一、原文
Who would have thought that, globally, the IT industry produces about the same volume of greenhouse gases as the world's airlines do—roughly 2 percent of all CO2 emissions?
Many everyday tasks take a surprising toll on the environment. A Google search can leak between 0.2 and 0.7 grams of CO2, depending on how many attemps are needed to get the "right" answer. To deliver results to its users quickly, then, Google has to maintain vast data centres aroud the world, packed with powerful computers. While producing large quantities of CO2, these computers emit a great deal of heat, so the centres need to be well air-conditioned, which uses even more energy.
However, Google and other big tech providers monitor their efficiency closely and make improvements. Monitoring is the first step on the road to reduction, but there is much more to be done, and not just by big companies.
二、参考译文
谁能想到信息技术行业产生的温室气体总量会与航空业不相上下,约占全球二氧化碳排放量的2%?
信息技术行业的许多日常工作对环境造成了意想不到的危害。每用谷歌搜索一次就会释放0.2克至7.0克二氧化碳,释放量的多少取决于使用者需要搜索多少次才能得到 “正确” 答案。然后,为了把搜索结果迅速传输给用户,谷歌不得不在全世界范围内维护大型数据中心,并配备大功率计算机。除了排放大量二氧化碳,这些计算机还释放很多热量,因此数据中心还需要良好的空调环境,而这又会消耗更多的能源。
不过,谷歌和其他大型技术供应商已在密切监控其数据中心的能效并做出改进。监控只是减排的第一步,需要做的还有很多,而且这不单单是大公司的事情。
