Summary: The study investigates the causal relationships between global surface temperature changes and relevant economy-related factors, providing a clearer regime for authorities. It finds that the growth rate of CO2 productivity and energy consumption in industrial, service, and transport sectors positively correlates with global surface temperature changes in the long run. However, the contributions of agricultural and transport sectors to temperature changes are not clear due to their bidirectional causality. Improving energy efficiency and consumption in these sectors should also be a significant concern. The study also highlights the positive causal relationship between population density and renewable energy contribution to global surface temperature change.

Summary: This paper investigates the impact of population aging on energy consumption structure in mainland China using a multivariate panel regression model. The results show that the total energy consumption in mainland China is increasing, with regional heterogeneity. The high-value energy consumption zones are concentrated in China's eastern region. The energy consumption structure is evolving with a decreasing share of coal consumption. Population aging has a significant positive correlation with national-level energy consumption structure, but a negative effect in medium-value coal consumption zones at the provincial level. GDP, the share of secondary industry, and energy price also play important roles.

Summary: Green finance is considered an important tool in the transition to a low-carbon economy, but its impact on carbon emissions has been questioned. Using panel data from 30 provincial administrative regions in China from 2008 to 2019, this study finds that the development of green finance has a significant negative effect on carbon emissions through optimizing energy consumption structure and upgrading industrial structure. Additionally, it is found that green credit has a more pronounced effect on carbon emissions reduction compared to green bonds. Regional heterogeneity is also considered, with the results showing that green finance can reduce carbon emissions in central and western regions, but not significantly in the eastern part of China. Therefore, regional characteristics should be taken into account when implementing green finance policies to effectively reduce carbon emissions.

Summary: China's energy structure is heavily reliant on fossil fuels, particularly coal consumption. The global coal market was impacted by the COVID-19 outbreak in January 2020, leading to negative economic growth in many countries. To reduce carbon emissions and break the dependence on economic development, China set a target to peak carbon emissions by 2030. This article aims to provide directions for the sustainable development of China's coal industry. Based on a macroenvironment and situation analysis, the article concludes that, due to geopolitical factors and the increasing demand for coal in China, the share of coal in the country's energy structure will not decrease significantly in the long term. The main directions for sustainable development include ensuring the safety of coal energy storage, improving safety supervision, coordinating regional energy development, promoting clean and efficient coal utilization, and strengthening international coal strategic cooperation.

Summary: This paper investigates the driving factors of wind energy consumption in 17 major consuming countries using the logarithmic mean Divisia index (LMDI) method. It identifies renewable energy share and improvements in energy intensity as the main factors affecting wind energy consumption. Forecasts show that Canada, Sweden, China, and Germany are expected to have the highest compound annual growth rates (CAGRs) in wind energy consumption. Countries with high shares of renewable energy like Spain, Portugal, and Denmark are predicted to have lower CAGRs. Future increases in wind energy consumption will rely on the continuous rise in renewable energy share, which is influenced by energy policies promoting the switch from fossil fuels to renewables.

Summary: To address climate change, governments around the world have set their own carbon neutrality targets based on their own realities. This study conducts a literature review to propose narrow and broad definitions of energy waste and a theoretical framework to comprehensively reduce energy waste. However, there is currently no clear definition of energy waste and lack of consensus on the topic. Most previous studies focus on reducing unnecessary energy consumption through management techniques, while digital technologies can also play a facilitating role. Future research directions include case studies to further understand energy waste and developing a more detailed framework on the topic.

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.
