The IT industry-backed Climate Savers Computing Initiative wants to double PC energy efficiency within three years.
Around half of the electricity used by desktop systems is wasted as heat. Servers are only slightly more efficient, wasting around a third of their electrical power.
The CSCI scheme, launched by Intel and Google today, aims to work with power supply manufacturers to improve efficiency to 65 per cent within a year, and continue developments until PCs make use of 90 per cent of the electricity they draw. The target for servers is 93 per cent.
