Tech’s carbon footprint: can AI revolutionize responsibly?

Published

on

The transformation of the world’s data servers to become AI-ready is well underway
Share this:

Across the globe, data servers are humming, consuming both megawatts and precious natural resources to bring life to our digital world.

The planet’s 8,000 or so data centers are the foundation of our online existence, and will grow ever further with the advent of artificial intelligence — so much so that research estimates that by 2025, the IT industry could use 20 percent of all electricity produced, and emit up to 5.5 percent of the world’s carbon emissions.

This poses a real — and to some, increasingly urgent — question about the industry’s carbon footprint as startups and companies fall behind Silicon Valley’s latest forward march.

“Pandora’s box is open,” said Arun Iyengar, CEO of Untether AI, a highly specialized chip-making company that strives to make AI more energy efficient.

“We can utilize AI in ways that enhance the climate requirements or we can ignore the climate requirements and find ourselves facing the consequences in a decade or so in terms of the impact.”

The transformation of the world’s data servers to AI readiness is already well underway, in what one Google executive called a “once-in-a-generation inflection point in computing.”

But the scope of the mission is huge.

The creation of generative AI tools such as GPT-4, which powers ChatGPT, or Google’s Palm2, behind the bot Bard, can be broken into two key stages, the actual “training” and then the execution (or “inference”).

In 2019, University of Massachusetts Amherst researchers trained several large language models, and found that training a single AI model can emit the CO2 emission equivalent of five cars over their lifetimes.

A more recent study by Google and the University of California, Berkeley, reported that training GPT-3 resulted in 552 metric tons of carbon emissions, equivalent to driving a passenger vehicle 1.24 million miles (2 million kilometers).

OpenAI’s latest generation model, GPT-4, is trained on around 570 times more parameters — or inputs — than GPT-3, and the scale of these systems will only grow as AI becomes more powerful and ubiquitous.

Nvidia, AI’s chip giant, provides the processors that are indispensable for training, known as GPUs. And while they are more energy efficient than typical chips, they remain formidable consumers of power.

– The ChatGPT ‘problem’ –

The other side of generative AI is deployment, or inference: when the trained model is applied to identify objects, respond to text prompts or whatever the use case may be.

Deployment doesn’t necessarily need the computing heft of a Nvidia chip, but taken cumulatively, the endless interactions in the real world far outweigh training in terms of workload.

“Inference is going to be even more of a problem now with ChatGPT, which can be used by anyone and integrated into daily life through apps and web searches,” said Lynn Kaack, assistant professor of computer science at the Hertie School in Berlin.

The biggest cloud companies insist that they are committed to being as energy efficient as possible.

Amazon Web Services pledges to be carbon-neutral by 2040 while Microsoft has pledged to be carbon-negative by 2030.

The latest evidence that the companies are serious about energy efficiency is reassuring.

Between 2010 and 2018, global data center energy use rose by only 6 percent, despite a 550 percent increase in workloads and computing instances, according to the International Energy Agency.

– ‘Backwards’ thinking –

Silicon Valley’s AI tycoons believe discussions of AI’s current carbon footprint are beside the point, and underplay its revolutionary potential.

The naysayers have it “backwards,” Nvidia CEO Jensen Huang told reporters on a recent visit to his company’s headquarters in California.

The mass deployment of AI and faster computing will in the end diminish the need to go to the world’s data clouds, he argued.

AI’s superpowers will turn your laptop, car or the device in your pocket into an energy-efficient supercomputer without the need to “retrieve” data from the cloud.

“In the future, there’ll be a little tiny model that sits on your phone and 90 percent of the pixels will be generated, 10 percent will be retrieved, instead of 100 percent retrieved — and so you’re going to save (energy),” he said.

OpenAI’s Sam Altman meanwhile believes that AI will soon enough be able to build humanity a completely new future.

“I think once we have a really powerful super intelligence, addressing climate change will not be particularly difficult,” Altman said recently.

“This illustrates how big we should dream… Think about a system where you can say, ‘Tell me how to make a lot of clean energy cheaply, tell me how to efficiently capture carbon, and tell me how to build a factory to do this at planetary scale.'”

But some experts worry that the mad dash for AI has elbowed out fears about the planet, at least for now.

“Large corporations are spending a lot of money right now deploying AI. I don’t think they are thinking about the environmental impact yet,” said Untether AI’s Iyengar.

But, he added: “I think that is coming.”

TikTok reaches music licensing deal with Universal, ending feud

Published

The Universal-TikTok deal ends closely watched negotations that saw a breakdown earlier this year as two of the most powerful players in the music and tech industries publicly criticized each other as they jockeyed for leverage
Share this:

TikTok and Universal announced a new licensing agreement Thursday, ending a months-long dispute that saw popular music expunged from the social media platform.

The companies released a joint statement that said the new deal included “improved remuneration” for artists and songwriters under the Universal Music Group (UMG) umbrella, and will also assuage concerns over the growth of AI-generated content on TikTok.

Universal chairman Sir Lucian Grainge said “this new chapter in our relationship” would “drive innovation in fan engagement while advancing social music monetization.” 

The deal “focuses on the value of music, the primacy of human artistry and the welfare of the creative community,” he said.

TikTok’s CEO Shou Chew similarly said “we are committed to working together to drive value, discovery and promotion for all of UMG’s amazing artists and songwriters, and deepen their ability to grow, connect and engage with the TikTok community.”

The deal wraps up closely watched negotiations that saw a breakdown earlier this year, with the companies — two of the most powerful players in the music and tech industries — publicly criticizing each other as they jockeyed for leverage.

Universal — whose roster of artists includes Taylor Swift, Drake and Billie Eilish — ordered music from all artists connected to its vast publishing catalog to come down off the app, leaving many concerned over losing the marketing potential TikTok can offer.

Millions of videos involving Universal artists became muted on the platform.

But while the stripped music will now return to TikTok, it comes at a moment of uncertainty for the wildly popular video-sharing app, one week after a new US law demands the company divest from its Chinese parent company ByteDance or be shut out of the American market.

The app has 170 million users in the United States alone.

Neither Universal nor TikTok disclosed any financial terms of the deal.

Several weeks ago, the powerful and popular Swift returned some of her music to the app ahead of the release of her most recent album.

It was unclear exactly how she did it, but Swift does own her own master recordings as well as her songwriting rights, though those two are administered by Universal’s publishing arm.

In their joint statement the companies said they were “working expeditiously to return music by artists represented by Universal Music Group and songwriters represented by Universal Music Publishing Group to TikTok in due course.”

Changpeng Zhao, the ‘normal guy’ who conquered crypto

Published

Changpeng Zhao pleaded guilty to violating US anti-money laundering laws and agreed to step down as Binance CEO
Share this:

During his time at the helm of the world’s biggest cryptocurrency firm, former Binance boss Changpeng Zhao, who will be sentenced in the United States later Tuesday for money laundering, perfected the humble executive look.

At parties, on stages and in meetings, he was rarely seen without his black polo shirt, emblazoned with the insignia of his firm — complemented by the corporate logo tattooed on his arm.

It was vital to cement the myth of a boy who came from hardship in China and once flipped burgers for a living in Canada — before making a fortune still estimated in the tens of billions.

“I’m a small entrepreneur,” and a “normal guy”, the man known in crypto circles as “CZ” told AFP in 2022 when comparing himself to Elon Musk, whose buyout of Twitter (now X) Zhao later backed with $500 million.

Yet there was little normal about Zhao’s leadership of Binance, a company that largely cornered the crypto-trading market before careening into a slew of charges including sanctions busting and illegal trading. 

Zhao, who founded Binance in Shanghai in 2017, emerged as the most visible figure in crypto after his great rival Sam Bankman-Fried was arrested in 2022 for masterminding a giant Ponzi scheme.

During his rival’s downfall, Zhao was there to twist the knife, first suggesting he might buy FTX before very publicly withdrawing.

A year later, it was Zhao’s turn for contrition.

He pleaded guilty to violating US anti-money laundering laws and agreed to step down as Binance CEO, the authorities announcing later that the firm would pay a $4.3 billion settlement.

– True grit? –

The legal cases painted a picture of Zhao as a ruthless operator pursuing growth at all costs.

It was a far cry from the folksy legend he had fostered, which had become almost mythical in crypto circles.

Zhao’s early life in China was scarred by hardship when his parents were sent to the countryside for a dose of peasant reality — a common punishment for those suspected of having capitalist sympathies during the Cultural Revolution of the 1960s and 1970s.

They emigrated to Canada in the late 1980s, where young Zhao worked at a McDonald’s and a petrol station to help the family survive, according to his own account of his life and a blog from 2020 on the Binance website.

This instilled “drive, grit, and initiative” into the young man and helped to create a “crypto leader”, the Binance blog said.

Zhao’s nomadic childhood informed his adult life, which has seen him crop up everywhere from New York to Tokyo.

The official legend has it that he caught the bitcoin bug during a conversation around a poker table in Shanghai in 2013, starting Binance in the Chinese city a few years later.

Beijing’s crackdown on crypto hastened his departure from China and he began his voyage through various jurisdictions, establishing a raft of complicated corporate structures on his way.

For years, he kept regulators at arm’s length by refusing to commit to a single jurisdiction for Binance’s headquarters, repeatedly saying it was a “complex issue”.

The stance made him a popular figure among crypto purists who loathe any form of regulation.

– ‘Good old times’ –

But the whiff of scandal finally got too strong for US market regulators, who labelled Binance’s compliance regime a “sham” and accused Zhao of orchestrating a “secret plot” to help VIP customers evade the law.

Then the law enforcement authorities came knocking.

Among other complaints, they accused Binance of failing to stop payments to the Islamic State militant group and other banned organisations in Iran and North Korea.

Unlike Bankman-Fried, Zhao was quick to admit guilt and avoid a high-profile trial.

But prosecutors are asking the court in Seattle to dole out a three-year prison sentence to Zhao.

In response to his troubles, Zhao has fallen back on his everyman persona.

He launched a start-up in March called the Giggle Academy that he said would aim to bring free education to underprivileged children around the world.

“Start up mode all over again. Like good old times,” he wrote on X in early April, just weeks before he was due to be sentenced.

Among the subjects he is aiming to teach? Blockchain, AI and finance.

G7 to phase out coal-fired power plants by mid-2030s

Published

The mid-2030s phase out agreed by G7 ministers has been described as 'too late' by environmentalists
Share this:

G7 ministers agreed a timeframe Tuesday for phasing out coal-fired power plants, setting as a goal the mid-2030s, in a move hailed as significant by some environmentalists but slammed as “too late” by others.

The Group of Seven two-day meeting in Turin was the first big political session since the world pledged at the UN’s COP28 annual climate summit in Dubai in December to transition away from coal, oil and gas.

The G7 commits to “phase out existing unabated coal power generation in our energy systems during the first half of 2030s,” the final statement from energy and climate ministers read.

However it left some wiggle room, saying nations could follow “a timeline consistent with keeping a limit of 1.5-degrees-Celsius temperature rise within reach, in line with countries’ net zero pathways”.

It also preserved a place for coal power if it is “abated”, meaning its emissions are captured or limited by technology — something panned by many as unproven and a distraction from cutting fossil fuel use.

The G7 brings together Canada, France, Germany, Italy, Japan, the UK and US. 

Negotiations over a fixed date were reportedly tricky. Some countries, and many environmentalists, had been pushing for a 2030 limit, but Japan — which relies heavily on coal — was reluctant to set a date.

The leaders of the G7 countries will produce their own statement after a summit in southern Italy in June.

– ‘What about gas?’ –

The 2015 Paris Agreement saw countries agree to cap global warming at “well below” 2C above preindustrial times — with a safer limit of 1.5C if possible.

To keep the 1.5C limit in play, the UN’s climate expert panel has said emissions need to be slashed almost in half this decade, but they continue to rise.

The International Energy Agency (IEA) has said that to reach net zero emissions by 2050 — a key milestone to limit global warming — advanced economies should end all generation by unabated coal-fired power plants by 2030.

Italian Environment and Energy Security Minister Gilberto Pichetto Fratin said the talks had been “intense” but showed the G7 had “grasped” climate change.

Luca Bergamaschi from the Italian climate think tank ECCO said the G7 had taken a “decisive step forward” in translating the Dubai agreement into national policies.

The World Resources Institute hailed the commitment as “a beacon of hope for the rest of the world”.

But Oil Change International said the G7 “have failed” their first post-COP28 test, while the Climate Analytics policy institute said “2035 is too late”.

“Many of these countries have already publicly committed to phase out dates ahead of 2030, and only have a small amount of coal capacity anyway,” Jane Ellis from Climate Analytics said in a statement.

She also pointed out it was “notable that gas has not been mentioned”, despite it being the largest source of the global increase in CO2 emissions in the last decade.

Germany — Europe’s biggest emitter of greenhouse gases — is unwilling to wean off gas, as is G7 host Italy, which is investing in new domestic gas facilities.

– ‘Capable of contributing’ –

The G7 ministers did say they will scale-up battery storage “more than sixfold” by 2030, to support electricity grids powered by renewable energy sources.

They also tackled the thorny issue of plastic pollution amid a heated debate over how to best design a treaty addressing the scourge. 

Plastic waste is now found everywhere from the summits of mountains to the ocean floor and in human blood and breast milk. 

Broadly, the debate is between whether to focus on reducing production, or boosting recycling.

The ministers said they “aspired” to reduce and if necessary restrain the global production of plastic, and renewed their commitments to end plastic pollution by 2040.

Climate watchers are pushing for more funds for adaptation to climate change and energy systems for developing countries, and all eyes will be on the G7 finance minister’s meeting in at the end of May.

The ministers in Turin stressed efforts to raise money to help poorer countries deal with climate change should include “those countries that are capable of contributing”.

Under a UN climate treaty signed in 1992, only a small handful of high-income countries that dominated the global economy at the time were required to pay climate finance — not including China, which has since become wealthier, and is now the world’s largest polluter.

“By making it clear that we were calling on other countries to contribute, we want China to join us in this direction,” Franck Riester, the minister representing France on climate issues, told AFP.
