All of the monstrous data centers popping up globally are having multiple negative impacts on the planet, the EPA notes.\nFirst, there is the obvious effect, power consumption. Data centers account for 3 percent of the global electricity supply and consume more power than the entire United Kingdom.\nBut beyond that is the waste caused by disposal. With Amazon and the like deploying more than a million physical servers per year globally, the old server equipment they replace have to go somewhere. The same goes for your old servers.\n\nE-waste 70 percent of toxic waste\nThe EPA estimates e-waste, disposed electronics, now accounts for 2 percent of all solid waste and 70 percent of toxic waste, thanks to the use of chemicals such as lead, mercury, cadmium and beryllium, as well as hazardous chemicals such as brominated flame retardants. A lot of that is old servers and components.\nAnd much of that is due to poor configuration and management, according to a study from server vendor Supermicro. In a survey of people who purchase and administer data-center hardware (pdf), only 59 percent of the 361 respondents consider energy efficiency important when building or leasing a new data center. It's fourth on the priorities list behind security, performance, and connectivity when managing existing data centers.\nThe result? About 58 percent of respondents did not know their data-center Power Usage Effectiveness (PUE). PUE measures how efficiently you cool your systems. The closer to 1.0 the better. And while PUE is an obsession for Google and other hyperscale data center operators, it hasn\u2019t caught on with the masses.\nFor example, it\u2019s been found that you don\u2019t necessarily have to chill your data center equipment to that of a refrigerator. Natural ambient temperature is fine in many cases, and you can save a lot of money, power, and water if you don\u2019t turn your data center into a meat locker. It may not be pleasant for the humans, but the servers do just fine.\nFew people look at the efficiency of their data centers\nHowever, only 6 percent of those who did know their PUE have it at optimal levels. In short, hardly anyone is looking at the efficiency of their data center, and that is translating into burned out hardware that needs to be disposed. An estimated 20 to 50 million metric tons of e-waste is disposed of globally every year, depositing heavy metals and other hazardous waste into our landfills.\n"Only 28 percent of respondents consider environmental issues in the selection of data center technology. Supermicro challenges them to look more broadly at their strategy and start measuring their data center efficiency with a new metric \u2014 the Total Cost to the Environment," the report states.\n"Supermicro urges industry leaders to incorporate disaggregated resource-saving solutions into their data center plans, with a goal to lower the average data center PUE to 1.30 and reduce their e-waste by 2025. The health of our environment, our planet, and our citizens may depend on it."\nMore and more companies are adopting green policies and an overall mindfulness of their environmental impact. You can start by better managing your data center.
