#AI#BigTech#Energy#GenerativeAI: "One problem is that data centres tend to consume power at a steady rate, including when the sun is not shining nor the wind blowing. So technology firms are also thinking of ways to make data-processing more flexible. In March Sidewalk Infrastructure Partners, an investment fund co-created by Alphabet, presented a detailed plan for how this could be achieved. It involves a combination of microgrids (which can run independently but also exchange energy with others nearby), batteries and advanced software in order to enable shifting less time-sensitive tasks, such as training ai models, to periods of fallow demand. Jonathan Winer, one of Sidewalk’s founders, expects such data centres to pop up first in energy-constrained places like Arizona, California and Massachusetts.
Renewables are not the only area of big tech’s power interest. In March aws paid $650m for a 960-megawatt (mw) data centre in Pennsylvania powered by a nuclear reactor located next door. Microsoft has struck a deal with Constellation Energy, America’s biggest nuclear operator, for supply of nuclear power for its data centre in Virginia, as a backstop when wind and solar are unavailable. Both firms have also been looking at “small modular reactors”, a promising though unproven nuclear technology."
