LED Lighting Expected to Save Energy, Cut CO2

In June 2004, the Environmental Pollution Control Center of Osaka Prefecture, Japan, published a report on estimated power consumption reductions, focusing on state-of-the-art technology in white light-emitting diodes (LED) as a global warming mitigation measure. The report summarized potential LED lighting applications, forecasts for their future distribution, and estimates of resulting CO2 reductions in a bid to accelerate the development and popularity of LED lighting.

According to this report, which predicts greater popularity for LED lighting, power consumption will continue to increase as long as we keep using current lighting fixtures. With the development and wider application of LED lighting, however, it predicts a decrease in yearly power consumption in Osaka Prefecture in the range of 2.0 to 9.1 percent by 2010, and 7.2 to 16.2 percent by 2015. This would result in reductions in annual CO2 emissions amounting to 51,000 to 230,000 tons in 2010 and 190,000 to 430,000 tons in 2015.

Also, the report notes that, in addition to advantages such as energy efficiency, long operating life and low environmental impact, LED lighting also generates little heat. In view of this advantage, retail and other commercial facilities are seen as a promising area for practical application, due to easier commodity temperature management and reductions in air conditioning costs.
