(WHAS11) - The most famous crayons in the world are going green and we're not talking about color!
Crayola has unveiled a 15-acre solar farm which will produce enough energy to make a billion crayons every year.
That's one-third of the crayons the company produces each year.
It's not just crayons that are going green.
Crayola uses recycled bottle caps to make markers.
