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.

Johar added that the agreement aligns with the National Aviation Strategy’s goal of operating a world-class, sustainable airport with high energy efficiency standards, consistent with Vision 2030.

He highlighted KAIA’s achievements in environmental preservation, including sustainability projects such as a recycling initiative that reduces carbon emissions and achieves net-zero targets, electricity and water conservation projects utilizing solar panels and smart technologies, and air quality monitoring in collaboration with the National Center for Environmental Compliance.

He said that the airport has increased green spaces to mitigate carbon emissions.

Established in 2017, Tarshid specializes in retrofitting buildings and facilities to improve energy efficiency and sustainability across government and private sectors. The KAIA project is among its key initiatives with the private sector, aiming to encourage the aviation industry to adopt sustainable practices.

By the end of the third quarter of this year, the company had achieved annual energy savings of 7.3 terawatt-hours across various projects, equivalent to conserving over 11.7 million barrels of oil equivalent and avoiding approximately 4.2 million metric tonnes of harmful emissions. These efforts equate to the environmental impact of planting more than 69.4 million seedlings annually, SPA reported.

Tarshid has recently signed a similar agreement with SAL Logistics Services, underscoring its role in advancing energy efficiency and sustainability across both governmental and private sectors.

Asian countries mark 20 years since the world’s deadliest tsunami

Asian countries mark 20 years since the world’s deadliest tsunami
  • Indonesia launched its early tsunami warning system in the aftermath of the 2004 disasters
  • Its westernmost Aceh province was the hardest-hit, with some 170,000 people killed

JAKARTA: Herman Wiharta began that Sunday morning like many 11-year-olds would on a weekend: watching cartoon shows on TV.

But at around 8 a.m., he felt the powerful tremors from a 9.1-magnitude earthquake that struck off the coast of Indonesia’s Sumatra island, which then triggered the tsunami that inundated the coastline of more than a dozen countries and killed some 230,000 people.

Wiharta, now 31, recalled his brother calling out to him to leave their house in Banda Aceh minutes after the quake and how they had attempted to run to safety. He remembered hearing people scream about the rising sea water before he himself was swept away by a giant wave.

“I lost consciousness when the wave hit me and I woke up on a roof, confused. Thankfully, my brother and sister were also on that roof,” he told Arab News.

“We were able to see just how black the water was from that spot, how strong the currents were. The water was about 4 to 5 meters high; cars and motorbikes were floating, and I could see bodies being swept away by the currents, too. It was terrifying.”

The tsunami on Dec. 26, 2004 quickly escalated into a global disaster, with some 1.7 million displaced.

The brunt of the tsunami was felt in Indonesia, where almost 170,000 people perished. The country’s westernmost province of Aceh was the hardest-hit of all, while Sri Lanka, India and Thailand were among the worst-affected countries.

“It was impossible to sleep that night. We could still hear people screaming for help and the dogs were howling. Everything was just so eerie. The disasters happened so quickly, but they were deeply traumatizing,” Wiharta said.

“It was even worse the day after. We could see bloated human and animal corpses, and the smell was just terrible. I can still picture that scene in my mind to this day.”

Across Asia on Thursday, people attended ceremonies and memorials held to mark 20 years since the deadliest tsunami in recorded history.

Coastal communities were united in grief as they also commemorated how far they had come after two decades of rebuilding and regrouping.

In Sri Lanka, where more than 35,000 people were killed, survivors and relatives gathered in the coastal village of Peraliya to remember the 1,000 victims who died when waves derailed a passenger train.

In Thailand, where half of the death toll of 5,000 were foreign tourists, commemorations were held in Ban Nam Khem, the country’s worst-hit village. People laid flowers and wreaths at a wall curved in the shape of a tsunami, which also bears plaques with the names of the victims.

In India, where around 20,000 people perished, women led the rituals held at Pattinapakkam beach in Chennai, where they lit candles and offered flowers for the victims.

In Banda Aceh city, an official ceremony held at the Baiturrahman Grand Mosque began with a three-minute-long siren at the exact time the major earthquake caused giant waves. People also gathered for prayers at the city’s mass graves — Ulee Lheue and Siron — where thousands of unidentified and unclaimed tsunami victims are buried.

In the years since, infrastructure across Aceh has been rebuilt and is now stronger to withstand major disasters. Early warning systems have also been set up in areas closer to shores, to warn residents of a potential tsunami.

Indonesia’s early tsunami warning system was launched only in 2008 in the aftermath of the disasters, said Daryono, the head of the earthquake and tsunami center at Indonesia’s meteorology, climatology and geophysical agency.

“Before the 2004 Aceh earthquake and tsunami … there were too many people who did not understand the threat, or the danger and risks of a tsunami,” Daryono told Arab News.

“But what happened in 2004 became a starting point to raise awareness on earthquake and tsunami mitigation and also to develop high-tech monitoring for earthquakes and early tsunami warning systems.”

Yet Aceh resident Wiharta was concerned with the direction of development in the province, particularly on the beaches of Aceh Besar district where many new cafes have been popping up in recent years.

“It’s important not to cut down the trees for the sake of building these cafes. It’s better to plant more trees, especially mangroves, so that they can help defend against potential tsunamis,” he said.

“I think the early warning systems also need to be fixed or reset to make sure that they are properly working for early evacuations, since many are either broken or stolen.”

Lebanon hopes for neighborly relations in first message to new Syria government

Lebanon hopes for neighborly relations in first message to new Syria government
  • Lebanon’s Iran-backed Hezbollah played a major part propping up Syria’s ousted President Bashar Assad through years of war
  • Syria’s new Islamist de-facto leader Ahmed Al-Sharaa is seeking to establish relations with Arab and Western leaders

DUBAI: Lebanon said on Thursday it was looking forward to having the best neighborly relations with Syria, in its first official message to the new administration in Damascus.
Lebanese Foreign Minister Abdallah Bou Habib passed the message to his Syrian counterpart, Asaad Hassan Al-Shibani, in a phone call, the Lebanese Foreign Ministry said on X.
Lebanon’s Iran-backed Hezbollah played a major part propping up Syria’s ousted President Bashar Assad through years of war, before bringing its fighters back to Lebanon over the last year to fight in a bruising war with Israel – a redeployment which weakened Syrian government lines.
Under Assad, Hezbollah used Syria to bring in weapons and other military equipment from Iran, through Iraq and Syria and into Lebanon. But on Dec. 6, anti-Assad fighters seized the border with Iraq and cut off that route, and two days later, Islamist militants captured the capital Damascus.
Syria’s new Islamist de-facto leader Ahmed Al-Sharaa is seeking to establish relations with Arab and Western leaders after toppling Assad.
