There are a lot of ways to decrease energy consumption in the data center; everything from building hot/cold aisle containment systems, to distributing higher voltages at the rack, to eliminating voltage step-downs, to building a brand new facility in a Scandinavian country and using airside economizers to cool equipment. The obvious downside with any of these is that they may require a big overhaul of your existing infrastructure, disrupt operations, or be too costly to undertake.
Switched PDUs are a lower cost solution that can easily fit into an existing infrastructure or be a part of a new data center build. Most importantly, they tackle several issues in one shot.
