TL;DR: In this paper, a statistical analysis shows that the consumption is sensitive to small changes in climatic variables, particularly the temperature, which is closely linked to the growing diffusion of electric appliances for environmental controls.

TL;DR: In this article, the authors present a survey on the application of growth curves to energy studies, including energy resource analysis, energy demand modeling, fuel substitution, and energy technology development.

TL;DR: In this paper, the authors presented a method for isolating the effect of interfuel substitution such that the change in energy consumption is decomposed into four separate components: changes in production level, product-mix, and sectoral energy intensity.
