ABSTRACT
The first is the construction of economic models of energy demand. A fairly well-established set of methodologies that concentrate on future energy demand has emerged as a side product of efforts by economists to model the economy in general. They attempt to explain that demand by means of statistical relationships between it and, for example, incomes or fuel prices. Models on that basis are quite good for identifying such relationships in the short run, but the further you push into the future the more problematic such modelling becomes. In its cruder forms, that approach does not give a good indication of the role which particular energy-using or energy-producing technologies might play.
