Data centers have outgrown their anonymity. They are large enough consumers of energy and space, that they have to enter the political landscape and justify their existence. But how do we know if a data really brings benefits to its location?

In some places (like London), it appears that they soak up grid connection capacity and block housing projects. In others (like Denmark and Ireland) they use renewable energy and jeopardize local decarbonization targets. 

It's not easy to know the net benefits brought by a data center, because much of what it does is in the virtual world, and is delivered to people far away. 

Max Schulze has some thoughts on how to start working out the real benefits of a data center - and we hope for more input from DCD readers and listeners.
