Based on the development history of energy geography and its energy transition, this article proposes some ideas for the development of new energy geography from the perspective of geography. Firstly, the definition of new energy geography is provided. Continuing the disciplinary connotation of traditional energy geography, it is defined as the applied geography that studies the spatial and temporal characteristics, exploitation potential and influencing factors, process and pattern of production and consumption, and socio-economic and ecological effects of new energy resources such as wind and photovoltaics. Secondly, the scientific logic of constructing new energy geography is elaborated. We believe that, compared with traditional fossil energy, factors affecting wind and photovoltaic resources and their development and utilization have a high degree of spatiotemporal heterogeneity due to the influence of atmospheric circulation, solar radiation, and underlying surface processes, making them the most geographically characteristic research objects. Thirdly, key geographical characteristics of new energy including scale dependence and regional differentiation are proposed. Scale dependence is reflected in the multi-scale spatiotemporal variation of wind and solar resources, the feedback effects between atmospheric processes at different scales and wind farms, as well as the scale effects on the degree and scope of impacts on ecological environment, economic viability, and social acceptance. As physical entities, new energy infrastructure is always situated in specific geographical environments, exhibiting significant regional differentiation characteristics in terms of the climate and ecological effects of its production and operation under the constraints of atmospheric processes. On this basis, some priority research topics under the framework of new energy geography are proposed, including the underpinning land surface processes mechanism forming the spatiotemporal distribution of wind and solar energy, the geographical spatial characteristics of wind and solar energy production and consumption, the impact of the resilience and robustness of new energy supply on socio-economic systems, the impact of future climate change on new energy systems, the climate effects of large-scale new energy construction, the ecological environment and health effects of new energy construction, and the perception of new energy landscapes and cultures. Finally, the technologies and methods of new energy geography research, including geospatial inversion, climate model analysis, energy simulation, ecological environment response analysis, multi-scale dynamic simulation and artificial intelligence technology, are proposed.
