Summary: The study shows that the Central Western Europe power system can achieve decarbonization targets at both 2 degrees C and 1.5 degrees C, while providing reliable low-carbon electricity. However, the system costs for the 1.5 degrees C scenario are found to be twice as high as those for the 2 degrees C scenario, primarily due to the high cost of negative emission technologies such as direct air carbon capture (DAC).

Summary: Meeting energy needs and ensuring ecological sustainability are important tasks. This study investigates the influence of nuclear power and renewables on achieving carbon neutrality in major nuclear power countries. The findings show that nuclear energy reduces carbon emissions in Russia, while solar and wind power contribute to emission reduction in the U.S., Russia, and France. However, China's use of nuclear and renewables for carbon neutrality is inefficient.

Summary: Research shows that shallow reservoirs in the tropics emit significant greenhouse gas emissions. In Ghana, although existing and planned hydro resources may only account for less than 1% of their future energy demand, their cumulative emissions can consume 40% of the country's carbon budget under the Paris Agreement. Therefore, instead of constructing more dams, it would be more aligned with the Paris goals for Ghana to focus on energy efficiency and diversifying renewable energy options.

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.
