Green computing is the study and practice of using computing resources efficiently. The primary objective of such a program is to account for[1] the bottom line, an expanded spectrum[2] of values and criteria[3] for measuring organizational (and societal) success. The goals are similar to green chemistry; reduce the use of hazardous[4] materials, maximize energy efficiency during the products lifetime, and promote recyclability[5] or biodegradability[6]of defunct[7] products and factory waste. [1] account for: v. 对…做出解释, 说明…的原因 [2] spectrum: n. 范围，系列，光谱 [3] criteria: n. 标准，尺度，准则 [4] hazardous: adj. 危险的 [5] recyclability: n. 再循环能力 [6] biodegradability: n. 生物降解能力 [7] defunct: adj. 无效 Modern IT systems rely upon a complicated mix of people, networks and hardware; as such, a green computing initiative must be systemic[1] in nature, and address increasingly sophisticated[2] problems. Elements of such as solution may comprise[3] items such as end user satisfaction, management restructuring, disposal of electronic waste, telecommuting, virtualization of server resources, energy use, thin client solutions, and return on investment (ROI[z1]?), etc.  [1] systemic: adj. 系统的 [2] sophisticated: adj. 复杂的 [3] comprise: v. 包含 [z1]Return On Investment，投资回报率，是指通过投资而应返回的价值，它涵盖了企业的获利目标。 As 21st century belongs to computers, gizmos[1] and electronic items, energy issues will get a serious ring in the coming days, as the public debate[2] on carbon emissions[z1]?, global warming[z2]? and climate change gets hotter. Taking into consideration the popular use of information technology industry, it has to lead a revolution of sorts by turning green in a manner no industry has ever done before. [1] gizmo: n. 小发明, 新东西 [2] debate: v. 辩论 [z1]carbon emissions,碳排放量，在生产、运输、使用及回收该产品时所产生的平均温室气体排放量。 [z2]全球气候变暖，指全球的平均气温逐渐升高的现象。由于温室气体对来自太阳辐射的可见光具有高度的透过性，而对地球反射出来的长波辐射具有高度的吸收性，能强烈吸收地面辐射中的红外线，也就是常说的“温室效应”，导致了全球气候变暖。 （1）Virtualization Computer virtualization[1] is the process
