At a cost level, the capital costs of going green do have to be considered against the savings that will be made. However, the optimisation of energy usage is a major saving, particularly with the predicted upwards but not linear trend in prices. Also, less hardware will be required, leading to fewer software licences and to human resources being required – provided that everything is managed efficiently. Finally, the massive cost of a new data centre can be avoided – by going green, the reduced size of the consolidated hardware platform can extend the life of an existing facility by several years.
Although “Green” has slid down the list of priorities throughout the recession, it has not disappeared completely. The advent of government driven green initiatives, such as the CRC EES in the UK, means that several thousand UK organisations are now having to monitor and measure their energy usage at a granular level in order to plan to maximise the financial gains (or minimise the financial losses) through their positions in the CRC league tables, writes Clive Longbottom.
