On a clear, sunny day in June, Joe and Janice Banta stood in their driveway in Anchorage, awaiting a truck full of solar panels. At midday, most of the roof of their two story house was illuminated with sun, enough for two rows of panels. “It’s a sound investment.” Joe said, “We wouldn’t do it if it didn’t make sense.” The Bantas are self-described enthusiasts of renewable energy. A single solar panel is mounted to the roof of the small fishing boat parked next to the garage.
