The U.S. Department of Energy (DOE) just released a report that details the savings gained from switching over to energy efficient LED lighting by the U.S. market. The report, entitled Adoption of Light-Emitting Diodes in Common Lighting Applications, breaks down the 2012 cost savings of the following categories of lighting.
|Indoor lamps (residential)||Indoor luminaires (commercial)||Outdoor luminaires (industrial)|
|1. A-type2. Directional
|5. Downlight6. Troffer (overhead office fixtures)
|8. Streetlight9. Parking lot/garage|
The report states that in 2012 approximately 49 million LED lights were installed in the U.S., saving about 71 trillion BTUs equaling $675 million annually. The report goes on to assert that, if the entire lighting base were to convert to LEDs, the cost savings could be as high as $39 billion.
The illustration below (Figure ES .1) shows the sources of the 2012 energy savings (pie chart) and the potential savings (bar graph) should there be a complete conversion to LEDs. Interestingly, the biggest opportunity for LED penetration is in the area of troffer lighting – those square overhead office fixtures that currently use fluorescent tube lighting.
