Testing for Barriers to Energy Conservation -- an Application of a Vintage Model

Alan Ingham, James Maw and Alistair Ulph

Year: 1991
Volume: Volume 12
Number: Number 4
DOI: 10.5547/ISSN0195-6574-EJ-Vol12-No4-3

Abstract:
In this paper we use a sophisticated vintage model of the production structure of the U.K manufacturing sector to analyze the pattern of energy conservation over the period 1971-1987 and to test whether there is evidence of significant market imperfections which could act as barriers to energy conservation.



Technology Diffusion in Energy-Economy Models: The Case of Danish Vintage Models

Abstract:
Technological progress is an important issue in long-term energy demand projections and in environmental analyses. Different assumptions on technological progress and diffusion of new technologies are among the reasons for diverging results obtained using bottom-up and top-down models for analysing the costs of greenhouse gas mitigation. This paper examines the effect on aggregate energy efficiency of using technological vintage models to describe technology diffusion. The focus is on short- to medium-term issues. Three different models of Danish energy supply and demand are used to illustrate the consequences of the vintage modelling approach. The fluctuating utilisation rates for power capacity in Denmark are found to have a significant impact on average fuel efficiencies. Diffusion of electric appliances is linked to economic activity and saturation levels for each appliance. In the sector of residential heat demand, fuel price increases are found to accelerate diffusion by increasing replacement rates for heating equipment.
