Summary: We evaluated the spatiotemporal characteristics of wind power density (WPD) in the Mediterranean and Black Sea regions. Using hourly wind speed data from ERA5 of ECMWF spanning over 62 years, we revealed the spatial distributions of WPD at different time scales. The study identified the Gulf of Lion and Aegean Sea as the most prominent regions in terms of WPD. Additionally, the diurnal variation, variability indicators, and the performance of five commercial turbines in the study area were investigated.

Summary: The onshore wind energy sector in Brazil has experienced rapid growth in recent years, reaching a 9% share in the country's energy matrix. While offshore wind installation is currently non-existent in Brazil, research has shown significant untapped energy potential. This study aims to conduct an economic analysis for offshore wind projects in Brazilian waters using CAPEX and LCOE indicators, identifying economically and energetically favorable regions. Results suggest that the Northeast region of Brazil, particularly between Maranhao and Rio Grande do Norte states, offers lower Levelized Cost of Energy and Capital Expenditure. Other potential but less promising areas for offshore wind farm deployment include regions between Rio de Janeiro and Espirito Santo states, as well as between Santa Catarina and Rio Grande do Sul states.

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.
