Largely to the credit of Brookes, this journal has, over the past few
years, carried a discussion that challenges the complacency of environ
mentalists and others over the role that improvements in energy effici
ency can play as policy tools designed to mitigate the eco-social cost
s of energy production, transmission and consumption. In this communic
ation I will briefly review the main arguments in this debate with the
intention of highlighting their reliance upon a 'self-limiting set of
assumptions' that make any informed analysis of the relationship betw
een people and energy technologies highly questionable. This is partic
ularly the case in the domestic and transport sectors. Here, only a mo
re culturally sensitive investigation of the possibilities and problem
s afforded by various technologies and of the public's growing awarene
ss of socio-environmental problems can support or counter the argument
s raised by Brookes and his adversaries.
