Small rural villages in Alaska are expected to save up to 26 million gallons of fuel annually by 2018, thanks to renewable energy, observers say. The state has invested nearly $250 million in small community projects over a five-year period, said Sean Skaling, the state Energy Authority's director for alternative energy. Funding for the state's Renewable Energy Fund program could reach $227 million if Gov. Sean Parnell clears additional $25 million appropriation approved by lawmakers this spring, said Skaling.
