The largest data center operators have made significant strides in slashing their water use, and the industry has developed metrics and best practices to encourage broader participation in the effort. The focus on data center water usage made headlines last week when Facebook released its initial data on water usage effectiveness (WUE) at its data center in Prineville, Oregon. Read More

Best Practices for a Green Data Center

Rising energy costs are at the forefront of most IT decisions, and impact operational expenditures considerably. Green initiatives vary widely in data centers and colocation providers. Having green initiatives is a start, but acting on them and having tangible results from them to demonstrate cost savings can often times be a different story. Embarking on a path to reduce costs and your carbon footprint starts with knowing the right questions to ask.

Wind-Powered Data Center Project On Hold


An oft-delayed project to build a major wind-powered data center is on hold again. Backers of WindData have scrapped plans to build a campus in a suburb of Austin that was to feature as many as five data centers. The Baryonyx Corp. says it is no longer considering a 50-acre site in Pflugerville that had been the focus of its development efforts over the past year. Read More

The Green Grid and Climate Savers Will Merge

Improved energy efficiency practices could cut server room energy waste by at least 40 percent, saving businesses and organizations over $3 billion annually, says NRDC.

The Green Grid, a global consortium focused on improving energy efficiency in data centers, announced today that the Climate Savers Computing Initiative will merge with The Green Grid, moving its programs and membership into The Green Grid brand. Read More

Greenpeace has issued a “regrading” of Apple’s data centers that gives the company Cs and Ds – as opposed to its earlier Ds and Fs. But the environmental group continues to use an estimate of Apple’s power use in its North Carolina data center that is four times higher than Apple’s numbers. Read More

eBay: Bloom Boxes Will Power Utah Data Center

The newest eBay data center project in Utah will run entirely on power generated by fuel cells from Bloom Energy, the company said this week. eBay will overhaul its power infrastructure to dramatically reduce its reliance on uninterruptible power supply (UPS) units and backup generators. Read More

Solar-Powered Micro Data Center at Rutgers


The Rutgers Computer Science Department has built a solar-powered “micro data center” comprised of a small container, a set of solar panels, and batteries. The Rutgers team is also developing GreenNebula, a customization of the OpenNebula cloud management software designed to eventually maximize renewable energy use by migrating virtual machines across green data centers.

HP Developing ‘Net-Zero’ Data Center Concept


Can existing energy strategies be tied together to create a “net zero” data center that requires no net energy from traditional power grids? HP Labs said this week that it is developing such a concept, which is being tested at a 3,000 square foot facility at the company’s campus in Palo Alto, Calif. Read More

Apple: iDataCenter Power Will Be 100% Green


Apple is doubling the size of its already-huge solar array at its data center in North Carolina, buying another 100 acres of land to house a second large installation of solar panels. The company said the expansion, along with its plan to use fuel cells from Bloom Energy, will allow it to supply 60 percent of the power requirements for its data center through on-site generation of renewable energy.
