为实现建设资源节约型和环境友好型社会的目标,促进国民经济可持续发展,我国已将节能降耗作为国家经济建设的基本国策之一,并明确“十二五”期间单位GDP能耗要降低16%,单位GDP二氧化碳排放要降低17%。信息技术(IT)领域在节能减排方面担当着重要的角色,不仅IT领域本身需要节能降耗,而且要通过IT技术帮助传统产业实现节能降耗。 In order to achieve the goal of building a resource-saving and environment-friendly society and promoting the sustainable development of the national economy, China has taken energy conservation and consumption reduction as one of the basic national policies for the country’s economic construction. It has also clarified that during the “12th Five-Year Plan” period, 16% lower consumption, carbon dioxide emissions per unit of GDP should be reduced by 17%. The information technology (IT) area plays an important role in energy saving and emission reduction. Not only the IT sector itself needs energy saving, but also the IT industry should help the traditional industries to save energy and reduce consumption.
