RT Journal Article SR 00 ID 10.1016/j.erss.2016.08.015 A1 Grubler, A. A1 Wilson, C. A1 Nemet, G.F. T1 Apples, oranges, and consistent comparisons of the temporal dynamics of energy transitions JF Energy Research & Social Science YR 2016 FD 2016-12 VO 22 SP 18 OP 25 K1 technology diffusion; energy transitions; adoption rates AB Benjamin Sovacool (2016) has provided interesting food for thought in asking “how long will it take?” for the unfolding of energy transitions. Historical evidence of “grand” or global energy system transitions taking decades to centuries to unfold contrasted with highly selective recent and rapid examples of mostly incremental technological change make for an engaging argument. But the observed contrasts are due to the apples-and-oranges comparison between transitions that are measured differently, defined differently, characterized by different processes, and explained differently.
