Summary: In this paper, two strategies for reducing cash flow uncertainty in wind energy production due to variable weather conditions are explored. The first strategy involves aggregating output from geographically-dispersed generating units. The second strategy utilizes financial instruments to compensate for unexpected declines in power delivery. Through advanced weather modeling, time series analysis, simulation, and optimization techniques, the effectiveness of these risk management approaches in controlling volumetric risk in Spain is empirically evaluated. Factor analysis techniques are used to decompose remaining risk levels and assess revenue exposure to systematic risk factors for each strategy. New financial contracts and mixed-style strategies are proposed based on the analysis results to better suit the risk positions of market players.

Summary: Household solid fuel use is detrimental to health and the environment. The Indian government's PMUY subsidy has successfully promoted the adoption of LPG by millions of households. However, there is limited understanding of the decision-making process to reduce solid fuel use after transitioning to cleaner fuels. This study found that factors such as household wealth, social status, education level, and the prevalence of LPG use in the village are positively associated with LPG consumption and the discontinuation of solid fuel use. On the other hand, factors such as distance to LPG refill delivery, household size, and the PMUY subsidy are negatively associated with the share of LPG use.

Summary: Economic costs are a major political obstacle to investing in climate change mitigation and adaptation measures. The method of financing plays a crucial role in determining public opposition to government green investments, with debt financing being less opposed than broad-based taxes. This study suggests that credit market tools, such as green bonds and debt for climate swaps, can be politically efficient in increasing support for green financing. Carbon taxes and wealth taxes are found to be the most preferred options.
