Summary: During the COVID-19 pandemic, the economic recession led to a decrease in energy demand and consequent shrinkage in natural resource prices. This resulted in a loss of interest and competitiveness in renewable energy projects, hindering the achievement of sustainable development goals. A study conducted in China examined the causal relationship between renewable energy investments and green finance, and found that IR, REO, and GF exhibited more volatility compared to GDP and IEP.

Summary: Aviation heavily relies on liquid fossil fuel, but sustainable aviation fuels (SAF) are proposed as a solution. Analysis of aviation roadmaps for net zero 2050 shows a reliance on biogenic SAF in the short term and synthetic e-kerosene in the long term. However, scaling up SAF production poses challenges as it competes with land needed for carbon removal, clean energy, and CO2 storage. The conflict between SAF production and global climate goals is not recognized in the roadmaps or public debate.

Summary: This study quantifies the techno-economic potential of using solar photovoltaics (PV) to support heat pumps (HP) for replacing natural gas heating in North American residences. Simulations compare different heating systems, including PV with grid electricity and HP with grid electricity, to identify conditions for lower life cycle cost. The results show that PV becomes a hedge against rising prices when inflation rates are high or PV capital costs are low, increasing the adoption of HPs and reducing carbon emissions. The study also discusses the impact on energy policy, such as rebates and utility business models.

Summary: Ball milling is a grinding method that utilizes rotating drums and specific diameter balls to comminute materials. It offers advantages such as high capacity, predictable fineness, reliability, safety, and simplicity, but is limited by its high weight, energy consumption, and costs. To overcome these limitations, this study presents an open source, customizable ball mill designed using free and open source hardware and distributed digital manufacturing. It offers a cost reduction to $130 for an AC-powered version and $315 for a switchable power version that allows off-grid operation, using a solar module and battery. The use of solar photovoltaic energy improves power reliability and portability in field environments, and the open source design allows for size reduction of silicon particles from millimeter to nanometer scale.

Summary: Although open source DAQ systems have been published, closed source proprietary systems are still widely used despite their high costs. However, the high costs limit access to high-quality DAQ in low-resource settings. While the global library of open source electronic designs is expanding rapidly, current open source devices often lack the ability to scale up or easily integrate with other designs. This article introduces and tests a new framework, the Broadly Reconfigurable and Expandable Automation Device (BREAD), which allows for the development of new open source electronics with plug-and-play functionality.

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.
