NOTE:

  1. Definition of each subgroup is shown in the glossary
  2. 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 within the same sector should be made with caution. The energy performance are affected by a number of factors such as housekeeping habit, household size and much dependent on the living standard pursued by the stakeholder. 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 stakeholders in the respective energy-consuming groups should comply with.
