The worldwide growth in the volume of transport is giving rise to increasing concern over the consequent increase in emissions. The rise in CO2 emissions is hindering the drive to minimize the 'Greenhouse Effect' and other more noxious emissions are causing a deterioration in urban air quality. Urban transport is estimated to account for over 20% of total CO2 emissions in the USA, of which up to 50% is due to energy wasted in braking. The figure worldwide could well be approaching this. Assuming that 60% of this energy is recoverable through regenerative braking, it is possible that total global CO2 emissions could be reduced by 4% by implementation of currently available brake energy recovery technologies. The reduction in other emissions could be far more significant due to the optimized engine management systems which such technologies allow. This paper describes brake energy recovery technologies, and their introduction so far, in comparison with other measures such as use of alternative fuels.
