I build the infrastructure that these data centers need to connect to the internet. Our projected power consumption is at least tripling from last year which was itself double the year before, and that’s only the power draw for the fiber optic infrastructure connecting these data centers together. They’re also building a ridiculous amount of computing power in those data centers which is another massive increase in power consumption.
There are some kind-of green efforts in progress to mitigate a bit of the environmental impacts of that increase in demand but most of what I have seen personally is just more draw from the local utility company. I have serious doubts about any data that indicates that tripling power consumption is not a major environmental problem.
