What: “IBM has saved $50 million in the past two years through thousands of energy and efficiency projects around the world, the company says.
IBM’s energy conservation program, which now involves more than 3,000 projects, has since 1990 avoided almost $400 million in energy expenses and 5.4 million megawatt hours of energy.”
Why: “IBM is aiming to eliminate 1.1. million megawatt hours (MWh) of energy use by 2012, a goal set in 2009. By the end of last year, IBM exceeded its interim goal of cutting out 496,000 MWh by eliminating 523,000 MWh.”
How: “Efficient lighting, better operating schedules for building systems and cloud computing are among the efforts that pushed IBM over a couple of its energy goals.
Outside of building controls, IBM also undertook data center projects to use less energy, less equipment and monitor facilities better. Turning more to cloud computing, IBM deployed 55 servers with cloud software, which would have equalled 488 physical servers, saving $1.3 million.
IBM has also been using technology developed by its IBM Research arm that shows heat sinks and cooling leaks in data centers with real-time, 3D images. The company also continues to use analytics software to manage energy use in data centers.”
