As the UN steps up calls to make the switch to renewable energy to fight the global climate emergency, Portugal is among the first EU countries to abandon coal.
It is to share the lessons it has learned so far at next month’s COP27 UN climate summit in Egypt.
It has been nearly a year since smoke has trailed up from the cooling towers of the coal plant in Pego, 120km northeast of the capital, Lisbon.
The lights are off at the station and the dust gathering on the steel structure attests to the fact that the last coal plant in Portugal shut down in November last year after 30 years in service.
The authorities in Lisbon shut down the fossil-fuel plant eight years sooner than planned — and just months after the Sines coal plant, about 90km south of Lisbon, closed at the start of last year.
Portugal is one of a handful of EU member states — along with Belgium and Sweden — to have renounced coal as an energy source.
The energy crisis triggered by Russia’s invasion of Ukraine prompted Austria to reverse a previous decision to close coal-fired plants.
However, Portugal “remains convinced that it will not be necessary to renege on this decision,” Portuguese Minister of Environment and Climate Action Duarte Cordeiro said last month.
“Portugal is an example in Europe,” said Pedro Nunes, an expert in renewable energy at the University of Lisbon and policy officer with the environmental group Zero.
The two coal plants recently closed accounted for nearly 20 percent of Portugal’s greenhouse gases, he said.
To replace coal’s contribution to electricity production, the government hopes to continue developing its green energy to provide 80 percent of its energy by 2026, up from 40 percent in 2017.
If the share of renewables in electrical output hit nearly 60 percent last year, the figure dropped back to 40 percent this year owing to a historic drought, which slashed hydroelectric power.
The UN’s World Meteorological Organization on Tuesday last week called for the world to double the supply of electricity from renewables by 2030 to prevent climate change from undermining global energy security.
Electricity has not only been a major source of carbon emissions driving climate change, but it is also vulnerable to the effects of a warming planet, the organization said.
Portugal is aiming to increase its wind power and solar capacity — it ranks eighth and 13th respectively in Europe.
However, it remains heavily dependent on fossil fuels, which accounted for 71 percent of its energy mix in 2020, according to Eurostat.
In this transition phase, the strategy “initially passes via electricity produced by gas plants, which are one-third less polluting than coal,” Nunes said.
Portugal has used natural gas-fired combined cycle power plants like the one running since 2011 on the Pego site, next to the decommissioned coal plant. It is scheduled to run until 2035.
“It’s not by chance” that Portugal has been among the first in Europe to abandon coal, said Pedro Almeida Fernandes, tasked with renewable energies for the Portuguese subsidiary of Spain’s Endesa.
The country has been preparing for its energy transition “for a long time,” he said.
Endesa won the contract to reconvert by 2025 the Pego coal plant into a complex combining solar power, wind energy and green hydrogen. This is, after all, a place that enjoys 300 days of sunshine per year.
With that kind of resource, Portugal aims to increase solar power production by 50 percent to 3 gigawatts this year, a government estimate showed.
SOUTH CHINA SEA SPAT: The image bolsters a Philippine Coast Guard assertion that Chinese inflatable boats deployed floating barriers at the shoal’s entrance last week Satellite images of the hotly disputed Scarborough Shoal (Huangyan Island, 黃岩島) in the South China Sea show a new floating barrier across its entrance, near where Philippine ships and Chinese coast guard vessels have had frequent run-ins. One of the images taken by Maxar Technologies on Thursday last week and viewed by Reuters showed the barrier blocking the mouth of the shoal, where the Chinese coast guard last week claimed to have driven off a Philippine vessel “illegally intruding” into Beijing’s waters. Manila, which last week deployed a Philippine Bureau of Fisheries and Aquatic Resources (BFAR) vessel to patrol the shoal and
Satoshi Kirishima spent almost half a century evading arrest, until mortality intervened. As deathbed confessions go, his was astonishing: Having lived a double life as a construction worker, the 70-year-old was admitted last month to a hospital near Tokyo where he told staff he was one of Japan’s most-wanted fugitives. In a more recent image provided to Japanese media by an acquaintance, it is just possible to discern a resemblance with the black-and-white photograph that has adorned Japanese police boxes for decades showing a bespectacled, smiling university student with shoulder-length hair. While he shared details of his family and his organization that only
CHINA LINKS: A report said that there were concerns about the loyalty of Qiu Xiangguo and Cheng Keding due to their direct contact with entities linked to China Two scientists at Canada’s top infectious disease laboratory lost their jobs after reviews found that they failed to protect sensitive assets and information, and failed to acknowledge collaborations with China, newly released records showed. The scientists, Qiu Xiangguo (邱香果) and her husband, Cheng Keding (成克定), were stripped of their security clearances in 2019 at Canada’s National Microbiology Laboratory over questions about their loyalty to Canada, and the potential for coercion or exploitation by a foreign entity, the documents say. More than 600 pages were made public on Wednesday following a special all-party review of the records. The records show that the Canadian Security
‘RUSSIA CANNOT WIN’: The French president declined to say which nations were considering sending troops, saying he prefers to maintain some ‘strategic ambiguity’ French President Emmanuel Macron on Monday said that sending Western troops on the ground in Ukraine is not “ruled out” after the issue was debated at a gathering of European leaders in Paris, as Russia’s full-scale invasion grinds into a third year. The French leader said that “we will do everything needed so Russia cannot win the war” after the meeting of more than 20 European heads of state and government, and other Western officials. “There’s no consensus today to send in an official, endorsed manner troops on the ground, but in terms of dynamics, nothing can be ruled out,” Macron said
