The Naval Facilities Public Works Department on GTMO is working every day to help transform the way we use energy. A change currently being implemented is the construction of new solar panel arrays near the Naval Exchange which will lighten the load on the current fossil fuel generators. The panels, expected to be complete by the end of December, will provide almost enough energy during sunlight hours – 700 kilowatts of energy per day, which roughly equates to 250,000 kilowatts a year – to make the NEX self-sufficient.
