Renewable energy sources as a catalyst for energy transition: Technological innovations and an example of the energy transition in France.

The present article sets out to examine the connection between energy transition and factors associated with renewable energy sources, buildings and other sectors, placing emphasis on France. The methodology includes: Collection of scholarly writings, classification, identification of research questions, bibliographic analysis, identification of important findings, discussion. The results of a study (EDF, Le nucléaire en chiffres) demonstrated that, in 2019, around 80% of the electricity production from nuclear energy (in France) was provided by 4 regions: Auvergne-Rhône-Alpes , Grand Est , Centre-Val de Loire , Normandie. France has a high dependence on nuclear power generation and, for this reason, renewable-energy penetration is an imperative part of the French energy transition. Numerous studies show that energy transition requires actions based on burgeoning and avant-garde technologies, and effective policies. Moreover, energy transition poses challenges: decisions on nuclear power plants, sustainable development of small-island economies, etc. A discussion on the energy transition in Corsica (France) is also provided. Regarding the French overseas territories Corse (Corsica), Guadeloupe , Martinique , Guyane , Mayotte , Réunion , the findings of a study (Rakotoson and Praene, 2017) demonstrate that thanks to renewable energy sources/network interconnection, Corsica and French Guiana have lower emissions in comparison to the other territories: 0.505 and 0.373 kg CO 2.eq /kWh e , respectively. • The role of renewable energy sources in energy transition has been analysed. • Factors related to buildings, industry, etc. have been discussed (emphasis: France). • France, 2019.→ ≈ 80 % of the nuclear electricity generation was provided by 4 regions • There are challenges such as energy storage and decisions on nuclear plants. • Corsica and French Guiana: emissions 0.505 and 0.373 kg CO 2.eq /kWh e , respectively.
