Morgan Stanley estimates that data centres are currently using 5 per cent (1,050 MW) of the electricity on Australia’s power grid and that is expected to grow to 8 per cent (2,500 MW) by 2030.
Some estimates even suggest they could require up to 15 per cent of the power on the grid by then.
I think they are more efficient than years ago yes, but some chips are consuming more power overall too. Yes what took up 40u a while ago can now fit in 10u but data centers aren’t reducing in size, they’ll just fill that 40 with more hardware
They need to fill that 40RU with more hardware to keep up with ever growing data creation demand. Think how much data your home produced a decade ago compared to now. Everything has some sort of sensor inside now recording data.
