Summary: This paper investigates the driving factors of wind energy consumption in 17 major consuming countries using the logarithmic mean Divisia index (LMDI) method. It identifies renewable energy share and improvements in energy intensity as the main factors affecting wind energy consumption. Forecasts show that Canada, Sweden, China, and Germany are expected to have the highest compound annual growth rates (CAGRs) in wind energy consumption. Countries with high shares of renewable energy like Spain, Portugal, and Denmark are predicted to have lower CAGRs. Future increases in wind energy consumption will rely on the continuous rise in renewable energy share, which is influenced by energy policies promoting the switch from fossil fuels to renewables.

Summary: A novel Bi2WO6/Si heterostructure photocatalyst was developed in this study, which showed a shift of the Fermi level to the valence band, effectively reducing the difficulty of electron holes generation. The photocatalysts with special branch structure achieved an increased surface area and the ability to absorb visible light. The presence of heterojunction enhanced the separation of photo-excited electron-hole pairs and prolonged the electron lifetime, resulting in efficient reduction of CO2.

Summary: The COVID-19 pandemic has disrupted global metal mining and supply chains, leading to a 10-20% reduction in global metal mining in 2020. This reduction resulted in losses of approximately $117 billion in global economic output, reduced CO2 emissions by about 33 million tonnes, and saved 78,192 disability-adjusted life years. Copper and iron mining had the most significant contribution to these effects. China and the rest of the world, particularly America, were the most affected. The cascading effects of the metal mining disruption associated with the pandemic on the economy, climate change, and human health should be considered when designing green economic stimulus policies.

Summary: In the current energy and geopolitical crises, sustainable energy supply and use are crucial in addressing climate change and transitioning to a low-carbon economy. The supply chain risks of fossil fuels are intertwined with sustainable production and consumption, as outlined in the Sustainable Development Goals (SDGs). This study examines the scarcity-weighted fossil fuel extractions and footprints of nations, identifying hidden supply chain risks and highlighting the need to incorporate scarcity footprint into the SDG framework for more targeted and explicit implications in global fossil fuel management. Countries with high risks should accelerate their energy transitions and strengthen international cooperation from both supply and demand sides in the complex international energy trade relations.

One promising option is Carbon fiber reinforced thermoplastic composites (CFRTPs), which possess characteristics such as light weight, high strength, and high temperature resistance. This study investigated the effects and mechanisms of hollow glass beads (HGB) on the thermal insulation and mechanical properties of carbon fiber-reinforced thermoplastic polyphthalazine ether sulfone ketone composites (CF/PPESK). The addition of HGB significantly improved the material's thermal insulation performance and mechanical strength, making it a promising candidate for CFRTPs applications.

Summary: This study examines the impact of land cover, vegetation health, climatic forcings, elevation heat loads, and terrain characteristics on land surface temperature distribution over West Africa. The random forest model performs the best in downscaling predictands. The southern regions consistently exhibit healthy vegetation, while areas with unhealthy vegetation coincide with hot land surface temperature clusters. Positive Normalized Difference Vegetation Index trends in the Sahel highlight rainfall recovery and subsequent greening. Southwest winds cause the upwelling of cold waters, resulting in low land surface temperatures in southern West Africa. Considering LVCET factors is crucial for prioritizing greening initiatives and urban planning.
