Due to an absence of indigenous energy resources and the second lowest share of total energy consumption from renewable sources in the Asia Pacific region, energy in Hong Kong was derived almost entirely from external and non-renewable sources. Part of power consumed by the city was imported in the form of oil and coal products, and most of the electricity and gas were produced through imported fuel resources. The volume of imported electricity has been on the rise for years, while the volume of imported coal products has reduced from over 0.36 gigajoules in 2014 to around 0.27 gigajoules in 2019.
Looking into the energy consumption by end use, air conditioning required over 48 gigajoules of energy per year, followed by cooking. Among the residential, commercial, industrial and transport sector, transport is the only sector dominated by oil and gas as fuel while others rely more on electricity, which was also mostly derived from fossil resources. Within the transport sector, passenger transport consumed almost double the energy that freight transport did every year, among which land vehicles like goods vehicles, cars and motorcycles took up significantly more energy than other modes of transport.
When it comes to the heated topic of renewable energy, Hong Kong is quite a bit behind the global average with a mere 0.4 percent energy produced from renewable sources. Compared to waste-to-energy which generated over two gigajoules in 2017, other type of renewable energy generation seemed rather insignificant in Hong Kong. In response to the Paris Agreement, effective since 2016, the Hong Kong government has set a target in 2017 to increase the share of renewable energy in the energy fix to three to four percent by 2030, which was still considered too pessimistic to some of the environmental NGOs in the city.
