Energy is all around us, simply as heat and light, and in more complex mechanical, electrical, chemical and nuclear forms. Find an overview of how you can be energy efficient.

In recognition of the need to improve energy efficiency in Hong Kong, the Government has introduced a voluntary energy efficiency labelling scheme. Learn more about the scheme, the types of appliances and equipment it covers, and where you can check if a product is registered.

To further facilitate the public in choosing energy efficient appliances and raise public awareness on energy saving, the Government has introduced a mandatory Energy Efficiency Labelling Scheme (EELS) through the Energy Efficiency (Labelling of Products) Ordinance.

Another energy efficiency initiative is the Energy Efficiency Registration Scheme for Buildings. This voluntary scheme encourage building owners achieving better energy performance beyond the statutory requirements.

To improve building energy efficiency, the Government formulated the Buildings Energy Efficiency Ordinance. Under the Ordinance, certain prescribed types of buildings have to comply with Building Energy Code (BEC) and/or Energy Audit Code (EAC).

The use of fresh water cooling towers can significantly reduce electricity consumption by air-conditioning. With this in mind, the Government has launched a voluntary scheme on fresh water cooling towers for non-domestic buildings in designated areas.

To address the problems of light nuisance and energy wastage caused by external lighting, the Environment Bureau launched the first-ever Charter on External Lighting.  Owners of and persons responsible for external lighting installations are invited to switch off lighting installations with decorative, promotional or advertising purposes which affect the outdoor environment during preset times.

The electricity market in Hong Kong has all along been regulated through the Scheme of Control Agreements (SCAs) signed between the Government and the two power companies. The SCAs set out the obligations of the companies, the returns for shareholders and the arrangements by which the Government monitors the companies' electricity-related financial affairs.
