Letters | Nuclear energy must be a big part of Hong Kong’s carbon reduction plan

  • Readers discuss how Hong Kong can reduce carbon emissions, the sustainability of China’s zero-Covid policy, the importance of Chinese-Australians’ vote in the recent election, and the biggest threat to the US

I refer to the letter “Four lessons that Sweden can teach Hong Kong on reducing carbon emissions” (June 1). To the “four lessons”, let me offer four responses.

First, our government would love more government-business cooperation. It is an open invitation to yet more “advisory committees”, “consultative groups”, “dialogue” and “ongoing discussions”, which are always “win-win”. These may achieve results in Sweden, but here in Hong Kong they’re just a way to kick that proverbial can down the road.

Second, on the suggestion to “revisit the energy mix”, your correspondents fail to mention that in Sweden nuclear energy comprises about 30 per cent of the energy mix as is the case in Hong Kong. Wind and solar are all very well, but cannot dominate Hong Kong’s electricity supply because we simply don’t have the space.

I have just installed rooftop solar, but we have a house. More widespread residential rooftop solar – which we should encourage – cannot be a solution to carbon dioxide emissions in Hong Kong as we are one of the world’s most vertical cities. Commercial solar needs many times more land to produce the same amount of electricity as a modern nuclear reactor. Where will we get that land when we have intense competition from housing? From the remains of the Fanling golf course?

Surely we ought to be looking at replicating the magnificent Daya Bay nuclear power station close by on the mainland or consider small modular reactors right here in Hong Kong. If we think we have land for solar and wind, we most assuredly have land for nuclear.
