Shop Till We Drop
ECEEE Summer Study
Previous literature has established that energy use from the U.S. and global freight sector is increasing both in intensity and absolute terms. Most analyses of freight energy only consider freight up to the retail outlet; however, most goods keep moving until they reach the consumer's home or place of business. In the U.S., driving-for-shopping has increased four-fold per household since 1970, faster than any other driving function. In this paper, I propose a new category called Goods Movement…
Previous literature has established that energy use from the U.S. and global freight sector is increasing both in intensity and absolute terms. Most analyses of freight energy only consider freight up to the retail outlet; however, most goods keep moving until they reach the consumer's home or place of business. In the U.S., driving-for-shopping has increased four-fold per household since 1970, faster than any other driving function. In this paper, I propose a new category called Goods Movement which draws its boundaries around the portion of freight dedicated to retail goods and driving-for-shopping. This new boundary can more accurately capture the impact of material consumption on the environment, and can better analyze the impact of new goods delivery modes, such as the rise of on-line shopping.
I analyze the history of energy use from the Goods Movement system for the past 40 years in the U.S., and decompose the data to establish key drivers. I find that the major drivers in the rise of energy use in the Goods Movement sector between 1967 and 2009 were: increases in population, total retail freight tonnage (especially before 1990), distance freighted per tonne (especially after 1990), shopping trips per household per week (especially before 1995), and distance per shopping trip (especially after 1990). These trends have led to an increase in the intensity of goods movement energy per unit capita, per GDP and retail expenditures, and per store.
Drawing on this analysis, I then present policy recommendations that can slow or reverse these upwards energy use trends. Policy and technological levers to halt this nearly ignored increase in energy use will be more effective if they look as Goods Movement as an integrated whole, rather than as segregated freight and driving sectors.

Smart Transportation: Synergizing Electrified Vehicles and Mobile Information Systems
Environment
This article outlines how smart, mobile information systems can bring cost-effective, low-carbon solutions to the transportation sector. After outlining plug-in vehicle technologies and environmental impacts, we describe several specific ways in which mobile information can accelerate the success of plug-in vehicles. Finally, we show how mobile information systems and plug-in vehicles fit into a wider agenda for sustainable and smart transportation.
