Solar panels can produce 300 times more toxic waste per unit of electricity generated than nuclear reactors, Michael Shellenberger, president of the US-based group Environmental Progress, told a forum in Taipei yesterday, while presenting an open letter to President Tsai Ing-wen (蔡英文).
The forum was held by Climate Vanguards and the Chung Hwa Nuclear Society at National Taiwan University.
There used to be a tug-of-war between pro and anti-nuclear groups, but the anti-nuclear camp has gained favor ever since the 2011 Fukushima Dai-ichi disaster in Japan, former Environmental Protection Administration minister Wei Kuo-yen (魏國彥) said in the first panel discussion with Shellenberger.
Debates about energy policy have become ideological rather than scientific, Wei said, adding that nuclear power is the best option for the nation’s transformation from a “brown” economy bolstered by fossil fuels to a “green” economy.
Shellenberger questioned the legitimacy of the claim of causation between the disaster and the nation’s decision to phase out nuclear power.
Even though thousands of people died in the earthquake, no deaths were directly caused by radiation leaks, Shellenberger said.
Presenting an open letter to Tsai, Shellenberger said that the nation’s phase-out of nuclear power is based on misinformation.
Replacing nuclear with fossil fuels can threaten public health, given that Taiwanese are exposed to unsafe levels of air pollution, he said.
Natural gas is also not a good substitute for nuclear sources, considering the heavy casualties of the gas explosions in Kaohsiung in 2014, he said.
As for development of renewables, the nation would need to build 617 solar farms as large as its biggest proposed farm at a cost of US$71 billion just to replace its nuclear reactors, he said, adding that few people consider disposal of solar panels.
He advised Tsai’s administration to hold a national referendum on the future of nuclear energy, just as South Korean President Moon Jae-in held a “citizens’ jury,” which last week voted to resume construction of two nuclear plants.
Following a similar vein, physicist and pro-nuclear activist Huang Shih-hsiu (黃士修) said that the ruling Democratic Progressive Party should tell people the real cost of phasing out nuclear power by revealing the facts.
While the nation hopes to generate 50 percent of electricity from natural gas, 20 percent from renewable sources and 30 percent from coal by 2025, gas-fired power and renewable production are costly and risky, he said.
Nuclear power and renewables should coexist and supplement each other, or the nation will face more power outages and higher electricity prices, he said.
Taiwanese should have fully understood the merits and defects of different energy sources before deciding to phase out nuclear energy, Huang added.
DEEPER REVIEW: After receiving 19 hospital reports of suspected food poisoning, the Taipei Department of Health applied for an epidemiological investigation A buffet restaurant in Taipei’s Xinyi District (信義) is to be fined NT$3 million (US$91,233) after it remained opened despite an order to suspend operations following reports that 32 people had been treated for suspected food poisoning, the Taipei Department of Health said yesterday. The health department said it on Tuesday received reports from hospitals of people who had suspected food poisoning symptoms, including nausea, vomiting, stomach pain and diarrhea, after they ate at an INPARADISE (饗饗) branch in Breeze Xinyi on Sunday and Monday. As more than six people who ate at the restaurant sought medical treatment, the department ordered the
A strong continental cold air mass and abundant moisture bringing snow to mountains 3,000m and higher over the past few days are a reminder that more than 60 years ago Taiwan had an outdoor ski resort that gradually disappeared in part due to climate change. On Oct. 24, 2021, the National Development Council posted a series of photographs on Facebook recounting the days when Taiwan had a ski resort on Hehuanshan (合歡山) in Nantou County. More than 60 years ago, when developing a branch of the Central Cross-Island Highway, the government discovered that Hehuanshan, with an elevation of more than 3,100m,
Taiwan’s population last year shrank further and births continued to decline to a yearly low, the Ministry of the Interior announced today. The ministry published the 2024 population demographics statistics, highlighting record lows in births and bringing attention to Taiwan’s aging population. The nation’s population last year stood at 23,400,220, a decrease of 20,222 individuals compared to 2023. Last year, there were 134,856 births, representing a crude birth rate of 5.76 per 1,000 people, a slight decline from 2023’s 135,571 births and 5.81 crude birth rate. This decrease of 715 births resulted in a new record low per the ministry’s data. Since 2016, which saw
SECURITY: To protect the nation’s Internet cables, the navy should use buoys marking waters within 50m of them as a restricted zone, a former navy squadron commander said A Chinese cargo ship repeatedly intruded into Taiwan’s contiguous and sovereign waters for three months before allegedly damaging an undersea Internet cable off Kaohsiung, a Liberty Times (sister paper of the Taipei Times) investigation revealed. Using publicly available information, the Liberty Times was able to reconstruct the Shunxing-39’s movements near Taiwan since Double Ten National Day last year. Taiwanese officials did not respond to the freighter’s intrusions until Friday last week, when the ship, registered in Cameroon and Tanzania, turned off its automatic identification system shortly before damage was inflicted to a key cable linking Taiwan to the rest of
