Futures of Personal Mobility

What assumptions are made about the future uptake and use of electric vehicles and car sharing clubs in the UK? Implications for future energy demand and a transition to sustainable transport are identified by this project.


Energy saving innovations and economy wide rebound effects

This project investigates the impact of energy efficiency improvements throughout the UK economy and along international supply chains, as well as using sophisticated multi-sector macroeconomic models to capture a much wider range of economic effects. This new project on economy-wide rebound effects significantly extends CIED’s work and is led by the Centre for Energy Policy at the University of Strathclyde.

Rebound effects in UK transport

While the fuel efficiency of passenger and freight transport has improved, it may have unintentionally increased the number of cars on the road or encouraged the development of larger, more powerful vehicles. What is the nature and magnitude of these rebound effects and their policy implications?

Energy Efficiency may lead to increased energy consumption in China

Improvements in China’s energy efficiency may be associated with increased energy consumption, a new study has found. The study used an exergy-based approach to estimate the rebound effect at the national level. The analysis showed that in China, improvements in energy efficiency may be associated with increased levels of energy consumption overall – so-called “backfire”.  …

Limits to growth or opportunities for prosperity?

Last week, in a hot and crowded room deep within the Houses of Parliament, myself and fellow researchers from The Sussex Energy Group (SEG) and The Centre on Innovation and Energy Demand attended the launch event of the All-Party Parliamentary Group (APPG) on Limits to Growth. The APPG, chaired by Green MP Caroline Lucas and …

How good is your model? Quantifying quality research

Our latest EPSRC-funded research carried out in CIED (and led by SPRU, Sussex) has something new to say about the testing of statistical models. Available now in the journal Energy Economics and authored by Lee Stapleton, Steve Sorrell and Tim Schwanen, you can access the paper here The paper estimates the so-called ‘direct rebound effect’ associated …

How Scotland could make the most of its energy efficiency policies (and why the rebound effect could be a good thing)

CIED project partners at the Centre for Energy Policy (CEP) at University of Strathclyde together with Climate XChange recently held an event ‘How Scotland could make the most of its energy efficiency policies’. Hosted by the Scottish Government, the event presented insights from recent CEP research, including work on household energy efficiency and rebound effects. …

The Multiple Benefits of Energy Efficiency

On Monday 20th April, the International Energy Agency convened a workshop at its headquarters in Paris to discuss the state-of-the-art in evaluating the multiple benefits of energy efficiency. This workshop was attended by around 50 people: evaluators, policy makers and academics from over a dozen countries. The Sussex Energy Group was represented by Lee Stapleton. …
