Personal bias can be overcome with large, balanced author teams, but in the case of thereport on renewables it is not obvious there was such a balance. The report discusses thedownsides of various renewable energies, the challenge of incorporating them into existinginfrastructure at scale and the vast if poorly bounded costs of deploying them: $1.5 trillion to$7.2 trillion in the 2020s, depending on the scenario. But the summary, in particular, is largelyupbeat.
个人偏见可以在很大程度上被均衡的作者团队所解决,不过在报道可再生能源方面,却很少能够看到这样的均衡。该报告讨论了各种可再生能源的缺点,在现在基础设施上大量使用它们所面临的挑战,以及整合不好这些能源时所付出的代价:按照此纲要,在21世纪20年代需要投入1.5万亿到7.2万亿美元。但该报告的摘要在很大程度上还是持乐观态度。
A case in point is the generating capacity ofrenewables. The report discusses the fact that this issmaller than for other forms of power generation.But the summary glosses over the problem, forinstance by not mentioning that, althoughrenewables have accounted for almost half theworlds new generating capacity in the past twoyears, the other half has probably generated a lotmore electricity.
在这一点上,典型的例子便是可再生能源的发电量。该报告讨论了可再生能源比其他形式的能源发电规模小的事实。不过摘要掩饰了问题,例如,虽然可再生能源在过去的两年间,占到了全球新增发电量的一半,但另一半可能已经产生了更多的电量,报告却并没有提到这些。
