- Stakeholders are encouraged to consider these energy utilization indexes as one way, but not the only way, of improving their energy performance with respect to the past. Comparisons of indicators between business operations within the same sector should be made with caution. Businesses in the same subgroup may be operating under different economic, environmental and operational constraints, causing different energy performance. The business processes in different business subgroups are inherently varied resulting in different achievable energy performance levels. The energy utilization indexes are derived from studies on a limited size of samples within the population of respective energy-consuming groups. These indicators should not be construed as representative energy consumption levels of the population, nor as territory-wide standards which businesses in the respective energy-consuming groups should comply with.
