As we have solar panels on our rooftop here in Discovery Bay, I’d like to comment on the letter, “ Solar power needs a bigger push ” (January 19). First, CLP pays us for the solar electricity we feed into its grid under the “feed-in-tariff”scheme , currently over five times what we pay CLP for the electricity we consume. So there is a subsidy involved, which must remain to make it viable for consumers to install photovoltaic panels. Second, Hong Kong is a vertical city, whereas Australia is a largely horizontal one. We have many more high-rise buildings than Australia. That means fewer rooftops per capita on which to put solar panels. Therefore solar power at scale would have to be on our “brownfield” sites . These are nowhere near enough to lead us to “net zero”. The fundamental problem with solar energy – apart from not being able to produce energy at night – is that it is “energy-dilute”. Nuclear power, by contrast, is very “energy-dense”. Thus California’s Ivanpah solar farm is spread across 3,500 acres and has a gross capacity of 392 megawatts, while the state’s Diablo Canyon nuclear power plant takes up 750 acres and has a capacity of 2,256MW . Hong Kong gets 25 per cent of its electricity from the Daya Bay nuclear power station. Imagine the amount of land needed to generate the equivalent amount of electricity from solar power. So why do we so rarely discuss nuclear power for Hong Kong? There are four nuclear stations in Guangdong from which we could take power . The objections to nuclear energy are outdated. Nuclear power is among the cleanest, safest and cheapest forms of power. Yet here we are still frittering around with solar, an unlikely “net zero” saviour. Why aren’t green groups in Hong Kong pressing for the increased use of nuclear power? They worry about a “climate emergency” but deny nuclear power. I call on all of us concerned about climate change in Hong Kong to learn the science and to call for acceptance of more nuclear power in Hong Kong, for the sake of our climate and our children. Peter Forsythe, Discovery Bay Good fences would make humans, boars good neighbours I am writing in response to the report , “More Hong Kong residents injured by wild boars last year despite authorities culling hundreds of the animals” (January 8). In recent years, many Hong Kong residents have been injured by wild boars. This is not surprising when the city’s development has caused a shrinking of the habitats of our wildlife. However, the situation can be ameliorated. First, people should stop feeding wild boars as this causes the animals to depend on humans as a source of food in the long run. Second, the government should add more fences to prevent people from stumbling into areas that wild boars frequent in the countryside. Such fences would also prevent people from feeding the boars.
