Just how much potential savings exist if every switched to energy efficient lighting? The US Department of Energy (DOE) reports that the potential energy savings of solid-state lighting (SSL) sources could save 1,488 terawatt hours representing over $120 billion at current energy prices between 2010 and 2030.
The report examines lighting inventory and lumen demand, looks at improvements in conventional light sources, and even examines LEDs. In high CRI (76-90) SSL lights, the DOE expects efficacy to go from 64.3 lm/W today to 147.3 lm/W in 2020 and to 176.3 lm/W in 2030.
From a cost perspective, the DOE projects SSL to go from $169.49 per klm today to $5.03 per klm by 2030 for high CRI products. The report makes projections for other CRI ranges and for OLED lighting as well. The DOE report claims SSL can reduce greenhouse gas emissions by 246 million metric tons of carbon over two decades.
