The document discusses 7 habits of highly effective energy managers. It notes that fans and pumps are often oversized leading to inefficiency. Compressed air is very expensive to use compared to electric motors. Lighting systems should use sensors and controls to save energy by turning off unoccupied areas. Low hanging fruit like air leaks or poor maintenance always seem to return and require continual management. Production needs sometimes conflict with energy efficiency efforts but energy management provides opportunities. Regular sub-metering and measuring energy use allows managers to focus on significant energy uses and track performance metrics like energy intensity per unit of production.
