“…To this aim we will calculate to what extent aggregate energy intensity trends are to be explained from, respectively, shifts in the underlying sector structure (structure effect) and efficiency improvements within individual sectors (efficiency effect). As such our analysis is related to numerous empirical studies exploring the development and determinants of energy intensity, energy productivity, or energy efficiency (see, for example, Berndt 1978, Fisher-Vanden et al 2004, IEA 2004, Mairet and Decellas 2009, Miketa 2001, Mulder and De Groot 2007, Nilsson 1993, Park et al 1993, Schipper and Meyers 1992, Sue Wing 2008, Taylor et al 2010, Unander 2007, Worell 2004.…”
