Since 1992, OES has been designing, installing and maintaining a large variety of energy conservation and renewable energy systems for homes and businesses.

Whether it's a high efficiency lighting system for a multi campus public school system, a small solar array for a hunting cabin, or a wind turbine big enough to offset a portion of a factory’s energy bill, we've done it.

Can Going Green Save You Green?
“Going Green” is more than the latest buzzword at OES - it is our mission.
