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 study provides a more rigorous and novel methodology to estimate wind electricity yield, considering factors such as wind classes, hub height related capital expenditures, and limitations induced by extreme wind gusts. The results show that there exists an optimal hub height for cost-effective electricity generation, and exceeding this height does not justify the increase in capital expenditures. Additionally, turbines of different wind classes exhibit variations in full load hours and hourly generation profiles.

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 study examines the impact of climate change on the electric power sector in the United States, showing that climate change could potentially increase risks on both the demand and supply sides simultaneously, significantly affecting long-term planning decisions. It was found that climate change impacts could result in an increase in installed capacity in the southeast U.S., driven mainly by an expected rise in peak demand during the summer, leading to higher investment costs over the next 30 years.

Summary: The proportion of global electricity generated by wind is increasing. Concerns about the impact of onshore wind farms on local winds and ecosystems exist. This study evaluates the long-term effects of onshore wind farms on wind speeds and distribution patterns using Terra-Climate and ERA5 datasets. The results suggest that the impact of wind farms on global wind speeds is minimal and far less than other natural phenomena such as oceanic/atmospheric oscillations.

Summary: There is a need to assess the sustainability of global fishing in the face of climate change, particularly in artisanal fishing which is crucial for livelihoods and food security in coastal countries. The ability of the artisanal sector to sustain this reliance depends on economic efficiency and the changing productivity of target species under climate change. Our study examines the historical changes in technical efficiency within artisanal fleets in relation to temperature anomalies, market prices, and fuel costs, showing how climate-induced changes could impact the efficiency of these fleets and exacerbate fishing capacity issues.

Summary: Aviation's contribution to global warming exceeds common perceptions, with a significant impact from a mix of climate pollutants despite a relatively low CO2 emission rate. Forecasted simulations suggest that aviation's warming contribution will continue to rise, but measures such as reducing air traffic scale or transitioning to carbon-neutral fuels can effectively mitigate its impact.

Summary: We conducted a probabilistic assessment of CO2 storage capacity in major sedimentary basins in China, showing that 10 major basins have the potential to store an average of 1350 Gt of CO2 in the next 30 years. Our analysis suggests that underground carbon storage in China, combined with other solutions, could help meet the goals of mitigating global warming by 2060, as per the Announced Pledges Scenario (International Energy Agency). Geological formation attributes were found to be major sources of uncertainty affecting model outputs and associated uncertainty.

Summary: Assessing the wind climate involves various wind speed models, including wind atlases, reanalysis products, regional climate, and global climate models. This study evaluated 68 wind speed models of different types for their predictive power on mean wind speed, wind speed distribution, and temporal variability. Ensembles of models were found to improve model accuracy compared to individual models, with wind atlases showing the best performance at mountainous locations. It is concluded that individual models should be validated before use, and ensembles are recommended for better predictive power.
