To say energy efficiency is vital for human welfare is a truism. Developed and developing nations may quarrel over targets linked to carbon emissions reduction. But neither doubts it must contribute to realising such cuts by conserving energy. However, going by a recent study, achieving greater energy efficiency may be a waste of time courtesy its 'rebound effect': a proportionate rise in energy demand. US think tank Breakthrough Institute suggests the gains registered as energy savings could thus be erased, and carbon emissions actually increase. For, higher energy efficiency seems to boost rather than trim energy consumption.
