Renewables are widely recognized as an essential, non-polluting alternative energy source. But are they really as clean as they seem? When we examine solar, wind and other renewables, we tend to focus on the last mile while neglecting the full supply chain.

This is a dangerous oversimplification that ignores the hidden environmental and ethical costs associated with their production, transportation and disposal. To truly assess their efficiency and impact, this scrutiny must also be applied when comparing them with other energy sources.

Suppose we take solar energy, which has the lion’s share of global renewable energy capacity. Indeed according to the latest data, solar photovoltaic systems alone contributed to nearly 75 percent of the renewable capacity additions worldwide in 2023. In terms of electricity generation, solar PV accounted for about 4.5 percent of the global total.

This is clean energy but what about its full supply chain? 

The production of solar panels involves the use of hazardous materials like sodium hydroxide and hydrofluoric acid. Moreover, research indicates there is significant energy consumption leading to greenhouse gas emissions and potential water and land pollution from toxic waste such as cadmium and lead. 

The next step is transporting these panels. Most solar PV panels are produced in China, which dominates the global market. China and Taiwan together account for about 70 percent of the world’s solar cell and module production. Long distance freight adds to the carbon footprint. This adds approximately 0.02 to 0.05 pounds of CO2 per kilowatt-hour of electricity generated over the panel’s lifetime.

When we examine solar, wind, and other renewables, we tend to focus on the last mile while neglecting the full supply chain. This is a dangerous oversimplification.

Then, once solar panels reach the end of their lifespan, they ought to be recycled. However, the recycling process is close to nonexistent due to high costs and technical challenges. As such, many panels end up in landfill, contributing to soil and water pollution. It is estimated that by 2050, there could be around 6.5 million tonnes of solar panel waste.

This is why, when analyzing the benefits of a renewable source of energy, the entire scope and supply chain needs to be evaluated. And yet, to this day, we only focus on the last mile.

The same concept applies to electric cars. The entire supply chain must be analyzed — starting with the mines that extract the lithium, cobalt, nickel and graphite essential for making batteries, often under questionable ethical conditions.

I recently read the news of a fully electric building in the US, which was hailed as a great success. Yet its power sources were predominantly fossil fuels. And just how efficient are such structures, considering the loss of power in the grid and other factors such as the inherent inefficiency of electric heaters compared to gas-powered ones?

For all these reasons, it is important to pursue efforts to improve the sustainability of production, transportation, and recycling processes to mitigate these environmental impacts. It is even more important not to politicize the energy and environmental debate, as it will only lead to flawed decisions.

US federal judge blocks Trump effort to keep Harvard from hosting foreign students

US federal judge blocks Trump effort to keep Harvard from hosting foreign students
  • Homeland Security earlier withdrew the school’s certification to host foreign students after Harvard resisted Trump's interference
  • Harvard hosts roughly 7,000 international students, about a quarter of its total enrollment

WASHINGTON: A federal judge on Friday blocked the Trump administration’s efforts to keep Harvard University from hosting international students, delivering the Ivy League school another victory as it challenges multiple government sanctions amid a battle with the White House.
The order from US District Judge Allison Burroughs in Boston preserves Harvard’s ability to host foreign students while the case is decided, but it falls short of resolving all of Harvard’s legal hurdles to hosting international students. Notably, Burroughs said the federal government still has authority to review Harvard’s ability to host international students through normal processes outlined in law.
Harvard sued the Department of Homeland Security in May after the agency abruptly withdrew the school’s certification to host foreign students and issue paperwork for their visas, skirting most of its usual procedures. The action would have forced Harvard’s roughly 7,000 international students — about a quarter of its total enrollment — to transfer or risk being in the US illegally. New foreign students would have been barred from coming to Harvard.
The university said it was experiencing illegal retaliation for rejecting the White House’s demands to overhaul Harvard policies related to campus protests, admissions, hiring and more. Burroughs temporarily had halted the government’s action hours after Harvard sued.
Less than two weeks later, in early June, President Donald Trump tried a new strategy. He issued a proclamation to block foreign students from entering the US to attend Harvard, citing a different legal justification. Harvard challenged the move, saying the president was attempting an end-run around the temporary court order. Burroughs temporarily blocked Trump’s proclamation as well. That emergency block remains in effect, and Burroughs did not address the proclamation in her order Friday.
“We expect the judge to issue a more enduring decision in the coming days,” Harvard said Friday in an email to international students. “Our Schools will continue to make contingency plans toward ensuring that our international students and scholars can pursue their academic work to the fullest extent possible, should there be a change to student visa eligibility or their ability to enroll at Harvard.”
Students in limbo
The stops and starts of the legal battle have unsettled current students and left others around the world waiting to find out whether they will be able to attend America’s oldest and wealthiest university.
The Trump administration’s efforts to stop Harvard from enrolling international students have created an environment of “profound fear, concern, and confusion,” the university said in a court filing. Countless international students have asked about transferring from the university, Harvard immigration services director Maureen Martin said.
Still, admissions consultants and students have indicated most current and prospective Harvard scholars are holding out hope they’ll be able to attend the university.
For one prospective graduate student, an admission to Harvard’s Graduate School of Education had rescued her educational dreams. Huang, who asked to be identified only by her surname for fear of being targeted, had seen her original doctoral offer at Vanderbilt University rescinded after federal cuts to research and programs related to diversity, equity and inclusion.
Harvard stepped in a few weeks later with a scholarship she couldn’t refuse. She rushed to schedule her visa interview in Beijing. More than a month after the appointment, despite court orders against the Trump administration’s policies, she still hasn’t heard back.
“Your personal effort and capability means nothing in this era,” Huang said in a social media post. “Why does it have to be so hard to go to school?”
An ongoing battle
Trump has been warring with Harvard for months after the university rejected a series of government demands meant to address conservative complaints that the school has become too liberal and has tolerated anti-Jewish harassment. Trump officials have cut more than $2.6 billion in research grants, ended federal contracts and threatened to revoke Harvard’s tax-exempt status.
On Friday, the president said in a post on Truth Social that the administration has been working with Harvard to address “their largescale improprieties” and that a deal with Harvard could be announced within the next week. “They have acted extremely appropriately during these negotiations, and appear to be committed to doing what is right,” Trump’s post said.
Trump’s administration first targeted Harvard’s international students in April. Homeland Security Secretary Kristi Noem demanded that Harvard turn over a trove of records related to any dangerous or illegal activity by foreign students. Harvard says it complied, but Noem said the response fell short and on May 22 revoked Harvard’s certification in the Student and Exchange Visitor Program.
The sanction immediately put Harvard at a disadvantage as it competed for the world’s top students, the school said in its lawsuit, and it harmed Harvard’s reputation as a global research hub. “Without its international students, Harvard is not Harvard,” the lawsuit said.
The action would have upended some graduate schools that recruit heavily from abroad. Some schools overseas quickly offered invitations to Harvard’s students, including two universities in Hong Kong.
Harvard President Alan Garber previously said the university has made changes to combat antisemitism. But Harvard, he said, will not stray from its “core, legally-protected principles,” even after receiving federal ultimatums.

Trump says his intel chief was ‘wrong’ to believe Iran was not building a nuclear weapon
  • Also says Israeli strikes could be ‘very hard to stop’ now that they are “winning”
  • After Trump's remark, Tulsi Gabbard says her statement was taken out of context

WASHINGTON: President Donald Trump said Friday that his director of national intelligence, Tulsi Gabbard, was “wrong” when she previously said that the US believed Iran wasn’t building a nuclear weapon, and he suggested that it would be “very hard to stop” Israel’s strikes on Iran in order to negotiate a possible ceasefire.
Trump has recently taken a more aggressive public stance toward Tehran as he’s sought more time to weigh whether to attack Iran by striking its well-defended Fordo uranium enrichment facility. Buried under a mountain, the facility is believed to be out of the reach of all but America’s “bunker-buster” bombs.
After landing in New Jersey for an evening fundraiser for his super political action committee, Trump was asked about Gabbard’s comments to Congress in March that US spy agencies believed that Iran wasn’t working on nuclear warheads. The president responded, “Well then, my intelligence community is wrong. Who in the intelligence community said that?”
Informed that it had been Gabbard, Trump said, “She’s wrong.”
In a subsequent post on X, Gabbard said her testimony was taken out of context “as a way to manufacture division.”
“America has intelligence that Iran is at the point that it can produce a nuclear weapon within weeks to months, if they decide to finalize the assembly,” she wrote. “President Trump has been clear that can’t happen, and I agree.”
Still, disavowing Gabbard’s previous assessment came a day after the White House said Trump would decide within two weeks whether the US military would get directly involved in the conflict between Israel and Iran. It said seeking additional time was “based on the fact that there’s a substantial chance of negotiations that may or may not take place with Iran in the near future.”
But on Friday, Trump himself seemed to cast doubts on the possibility of talks leading to a pause in fighting between Israel and Iran. He said that, while he might support a ceasefire, Israel’s strikes on Iran could be “very hard to stop.”
Asked about Iran suggesting that, if the US was serious about furthering negotiations, it could call on Israel to stop its strikes, Trump responded, “I think it’s very hard to make that request right now.”
“If somebody is winning, it’s a little bit harder to do than if somebody is losing,” Trump said. “But we’re ready, willing and able, and we’ve been speaking to Iran, and we’ll see what happens.”
The president later added, “It’s very hard to stop when you look at it.”
“Israel’s doing well in terms of war. And, I think, you would say that Iran is doing less well. It’s a little bit hard to get somebody to stop,” Trump said.
Trump campaigned on decrying “endless wars” and has vowed to be an international peacemaker. That’s led some, even among conservatives, to point to Trump’s past criticism of the US invasion of Iraq beginning in 2003 as being at odds with his more aggressive stance toward Iran now.
Trump suggested the two situations were very different, though.
“There were no weapons of mass destruction. I never thought there were. And that was somewhat pre-nuclear. You know, it was, it was a nuclear age, but nothing like it is today,” Trump said of his past criticism of the administration of President George W. Bush.
He added of Iran’s current nuclear program, “It looked like I’m right about the material that they’ve gathered already. It’s a tremendous amount of material.”
Trump also cast doubts on Iran’s developing nuclear capabilities for civilian pursuits, like power generation.
“You’re sitting on one of the largest oil piles anywhere in the world,” he said. “It’s a little bit hard to see why you’d need that.”

Israel may have breached EU agreement, bloc’s foreign policy arm says

Israel may have breached EU agreement, bloc’s foreign policy arm says
  • EU-Israel pact requires “respect for human rights and democratic principles” for both sides
  • EU foreign ministers are set to discuss the review during a gathering in Brussels on Monday

BRUSSELS: The European Union’s diplomatic service said on Friday there were indications that Israel had breached its human rights obligations under the terms of a pact governing its ties with the bloc, according to a document seen by Reuters.
Citing assessments by independent international institutions, the European External Action Service said “there are indications that Israel would be in breach of its human rights obligations under Article 2 of the EU-Israel Association Agreement.”
The report comes after months of deepening concern in European capitals about Israel’s operations in Gaza and the humanitarian situation in the enclave.
“Israel’s continued restrictions to the provision of food, medicines, medical equipment, and other vital supplies affect the entire population of Gaza present on the affected territory,” the document said.

Asked about the EU review, an Israeli official called it “a one-sided report that exemplifies the double standards the EU uses toward Israel.”
Under the EU-Israel Association Agreement, which came into force in 2000, the EU and Israel agreed that their relationship “shall be based on respect for human rights and democratic principles.”
The EU’s top diplomat, Kaja Kallas, announced in May that the bloc would examine whether Israel was complying with the terms of the pact, after over half of EU members backed the conducting of a review.
The report includes a section dedicated to the situation in Gaza, covering issues related to denial of humanitarian aid, attacks with a significant number of casualties, attacks on hospitals and medical facilities, displacement, and lack of accountability.

The report also looks at the situation in the West Bank, including settler violence.
The document relies on “facts verified by and assessments made by independent international institutions, and with a focus on most recent events in Gaza and the West Bank,” it said.
Israel has said that it respects international law and that operations in Gaza are necessary to destroy Hamas, the Palestinian group responsible for the Oct. 7, 2023, attacks on Israel.
EU foreign ministers are set to discuss the review during a gathering in Brussels on Monday. Member countries remain divided in their approach to Israel.
While some ministers could advocate for moving toward taking action based on the review, no concrete decisions are expected at Monday’s session.
Diplomats expect EU officials will reach out to Israel with the outcome of the review in an effort to influence it, and that ministers will return to the subject during a July meeting.

Columbia protester Mahmoud Khalil freed from immigration detention

Columbia protester Mahmoud Khalil freed from immigration detention
  • Khalil, a Columbia University student, who became a leader of pro-Palestinian campus protests has been in custody since March facing deportation
  • District Judge Michael Farbiarz ordered Khalil’s release on bail allowing him to return to New York while his case proceeds

JENA, Louisiana: Palestinian activist Mahmoud Khalil was released Friday from federal immigration detention, freed after three months by a judge’s ruling after becoming a symbol of President Donald Trump ‘s clampdown on campus protests.
The former Columbia University graduate student left a federal facility in Louisiana on Friday. He is expected to head to New York to reunite with his US citizen wife and newborn son.
The Trump administration sought to deport him over his role in pro-Palestinian protests
“Justice prevailed, but it’s very long overdue,” he said outside the facility in a remote part of Louisiana. “This shouldn’t have taken three months.”
Khalil was released after US District Judge Michael Farbiarz said it would be “highly, highly unusual” for the government to continue detaining a legal US resident who was unlikely to flee and hadn’t been accused of any violence.
“Petitioner is not a flight risk and the evidence presented is that he is not a danger to the community,” he said. “Period, full stop.”
Later in the hourlong hearing, which took place by phone, the judge said the government had “clearly not met” the standards for detention.
The government filed notice Friday evening that it’s appealing Khalil’s release.
Khalil had to surrender his passport and can’t travel internationally, but he will get his green card back and be given official documents permitting limited travel within the country, including New York and Michigan to visit family, New Jersey and Louisiana for court appearances and Washington to lobby Congress.
Khalil was the first person arrested under President Donald Trump ‘s crackdown on students who joined campus protests against Israel’s devastating war in Gaza. US Secretary of State Marco Rubio has said Khalil must be expelled from the country because his continued presence could harm American foreign policy.
Farbiarz had ruled earlier that the government couldn’t deport Khalil on those grounds, but gave it leeway to continue pursuing a potential deportation based on allegations that he lied on his green card application. Trump administration lawyers repeated that accusation at Friday’s court hearing. It’s an accusation Khalil disputes.
In issuing his ruling Friday, the judge agreed with Khalil’s lawyers that the protest leader was being prevented from exercising his free speech and due process rights despite no obvious reason for his continued detention. The judge noted that Khalil is now clearly a public figure.
Khalil’s lawyers had asked that he either be freed on bail or, at the very least, moved from Louisiana to New Jersey so he can be closer to his wife and newborn son, who are both US citizens.
Khalil’s wife, Dr. Noor Abdalla, said she can finally “breathe a sigh of relief” after her husband’s three months in detention.
“We know this ruling does not begin to address the injustices the Trump administration has brought upon our family, and so many others,” she said in a statement provided by Khalil’s lawyers. “But today we are celebrating Mahmoud coming back to New York to be reunited with our little family.”
The judge’s decision comes after several other scholars targeted for their activism have been released from custody, including another former Palestinian student at Columbia, Mohsen Mahdawi; a Tufts University student, Rumeysa Ozturk; and a Georgetown University scholar, Badar Khan Suri.
Khalil was detained on March 8 at his apartment building in Manhattan over his participation in pro-Palestinian demonstrations.
The international affairs graduate student isn’t accused of breaking any laws during the protests at Columbia. He served as a negotiator and spokesperson for student activists and wasn’t among the demonstrators arrested, but his prominence in news coverage and willingness to speak publicly made him a target of critics.
The Trump administration has argued that noncitizens who participate in such demonstrations should be expelled from the country as it considers their views antisemitic.

Morocco says 2024 ‘hottest year’ on record

Morocco says 2024 ‘hottest year’ on record
  • Moroccan climatologist Mohammed-Said Karrouk, who also heads Morocco’s National Future Planet Committee, warned that the kingdom’s geography and climate make it more vulnerable to temperature extremes

RABAT: The year 2024 was Morocco’s hottest on record, the North African country’s meteorological agency said on Friday, mirroring the record surface temperatures measured globally.
In an annual report, the agency said it recorded an average temperature anomaly of +1.49 degrees Celsius (+2.7 Fahrenheit) last year compared to the 1991-2020 period.
“The year 2024 stands out as the hottest ever recorded in Morocco,” it said, adding that every month in 2024, excluding June and September, had been hotter than the average for the 1991-2020 reference period.
Several cities broke daily heat records, with 47.6 degrees Celsius (117.7 Fahrenheit) in Marrakech and 47.7 degrees Celsius (117.8 Fahrenheit) in Beni Mellal in July last year, the agency said.
It also noted “an increase in thermal anomalies, particularly during the autumn and winter seasons.”
Morocco’s all-time heat record was set in August 2023, when temperatures hit 50.4 degrees Celsius (122 Fahrenheit) in Agadir.
The country, which is enduring a seventh straight year of drought, registered an average rainfall deficit of -24.7 percent last year, the report said.
The agency said last year’s data reflected “an amplification of climate contrasts in Morocco, where prolonged droughts alternate with episodes of extreme precipitation.”
Torrential rains in September 2024 — causing floods and killing 18 people — “did not reverse the overall rainfall deficit,” it added.
Moroccan climatologist Mohammed-Said Karrouk, who also heads Morocco’s National Future Planet Committee, warned that the kingdom’s geography and climate make it more vulnerable to temperature extremes.
He said warming was now observed in all seasons.
“In autumn, lingering summer heat combined with gradually cooling temperatures favors violent downpours, which have become more dangerous due to excess humidity in the atmosphere,” he said.
“In winter, the heat originating mostly from warming tropical oceans now influences North Africa as well.”
A former member of the UN Intergovernmental Panel on Climate Change, Karrouk also warned of a recent intensification of the West African monsoon — a seasonal wind system that brings moist air from the Atlantic Ocean — which he linked to the deadly September floods.
He called for the construction of shelters to protect vulnerable populations and dams to capture water — a valuable resource with Morocco’s unrelenting drought.
Weather extremes have taken a toll on farming, a vital sector for Morocco which employs nearly a third of its active population and accounts for 12 percent of GDP.
Scientists say that recurring heatwaves are a clear marker of global warming and that they are set to become more frequent, longer and more intense.
Fuelled by human-driven climate change, 2024 was the warmest year on record globally — and 2025 is projected to rank among the top three.
