One suggestion is for greater integration of energy systems, which would see data centers located adjacent to energy industries or having data centers integrated with hydrogen-generating plants and fuel cells. This solution sidesteps planning problems by locating data centers alongside low-carbon energy industries. A major issue with this (aside from the available land) is blurring the lines between the data center operators, utility providers, and energy companies.
This flips the assumptions of what a datacentre looks like, if the power density keeps increasing, instead of a DC with on-site power, you might have a power with on-site DC
