Energy-efficient GaN-on-Si LED lighting

More and more countries, including the US, are phasing out the sale of incandescent bulbs, which offers an increasing market opportunity for energy-efficient LED lighting. President Barack Obama actively supports LED lighting and his Recovery Act legislation included hundreds of millions to support this industry. Clean energy technology such as solar, wind and electric cars, coupled with increased energy-efficiency are the two-prong approach being executed globally to reduce carbon emissions, which are being increasingly linked to global warming and the influx of weather disasters such Hurricane Sandy, which recently wreaked havoc in the US.
