DOE Releases Lighting Report
The Department of Energy has released a comprehensive report on the state of lighting in the US. It breaks up lighting energy use by light source type and market segment.
Some Key Points:
- Lighting makes up about 19% of Total U.S. Energy use at 700 terawatt hours.
- Over the 10 years about a billion more lamps went into active service from roughly 7 billion to over 8 Billion.
- U.S. Lighting has gotten more effiecient in 2001 we averaged 45 lumens per watt in 2010 it was 58 lumens per watt. This is attributed mostly by the reduction of incandescent lamps in favor of CFL and better linear fluorescent technology.
Two things really jumped out at me.
First, roughly a quarter of all US lighting is still incandescent, mostly in the residential sector.
Secondly, LED barely registered on the overall chart in 2010. The potential for a vast improvement in sustainable lighting is remarkable.
When this report is released again in 2020 I imagine the two major trends will continue to...more demand for light and increased efficiency. Take a look at the summary report.
