Energy Sufficiency—Managing the rebound effect

Energy Sufficiency—Managing the rebound effect

New ECEEE concept paper co-authored by CUSP researchers Birgitta Gaterleben and Angela Druckman

The potential for energy sufficiency to reduce energy use and emissions is gaining increasing attention. One reason is that improvements in energy efficiency have not reduced energy consumption by as much as anticipated. This is partly due to various rebound effects—namely behavioural responses to improved energy efficiency that offset some of the potential energy and emission savings.

A new report by former SLRG colleagues Steve Sorrell, and CUSP researchers Brigitta Gatersleben and Angela Druckman examines the nature of these effects, and asks the question: can greater use of sufficiency policies and actions help to tackle negative rebounds, or will it create rebounds itself?

The report explores the relationship between rebound effects and energy sufficiency, using both economics and social psychology and arguing that both these perspectives are needed to fully understand the effects. It looks at the evidence for the nature and size of rebound effects from improved energy efficiency and suggests ways in which energy sufficiency actions could reduce them. It also investigates how energy sufficiency actions can lead to rebound effects of their own and examines how careful policy design can be used to minimise or avoid increased energy use where this is not improving wellbeing.>

Having Your Bit of Cake and Eating it Too?

HAVING YOUR BIT OF CAKE AND EATING IT TOO? 

Downsizing, the film by Alexander Payne, which follows Paul Safranek (Matt Damon) as he decides to shrink himself to 5 inches tall and moves to the downsized colony of Leisureland, had great promise as a conversation starter about sustainability, and in some ways it succeeded, but in many ways it reinforced the same myths society regularly perpetuates.

The film starts as Norwegians successfully shrink living things to just a percentage of their size. Why? It turns out—as the lead scientist Dr. Andreas Jacobson explains in his lecture “Human Scale and Sustainability”—the experiment was conceived in the 1950s in order to deal with overpopulation. They determined that downsizing was the “only practical and humane solution to humanity’s greatest problem.”

Any time sustainability and population play a lead role in a movie—I’m excited. But the film failed in several key ways. Let’s explore how:Rebound Effect

First off, there’s the classic problem of the rebound effect. If a person moves to an area where he can sell off his car and get around by bike, his ecological footprint will shrink. Except, now that he spends less on transportation, he ends up spending those savings on other goods, and in the end may have an even larger ecological impact. This is known as the rebound effect.

In shrinking down to 5”, we’re talking about a reduction in consumption by a factor of 14, assuming Paul Safranek started at about 5’ 10”. This is even better than the Factor Ten reduction called for in the 1990s. Of course, that’s the ideal, not the reality. As people shrink down, their desires grow significantly—in part primed by the marketing of becoming small in order to live large.
