Due to their growing power demand, data centres can set a precedent for how to handle rapid load growth in a way that supports the grid and ensures reliable, resilient, carbon-free electricity. In other words, they can set the template for the coming surges in demand from EVs, buildings electrification, and the new rich-world policies of onshoring industry and manufacturing, explain Alexandra Gorin, Roberto Zanchi and Mark Dyson at RMI. Big, … [Read more...]
Big Data’s huge power demand can migrate globally, instantaneously: implications for planning regional capacity and markets
Something is going to make the planning of regional power generation and associated markets even harder: the ability of big data users to shift their demand across the globe quickly, based on price. Ira Joseph at CGEP peers into the near future to ask some difficult questions. When such power demand can “at the push of a button” migrate long distances, how do you make predictions for local capacity needs? And today, market design in most … [Read more...]
Will AI queries increase Data Centre energy use by an order of magnitude?
Data centres globally consumed 220-330 TWh in 2021 (California uses around 278 TWh/year). How much more will they consume if AI takes off, given AI queries consume an order of magnitude more energy, and there are over 5bn internet users worldwide? The first step is to make a decent evidence-based prediction, but the U.S. and the EU are only expected to enforce reporting requirements next year, explains Meredith Fowlie at UC Berkeley’s Energy … [Read more...]
Simple superconducting diode can dramatically cut energy use in transistors, data centres
Some estimates say data centres could be consuming up to 20% of all power globally in ten years. That’s largely because the billions of transistors have to be cooled. Elizabeth Thomson at MIT describes breakthrough research that has made a superconducting diode that’s twice as efficient as the standard, therefore generating and wasting far less heat. What’s surprising is that some straightforward physics of materials was utilised, in contrast to … [Read more...]
The nexus between data centres, efficiency and renewables: a role model for the energy transition
How much will electricity consumption from data centres grow from today’s 1% of the global total? 40-fold by 2030? Or a more manageable 5-fold? Or less? Sean Ratka and Francisco Boshell at IRENA try to answer this question by looking at the innovations being made by the tech industry to drive down power costs and emissions. The evidence is promising. Though data centre computing output jumped 6- fold between 2010 and 2018, their energy … [Read more...]
