PARIS – A student-built turbine that may someday power Oxford Hills Comprehensive High School’s outdoor sign is one of the items being displayed at Saturday’s green energy fair.

The fair will be held at the school on Route 26 from 10 a.m. to 1 p.m. It will focus on affordable innovative conservation methods and alternative and renewable energies such as geothermal, solar, wind and biomass.

“I’m very interested in promoting green and energy renewable things,” said Alissa Leonard, a high school senior from Harrison.

Leonard came up with the fair idea while talking with a teacher about her senior project. Each senior must create a project that benefits a group or person and gives back to the community.

“Hopefully, people will learn some cool things from it,” Leonard said.

The fair will include booths manned by Katharine Roux from Efficiency Maine and Tom Seekins from Siemens Building Technology, who will have materials on energy efficient appliances, along with other informational booths.

Leonard said she is also working with Gray-New Gloucester High School students who will be providing visual aids to the energy fair. Those students are also having a green fair, she said.

A solar panel built by senior Sawyer Golden will also be on display.

He is a member of the school’s Team Green Club, which is in the process of constructing a turbine that may eventually power the high school’s message board beside Route 26. The turbine will be 25 to 30 feet tall and be powered by a car alternator. The blades for the equipment were just cut and other parts are being assembled with the help of Dave Marshall, SAD 17’s building and grounds facility director.

The group will have to file for a building permit with the town in order to put it up, she said.

The fair is free, but donations will be accepted for the Team Green Club, which was started this school year under adviser Scott Currie.
