Summary: Pakistan is moving towards increased use of coal, which is estimated to reach 30% of the country's energy mix by 2030. This study analyzes the relationship between coal imports, indigenous reserves, and CO2 emissions. The results show that coal consumption and imports are interrelated, while coal production has been low. Factors such as energy intensity and coal share affect coal utilization. Economic and population activity also contribute to increased coal consumption. The study also discusses the potential of clean coal technologies in reducing emissions.

Summary: Insufficient and time-delayed air supply reduces the performance and durability of fuel cell system in vehicular application. A decoupling control method based on feedforward structure is proposed to independently control the intake mass flow and pressure. The proposed method effectively reduces the interaction of the coupled loops, achieving higher accuracy and stability, and has better anti-disturbance performance to air speed turbulence under varying vehicle speed.

Summary: In order to achieve its goals of carbon emissions peak and neutrality, China requires collaboration across all sectors. This study explores different scenarios to determine the pathways for emissions reduction and the timing of decoupling economic growth from CO2. The results indicate that China's carbon emissions will peak between 2025 and 2030, with the agriculture, forestry, livestock, and fishing sectors being the first to reach peak emissions. All sectors, except for electricity, gas, and water production and supply, are projected to achieve carbon peak by 2030.

Summary: Despite differences in climatic regimes, OECD countries are major energy consumers and greenhouse gas emitters. However, no studies have analyzed the long-term influential factors of carbon emissions for these countries. This research uses the Log Mean Divisia Method I and decomposition analysis to investigate the driving forces of CO2 emissions from 1990 to 2019. The study provides valuable insights for reducing CO2 emissions and informing climate change policies. Evaluation: 8/10.

Summary: Conventional fuel consumption prediction models using neural networks often have low accuracy and poor correlation due to the use of driving parameters like speed and acceleration as training inputs. To address this, this study introduced jerk as an important variable in the training input of four selected neural network models: long short-term memory (LSTM), recurrent neural network (RNN), nonlinear auto-regressive model with exogenous inputs (NARX), and generalized regression neural network (GRNN). Evaluation of the prediction performance using root-mean-square error (RMSE), relative error (RE), and coefficient of determination (R2) revealed that the LSTM model outperformed the others. Overall, the addition of jerk improved the accuracy of fuel consumption prediction, with LSTM showing the greatest improvement under high-speed expressway scenarios, reducing RMSE by 14.3%, RE by 28.3%, and increasing R2 by 9.7%.

Summary: This study provides an in-depth analysis on the decoupling of economic growth from fossil fuel use across 130 countries from 1992 to 2019, examining the impact of urbanization, industrialization, trade openness, and the share of renewable energy sources. The results suggest that developing renewable energy sources is the key factor in reducing fossil fuel consumption across countries at all levels of development, and wealthier countries tend to consume more fossil fuels.

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.
