Climate change and increasing energy prices threaten the planet and the economy. The European Union has promised to take the lead, through a reduction in greenhouse gases by 20 to 30% and a 20% energy savings by 2020. In this context, the EU is about to ban some of the most inefficient lightbulbs for everyday. Lighting would set the limit at the level of CFLs/LEDs (most energy efficient existing lamps). The energy savings would be maximized, the target is 86 TWh of electricity saved per year in the EU by 2020. To discover how to use different materials in this technology is a high-priority as it shows the advance; maybe this is the future of lighting.
