China has pledged to peak its carbon emissions before 2030 and achieve carbon neutrality before 2060. New energy decarbonization will be a major focus area for achieving the 'dual carbon' goals since it accounts for about 20 percent of China' s total energy consumption. The Xiong' an New Area' s geographical advantages and natural endowments have brought abundant wind and solar energy resources and have huge development potential in the field of new energy development. This paper summarizes the Xiong' an New Area' s resource endowment and achievements in developing new energy, and comprehensively analyzes the opportunities and challenges faced by this area in the process of building a national new energy demonstration zone in the context of achieving the 'dual carbon' goals. It sorts out the new energy development policy of the Xiong' an New Area and its history of new energy development and then points out that the current development of new energy in this area lies in power project construction, power grid construction, green energy consumption, energy storage development, and new energy equipment. This study believes that the Xiong' an New Area will experience three development stages of carbon neutrality: initial carbon neutrality, fluctuating carbon neutrality, and stable carbon neutrality, because this area has carried out green power planning simultaneously in the initial construction stage and has more green power supply. With the expansion of population and economic scale, the rapid increase in energy demand would lead to the decline in green power supply ratio, causing carbon neutrality to fluctuate and change over time. With the population and economic structure in a stable development stage, the proportion of high-value-added and high-tech industries would increase, and energy utilization technologies such as green electricity would make progress, resulting in the arrival of the stable carbon neutrality development stage. On the other hand, from the perspective of carbon sink potential corresponding to carbon sources, the planned proportion of the blue-green space and the construction land in the Xiong' an New Area would keep its carbon sink capacity in a relatively stable state for a long period of time. Therefore, in addition to the value-added of the natural carbon sink system, carbon capture, utilization and storage technologies and other means of artificial carbon sink can be used as adjustment tools under the carbon neutrality system.

As the world' s largest energy consumer and carbon emitter, China faces a serious situation in energy conservation and emission reduction. However, China' s digital economy is still developing rapidly. In order to explore how the development of the digital economy affects energy consumption and CO2 emissions, this paper took the panel data of 30 provinces in China from 2011 to 2019 as a sample, used the entropy method to analyze the digital economy level of each province, and built a double fixed effect model to empirically analyze the 'positive U-shaped' or 'inverted U-shaped' relationship between the digital economy and energy or between the digital economy and CO2 emissions. The results showed that: (1) There were inter-provincial and regional differences in the level of digital economy in China. Guangdong Province and China' s eastern region had the highest level of digital economy, while Qinghai Province and the western region had the lowest level of digital economy. (2) Both the digital economy and ECSC and the digital economy and CESC had significant ' positive U-shaped' relationships, while the digital economy and ECST, the digital economy and ECEF, and the digital economy and CEEF all had significant 'inverted U-shaped' relationships. The energy-saving effect of the development of the digital economy was greater than the carbon emission reduction effect. (3) There was heterogeneity in the nonlinear relationship between the digital economy and ECSC, ECST, and ECEF, the digital economy and CESC, and CEEF in the eastern, central, western, and northeastern regions. (4) Digital infrastructure, digital innovation environment, digital user scale, and digital industry scale had different nonlinear effects on ECSC, ECST, and ECEF, as well as on CESC and CEEF. Accordingly, to provide empirical support and a theoretical basis for China's development of the digital economy while taking into account the effects of energy conservation and carbon emission reduction, this study puts forward relevant policy suggestions from three aspects: narrowing the gap in the level of digital economy, formulating digital economy development policies, and focusing on key points for the development of the digital economy. These suggestions are also conducive to boosting China's goals of reaching peak carbon emissions and achieving carbon neutrality. [ABSTRACT FROM AUTHOR]
