The levels of energy efficiency found amongst computers offering the same levels of functionality can be highly divergent. With this factor in mind computers have been addressed by many environmental initiatives around the world ranging from voluntary eco-labels to mandatory regulations. It is shown that even the most successful and widely known of these initiatives have not been able to fully maximize the energy efficiency savings opportunities of computers due to the fast moving nature of the product group often increasing efficiencies quicker than initiatives can refresh specifications. Despite the fast moving nature of energy efficiency improvements in computers it is shown that significant savings opportunities are still available within the computer area. Some of these savings opportunities are described and advice on how they could be further exploited by environmental initiatives is given.
