A fan controls the temperature of a hangar at the Niagara Falls Air Reserve Station, October 20, 2014. The fan keeps the hangar at a mild temperature year round, saving on the cost of heating and cooling. October is Energy Action Month throughout the federal government and is about creating an Energy Aware Culture, where Airmen are getting personally involved and finding innovative ways to help the Air Force meet our energy goals.
