As part of the $15 million expansion and renovation, the library now draws its energy from two renewable energy resources. The building, expanded from 20,000 square feet to 39,000 square feet, has a photovoltaic solar energy array on the newly added second story, as well as geothermal energy for heating and cooling. The ability to install a solar array at E.C. Scranton was made possible by adding the geothermal system to the renovation and expansion project, according to Curtis. In order to make the geothermal heating and cooling system work, construction crews needed to drill 25 wells beneath what ultimately has become the library’s expanded parking lot, according to Curtis. The renovation and expansion project was started in October 2018 and completed last July. The library is a nonprofit entity that gets some money from the town, Curtis said. To pay for the costs associated with the project, the town provided $9 million of the total cost and $2 million came from the state.
