Abstract
Energy balances giving details of production, processing and use by sector have been available for the major economies for thirty years or more. Such balances are provided annually by governmental agencies and by the OECD. No such balances have been available for many non-OECD countries. The flow of information has improved in recent years although there will always be a relative lack of precision associated with the estimates made for traditional and non-commercial fuels (dung, fuel wood, vegetable wastes).
Tackling the problems of faulty or insufficient data is facilitated by an integrated approach, using a standardised matrix of energy supply and demand. A complete energy balance for any one country may take many man-hours to construct, with significant further effort required to update it as new information becomes available.
Examples of energy balances for Kenya and Pakistan have been included.
