TINMOUTH, Vt. (AP) – Record high oil prices is helping fuel demand for solar power, said officials with businesses attending the 12th annual SolarFest.

A year ago Global Resource Options of White River Junction had 11 employees. Now it has 35, said Sales Manager Bob Lewis. Global Resources sells pre-engineered ready to use systems.

Solar Works of Montpelier is facing similar growth, although on a smaller scale, said Sales Manager Jon Budreski.

Lewis said the cost for residential system can range from about $18,000 to $90,000.

SolarFest is a two-day celebration of renewable energy held on a farm in Tinmouth.

There were dozens of workshops and exhibitors on renewable energy systems, green building, biodiesel, wind and micro-hydroelectric and sustainable living projects.

“This is the best festival we’ve ever had,” said Festival Manager David Pyles.

Pyles said he was expected 4,000 visitors during the two-day festival.
