At EMSD, we compile data on the use of energy in Hong Kong and publish the publication "Hong Kong Energy End-use Data" which is available free to anyone. The publication covers energy consumption data of the different fuel types and the specific purposes for which they are consumed, e.g. air conditioning, lighting, cooking, etc. The data provides an understanding of the energy consumption patterns and usages, and arouses public interest and concern over the future development of energy in Hong Kong. Additionally, the information provides the Government with the basis to formulate and evaluate energy efficiency policies.
