What You'll Learn
Hong Kong's electricity sources
Hong Kong's electricity is generated through a mix of fuel sources, including natural gas, coal, nuclear power, and renewable energy. In 2020, natural gas dominated the fuel mix, accounting for around 48% of electricity generation. This is a significant shift from 2012 when coal was the primary source of electricity generation, contributing 53%, while natural gas accounted for 22%.
The Hong Kong government has implemented measures to reduce reliance on coal and transition to cleaner energy sources. Under the Climate Action Plan 2030+, the city aims to increase the use of natural gas to more than 50% by 2030. This move towards natural gas has helped reduce carbon emissions, as it produces fewer emissions per electricity unit compared to coal. Additionally, the government established the Energy Advisory Committee and the Energy Efficiency Office (EEO) to promote energy efficiency and conservation. The EEO issues Building Energy Codes (BEC) to regulate energy consumption in construction projects, which has effectively reduced energy usage in buildings.
Nuclear energy also plays a significant role in Hong Kong's electricity mix. In 2012, 23% of the city's electricity was imported as nuclear energy from the mainland. The CLP Group, a local power company, has contractual agreements with the Daya Bay Nuclear Power Plant in mainland China, importing 70% of its electricity output. The use of nuclear energy has helped reduce Hong Kong's carbon dioxide emissions by more than 7.5 million tonnes per year.
While renewable energy sources currently play a minor role in Hong Kong's electricity generation, there are ongoing efforts to increase their contribution. The city's Climate Action Plan 2050 outlines key milestones toward carbon neutrality, including a focus on renewable energy. Due to its subtropical location, Hong Kong has the potential to generate significant solar energy. The government is investing in renewable energy projects, such as a facility in Tuen Mun that treats waste and sewage to produce energy. However, the city's small geographical size poses challenges in expanding its green energy capacity.
Overall, Hong Kong's electricity sources have diversified and evolved over time, with a growing emphasis on cleaner and more sustainable energy options. The city continues to strive for a low-carbon economy by transitioning away from coal and exploring renewable alternatives.

Transitioning to low-carbon sources
Hong Kong's electricity sector is transitioning to low-carbon sources as part of its Climate Action Plan 2030+. The city aims to reduce its reliance on coal and increase the use of natural gas and non-fossil fuel sources. Natural gas is one of the cleanest forms of fossil fuels, producing the least amount of carbon emissions per electricity unit. The city plans to increase its use of natural gas to more than 50% by 2030. This transition is crucial, given that buildings consume 90% of the city's electricity and are responsible for 60% of carbon emissions, with air conditioning as the largest single consumption category.
To further reduce carbon emissions, Hong Kong is also investing in renewable energy projects, despite the challenges posed by its small geographical size. The city's subtropical location, however, provides an advantage for generating a significant amount of solar energy. The government has implemented various initiatives, such as the trial scheme by the Environmental Protection Department and the Drainage Services Department, which treats food waste and sewage to produce energy. Additionally, Hong Kong imports electricity from the Daya Bay Nuclear Power Station, which provides non-carbon emitting energy.
The CLP Group, a local power company, plays a significant role in Hong Kong's transition to low-carbon sources. CLP transmits electricity in Kowloon and the New Territories, and its transmission networks consist mainly of overhead lines. CLP also owns the Black Point Power Station, a gas-fired power station, and the Castle Peak Power Station, which primarily uses coal but can burn gas as a backup fuel.
To support the government's environmental goals, CLP has committed to reducing the environmental impact of Hong Kong's energy consumption. They maintain a diversified fuel mix and utilise advanced emissions controls to meet environmental standards. Additionally, CLP has expressed its intention to buy more nuclear power from the Daya Bay Plant, increasing its share of the plant's output capacity.
Hong Kong's Climate Action Plan 2050 outlines key milestones toward carbon neutrality, including halving carbon emissions before 2023 compared to the 2005 level and achieving "net-zero electricity generation." The city's progress in transitioning to low-carbon sources is supported by various initiatives, investments, and infrastructure developments, demonstrating its commitment to a more sustainable future.

Energy imports from mainland China
Hong Kong's small geographical size and limited resources make it difficult to produce renewable energy. As a result, Hong Kong imports 23% of its electricity from Mainland China, with over 12% of that power coming from renewable sources.
CLP's electrical grid is interconnected with the China Southern Power Grid of Mainland China. CLP imports 23% of its total electricity from generating facilities with equity in mainland China. This includes a contractual agreement for 70% of the electricity output from the Daya Bay Nuclear Power Plant, and some peaking power/pumping load from the Guangzhou Pumped Storage Power Station in Conghua.
Hong Kong's electricity consumption increased from 150,705 TJ in 2010 to 159,124 TJ in 2020, a 5.6% increase. In 2021, 178,301 TJ (49.528 TWh) of electricity was consumed, accounting for 51.8% of total energy consumption in Hong Kong.
In 2020, natural gas dominated the fuel mix in Hong Kong, at around 48%, followed by nuclear energy and renewables at 28%, and coal at 24%. Hong Kong's Climate Action Plan 2030+ aims to increase the use of natural gas to more than 50% by 2030, while reducing reliance on coal.
The city has various concurrent projects and efficiency codes dedicated to renewable energy. The government of Hong Kong invests in and develops renewable energy projects, in accordance with its Climate Action Plan 2050.

Hong Kong's Climate Action Plan 2030+
One of the key goals of the plan is to reduce Hong Kong's reliance on coal for electricity generation. In 2012, coal accounted for 53% of the city's electricity generation, with natural gas and nuclear energy also playing significant roles. To reduce coal usage, the plan aims to increase the share of natural gas in the fuel mix to more than 50% by 2030. This is expected to significantly reduce carbon emissions, as natural gas produces fewer emissions per unit of electricity generated compared to coal. Additionally, the plan encourages the development and utilisation of renewable energy sources, such as solar power, to further reduce the reliance on fossil fuels.
The Climate Action Plan also addresses the transport sector, aiming to reduce emissions from vehicles and promote sustainable mobility. Initiatives include extending rail services, improving public transport services, fostering a bicycle-friendly environment, and introducing new automotive technology. Bus route rationalisation is also mentioned, aiming to enhance network efficiency, reduce traffic congestion, and lower roadside air pollution.
To support the transition to cleaner energy sources, Hong Kong is exploring the feasibility of using an offshore liquefied natural gas (LNG) terminal for regasification. Additionally, the plan recognises the importance of reducing overall energy consumption and promoting energy efficiency. This includes initiatives such as "energy saving and green buildings", aiming to reduce energy demand and lower carbon emissions associated with the built environment.
