We are going around the city to demonstrate the potential of renewable energy, and give you a taste of solar! (© WWF-Hong Kong)
Given our geographical position and our location in the subtropics, Hong Kong is exposed to a lot of solar radiation. WWF’s “Solarising Communities” project launched in 2016 installed on-grid solar PV systems on the rooftops of three stilt houses in Tai O, demonstrating the city’s potential to develop solar energy. The project is now being extended with a 100 per cent solar-powered mobile café that is visiting different districts around the city, offering the public a taste of solar energy.
100% Solar Mobile Café
The bike is rolling through the cities until March 2018. Between each deployment, the bike will be moving outdoor to generate solar and partially charge the battery, ensuring it is 100 per cent powered by solar.
How much will you pay for electricity? It is up to you!
The new Scheme of Control Agreement signed by the government and two power companies has introduced a feed-in tariff policy, i.e. the two power companies will rebate electricity generated by renewable sources. The rebate rate has yet to be announced. WWF believes that an initial rate should be set at an attractive level to provide a payback period within 8-10 years, promoting community investment in sustainable and clean energy alternatives.
Feed-in Tariff should be set at HK$4 per unit
Assuming that your home is available and suitable for installing a solar PV system, how will the feed-in-tariff rebate rate affect the payback period of the system?
Increase local renewable electricity share to 10 per cent
Currently, Hong Kong’s electricity fuel mix contains about 70 per cent of energy generated by fossil fuels, while only 0.1 per cent is generated by renewable energy. The government should set a long-term target to increase investment in renewable energy to a 10 per cent in the electricity fuel mix by 2030 to facilitate a comprehensive energy turnaround.
WWF is committed to promote the development of renewable energy and we urge the government to:
- set the introductory feed-in-tariff rate at HKD$4/kWh to rebate all electricity generated by small-scale domestic solar systems
- increase the use of the local renewable electricity share to 10 per cent by 2030.

Invest in market of distributed solar generation
Individuals and corporates can examine the potential of installing renewable energy systems on rooftops, terraces, and open areas to generate our own power!
Ideal rooftop solar system:
- rooftops that are facing south or south-oriented with minimal shade from nearby buildings or trees
- an area of around 25m2 is required for a 2.5kW system, supplying half of an average household’s annual electricity
Support local renewable energy markets by applying for the renewable energy certificates
WWF has launched the Hong Kong’s first-ever Renewable Energy Certificate (REC) scheme to allow companies to offset their carbon footprint and take part in the development of local renewable energy by purchasing energy that is guaranteed to be 100 per cent solar generated by the systems in Tai O. In the future, corporates can continuously support the local renewable energy markets by applying for the RECs launched by the two power companies.
