Decrease in Electricity Intensity From Increased Efficiency and Changed Product Mix

摘要

In this article, we examine the determinants of improvements in US manufacturing electricity intensity 1998-2010, via decomposition and regression analysis. Decomposition analysis finds both structural change and efficiency improvements played important roles in intensity improvements, with results varying by region. One implication is that improvements in electricity intensity should not be assumed to come only from efficiency improvements: it is important to attempt to understand what drives efficiency improvements and structural change.
