The Economist writes about three technological fixes to reduce data centre power consumption:

The first is new multi-core processor chips, in which performance is improved not by increasing clock speed, but by building several processing engines, or cores, into each chipa far more energy-efficient approach.

The second fix comes from using more efficient power supplies. At the moment, data centres perform many conversions between alternating current (AC) and direct current (DC). This wastes energy, which is emitted as heat and increases the need for cooling. It would be far more efficient to power servers directly from a central DC supply.

The third fix is the more careful use of cooling systems. HP, for example, has devised a scheme called Dynamic Smart Cooling, which links temperature sensors installed on servers to air-conditioners so that blasts of cool air can be directed towards particular servers only when needed.
