BALLWIN, Mo. — The official school color at Parkway West High School isn't green, but it might as well be.
That's because the school just completed an energy-efficiency overhaul, changing out light bulbs, revamping the heating/cooling system and installing smart thermostat technology in every room.
"We have tons of students here. It's a huge school, so having that magnitude of change happening here is really wonderful for our community," said Zoe Rutledge, a sophomore who also started the school's environmental club.

Not only will the changes save the school thousands in energy bills, but it also received about $250,000 in rebates from Ameren Missouri for completing the changes.
"If you can change a light bulb, you can save energy," said Ameren Missouri's Bill Davis.
ENERGY STAR estimates that replacing your home's five most frequently-used lights with ones that are energy-efficient can save you $75 each year.
