Summary: Using a non-linear autoregressive distributed lag time-series analysis, this paper examines the causal relationship between climate change, the tourism sector, and energy consumption in Turkey. The balancing act between a country's economic growth and the environmental degradation caused by tourism and energy is vital for addressing the issue and creating effective economic policies. The findings suggest that a decrease in tourist arrivals and an increase in renewable energy consumption may contribute to lowering temperatures, while an increase in non-renewable energy consumption may lead to temperature rise. Mitigating climate change and promoting sustainable economic growth through efficient tourism policies are crucial.

Summary: This study examines the nonlinear impact of non-renewable and renewable electricity consumption on the economic development of Thailand. The results show that renewable electricity consumption has a negative influence on economic growth during the expansion regime, but a positive influence during recession regime 2. Non-renewable electricity consumption has a positive impact on growth only during the expansion regime. Importantly, the effects of non-renewable and renewable electricity consumption on economic development are asymmetric between the two regimes.

Summary: This paper focuses on climate change in Turkey caused by energy consumption. The results show a negative relationship between renewable energy consumption and temperature, indicating that an increase in renewable energy can help decrease temperature. On the other hand, non-renewable energy consumption has a positive relationship with precipitation, suggesting a negative effect on climate change. Encouraging renewable energy consumption through government incentives can be a powerful solution to mitigate the negative effects of climate change in Turkey.

Summary: The South African government is addressing global warming issues and striving to achieve the UN Sustainable Development Goals-7 & 13 (affordable clean energy and climate change mitigation). This article presents a novel approach using dynamic autoregressive distributed lag (ARDL) simulations to study the nexus between CO2 emissions, renewable energy consumption, militarization, and economic growth in South Africa. The findings reveal a long-run equilibrium relationship between these variables, differing causality results, and support for the treadmill theory of destruction and the Environmental Kuznets Curve (EKC) hypothesis in South Africa. The study recommends a synergy between defense, renewable energy, growth, and environmental policies to promote and maintain environmental quality in South Africa in both the short and long term.

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.
