It’s only a few weeks since the United Nations summit on climate change in Durban at the back end of last year and I came across this story.
The piece argues that IT managers can save money and reduce their carbon footprint by increasing the temperature in their data centres.
Intel, for example, is reportedly advising its customers to increase the temperature in data centres, arguing that companies can actually save four percent in energy costs for every one degree in centigrade they turn up the heat.
That is because most data centres in Europe run at a temperature of between 19 and 21 degrees centigrade to avoid creating hot spots that might cause equipment to malfunction. The cooling equipment required to maintain that temperature costs around $27 billion a year to run and consumes 1.5 percent of total world power, according to Intel.
Many companies worldwide are now looking at increasing the temperature of their data centres up to 27ºC (80.6ºF), in a move that could help them save costs and reduce their carbon footprint. Facebook has saved over $200,000 a year in energy bills by reprogramming its cooling to run at 81ºF. Microsoft too has saved $250,000 a year by increasing the temperature by just 2-4ºC.
Interesting story – I think there is more to come on this as the year develops though I’d venture to suggest that rightly or wrongly, in today’s austere times, the driver is more likely to be saving costs than reducing the carbon footprint i.e. talk green, mean lean.
