Companies are investing big in IT, but it's not necessarily paying off in environmental dividends, according to a new survey of IT professionals around the world.

The Green IT Benchmark report, sponsored by Fujitsu, looked at how enterprises in Australia, India, the U.K. and the U.S. are faring on five different categories of green IT. Perhaps not surprisingly, the data center and internal IT operations are the recipient of most IT departments' time and energy, while applying IT to the measurement, management and reduction of a company's overall carbon footprint is still a rare occurrence.

That fact is illustrated by last week's Power IT Down Day, which aimed to get IT managers and employees to turn off their PCs and peripherals before heading home for the weekend. While over 17,000 people signed up to participate -- the biggest turnout yet -- that's still a minuscule fraction of the population. Fortunately, powering IT down is an energy-saver year round.
