Can solar power help Hong Kong grow?

In 2022, Hong Kong's total electricity consumption was approximately 44.7 TWh. The combined physical potential from rooftops and facades exceeds this figure by more than five times, highlighting the critical role solar energy could play in alleviating energy pressure and fostering sustainable growth.

Can Hong Kong achieve a low carbon energy ambition?

With almost all its energy demand met by imported supply, primarily from Mainland China, developing Hong Kong’s indigenous renewable energy from offshore wind offers the potential to meet the city’s low carbon ambition and, at the same time, pursue energy reliance and resilience.

Can PV technology expand the scope of solar energy generation in Hong Kong?

These innovative applications of PV technology present an opportunity to broaden the scope of solar energy generation in Hong Kong. As the city explores ways to diversify its energy sources, the integration of PV technology across various sectors offers a strategic pathway to augment the city's renewable energy matrix.

How can Hong Kong reduce energy consumption?

One way to generate those would be through the introduction of an opt-out system (also known as green default) for all businesses, homeowners and tenants in Hong Kong to offset their own electricity consumption through the purchase of renewable energy certificates (REC).

Does Hong Kong need a solar policy framework?

Bridging the large gap between the estimated building solar PV potential and the actual scale of deployment requires the Hong Kong government to design a supportive regulatory and policy framework for solar energy to overcome existing market barriers. No single policy instrument will serve as a silver bullet.

Can building-integrated solar PV systems help Hong Kong achieve a low-carbon future?

These projections account for 12.68%–16.32% of Hong Kong's total electricity consumption in 2022. This study underlines the substantial role of building-integrated solar PV systems in Hong Kong's transition towards a low-carbon future, offering valuable insights for policymaking and implementation strategies.
