摘要
Accelerating the deployment of renewable energy renewable energy (RE) is one of the most important strategies to achieve the 2060 carbon neutrality goal in China. In this context, it is crucial to understand the RE investment needs at the provincial level to better allocate resources and develop policies to facilitate RE development and deployment at the local level. In this paper, we estimate the wind and solar investment needs by Chinese provinces between 2020 and 2060 under four alternative pathways towards China’s 2060 carbon neutrality, by using a global integrated assessment model with provincial details of China combined with the most updated cost data for each province, and explicitly considering national and local investment market conditions. Results show that the average annual wind and solar investment needs are $317 billion per year between 2020 and 2060, or 2.3 percent of China’s 2020 GDP. We find large spatial and temporal variations of the needed RE investment and identify that technologies, resource endowment, and financial conditions are the three primary contributions to the regional disparity in investment needs. Our findings explore distributional and inequality implications and associated needs required to achieve a harmonious development pathway that meets diverse needs.
