In the last 30 years, specific primary energy use in the German steel industry has decreased by about 30%. This decrease can be attributed to both structural changes in the steel industry (from basic oxygen steel to electric arc furnance steel) and to the improved energy efficiency of new technologies within these technological paradigms. In this paper, the relevance of various determinants for the diffusion of electric arc furnance steel (structural change) and for the energy-use of new technologies in the German steel industry sector is assessed econometrically. The empirical findings support the hypotheses that the diffusion of electric arc furnane steel is accelerated by enery and material input prices and dampened by path dependencies. The findings further suggest that the energy performance of new technologies is affected by energy and material input prices, by expenditures for research and development, and - for basic oxygen steel - also by industry concentration.
