Google announced this through a blog post on wednesday. For that, we started work to optimize the energy efficiency of our servers and later set out to build the most environmentally sustainable data centers possible. We now believe that Google-designed data centers are the most efficient in the world. It takes more energy to do a Google search on a personal computer than it does for Google to answer a query, said Hölzle.

Google has long pursued a build-it-yourself strategy to get the most out of its hardware and software. That’s why the company uses open source software, so it can customize the code it relies on and control its own destiny.About eight years ago, Teetzel said, Google began building its own servers, and because the person responsible also oversaw the facilities budget, that led to a focus on data center efficiency improvement and cost reduction.

Google claims that before the year’s end, two of its data centers will run entirely on recycled water. By 2010, the company expects that 80% of the total water it consumes will be recycled. The company also claims that it recycles or reuses 100% of its servers.Google isn’t going with complete disclosure and providing data center blueprints. “I don’t know if we’re going to outline a specific road map for everyone,” he said. “Doing what we would do wouldn’t work for the standard company.”

Google starts its energy push with designing better servers, which typically waste a third of the energy they consume before any of it reaches the components. The company uses highly efficient power supplies for the servers and efficient voltage regulators on the motherboards. It said it also strips out components that it doesn’t need, like graphics chips, and designs computers and server racks to use as little fan power as possible.But Teetzel believes that Google is providing enough technical information that other companies can make their operations more efficient and more competitive.
