Chill your Netflix habit, climate experts say

  • Watching a half-hour show would lead to emissions of 1.6 kilograms of carbon dioxide equivalent
  • Last year, online video streaming produced emissions equivalent to Spain and that amount may double in the next six years

PARIS: Movie nights once required driving to the local video store to rent, rewind and return the latest blockbuster. Now on-demand video content providers offer countless binge-worthy options at the touch of a finger.
But experts say the ease of streaming services comes with a hefty environmental price tag.
Watching a half-hour show would lead to emissions of 1.6 kilograms of carbon dioxide equivalent, said Maxime Efoui-Hess of French think tank the Shift Project. That’s equivalent to driving 3.9 miles (6.28 kilometers).
Last year, online video streaming produced emissions equivalent to Spain and that amount may double in the next six years, according to the Shift Project.
While most of the online traffic — 34 percent — is related to streaming videos, on Netflix, Amazon Prime, and Hulu, for example, the next biggest sector is online porn.
“Digital videos come in very large file sizes and (are) getting bigger with each new generation of higher definition video,” said Gary Cook of Greenpeace, which monitors the IT sector’s energy footprint.
“More data equals more energy needed to maintain a system that is ready to stream this video to your device at a moment’s notice,” Cook told AFP.
Much of the energy needed for streaming services is consumed by the data center, which delivers data to your computer or device, explained Cook.
The centers contribute about 0.3 percent of all carbon emissions, according to an article by Nature.
Experts remain divided on how much that number will grow.
“For energy consumption to stay flat for the next five to 10 years, significant improvement in IT equipment and data center energy performance must be made or our appetite for computations must diminish,” said Dale Sartor of the Center of Expertise for Data Centers, linked to the US Department of Energy.
Anders Andrae of Huawei Technologies told AFP he estimated they would consume as much as 4.1 percent of global electricity by 2030.
Web-based video traffic is expected to increase four times from 2017 to 2022 and account for 80 percent of all Internet traffic by 2022, according to the CISCO Network.
Netflix is continuing to expand globally — the company reported a 53-percent increase in international revenue for streaming subscriptions between 2017 and 2018. And Disney and Apple are launching their own streaming services this year.
Meanwhile, the equipment used to view videos is getting larger — the average screen size shot up from 22 inches (55 centimeters) in 1997 to an expected 50 inches by 2021, according to the Consumer Technology Association.
“The changing screen size and related shift to digital video technology has set the stage for higher definition and thus larger file sizes that we are streaming,” said Cook.
Screens with 4K resolution use about 30 percent more energy than high-definition screens, according to a report by the Natural Resources Defense Council. Last year, 8K screens made their debut.
The consequence is “a waste of resources at all levels,” added Laurent Lefevre of the French Institute for Research in Computer Science and Automation.
Experts suggest that viewers disable autoplay and stream over Wi-Fi in lower-definition formats. The worst-case scenario is watching over a 3G connection on a mobile device, said Lefevre.
The Shift Project offers a browser extension that monitors Internet use, displaying the amount of electricty used, the CO2 that electricity produces, and how far the user would have to drive to match those emissions.
Cook emphasizes the most impactful change consumers can make is through their wallets.
“Exercising collective responsibility, with individuals demanding Internet giants rapidly transition their data centers to renewable energy, has been the biggest driver thus far,” he said.


‘Jetman’ stuns with Iron Man-style flight over Dubai

‘Jetman’ stuns with Iron Man-style flight over Dubai

  • The Frenchman hovered above Dubai’s coast before shooting off into the air and skimming the city’s skyline
  • Daredevil Vince Reffet’s carbon fiber wings are powered by four mini jet engines

DUBAI: Daredevil Vince Reffet has soared into the skies above Dubai in the latest “Jetman” stunt, taking off from the ground and climbing to 1,800 meters in a feat reminiscent of Marvel’s “Iron Man” and hailed as a world first.
Reffet and his collaborators, known as “Jetmen,” have literally scaled new heights with the help of jetpacks and carbon-fire wings, staging a series of aerial displays that send them tearing through the skies at breakneck speed.
In an awe-inspiring flight captured on viral video, the Frenchman on Friday hovered five meters above the crystal waters of Dubai’s coast before shooting off into the air and skimming the city’s skyline.


“We accomplished another world first in 100 percent autonomous human flight with @jetmandubai, who took off from the ground before soaring to a high-altitude flight of up to 1,800m!” tweeted Expo 2020 Dubai, the mammoth trade fair that will open in October.
The Jetmen had previously launched themselves into the air by jumping down from high platforms.
“It’s the result of extremely thorough teamwork, where each small step generated huge results. Everything was planned to the split second, and I was overjoyed by the progress that was achieved,” Reffet said in a statement.
“One of the next objectives is to land back on the ground after a flight at altitude, without needing to open a parachute. It’s being worked on.”

Reffet’s carbon fiber wings are powered by four mini jet engines. The equipment, which is controlled by the pilot’s movements, is capable of reaching speeds of 400 kilometers per hour.
On Friday, Reffet hovered five meters above the crystal waters of Dubai’s coast before shooting off into the air and skimming the city’s skyline.
The Jetmen have pulled off a series of eye-popping flights in Dubai, soaring in tandem above the world’s tallest building Burj Khalifa, and alongside an Emirates Airbus A380, the world’s largest commercial airplane.
Last year, Reffet and fellow Frenchman Fred Fugen also flew through the famed “Heaven’s Gate” archway in the mountains of China’s Hunan province.
