Electricity consumption forms more than half of Hong Kong’s annual energy end-use
More than half (54%) of Hong Kong’s total annual energy end-use is in the form of electricity consumption. The rest is used in the form of oil and coal products, town gas and liquefi ed petroleum gas(LPG), and to a very small extent, biodiesel.

In 2014, Hong Kong consumed 289,160 TJ of energy. Figure on the left shows the distribution of energy end-uses by fuel types. Hong Kong’s energy consumption comprises three fuel types – the largest fuel type use is electricity, oil and coal products, and town gas and LPG. In recent years, a very small amount of biodiesel is used.
Since 2004, the consumption of electricity, town gas and LPG had increased at an average rate of 1.2% per annum, while the consumption of oil and coal products fell at an average of 1.6% per annum. Compared with 2004, the share of electricity had increased by 4.8% and town gas and LPG by 1.5%, while oil and coal products dropped 6.2%.
Air-conditioning -- the largest electricity end-use
In Hong Kong, the main energy used in buildings is electricity and our buildings consume 90% of the city’s electricity. Certain types of electricity use in buildings are particularly signifi cant. Not surprisingly, air-conditioning is the largest electricity end-use in Hong Kong, followed by lighting, office equipment and cooking.
Hong Kong consumed 158,147 TJ of electricity in 2014. Air-conditioning accounts for 31.7%, lighting 12.9%, and cooking 8% respectively of the total electricity end-uses.
Consumption By Sectors
T he Figure in "Electricity Consumption" shows both the commercial(161%) and residential sectors (116%) registered large increases in electricity consumption. The percentage increase in electricity demand is higher than the increase in total energy demand in the corresponding sector, which means there has been a gradual shift towards using more electricity versus other fuels.
Whether the overall electricity consumption trend will continue in the future will depend on not only government policy but a variety of factors, such as changes in demographics and household size and so on.
All Energy Consumption* By Sectors
*: All Energy Consumption equal to the sum of the three types of consumption.
The left table shows that energy consumption increased by 26% (average 1.1% per annum) in all sectors except the industrial sector.As Hong Kong transited towards a service economy, the economy became less energy intensive while the manufacturing industries relocated to the Mainland, starting gradually in the 1980s and accelerating in the 1990s.
