Originally published in 1982. This book describes a comprehensive and integrated model of the UK energy sector which focuses on decision-making and optimisation rather than on forecasting or simulation. It incorporates the production and investment policy of all the major fuels over a fifty-year horizon and analyses strategy under a variety of different assumptions about costs, demands, technology and future decisions. The chapters cover a wide spectrum of energy problems and policy, including scenarios of rising oil and gas prices, and there are striking calculations of the costs of a non-nuclear plus conservation strategy. Interesting reading for those concerned with energy policy.
