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 CO

emission?
Many everyday tasks take a surprising toll on the environment. A Google search can leak between 0.2 and 0.7 grams of CO
2
, depending on how many attempts are needed to get the right answer. To deliver results to its users quickly, then Google has to maintain vast data centers around the world, packed with powerful computers. While producing large quantities of CO
2
, these computers emit a great deal of heat, so the centers 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.
选项
答案
从全球范围来看,IT行业产生的温室气体大约占二氧化碳总排放量的2%,这跟全世界所有航空公司产生温室气体一样多,谁会想到这一点呢? 许多日常的工作对环境造成了人们意想不到的破坏。因搜索正确答案所需搜索次数多少的不同,一次谷歌搜索会产生0.2到0.7克的二氧化碳。为了快速给用户提供搜索结果,谷歌在世界各地建立大型数据中心,这些数据中心挤满了大功率计算机。计算机在排放出大量二氧化碳的同时,会产生大量的热量,因此数据中心又需要良好的空调系统,这甚至会消耗更多的能量。 然而,谷歌和其他大型技术提供商在严密监控其能效并不断进行改进。监控只迈出了减排的第一步,但减排还需要采取更多的措施,仅仅依靠大公司是不够的。
