The Hong Kong government should set a target of improving energy efficiency by 1 to 2 percent a year while progressively increasing the use of renewable energy sources, such as solar and wind power, the World Wide Fund for Nature’s (WWF) Hong Kong branch proposed in its Hong Kong Energy Vision 2050 report.
As the government plans to phase out nuclear power and coal in the next 20 to 25 years and rely almost solely on natural gas to meet the city’s energy needs, carbon emission is projected to reach 26.63 million tons in 2050, up 16 percent from the 1990 level, the environmental protection group said.
The projection is based on the assumption that annual electricity consumption and maximum electricity demand will continue to grow by 1 to 2 percent.
Sarah Keung, senior campaign officer of WWF Hong Kong’s climate project, said although natural gas is cleaner than coal, it is still a fossil fuel which has carbon emission. She believes the right direction is to promote the use of renewable energies.
The city should increase the proportion of renewable energies in the fuel mix to 5 percent by 2030 from less than 1 percent now, and further to 30 percent by 2050, the report said.
The group also suggests that renewable energy from mainland China could account for 55 percent in the fuel mix by 2050, with natural gas contributing 15 percent.
As for domestic renewable energy sources, WWF Hong Kong recommends solar and wind power.
