Promoting the Use of Renewable Energy in Hong Kong

The Government as well as some other non-government organizations have been promoting the use of renewable energy in Hong Kong through conducting studies and publicizing results of the studies, public education, demonstration projects, etc. Among these, this website is one of the promotional initiatives of the Government.

In year 2000, the Energy Efficiency Office commissioned a two-stage consultancy study to investigate the viability of using renewable energy resources such as solar energy, wind energy, wave energy, landfill gas, etc. in Hong Kong. Stage 1 of the study, completed in December 2002, evaluated the potentials of various forms of renewable energy for wide-scale local use, and their related legal, institutional and promotional issues. It also made recommendations for formulating an implementation strategy. Stage 2 of the study involved the installation of different types of photovoltaic panels in Wanchai Tower so as to collect technical data to assess their performance under local weather and environmental conditions. The twelve-month performance monitoring work was completed in March 2004.

The reports of the whole study can be downloaded here:

In 2005, the Electrical and Mechanical Services Department put into service a 350kW PV installation in Hong Kong and a 1kW small wind turbine on the roof of the EMSD Headquarters building. The installation becomes part of the EMSD Education Path at the EMSD Headquarters, which is open for visit by interested organizations.

The first commercial-scale wind turbine in Hong Kong was built by the Hongkong Electric Company (HEC) limited as a demonstration project on Lamma Island. The wind power station, which consists of a single wind turbine and a cluster of exhibition panels, was inaugurated in February 2006. The wind turbine is an 800 kW a three-blade machine with a rotor diameter of 50 meters. The hub height of the wind turbine is 46 metres. The wind turbine generates electricity when the wind speed falls in the range of 3 m/s to 25 m/s.

The other power company in Hong Kong, CLP Power (Hong Kong) Limited, is planning to construct a commercial-scale wind turbine on an island in Hong Kong, also to serve as a demonstration project.

Besides, both power companies are also exploring the feasibility of constructing off-shore windfarms in Hong Kong waters (see Offshore Wind Farm - Technology Outline section).
