Conclusion: CIOs and IT operations managers must avoid the risk of succumbing to green fatigue. Greenwashing is rampant, with every IT vendor promoting its products as "green." Most IT publications have at least one Green IT focused section. At the same time organisations are continuing their focus on cost reduction, often with IT under the magnifying glass. In these circumstances, it is easy for Green IT to be given lip service only while everybody gets on with the "real work". This must not happen. The biggest green issue for IT is how to reduce the energy consumption of the data centre. Organisations should first focus on reducing the energy consumption in their data centre: not only does it bring a significant green benefit but it saves money.
