Currently, the entire energy consumption of servers stands about 2% of global electricity consumption, which itself is just one of the major emissions sources that include transportation and shipping, agriculture, residential heating etc. And 10% of that 2% is the insanity of cryptocoin mining, which by definition cannot be optimized since it's a system that ultimately competes on burning electricity: https://fortune.com/2019/09/18/internet-cloud-server-data-center-energy-consumption-renewable-coal/ https://fortune.com/2019/09/18/internet-cloud-server-data-ce... It could be 10% by 2030, based on projections made by experts in "sustainable ICT", which sounds self serving to me, and likely to ignore the massive energy demands of growing nations in other sectors.
