information should be directed to the United Nations Statistics Division. ____________________ 1. Energy balances for developed countries are already
being published on a regular basis by the International Energy Agency
of the Organisation for Economic Co Operation and Development (IEA/OECD). |
