Private electricity producers, for example, will not invest in large-scale renewable energy generation if the government does not have long-term climate and energy policies or plans for spurring construction of long-distance transmission lines to carry new low-carbon energy sources to population centers. Such messy policy details have never much bothered free-market economists.
比如，如果政府不拿出长期气候和能源政策或刺激建设长距离输电线从而将低碳能源资源引向人口中心的计划，私人发电商就不会投资于大规模可再生能源发电。混乱的政策细节令自由市场经济学家困扰不堪。
