Microsoft’s energy management tool, Hohm, which launched this week, is a clear play to help consumers conserve energy. Log into the Hohm web site, enter your ZIP code and other details about your residence, and the service predicts your home energy use (or links to your historical energy use via your utility) and suggests ways to curb it. But Craig Mundie, Microsoft’s chief research and strategy officer, explained to us in an interview this week that Azure is expected to be more efficient than standard Web hosting and offer better power utilization, partly because the cloud takes advantage of on-demand scalable computing, growing and shrinking the amount of computing that’s applied to a particular task (and thus power used). In addition, the servers will feature efficient hardware designs and make better use of power management software, Mundie said.
We’ll forgive you if you thought Azure was just an outdated color in a Crayola box. Microsoft (MSFT) announced the cloud computing platform more than six months ago, and while few details are known about it, what is known is that it will be used by companies that want to deploy large Web services and host them in a cloud computing model. In the past, Microsoft would have allocated a couple of data centers to house Hohm, said Mundie. In that model, even if it were the middle of the night, the Web service would grind away in case there was a visitor. That meant it would be using more energy than needed. But with Azure’s setup, the servers are more like a car with different cylinders. “When they go uphill, we’ll turn them on, and when we’re coasting downhill, we’ll turn them off,” said Mundie.
However the networked computing world is tweaked, at the end of the day, it needs to more closely focus on using as little energy as possible. According to the Environmental Protection Agency, data centers currently consume 1.5% of total U.S. electricity, and that percentage is poised to more than double by 2011. In an increasingly broadband-connected world, in which a growing amount of our media, commerce, communications, and work life will be hosted in the cloud, energy conservation in IT will become extremely important. And who knows? Hohm’s legacy of being the first external Web service hosted on the energy-efficient Azure platform could stretch beyond its practical intentions to help reduce global energy consumption.
