Summary: Natural gas industry can develop a hydrogen industry based on CO2 capture technology, which can effectively utilize resources, reduce carbon emissions, and facilitate the transition to renewable energy-based hydrogen fuel. A stepwise strategy can be adopted by starting from the idle capacity in the existing natural gas industry to establish an independent supply.

Summary: The study examines the impact of potential changes in energy consumption on carbon dioxide (CO2) emissions, focusing on disaggregated energy consumption sources. The results indicate that nuclear, natural gas, oil, and coal energy have a significant effect on CO2 emissions, while renewable energy is not statistically significant. The study suggests that France should continue to rely on nuclear power for electricity generation and reduce electricity exports to European Union countries to counter the potential natural gas shock from Russia.

Summary: Many countries heavily rely on imported fossil fuels due to limited local resources, which increases their vulnerability to geopolitical instability of suppliers. A science-based methodology is crucial for policy makers to monitor the security of energy supply system. This proposed model quantifies the risk of the supply system by incorporating geopolitical factors and allows for scenario analyses to assess the impact of geopolitical stability and supply interruptions. The model is applied to evaluate the security of the Italian crude oil supply system, identifying potential weaknesses and suggesting the need for diversification.

Summary: Judging the bottom line of China's oil product consumption is crucial for energy security. We categorize oil product consumption into bottom-line and non-bottom-line consumption, and use the DMA method for forecasting. The results show that under different development scenarios, the bottom-line consumption of oil products in 2025 will range from 197.29-213.47 Mt in the low development scenario, 236.21-250.37 Mt in the baseline scenario, and 269.62-285.8 Mt in the high development scenario. By reducing the high development scenario to the low development scenario, non-bottom-line consumption can be reduced by about 22.09-25.32 Mt. The forecast results under different scenarios demonstrate the flexibility and feasibility of future policy combinations in regulating oil consumption. Moreover, each policy scenario will have a different impact on the bottom-line and non-bottom-line consumption of gasoline, kerosene, and diesel, with their respective lower limits in 2025 being approximately 44%, 14%, and 27%.

Summary: This paper investigates the optimization of crude oil-supply composition and introduces the decomposition hybrid interval prediction method and a multi-objective programming model. By setting optimization parameters and risk preference factors, the study achieves the minimum cost and risk of importing crude oil. The results show that the decomposition hybrid prediction method outperforms single prediction methods, and increasing the optimization parameter significantly reduces costs and risks. The total cost of imported crude oil fluctuates sharply, while the total risk decreases with the increase of risk preference factors. The fluctuation of price and risk adjustment factors affects the optimization scheme for oil-supply portfolio.

Summary: In addition to the environmental disadvantages of fossil energy sources, energy security is still a significant concern for economic development and environmental sustainability. This study examines the influence of energy security and its components on crude oil prices, specifically in the United States, from 1970 to 2040. The results show that an increase in aggregate energy security risk leads to a similar 0.9 elasticity increase in crude oil prices. The economic, geopolitical, and reliability perspectives of energy security risk also have positive impacts on oil prices, with elasticities of similar to 2.0, similar to 0.6, and similar to 0.7, respectively. Conversely, an increase in environmental risk leads to a decline and an inelastic (similar to -1.5) change in crude oil prices, indicating the importance of a net zero future and the adoption of clean and alternative energy sources. Additionally, the study finds that crude oil prices respond positively to increased energy expenditures and negatively to increased electricity prices. These results have important policy implications.

Summary: This study examines how international relations impact China's energy security and supply/demand dynamics, with a focus on new energy sources and technological advancements. As the largest energy consumer in the world, China must achieve a balance between energy supply, demand, and sustainable development. The research findings reveal that international relations influence the energy market, particularly due to uncertainties caused by geopolitical events and international tensions that affect energy prices and supply. The study also identifies the differential impact of crude oil prices on the United States and China. Recognizing the relationship between China's energy security and international relations is crucial for effective policy formulation. This study provides valuable insights for policymakers and stakeholders to ensure a sustainable and secure energy future.

Summary: This paper analyzes the gas consumption in hotels on the Adriatic coast, comparing the usage of natural gas and liquefied petroleum gas (LPG) based on hotel size. The study hypothesizes that switching from LPG to natural gas can not only reduce emissions in the hospitality industry but also bring significant economic benefits. The research objectives include conducting a regression analysis to identify various factors affecting gas consumption. The analysis reveals a moderate-strong relationship between the variables, which is a new finding for energy trends in the hospitality sector. Converting from heating oil to natural gas allows hotels to achieve substantial financial savings and reduce overall energy costs. The measures taken by the hospitality industry will positively impact guest perception and can be used as a promotional tool under the green hospitality label.

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.
