Energy Savings

By simply replacing all ILs with energy efficient compact fluorescent lamps globally, 409 TWh (Terawatt hours) per year would be saved, which is approximately 2,3% of the global electricity consumption. This is equivalent to the combined yearly electricity consumption of the United Kingdom and Denmark. In order to compare the estimated savings with other common units, 409 TWh of savings would be equal to 35.1 Mtoe (million tons of oil equivalent) savings. In terms of energy savings among the main two groups of UNFCCC signatories, Annex I countries would stand to gain around 54% of these energy savings and Non-Annex I countries around 46%.

By way of comparison, the yearly savings in electricity derived from the simple replacement of ILs for CFLs would save enough electricity to close 136 medium sized coal-fired power plants of 500 MW each.
