The study of regional development of renewable energies in France between 1990-2015 reveals four distinct sub-periods with differing patterns of RE consumption. While 16 regions followed a similar development path, other regions showed contrasting trajectories in their RE development over the years.
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-Comte ', Poitou Charentes, and Lorraine) experienced more contrasting trajectories in their RE development.
