全球变暖(全球平均气温上升)和我的电脑有什么关系?先别急,我们的意思不是说你电脑的散热片释放了多少热,而是你的电脑消耗了多少电能,因而排放了多少二氧化碳。电脑普及程度越来越高,全球对电脑依赖越来越强,电脑所消耗的电量越来越多,目前全球正在使用的个人电脑总量达到约8亿台,电脑已经成为电器中的耗电大户。在主要依赖火力发电的现实情况下,电量消耗的背后是温室气体二氧化碳的排放,加剧正在进行的温室效应,造成全球平均气温持续上升。从欧洲工业革命到现在,全球大气中二氧化碳浓度已增加了约30%,过去一个世纪以来,全球平均气温升高了约0.6℃。如果使用一台普通台式机,你每年将给大气“贡献”平均约100kg二氧化碳,如果你是中国人,那么将贡献120kg以上,我国约八成电量依靠火力发电获取。
What is the relationship between global warming (global average temperature rise) and my computer? Do not worry, we do not mean how much heat is released from your computer’s heat sink, but how much power your computer consumes and how much carbon dioxide. The popularity of computers is getting higher and higher. The global dependence on computers is getting stronger and stronger. The amount of power consumed by computers is increasing. At present, the total number of personal computers being used in the world reaches about 800 million. The power consumption of computers has become Big Under the reality of relying mainly on thermal power, the consumption of electricity behind the greenhouse gas carbon dioxide emissions, exacerbating the ongoing greenhouse effect, causing the global average temperature continued to rise. From the European Industrial Revolution to the present, the global atmospheric carbon dioxide concentration has increased by about 30% over the past century, the global average temperature increased by about 0.6 ℃. If you use an ordinary desktop, you will give about 100kg of carbon dioxide per year to the atmosphere, or 120kg if you are Chinese, and about 80% of our electricity is generated by thermal power.
