Energy use, population and growth, 1800-1970

In English In this paper, the role of energy use is incorporated into unified growth theory. The paper presents some interesting evidence about the evolution of energy in the transition from stagnation to growth, and it subsequently develops a growth model where the observed increase in conversion efficiency in the coal energy sector is explicitly modelled and calibrated to existing data over the period 1800–1970. The quantitative analysis sheds light on the impact of energy use on the transition from stagnation to growth.
