In a nutshell, they tell us that, while increasing energy efficiency is undoubtedly a good thing, it is most assuredly not a remedy for global warming. Or, as Saunders puts it, “energy efficiency may be a net positive in increasing economic productivity and growth, but should not be relied upon as a way to reduce energy consumption and thus greenhouse gas emissions.”
上述研究成果在气候政策领域的意义可谓是一言难尽。 简言之，研究成果告诉我们虽然提高能效毫无疑问是件好事，但可以肯定它不是解决全球变暖问题的方法。 或者就像桑德斯所说的那样，“能效在提高经济生产力和推动增长方面可能起到积极作用，但我们却不能靠它来降低能耗，进而降低温室气体排放。”
