Summary: China has a complete industrial system that leads to massive natural resource consumption. This study analyzes the utilization of natural resources in China from 2002 to 2017, finding that the additional consumption of natural resources for treating environmental pollutants is almost as significant as the consumption of natural resources itself. The majority of natural resources come from intermediate inputs. Factors such as economic scale, labor efficiency, and fixed asset investment intensity positively affect resource consumption, while factors such as final use level, fixed asset investment efficiency, and natural resource intensity negatively affect resource consumption.

Summary: Based on the analysis of data from 330 prefecture-level cities in China from 2003 to 2017, this study found that carbon emissions in Chinese cities increased to varying degrees during the study period and exhibited a distinct spatial distribution pattern. Additionally, although the decrease in carbon intensity played a significant role in reducing carbon emissions, it was not enough to offset the incremental gains associated with economic growth. The temporal and spatial impacts of human activities on carbon emissions in most cities were not synergistic.

Summary: This paper investigates the decoupling between economic growth and energy consumption in various sectors of the Chinese economy from 1995 to 2015. It found that China experienced weak decoupling followed by strong decoupling in its sectors, with changes mainly occurring due to financial crises, international trade growth, and less energy consumption. The production effect was identified as a positive driving factor for decoupling, while the energy intensity effect played a negative role.

Summary: This study analyzes data from 335 cities in China and uses the standard deviation ellipse method to depict the unbalanced and differential spatiotemporal evolution patterns of environmental emissions and socioeconomic elements. The study finds decoupling trends among carbon emissions, GDP, and population, and reveals that economic growth has been the main driver of carbon emissions and air pollution nationally but its role has weakened. The study also identifies decreases in energy intensity and carbon and pollution intensities as the main factors contributing to emissions reductions. The underlying reasons for the unbalanced spatiotemporal patterns are differentiated spatiotemporal economic structure evolution, regional heterogeneities in energy intensity and efficiency, and cross-region power energy transmissions. Policy suggestions can be made based on these findings to address the imbalances and promote carbon mitigation, air quality improvement, and high-quality social-economic development at the city level.

Summary: This paper proposes a grey box model for fuel consumption prediction of wing-diesel hybrid vessels based on feature construction. By using both parallel and series grey box modeling methods and six machine learning algorithms, twelve combinations of prediction models are established. A feature construction method based on the aerodynamic performance of the wing and the energy relationship of the hybrid system is introduced. The best combination is obtained by considering the root mean square error, and it shows improved accuracy compared to the white box model. The proposed grey box model can accurately predict the daily fuel consumption of wing-diesel hybrid vessels, contributing to operational optimization and the greenization and decarbonization of the shipping industry.

Summary: Demand-side management is crucial to smart energy systems. This paper proposes a data-driven approach to understand the relationship between energy consumption patterns and household characteristics for better DSM services. The proposed method uses a clustering algorithm to generate optimal customer groups for DSM and a deep learning model for training. The model can predict the possibility of DSM membership for a given household. The results demonstrate the usefulness of weekly energy consumption data and household socio-demographic information for distinguishing consumer groups and the potential for targeted DSM strategies.
