The research relates to the ongoing discourse about energy transition, starting from the consideration that the energy transition generates a landscape transition too, thanks to the long-lasting relationship between energy development and spatial organization, the first one having inevitably an impact on the second. The period we are living, it is not an exception. The ongoing transition, which implies a gradual relocation and territorialisation of the energy system, need planning and design landscape according to reduction of energy consumption and renewable energy production goals. In this framework the main goal of this research is to establish and assess energy conscious landscape planning and design in the context of the ongoing energy transition.The research framework is based on different concepts: urban metabolism, circular economy and cradle-to-cradle. Through a critical view of the linear functioning ‘take-make-waste’ of our society, they could inform choices and strategies aiming a better energetic sustainability, with impacts on spatial and landscape planning and design.A comparison between France and the Netherlands, nations engaged in energy transition process and with an important and long lasting tradition in landscape architecture, but with differences, contributes to understand how landscape and spatial planning and design are taken into account and which energy development strategies and synergies are developed. The research analyses territories: two in France and one in the Netherlands, committed to a transition process. The contribution of landscape architects is also investigated. The similarities and differences found in the two national contexts allow to put the analysis into perspective.Results show that in French territories there is a general lack of recognition of landscape planning and design as able to contribute to energy transition, beyond the integration of renewable energy technologies. On the contrary, this role seems to be better addressed in the Dutch context. Nevertheless, ...
