Hewlett-Packard announced that a new data center in Bangalore, India, has achieved energy savings of up to 40 percent due to the use of 7,500 sensors and software to constantly make temperature corrections based on cooling needs, Mercury news reports.

The company says its data-center cooling technology at that facility will save it 700,000 gallons of diesel fuel a year. That’s the equivalent of 7,500 megawatt-hours of power a year, about the energy consumption of 750 U.S. homes, and represents a 7,500-ton reduction of carbon dioxide emissions, the company said.

The HP process, known as Dynamic Smart Cooling, is being tested in a 70,000-square-foot data center, with a mix of older equipment and newer server racks and blades. Previously, HP data centers were spread over 14 facilities in Bangalore.
