[1]I was shocked to learn recently that some scientists want to scale back their research in an effort to decrease carbon emissions. The crisis is here, they said, and we need to cut back on our energy-intensive modelling. At the very least, we need to make our energy use far more sustainable.
[2]It is unarguable that our laboratories, scientific instruments, rockets and satellites - the tools we scientists need to measure the planet's pulse - demand significant amounts of energy both in their construction and operation. And it is equally true that science's unrelenting appetite for information has caused a mushrooming of energy-intensive data centres around the world. According to the International Energy Agency, these buildings now consume about 1 percent of the world's electricity.
[3]If the world is to meet its net-zero ambitions, we must think hard about how we can deliver sustainable computing and deliver more LUMIS.
[4]Every day, scientists, technologists and engineers are discovering new ways to exploit renewable energy sources and develop techniques not just to use power more intelligently but to power our intelligence. A great example of this is Europe's largest super computer, LUMI in Finland, which is astonishingly carbon- negative, established in an old paper mill, it is powered by a nearby river and its remote heat warms the people who live in the surrounding town of Kajaani
