There are plenty of worrisome trends when it comes to
Achieving Sustainability but when it comes to lighting the trend is stunningly good--
electricity use is falling precipitously.
As we explored previously, this trend has been driven entirely by improved technology and not changed household behavior. But what is really exciting is that further technological advances are widely expected to accelerate this positive trend. This new technology, LEDs are clearly the future. So should we wait for it to arrive, or should we take action today?
In this piece we will NOT examine whether
LEDs are a good investment, or how they could
drive the adoption of sophisticated lighting control, or their knockdown positive impacts such as dramatically less waste heat or decade long lifespan. Rather we will only look at the potential impact of LED on one area--electrical consumption--which is quite clearly the area that for lighting and Sustainability we should be most concerned.
I built the following infographic to explore the impact our household lighting currently has, the great future advanced LEDs offer and why we don't need to wait for them to arrive to have a huge impact. Download
it as an image file, or
view it online.
These numbers are based on
the DOE's 2010 report from which I constructed an average American home from which to base my analysis. I presumed that currently CFLs produce an average of 67 lumens per watt and LEDs 83 lumens per watt but current trends suggest
that LEDs are now beginning to significantly diverge from CFLs. LED bulbs currently on the market are highly variable in terms of their efficiency: for a standard bulb anywhere from
60 lumens/watt to
95. Buyer beware.
So in conclusion, LEDs are the future but don't just wait around for them to arrive. The CFLs and LEDs of today can dramatically slash are energy use in your home. BONUS: Just do it once and you can forget about changing bulbs for years and perhaps decades!

The Series: Achieving Sustainability in Lighting
Aaron Redman is the founder of Achieving Sustainability and what passes for an administrator in these parts. Currently he is working on his Sustainability PhD at ASU while raising a baby daughter and taking advantage of nap time to foment discussions on this here blog.
Aaron – You are awesome! I don’t know how you find the time to do all these amazingly researched posts and snazzy infographics! We recently changed out all the lighting in our living room and back bedroom to LED. Glad to know that it was def. a good move!
Yay! There is so much in Sustainability where it is hard to figure out the “right” choice (e.g. food) or the technology is really not fully there yet (e.g. transportation) so it’s nice to find a thing like lighting where the choice is pretty clear and definite.
Also thanks 🙂 Hope I can keep it up!
