Energy Saving Benefits

By replacing all inefficient lighting globally, 939 TWh (terawatt hours) of electricity would be saved annually - approximately five per cent of global electricity consumption. This is equivalent to the combined yearly electricity consumption of India and Mexico. To compare the estimated savings with other common units, 939 TWh of electricity would be equivalent to 80.8 Mtoe (million tons of oil equivalent) savings. In terms of energy savings among the main two groups of UNFCCC signatories, approximately 56 percent of the savings would be realised in Annex I countries and approximately 44 percent of these energy savings would be in Non-Annex I countries.

The annual electricity savings associated with upgrading all lamps globally to more energy efficient alternatives would save enough electricity to make 252 large (500 MW) coal-fired power plants redundant.
