Why Is The US So Energy Intensive? Evidence From US Multinationals In The UK

At present the USA is - in per capita terms - the top greenhouse gas polluter among the world's major economies. This is mirrored by the high energy intensity of all sectors of the US economy including manufacturing industries. A potential explanation for the higher energy intensity is lower US energy price levels. However, common price elasticity estimates are not high enough to explain the observed differences between countries. Alternative explanations include firstly geographic or other locational differences and secondly firm specific technology differences between US firms and others. This paper explores this latter possibility by comparing establishments of US firms in Britain with other comparable firms thereby ruling out locational differences.
