Tulsa County Energy Efficiency Efforts Pay Off

Tulsa County's investment to become more energy efficient is paying off.

On Thursday, Public Service Company of Oklahoma gave the county an incentive check for nearly $150,000 for switching the more than 500 light fixtures at Expo Square to more efficient models.

Crews have been replacing the lights over the last couple of months, at a cost of about $420,000.

The new lights will light up quicker, last longer and not generate as much heat, which will mean lower cooling costs.

County commissioners say the lights will also have a more even color and will be quieter.

The last time the lights had been replaced was in the early 90s.
