This article aims to study the regional development of renewable energies (RE) in France over the period 1990–2015. As a first step, Principal Component Analysis was used on the collected data, which led to a classification of RE's development into four sub-periods. The first two sub-periods (1990–1994) and (1995–2003) are characterized by a strong dependence on hydro, thermal, and fossil energies. The third sub-period (2004–2011) shows the development of new RE sources. In the last sub-period (2012–2015), RE's use in transport and heating sectors has grown significantly. In a second step, we carried out a Hierarchical Ascendant Classification (HAC) on each sub-period to highlight the similarities and differences between regions in terms of diversification of the energy mix. The results show that 16 regions followed a similar path over the 1990–2015 period because of an initial favorable condition for sharing RE consumptions. Other regions (Auvergne, Aquitaine, Burgundy, Franche-Comté, Poitou Charentes, and Lorraine) experienced more contrasting trajectories in their RE development.

本文旨在研究1990年至2015年法国在可再生能源方面的区域发展。第一步，对收集的数据进行主成分分析，从而将可再生能源的发展分为四个子时期。前两个子时期（1990-1994年）和（1995-2003年）的特征是强烈依赖水能，热能和化石能源。第三子时段（2004-2011年）显示了新的可再生能源的发展。在最后一个子时期（2012-2015年），可再生能源在运输和供热行业的使用显着增长。第二步，我们在每个子周期上进行了层次上升分类（HAC），以突出地区之间在能源组合多样化方面的异同。结果表明，在1990-2015年期间，有16个地区遵循了类似的路径，这是因为共享可再生能源消费的最初有利条件。其他地区（奥弗涅，阿基坦，勃艮第，弗朗什-孔泰，普瓦图夏朗德和洛林）在可再生能源发展中经历了截然不同的轨迹。
