When you picture the tech industry, you probably think of things that don’t exist in physical space, such as the apps and internet browser on your phone. But the infrastructure required to store all this information – the physical datacentres housed in business parks and city outskirts – consume massive amounts of energy. Despite its name, the infrastructure used by the “cloud” accounts for more global greenhouse emissions than commercial flights. In 2018, for instance, the 5bn YouTube hits for the viral song Despacito used the same amount of energy it would take to heat 40,000 US homes annually.
This is a hugely environmentally destructive side to the tech industry. While it has played a big role in reaching net zero, giving us smart meters and efficient solar, it’s critical that we turn the spotlight on its environmental footprint. Large language models such as ChatGPT are some of the most energy-guzzling technologies of all. Research suggests, for instance, that about 700,000 litres of water could have been used to cool the machines that trained ChatGPT-3 at Microsoft’s data facilities. It is hardly news that the tech bubble’s self-glorification has obscured the uglier sides of this industry, from its proclivity for tax avoidance to its invasion of privacy and exploitation of our attention span. The industry’s environmental impact is a key issue, yet the companies that produce such models have stayed remarkably quiet about the amount of energy they consume – probably because they don’t want to spark our concern.
If we don’t develop practical nuclear fusion before our fossil inheritance effectively runs out we sure will. It will also go down following ecological collapse caused by using all that energy. Infinite energy doesn’t make up for a collapsed ecosystem.
Just to add: Even if we can replace the energy from diminishing fossils with nuclear etc, there are still a huge forest/mountain of essential technology and products that are reliant on fossils, and they won’t be replaced by anything. I can recommend Nate Hagens on YT for more on the ‘energy blindness’ issue, and what it means for our civilization to lose the last.
Nate is amazing, he and some of his guests are exactly who I learned this from.
True enough.
Fusion would be better, but the fission tech we have is already enough to fix the energy problem.
Why not fission?
To some degree, fission also, though it has a few other problems like safety and security concerns around nuclear materials, locations of fuels and whether they are in friendly nations, other things the fuels can be used for and all the politics that goes with that, etc.
But we need more than just energy. At some point, regardless of our energy, we are going to destroy Earth’s ecosystems using up other resources, using this energy to mine unsustainably, etc. More energy just means we kill ourselves faster. We should not be looking for more or cleaner energy with which to kill ourselves with, we should be looking to continuity of our species and that requires living sustainably within the bounds of our environment.
