The UK energy system has experienced radical reform in past decade — privatisation, liberalisation, re-structuring and re-regulation for gas/electricity supply and coal, plus rapid technological change and flexible fiscal policy in offshore oil/gas. Many countries are seeking to travel similar paths, though more slowly (eg USA, EU, Eastern Europe, Latin America, Pacific Rim) and are following UK experience. The conference brings together academics, business economists and consultants to give the first major evaluation from an economics pespective of the extent to which the UK experience has been successful, and how far it might be reproduced elsewhere.
