Firms must improve their energy efficiency or face severe financial consequences, according to analyst Gartner. IT systems, in particular servers, are increasingly power hungry as technology capabilities increase, but this comes at a time when power supplies are more strained and less predictable. Some data centres use as much energy as a small town, which is significant from both financial and environmental perspectives, says the Carbon Trust.
David Roberts, chief executive of user group the Corporate IT Forum, says the IT sector needs to accept responsibility for its high energy consumption. 'The cost of energy and the demand for energy to run computers is colossal and growing. As computers become more pervasive we will only need more power rather than less,' he said. 'It would be inappropriate to pretend that the IT community is not consuming more than its fair share of electricity.'
