Summary: The progress of onshore wind expansion varies globally and cannot be concluded solely based on installed capacity and capacity factor. This study quantifies and compares the effectiveness and efficiency of wind potential use for the top 40 countries in installed capacity. The results show that China, Brazil, and Italy use their wind potential more efficiently, while the USA and India consider wind resource efficiency adequately. Germany has the highest effectiveness despite low efficiency. This highlights the importance of evaluating wind energy expansion based on effectiveness and efficiency rather than just installed capacity and capacity factor.

Summary: The goal of this study is to quantify the meteorological, geographical, and technical properties of the current global offshore wind turbine fleet. The factors studied show high regional variability, with European wind turbine sites providing higher wind resources compared to Asian sites, where turbines operate in shallower water closer to the shores. These findings suggest that wind potential and siting criteria for wind turbines differ depending on the country.

Summary: This paper presents a study on the DC fault transient of a meshed DC grid integrated with high-temperature superconducting (HTS) HVDC cables for offshore wind power integration. A four-terminal meshed DC grid model with a +/-100 kV DC voltage rating is developed, and DC circuit breakers (DCCBs) are employed to manage DC cable faults. Through fault scenario studies with different fault locations and protection delays, it is found that the faults on the faulted cable do not affect the functioning of other healthy cables and that the long delay of DC fault protection does not result in excessive fault current and the quenching of healthy cables. Extensive simulations in PSCAD/EMTDC software validate the research findings.

Summary: A globalized solar PV module supply chain has saved costs for the United States, Germany, and China, resulting in billions of dollars in savings. However, if a localized supply chain is implemented in the future, solar module prices may increase by 20-25% in 2030. Complementary policies are needed to address welfare distribution effects and potential technological crowding out.

Summary: Wind and solar photovoltaic power are vital elements in the transition to renewable energy systems. This study estimates the global metal demands for electrical grid systems associated with wind and utility-scale PV power by 2050. The results show that these electrical grids require large quantities of metals, with copper having the highest demand, followed by steel and aluminum. Power cables are the most metal-consuming electrical components. The study also discusses the decommissioning and recovery potential of electrical grids.

Summary: The feasibility of suspended inter-array cabling between two floating offshore wind turbines is investigated in this study. Power cables, supported by buoyancy modules, are kept afloat midwater below the sea surface. The study examines different sizes and materials of power cables and finds that lightweight cables are more suitable for suspended configurations. Configurations using buoys have lower maximum effective tensions and lower minimum bending radius compared to configurations with buoyancy modules. Power cable excursions do not exceed the mooring line anchor positions of the wind turbines and the hang-off angles are influenced by the motions of the turbines.

Summary: This study presents a novel configuration of suspended inter-array power cables using subsea buoys, which allows the cables to float between the seabed and the sea surface. The results indicate that this new cable configuration is feasible, and smaller buoys are more suitable than larger ones.
