This photo was taken in Balzac at Walmart's fresh food distribution center. The engineers and construction workers who designed and built this facility - located in the southern portion of the Canadian province of Alberta - used infrared camera to identify energy waste points throughout the center, including at all of the loading docks. Today, this center is home to 71 hydrogen fuels cell powered vehicles, 2 wind turbines (30-kW each), and solar thermal panels - but, the project started with efficiency first. According to Walmart press releases, the facility uses 60% less energy compared to their previous "standard" design.
