The generation of RES electricity in urban areas is regarded as a key element in achieving the 20% emission reduction target by 2020, in line with the strategy adopted by the European Union (EU). To understand the actual role of renewable energy planning in cities, as well as the adequacy of the strategies adopted, the authors considered statistics officially reported by the Joint Research Centre of the EU which regard the totality of submitted SEAPs and ten Sustainable Energy Action Plans (SEAPs) as sample cities. The double survey has a dual goal: one, the collection of overall statistics to have a general framework of all cities that submitted their SEAPs and to verify their inclusion of renewables, and two, the analysis of urban planning processes and climatic features through a sample of representative cities to try to determine direct connections between the implementation of renewables and real source potentials (an aspect not present in the JRC reports). Making comparisons between SEAPs submitted by European cities, the authors report in the final discussion the merits and drawbacks of the planning and usage of renewable sources in urban areas, thereby highlighting some relevant critical points and possible directions for future research efforts.

根据欧盟 (EU) 采取的战略，城市地区的可再生能源发电被视为到 2020 年实现 20% 减排目标的关键因素。为了了解可再生能源规划在城市中的实际作用，以及所采用战略的充分性，作者考虑了欧盟联合研究中心正式报告的统计数据，这些统计数据涉及提交的 SEAP 和十个可持续能源行动计划的总数（ SEAP）作为样本城市。双重调查有双重目标：一是收集总体统计数据，为所有提交 SEAP 的城市建立一个总体框架，并验证它们是否包含可再生能源，二是 通过代表性城市的样本对城市规划过程和气候特征进行分析，以试图确定可再生能源的实施与实际能源潜力之间的直接联系（JRC 报告中未出现的一个方面）。通过比较欧洲城市提交的 SEAP，作者在最后的讨论中报告了城市地区可再生能源规划和使用的优缺点，从而突出了一些相关的关键点和未来研究工作的可能方向。
