Summary: The demand for affordable and reliable flood warning systems has increased due to the rise in the number and severity of flood disasters. The federal government and private sectors are developing low-cost sensors for flood monitoring and warning, sometimes through collaboration. These sensors can enhance flood warning systems by improving coverage and lead time, and they have significantly lower production costs compared to existing sensors with similar capabilities.

Summary: This study investigated the thermal comfort and energy consumption factors of a representative Tibetan Buddhist house with attached sunspace in Gannan. The results show that the most relevant parameters are roof insulation thickness and roof thickness. The optimum thickness of rammed earth is 1.1-1.2 m, and the design range of thermal insulation thickness is 10-90 mm, with 10-40 mm being the best. The best orientation of the attached sunspace is south, and the glazing type has a little effect on thermal comfort and limited impact on energy consumption.

Summary: With the promotion of renewable energy utilization and the trend of a low-carbon society, the real-life application of photovoltaic (PV) combined with battery energy storage systems (BESS) has thrived recently. An optimization model is proposed for evaluating sizing, operation simulation, and cost-benefit of the PV-BESS integrated energy systems. The simulation results demonstrate the feasibility and effectiveness of the proposed model in an industrial area. Furthermore, the cost-benefit analysis reveals the cost superiority of PV-BESS investment compared with the pure utility grid supply.

Summary: The rate of municipal solid waste (MSW) generation in developing countries is continuously increasing in proportion to the gross national product. This study aims to analyze the MSW management activities in India's capital, Delhi, and the cost-benefit analysis of MSW management systems. The results show that only about 80% of the garbage generated in Delhi is collected and storage, collection, transportation, and recycling information were gathered from various departments. The study also reveals the potential for composting and bio-methanation of MSW with high organic moisture content.

Summary: Low-cost optimization measures have the potential to significantly reduce the need for invasive and costly retrofitting interventions. However, due to the lack of data collection processes and optimal implementation strategies, these measures are often underutilized. This study used a unique dataset of 92 residential buildings to identify the most effective actions for energy savings. By training an Artificial Neural Network and analyzing sensitivity indices, the study quantifies the impact of each measure on energy consumption variability and identifies the most probable intervals of energy savings.

Summary: This paper discusses the trade-off between cognitive costs and values in an individual's decision-making process, and analyzes the fundamental properties required for the decision to stop thinking to be represented by a cost-benefit analysis. Additional properties are then provided to add structure to the value of reasoning function. The paper demonstrates how the model applies to various contexts and sheds light on patterns of behavior where the cost-benefit approach does not seem to hold.

Summary: Despite the lack of studies on the benefits and costs of pollinator conservation, a survey was conducted among three US universities to assess the benefits of becoming Bee Campus USA certified. The study also examined the impact of reminders on student sustainability fees on willingness to pay. The results showed that the net benefits for each university were mostly positive, with information reminders having little effect on support for pollinator conservation.

Summary: This paper examines the impact of real-time pricing and load automation on residential distribution systems. The study finds that implementing real-time pricing can result in an aggregate welfare gain of 39 USD per customer and year. However, it also notes that RTP and load automation may significantly increase peak system load. Introducing a market-based demand management system can further enhance welfare gains and reduce grid investment.

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: Russia's weaponization of gas supplies shook the energy security of Central and Eastern Europe in 2022. The region responded by increasing alternative energy supplies and developing new gas supply routes. Renewable energy, nuclear energy, and hydrogen play important roles in the long-term. Mitigating the impact of this shock requires the EU to prioritize the integrity of its energy market.

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.

Summary: This paper investigates China's energy trade stability using a survival analysis approach. It finds that the energy trade linkages between China and 153 other countries are complex and unstable, with short periods of trade with many countries. Geopolitically risky regions, such as the Middle East and Africa, have the lowest trade stability. Climate risks have significant effects on energy trade stability. The paper proposes several policy options to improve energy trade stability in China, with special attention to increasing global climate risks.

Summary: This study estimates the willingness to pay of Indian urban consumers for a continuous supply of electricity using contingent valuation method. The findings show that the amount consumers are willing to pay depends on the duration of power outages, with households preferring shorter outages. Income and environmental attitude also positively influence higher willingness to pay. These insights can inform policymakers in designing more reliable and customer-centric energy generation and distribution models.

Summary: The study finds that oil price shocks have a negative impact on Africa's energy transition, particularly in rural areas and net crude oil exporting countries. However, oil price shocks cannot explain the urban-rural differences in clean energy access. Therefore, increasing investment in clean energy and technologies in rural areas is necessary to enhance the resilience of the energy sector to oil price shocks.

Summary: The Renewable Energy Certificate (REC) is considered an innovative technology for building a green society. This study investigates the impact of REC purchases on stock return and volume in Taiwan between 2017 and 2021. The findings suggest that REC purchases have a positive effect on stock returns of manufacturing firms but not service firms. The frequency of REC purchases is also an important factor in the relationship between REC purchase and firm value. Additionally, the study reveals that public attention to environmental pollution plays a crucial role in positive stock returns and volume, while ESG disclosure is negatively associated with returns and volume.

Summary: This paper addresses the challenges of governing energy procurement from a mix of non-hydropower renewable energy sources supplied by independent producers. Building on political economy analysis and five case studies of independent producer projects from Ethiopia, it seeks to understand the root causes of the protracted delays and limited extent of procurement by independent producers. The key contestations lie in managing long term contracts, risk, uncertainty and in developing the institutional and human capacity to transition.
