The Download: Tweaking AI for energy efficiency, and China’s leaked data

Plus: The Large Hadron Collider has helped scientists to discover three never-before-seen particles

This is today's edition of The Download, our weekday newsletter that provides a daily dose of what's going on in the world of technology.

These simple changes can make AI research much more energy efficient

What’s the news?: Deep learning is behind machine learning’s most high-profile successes. But this incredible performance comes at a cost: training deep-learning models requires huge amounts of energy. Now, new research shows how scientists who use cloud platforms to train algorithms can dramatically reduce the energy they use, and therefore the emissions they create.

How can they do it?: Simple changes to cloud settings are the key. Researchers created a tool that measures the electricity usage of any machine-learning program that runs on Azure, Microsoft’s cloud service, during every phase of their project. They estimated emissions based on the zip codes of servers running 11 machine-learning models, finding that they can be significantly reduced if researchers adjusted settings to use servers in specific geographic locations and at certain times of day.

The bigger picture: Getting people to opt in to adjust their own settings is an uphill battle. Only 13% of Azure users running machine-learning programs have looked at the energy measurement tool since it debuted in October, so the next step will be convincing the rest of them.

The world will need dozens of breakthrough climate technologies in the next decade

We’re living in a pivotal decade. By 2030, global emissions must fall by half, mostly through massive deployment of existing technologies like wind turbines, solar panels, and electric vehicles. But emerging climate technologies must come to market during this decade too, even if they don’t make much of a dent in emissions right away.

Those on this year’s list of MIT Technology Review Innovators under 35 list are seizing the chance to decarbonize the economy and to make the clean energy transition affordable. Read more about their work and what’s needed to help them to succeed in this essay by Varun Sivaram, the senior director for clean energy and innovation for US special presidential envoy for climate John Kerry.

This essay is part of MIT Technology Review’s 2022 Innovators Under 35 package recognizing the most promising young people working in technology today. See the full list here.

The big story

A plan to redesign the internet could make apps that no one controls

July 2020

Back in the early days of the accessible internet, many of its pioneers championed a free and open internet controlled by its users. Fast-forward a quarter-century and that vision feels naïve.

It’s clear that a desire for revolution is brewing, led in part by Dfinity, a non-profit building what it calls the internet computer, a decentralized technology spread across a network of independent data centers that allows software to run anywhere on the internet rather than in server farms that are increasingly controlled by large firms.

But this desire for a rewilding of the internet is not about nostalgia—the dominance of these companies, and the ad-tech industry that supports them, has distorted the way we communicate—pulling public discourse into a gravity well of hate speech and misinformation—and upended basic norms of privacy.
