Why be energy efficient?
There are significant opportunities across the transport sector to improve fuel efficiency, with a range of technologies and innovations such as reducing vehicle weight, alternative drivetrains, improved aerodynamics and alternative fuels.
This section looks at the technology opportunities in more detail. The Road transport, Rail freight transport and Air transport pages on EEX look at energy efficiency opportunities within each sub-sector.
Combining best practice technological improvements can lead to 10–30% savings in energy costs in each of the major commercial transport sectors.
For information on how these opportunities apply within specific transport sectors, see the EEX content on each transport sector.
For information on alternative fuels, see Alternative Transport Fuels.
Road and rail transport technologies
- Fuel for Thought - Potential energy efficiency opportunities in the Australian road and rail sectors 2011
This report catalogues potential opportunities for energy efficiency improvements in the Australian road transport (heavy duty vehicles only) and rail transport sectors. It was designed to supplement energy efficiency assessments undertaken by transport operators involved in the Energy Efficiency Opportunities program.

- US Department of Energy
A comprehensive evaluation of hybrid vehicle technologies, with sections on the basics, available systems, modelling and simulation, benchmarking and other analyses.
- The Potential Contribution of Light-weighting Weighting to Reduce Transport Energy 2006 (Opens in a new window)
- International Journal of Life Cycle Analysis
- PDF 240 KB
Light-weighting of vehicles is discussed in this paper as an effective means of reducing the energy consumption and GHG emissions of air, land and sea transportation.
- SmartWay Technology Program 2011
- US Environmental Protection Agency
SmartWay is a collaboration between US EPA and the US freight transport industry to assist companies in improving fuel-efficiency and cost savings. The website features a range of tips, publications, news and resources for the industry, with international relevance.
Air transport technologies
- IATA Technology Roadmap Report 2013
- International Air Transport Assocation
The purpose of this IATA report was to identify and rank a range of technologies, applicable over different time periods that will reduce greenhouse gas emissions from aviation. These technologies were reviewed for both applicability and their development timeframe.
The roadmap was originally published in 2009, then updated in 2013.
- Overview on Drag Reduction Technologies for Civil Transport Aircraft 2004 (Opens in a new window)
- PDF 1.2 MB
This report by the French Aerospace Laboratory gives an overview of the results obtained during testing of different methods of drag reduction and looks to evaluate the potential gains offered by the different technologies.
