Data centers and servers take up an increasingly large slice of the average company's electricity expenses. But HP has an idea on how to make those data centers more efficient.

Their new technology is called HP Dynamic Power Capping. Essentially, it lets IT managers decide the upper amount of energy specific servers will use, and "cap" that server at a lower energy level than it might otherwise demand.

HP says this more efficient energy management can result in savings of 25%.

Dynamic Power Capping had already been preloaded on many HP servers, but this is the first time that it is available on its own, as an add-on to any existing physical or virtual server. License fees range from $399 to $549 -- not too bad for what could amount to a substantial power savings.
