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: The study explores a supplier-retailer-customer chain where retailers receive advance payments from suppliers and offer customers credit payments based on a combination of cash and credit. Demand is influenced by selling price and stock age. Optimal pricing and replenishment strategies are determined to maximize total profit, showcasing the importance of advance payments in affecting selling price.

Summary: In this paper, the cost potential of Brazilian offshore wind energy is assessed using a methodological approach that combines spatial suitability analysis and a cost estimation model. The available area for development is mapped and classified based on the Levelized Cost of Energy (LCOE), generating a cost potential map and a cost-supply curve. The results demonstrate that Brazil has a promising market for offshore wind energy, with significant installable capacity and internationally competitive costs.

Summary: In the last three decades, the classical backward bending of the labor supply curve has been extended to the case of the inverted S-shaped labor supply curve. According to this extension, at very low net wage levels near the subsistence income level, the positive shape of the labor supply curve may also be curved backward and become negatively sloped. This S-shaped curve leads to a double-peaked Laffer curve, which includes the possibility of three tax rates that can collect the same tax revenue. This is in contrast to the traditional single-peaked Laffer curve, which has two tax rates with the same revenues.

Summary: This study constructed a universal and relatively simple socioeconomic drought assessment index (SSDWI) and analyzed its application in the Jianjiang River Basin (JJRB) in Guangdong Province, China. The results showed frequent occurrences of socioeconomic drought in the basin, mainly in autumn and winter seasons. However, the probability of drought has declined since 2008, thanks to reservoir scheduling.

Summary: The uncertainty of future revenues caused by the natural variability of the wind resource, climate change, and regulatory risks may hinder investments into wind power generation. Our study reveals that support mechanisms are necessary for wind farms under present and future climates. The cost of support mechanisms varies depending on the country and scenario considered, ranging from EUR 3.8 to EUR 11.5 billion per year in France, EUR 15.5 to EUR 26.5 billion per year in Germany, and EUR 1.2 to EUR 3.3 billion per year in Denmark.

Summary: This paper examines the goods market and labor market based on the Ramsey dynamic general equilibrium (RDGE) model, investigating the effects of productivity increases and income tax rate decreases on macroeconomic variables. The study finds that productivity increases and capital income tax rate decreases lead to a net shift out of aggregate supply (AS) relative to aggregate demand (AD), reducing the relative price of output. Tax rate reductions have a decreasing effect on increased economic activity.

Summary: This study presents a methodology and dataset for examining compound wind and solar energy droughts, as well as the first standardized benchmark of energy droughts across the Continental United States (CONUS) for a 2020 infrastructure. The results show that compound wind and solar droughts have distinct spatial and temporal patterns across the CONUS, and the characteristics of energy droughts are regional. The study also finds that compound high load events occur more often during compound wind and solar droughts than expected.

Summary: This paper provides insights into the optimal configuration of CSP plants with different penetrations of wind power by proposing an unconstrained optimization model. The results suggest that large solar multiples and TES are preferred in order to maximize profit, especially when combined with high penetrations of wind and photovoltaic plants. Additionally, the study demonstrates the economy and feasibility of installing electric heaters (EH) in CSP plants, which show a linear correlation with the penetration of variable energy resources.

Summary: This study investigates the optimization of power density in wind farms and its sensitivity to the available area size. A novel genetic algorithm (PDGA) is introduced to optimize power density and turbine layout. The results show that the PDGA-driven solutions significantly reduce the levelized cost of energy (LCOE) compared to the default layout, and exhibit a convex relationship between area and LCOE or power density.

Summary: Spent coffee grounds are a valuable biogenic waste that can be used as a source of biofuels and valuable chemicals through pyrolysis and solvent extraction processes. The study found that heavy organic bio-oil derived from coffee grounds can be used as a carbon-rich biofuel, while solvent extraction can extract xantines and p-benzoquinone, which are important chemicals for various industries. The results highlight the promising potential of solvent extraction in improving the economic viability of coffee grounds pyrolysis-based biorefineries.
