HOUSTON -- Houston's skyline changed this weekend 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.

"That's quite a bit of money! What does it do for the skyline of the city?" said Vanessa Pratt, who loves to look at the skyline with her daughter. "I think it's a great idea to save money and energy, I would agree, but as far as the makeup of the city, any major city you go to, that's the first thing you see when you get to the city is the skyline and the lights."

The program runs from Friday through Sunday but organizers hope it's the just the beginning.
