Due to the high level of energy consumption (and in resulting higher carbon footprint) incandescent lamps have been found unsustainable and already banned by the European Union. In the United States, the Energy Independence and Security Act proposes banning all 100 watt incandescent lamps starting from 2012; 75 watt will be withdrawn from the market in 2013 and 60- and 40 watts in the next year.
In the race toward finding an environmentally friendly replacement, LED technology is pointed by many as a winner.
Federal and states governments encourage businesses and individuals to switch to highly efficient LED lamps. A good example is the city of Cleveland (Ohio) ‘LED Lighting Initiative for Jobs and Economic Sustainability’ program. The city council made a commitment to purchase LED lights from local manufacturers to reduce the city’s energy consumption and carbon footprint and to boost local jobs growth.
Over 4,200 LED lights have been installed in the Pentagon. Other public institutions are also switching to LEDs. Corporate organizations have joined this trend and many of them are currently implementing plans to change all lights across their property portfolio for more efficient options. LED lamps are also becoming a preferred choice for individual consumers.
According to some industry experts, LEDs represent the most important development in lighting history since the invention of the electric light in the last century.
LED technology will play a significant role in the national energy security program. The U.S. Department of Energy has estimated that if LED technology is widely adopted, the electricity used for lighting in the country can drop by 50% by 2020. This achievement will result in a 10% reduction of the overall energy consumption and reduce carbon emissions by 28 tons.
We can expect that LED lighting will become a standard source of light for most lighting application in the next years.
