Longhorn Lights Out

Summer Blast! July's Longhorn Lights Out (LLO) is going to be jam-packed with FOUR chances to win LLO t-shirts, magnets and the Summer Grand Prize of a 60-quart Longhorn cooler and koozies! Instead of one Friday in July, we'll have LLO every weekend in July! Simply register and tell us how you've gone unplugged in your work space. Since it's the last blast--the last official LLO event until the fall semester in September--let's make it count!

Our Volunteers Make a Difference!

The success of Longhorn Lights Out (LLO) requires the efforts of many people on our team. And that includes our amazing volunteers, whose commitment and enthusiasm is unmatched!

For the April 2014 LLO, we collaborated with Engineers for a Sustainable World (ESW) as we led a team of 33 volunteers, representing seven colleges at the university, to assist in reducing loads in common areas. Our teams turned off 4,080 light switches, 6 projectors, and 36 computer monitors in 28 buildings.

Longhorn Lights Out volunteer opportunities for students will return in the Fall 2014 semester.
