NATIONAL SECURITY: Nuclear energy is safe and provides an important backup if LNG and coal supply is cut off, former US secretary of energy Steven Chu said

The international consensus is drifting toward embracing nuclear energy, and Taiwan’s politicians, regardless of political camp, should also reconsider their stance on the controversial issue, former US secretary of energy Steven Chu （朱棣文） said yesterday at the Forum on the Power for Sustainable Economic Development in Taipei.
Nuclear power is a controversial issue in Taiwan, but other countries are again choosing it as a preferred option, Chu said.
Chu cited a shift in the US, in which the California governor had pledged to shut down two nuclear power plants, but ultimately agreed to extend the licenses for both plants for two decades.
Nuclear power provides energy security, especially when there is no wind and sunlight is weak, he said, adding that “those in the know should give voice to their opinions.”
In terms of nuclear power safety, Chu said to look at the mortality statistics for every kilowatt-hour of electricity generated, stating that the highest mortality rate was held by burning brown coal, followed, in descending order, by coal, diesel, biomass, liquefied natural gas （LNG）, hydroelectricity, wind and, finally, nuclear energy.
Global tech giants such as Meta, Google, Amazon and Microsoft are also evaluating the possibility of using nuclear power, as data centers consume a lot of power, Chu said.
Commenting on net zero goals, Chu said a UN Intergovernmental Panel on Climate Change report concluded that one-quarter of greenhouse gases originated from electricity and heat generation.
The overhead required to develop renewable energy has continued to drop, Chu said, adding that photoelectric power generation overhead has decreased by 80 percent in the past decade, while land-based wind turbines have decreased by 38 percent in the same timeframe.
Forty to 60 percent of electricity would be generated by wind or solar sources by 2040, he said.
However, the power sources are intermittent and would create significant stress on the power grid, he added.
Taiwan’s power grid would need to rely on demand response measures, employ artificial intelligence and establish low-cost energy storage facilities, such as pumped-storage hydroelectricity facilities, to ease the stress on its grid, Chu said.
Taiwan must be aware of the threat of foreign powers damaging LNG pipes to destabilize its power grid, he said.
Even if renewable power comprised 50 percent of Taiwan’s power generation, the remaining half is generated by coal-fired or LNG sources, the latter of which is expensive, while Taiwan has insufficient storage facilities, he said.
At Taiwan’s current storage capacity, the nation would only have 10 days of LNG supply, making it a severe energy security issue if Taiwan was to be cut off, Chu added.
