Lights Out Houston

HOUSTON - Houston's skyline changed when dozens of building owners and managers turned off non-essential lights overnight, KPRC Local 2 reported Friday. Organizers of the project said turning off the lights could result in $1 million in energy savings downtown every year. The president of Central Houston, Bob Eury, said, "We are the energy capital of the world, and we'd love to be the energy conservation capital of the world. We have a great opportunity to do it." Organizers said if the lights were turned off citywide, it could result in $5 million in savings -- enough energy saved to power 3,000 homes a year.

Crescent was involved in the effort where 104,000,000 million sf of office space pledged to turn off unnecessary lights on an ongoing basis effective April 25, 2008.
