Sam Altman defends AI’s energy toll by saying it also takes a lot to ‘train a human’

The OpenAI boss, Sam Altman, has tried to ease concerns about how much power is used by artificial intelligence models by comparing it to the amount of energy required by human development,“People talk about how much energy it takes to train an AI model – but it also takes a lot of energy to train a human,” Altman told the Indian Express recently while in India for the AI Impact summit,“It takes about 20 years of life – and all the food you consume during that time – before you become smart,”Despite that defense, he said that the public assessment of AI’s energy consumption was “fair”, adding: “We need to move towards nuclear or wind and solar very quickly,”Those remarks come amid growing discussion about the environmental impact of the datacenters required to power AI models – and, more generally, about technology’s possible impact on society.

Datacenters accounted for about 1.5% of global electricity consumption in 2024, according to the International Energy Agency.The organization projects that such consumption will increase about 15% each year from 2024 to 2030, more than four times faster than the growth of electricity consumption from all other sectors.“The demand for new datacenters cannot be met in a sustainable way,” Noman Bashir, a computing and climate impact fellow at the Massachusetts Institute of Technology’s climate and sustainability consortium, told MIT’s news outlet.“The pace at which companies are building new datacenters means the bulk of the electricity to power them must come from fossil fuel-based power plants.

”In December, more than 230 environmental groups called for a moratorium on building datacenters in the US.“The rapid, largely unregulated rise of datacenters to fuel the AI and crypto frenzy is disrupting communities across the country and threatening Americans’ economic, environmental, climate and water security,” their letter states.At the AI conference, Altman also downplayed concerns about the water datacenters require.“Water is totally fake.It used to be true.

We used to do evaporative cooling in datacenters, but now … we don’t do that,” Altman said,“You see things on the internet, [like]: ‘Don’t use ChatGPT,It’s 17 gallons of water for each query or whatever,’ This is completely untrue – totally insane,”CNBC reported that “some newer data centers no longer rely on water at all”.

The director of the Southern New Hampshire University office of sustainability, Mike Weinstein, told the Guardian he was skeptical of the argument from Altman and other AI advocates that the power such infrastructure demands is justified because the technology will help alleviate global problems.A September 2025 report from OpenAI on how people use ChatGPT found that 70% of messages to the bot were not work related.“It didn’t look like the majority of use of that was for figuring out how we solve challenges in food systems and energy systems, so that would be my skepticism of saying this technology is worth it because I have yet to see it demonstrated,” Weinstein said.Altman’s remarks generated a backlash online, with some people describing them as dystopian.“He’s saying a really big spreadsheet and a baby are morally equivalent,” Matt Stoller, research director at the American Economic Liberties Project, posted on X.

“One reason to believe that life is divine is so that you don’t allow sociopaths like this anywhere near anything important.”The sports commentator and TV host Jeff Johnson compared Altman’s comments to the Netflix series Black Mirror, which explores potential harms from new technology.“Notice the disturbing techy parlance that he uses to describe the general human experience,” Johnson wrote on X.“Training?!’ Too many people are falling for [it].Y’all really lettin these geeks destroy the Earth.

Government accused of caving in to building lobby amid plans to shake up housing sector in England

The government has been accused of bowing to lobbying by housebuilders, in proposals that would prevent English local authorities from pursuing improvements to low-carbon homes standards.Under a consultation on planning rules, councils would be issued with guidance that would effectively limit their scope to demand builders construct new homes within their areas to the highest possible standards.These changes to the National Planning Policy Framework would benefit housebuilders, which could be assured of the same standards across England, but would bind the hands of councils, some of which have declared a “climate emergency”.Ministers have yet to publish separate much-delayed rules for the future homes standard (FHS), which requires new homes to be built with low-carbon equipment such as heat pumps, high-grade insulation and solar panels. But there are fears that the FHS will not go far enough

Tell us your experience living with Tourette syndrome

Controversy erupted at the Baftas award ceremony after the BBC initially failed to edit out the N-word spoken involuntarily by John Davidson, who has Tourette syndrome (TS).In a statement Davidson said he was “deeply mortified if anyone considers my involuntary tics to be intentional or to carry any meaning”. He added: “I have spent my life trying to support and empower the Tourette’s community and to teach empathy, kindness and understanding from others and I will continue to do so. I chose to leave the auditorium early into the ceremony as I was aware of the distress my tics were causing.”We would like to hear from people who are affected by Tourette syndrome (TS), and in particular those who have vocal tics involving swearing (coprolalia)

My maddening battle with chronic fatigue syndrome: ‘On my worst days, it feels almost demonic’

At the Croydon secondary school I attended in the late 1990s, the deputy headmistress was a stocky woman with a military haircut who patrolled the corridors in voluminous outfits patterned in shades of brown. The outfits were much discussed, not charitably, by the teenage girls in her charge – as was her voice, which made you think of a blunt knife being drawn across a rough surface. Thirty years later, I can still hear that terrible voice refer to my “mystery illness”. In truth, the deputy headmistress never actually spoke those words – they were included in a typed letter she sent to my parents concerning my prolonged absence from school. Still, the indicting force of five syllables is as distinct in my ear as if she were looming over me

Unlicensed gambling firms could be barred from sponsoring Premier League clubs

Unlicensed gambling firms could be barred from sponsoring Premier League football clubs, after a string of controversies involving pornographic videos, failures in anti-money laundering rules and concerns about links to organised crime.Shirts worn by players for several major English football teams, including Everton, Fulham and Burnley, feature the logos of unlicensed online casinos or bookmakers.Premier League clubs have pledged to end all front-of-shirt gambling deals from the end of this season, including those with large operators with a licence.But the voluntary measure will not apply to shirt sleeves or other commercial tie-ups. This leaves the door open to gambling firms who do not hold a British licence to continue hitching themselves to the popularity of the Premier League, as long as they promise not to offer their services to UK consumers

What is Tourette syndrome, what are tics and what happened at the Baftas?

Controversy has erupted over the Baftas after the BBC initially failed to edit out a racial slur shouted by John Davidson, who has Tourette syndrome (TS). Here we explore what vocal tics are, and how they should be understood.One of the films up for awards was I Swear – a movie inspired by the real-life story of the TS campaigner Davidson, who was present at the event on Sunday.Davidson shouted several times during the ceremony. In one case, he used the N-word while the actors Delroy Lindo and Michael B Jordan were presenting a prize on stage
