The PUE metric is often criticized as being an overly simplistic measure of data center energy efficiency. Nevertheless, regulators seeking to control runaway data center energy use are finding it increasingly useful.

Many countries have now set PUE limits or targets for newly planned data centers, and some have started to apply (looser) limits to existing facilities (see Table 1). In a few cases, mandatory maximum PUEs are below the region's average or best-practice levels, so compliance by those operators with existing data centers will likely require significant investment.
