Vast datacentres are being built worldwide, amid growing concerns about the environmental costs. So should we all be considering a data diet – if not complete digital sobriety? Nearly 20 years ago, the British mathematician Clive Humby coined a snappy phrase that has turned into a platitude: “data is the new oil”. He wasn’t wrong. We have an insatiable appetite for data, we can’t stop generating it, and, just like oil, it’s turning out to be bad news for the environment. So the Guardian set me a challenge: to try to give a sense of how much data an average person uses in a day, and what the carbon footprint of normal online activity might be. To do that, I tried to tot up the sorts of things I and millions of others do every day, and how that tracks back through the melange of messaging services, social networks, applications and tools, to the datacentres that keep our digital lives going.

The project that began in the Canary Islands mimics the way leaves capture water droplets from fog in order to produce water They call it cloud milking, a zero-energy technique to extract water from fog that is revolutionising the recovery of forests devastated by fire and drought. The idea began as a pilot project in the Canary Islands. The plan was to exploit the moisture-laden “sea of clouds” that hangs over the region in order to aid reforestation, and has since been extended to several other countries to produce drinking water, and to irrigate crops.

Tech company orders six or seven small nuclear reactors from California’s Kairos Power * Business live – latest updates Google has signed a “world first” deal to buy energy from a fleet of mini nuclear reactors to generate the power needed for the rise in use of artificial intelligence. The US tech corporation has ordered six or seven small nuclear reactors (SMRs) from California’s Kairos Power, with the first due to be completed by 2030 and the remainder by 2035.

Event will push for greater transparency and aims to rank AI firms in terms of ability to meet climate goals World leaders at the next AI summit will focus on the impact on the environment and jobs, including the possibility of ranking the greenest AI companies, it has been announced. Rating artificial intelligence companies in terms of their ecological impact is among the proposals under consideration, while other areas being looked at include the effect on the labour market, giving all countries access to the technology, and bringing more states under the wing of global AI governance initiatives.

Many fear the arrival of tech giants such as Amazon, Microsoft and Google in the state of Querétaro will place too much of a strain on scarce water and electricity resources In a nondescript building in an industrial park in central Mexico, cavernous rooms hold stack after stack of servers studded with blue lights, humming with computations and cooled by thousands of little fans and large vents blasting great columns of air across the room. “Datacentres are the lungs of digital life,” says Amet Novillo, the managing director of Equinix Mexico, a digital infrastructure company, as he stands in the middle of the airflows that stop the hardware overheating.

Nordic country, paradoxically a major oil producer, has set target for all new cars sold to be zero emission Electric cars now outnumber petrol cars in Norway for the first time, an industry organisation has said, a world first that puts the country on track towards taking fossil fuel vehicles off the road. Of the 2.8m private cars registered in the Nordic country, 754,303 are all-electric, against 753,905 that run on petrol, the Norwegian road federation (OFV) said in a statement. Continue reading...

Emissions from in-house data centers of Google, Microsoft, Meta and Apple may be 7.62 times higher than official tally Big tech has made some big claims about greenhouse gas emissions in recent years. But as the rise of artificial intelligence creates ever bigger energy demands, it’s getting hard for the industry to hide the true costs of the data centers powering the tech revolution. According to a Guardian analysis, from 2020 to 2022 the real emissions from the “in-house” or company-owned data centers of Google, Microsoft, Meta and Apple are likely about 662% – or 7.62 times – higher than officially reported.

Elon Musk turning you off Tesla? Here are 10 of the best electric cars, driven and chosen by our expert • How to buy an electric car – a guide Elon Musk is never far from a headline these days, from his recent inflammatory posts about the far-right riots in the UK to his endorsement of Donald Trump for president. But his increasingly toxic rhetoric is having a knock-on effect: some Tesla owners are starting to rethink whether they should own his electric cars any more. Sales fell in July for the second straight quarter. It’s a shame, because Tesla makes great electric cars. I’d rate the latest Model 3 as one of the best around. It drives nicely, is built well (a previous Tesla foible), is efficient and Tesla sells it at a price that makes other EV makers do a cartoon double-take. But if you’re committed to electric cars, and Musk is turning you off Tesla, there are plenty of other good options. Established carmakers and newcomers have caught up with and, in many cases, overtaken Tesla with their electric offerings. Here are the 10 best non-Tesla EVs you can buy now; I’ve driven them all except the Renault 5, which is expected to arrive in the UK in the first quarter of 2025. Continue reading...

As multinationals and researchers harvest rare organisms around the world, anger is rising in the global south over the unpaid use of lucrative genetic codes found on their land Even in the warm summer sun, the stagnant puddles and harsh rock faces of Ribblehead quarry in North Yorkshire feel like an unlikely frontier of the AI industrial revolution. Standing next to a waterfall that bursts out from the fractured rock, Bupe Mwambingu reaches into the green sludge behind the cascade and emerges with fistful of algae. Balancing precariously on the rocks, the researcher passes the dripping mass to her colleague Emma Bolton, who notes their GPS coordinates and the acidity, temperature and light exposure on a phone app. Continue reading...

A secondhand EV is a possibility for many families as the cost of desirable models, including Kias and Teslas, falls to £15,000 If your current car is on the way out and you think an electric replacement is too expensive, think again. Three-year-old Tesla Model 3s and Kia e-Niros that will do 250-300 miles on a single charge can now be bought for as little as £14,000. In the last year, forecourt prices for used electric cars have tumbled to the extent that previously unaffordable models are now within the reach of many families for the first time.
