Taiwan is turning off its last nuclear reactor today, fueling concerns over the nation’s reliance on imported energy and vulnerability to a Chinese blockade.
Taiwan, which targets net zero emissions by 2050, depends almost entirely on imported fossil fuel to power its homes, factories and critical semiconductor industry.
President William Lai’s (賴清德) Democratic Progressive Party has long vowed to phase out nuclear power, while the Chinese Nationalist Party (KMT) says continued supply from the technology is needed for energy security.

The Ma-anshan Nuclear Power Plant in Pingtung County is being closed as China intensifies military activity around Taiwan.
During large-scale military drills around Taiwan last month, China simulated strikes on key ports and energy sites, as well as blockading the nation.
Ma-anshan has operated for 40 years in a region popular with tourists, and which is now dotted with wind turbines and solar panels.
More renewable energy infrastructure is planned at the site, where state-owned Taiwan Power Co plans to build a solar power station capable of supplying an estimated 15,000 households annually.
However, while nuclear power only accounted for 4.2 percent of Taiwan’s supply last year, some fear that Ma-anshan’s closure risks an energy crunch.
“Taiwan is such a small place and currently there’s no other better and more efficient natural energy source that can replace nuclear power,” said Ricky Hsiao, 41, who runs a nearby guesthouse.
“The reality is that TSMC and other big companies need a lot of electricity. They would leave Taiwan if it’s not stable,” he said, referring to chipmaking giant Taiwan Semiconductor Manufacturing Co.
However, mother-of-two Carey Chen fears an accident like the 2011 Fukushima Dai-ichi nuclear power plant meltdown in Japan, which, like Taiwan, is prone to earthquakes.
“If we can find other stable power sources, I support a nuclear-free homeland for everyone’s safety,” said Chen, 40.
At its peak in the 1980s, nuclear power made up more than 50 percent of Taiwan’s energy generation, with three plants operating six reactors across the nation.
Concerns after the Fukushima disaster saw a new plant mothballed in 2014 before it was even finished. Two other plants stopped operating between 2018 and 2023 after their operating permits expired.
Most of Taiwan’s power is fossil fuel-based, with liquefied natural gas (LNG) accounting for 42.4 percent and coal 39.3 percent last year.
Renewable energy made up 11.6 percent, well short of the government’s target for this year of 20 percent.
Solar has faced opposition from communities worried about panels occupying valuable land, while rules requiring locally made parts in wind turbines have slowed their deployment.
Lai insists that Taiwan’s energy supply would be stable even as artificial intelligence technology boosts demand, with new units in existing LNG and coal-fired plants replacing Ma-anshan’s output.
The KMT and the Taiwan People’s Party, which together hold a majority in the Legislative Yuan, on Tuesday amended a law enabling nuclear plants to extend their operating life by up to 20 years.
“Nuclear power is not the most perfect way to generate electricity, but it is an option that should not be eliminated when we are developing technology, defense and strengthening national security,” KMT Legislator Ko Ju-chun (葛如鈞) said.
Taiwan’s reliance on imported fossil fuels is of particular concern given the risk of a Chinese blockade.
The nation has enough LNG and coal reserves to last just 11 and 30 days respectively, government data showed.
Taiwan’s centralized electricity grid also leaves swaths of the nation at risk of major power outages in case of a single fault.
Without nuclear power, “our energy security cannot be guaranteed and national security will be affected,” said Yeh Tsung-kuang (葉宗洸), an energy expert at National Tsing Hua University.
Environmentalists argue that renewables are the best way to bolster Taiwan’s energy resilience.
“If every community has solar panels on its roofs, the community can be [more] self-sufficient,” said Tsui Shu-hsin (崔愫欣), secretary-general of Green Citizens’ Action Alliance.
However, others say that Taiwan’s break-up with nuclear power generation is at odds with global and regional trends.
Even Japan aims for nuclear to account for 20 to 22 percent of its electricity generation by 2030, up from well under 10 percent now.
And nuclear power became South Korea’s largest source of electricity last year, accounting for 31.7 percent of its total power generation and reaching its highest level in 18 years, South Korean government data showed.
Hengchun Township (恆春) Mayor Yu Shih-ching (尤史經), who is head of the region where the Ma-anshan plant is, said that the facility had brought jobs and boosted the local economy.
“Our view is that nuclear power is necessary,” Yu said, calling it “an important driving force for the national economy” and a “great help to local areas.”
Lai said that he would not rule out a return to nuclear power one day.
“Whether or not we will use nuclear power in the future depends on three foundations: nuclear safety, a solution to nuclear waste and successful social dialogue,” he said.
The first two F-16V Bock 70 jets purchased from the US are expected to arrive in Taiwan around Double Ten National Day, which is on Oct. 10, a military source said yesterday. Of the 66 F-16V Block 70 jets purchased from the US, the first completed production in March, the source said, adding that since then three jets have been produced per month. Although there were reports of engine defects, the issue has been resolved, they said. After the jets arrive in Taiwan, they must first pass testing by the air force before they would officially become Taiwan’s property, they said. The air force
GLOBAL: Although Matsu has limited capacity for large numbers of domestic tourists, it would be a great high-end destination for international travelers, an official said Lienchiang County’s (Matsu) unique landscape and Cold War history give it great potential to be marketed as a destination for international travelers, Tourism Administration Director General Chen Yu-hsiu (陳玉秀) said at the weekend. Tourism officials traveled to the outlying island for the Matsu Biennial, an art festival that started on Friday to celebrate Matsu’s culture, history and landscape. Travelers to Matsu, which lies about 190km northwest of Taipei, must fly or take the state-run New Taima passenger ship. However, flights are often canceled during fog season from April to June. Chen spoke about her vision to promote Matsu as a tourist attraction in
The Chinese People’s Liberation Army Navy’s (PLAN) third aircraft carrier, the Fujian, would pose a steep challenge to Taiwan’s ability to defend itself against a full-scale invasion, a defense expert said yesterday. Institute of National Defense and Security Research analyst Chieh Chung (揭仲) made the comment hours after the PLAN confirmed the carrier recently passed through the Taiwan Strait to conduct “scientific research tests and training missions” in the South China Sea. China has two carriers in operation — the Liaoning and the Shandong — with the Fujian undergoing sea trials. Although the PLAN needs time to train the Fujian’s air wing and
PAWSITIVE IMPACT: A shop owner said that while he adopted cats to take care of rodents, they have also attracted younger visitors who also buy his dried goods In Taipei’s Dadaocheng (大稻埕), cats lounging in shops along Dihua Street do more than nap amid the scent of dried seafood. Many have become beloved fixtures who double as photography models, attracting visitors and helping boost sales in one of the capital’s most historic quarters. A recent photo contest featuring more than a dozen shop cats drew more than 2,200 submissions, turning everyday cat-spotting into a friendly competition that attracted amateur and professional photographers. “It’s rare to see cats standing, so when it suddenly did, it felt like a lucky cat,” said Sabrina Hsu (徐淳蔚), who won the NT$10,000 top prize in
