Abstract: According to IEA estimates, about 19% of the electricity used in the world is for lighting loads with a slightly smaller fraction used in the European Union (14%). Lighting was the first service offered by electric utilities and still continues to be one of the largest electrical end-uses. Most current lighting technologies can be vastly improved, and therefore lighting loads present a huge potential for electricity savings. Solid State Lighting (SSL) is amongst the most energy-efficient and environmentally friendly lighting technology. SSL has already reached a high efficiency level (over 276 lm/W) at ever-decreasing costs. Additionally the lifetime of LED lamps is several times longer than discharge lamps. This paper presents an overview of the state of the art SSL technology trends. SSL technology is evolving fast, which can bring many advantages to the lighting marketplace. However, there are still some market barriers that are hindering the high cost-effective potential of energy-efficient lighting from being achieved. This paper presents several strategies and recommendations in order to overcome existing barriers and promote a faster penetration of SSL. The estimated savings potential through the application of SSL lighting systems in the European Union (EU) is around 209 TWh, which translates into 77 million tonnes of CO2. The economic benefits translate into the equivalent annual electrical output of about 26 large power plants (1000 MW electric). Similar impacts, in terms of percentage savings, can be expected in other parts of the World.
