Summary: This study establishes an air quality-heating model to evaluate the potential impact of reducing scattered coal consumption in rural areas. The results show that the coal substitution policy can reduce PM2.5 concentrations by about 20 μg/m³ in the Beijing-Tianjin-Hebei and surrounding areas during the heating season. Predictions suggest a significant reduction in PM2.5 concentrations by 2030, with additional improvements possible through clean power development.

Summary: The adoption of solar photovoltaic and electrical energy storage technologies by end users is often assessed based on metrics of future cash flow like Net Present Value (NPV). However, the lack of consideration for short- and long-term transitions towards low-carbon electricity systems can significantly impact the profitability estimation of these technologies, pointing to a potential underestimation of around 20% in scenarios with high renewables, moderate flexibility, and high electrification levels.

Summary: To achieve the decarbonization of global electrical systems using photovoltaics (PVs) in the 2050-2060 decade, 63.4 TW of PV would need to be installed. This article explores a model for ramping up PV manufacturing toward this goal, assuming financially rational decisions by investors. The study demonstrates that sustainable manufacturing ramp-up is possible and that the introduction of disruptive technologies can accelerate and reduce the cost of deploying the necessary manufacturing capacity.

Summary: In this study, Arabian desert sands were examined to identify optimal thermal energy storage and solar radiation absorption properties. The purest quartzose sands, with over 99% quartz content, were found to have the best thermophysical and thermo-optical properties, making them ideal for use as a sensible thermal energy storage medium and solar absorber material.

Summary: This study introduces a mathematical formulation of energy storage systems into a generation capacity expansion framework and finds that dynamic parameters of batteries do not significantly impact the optimal generation portfolio, while battery degradation leads to substantially different generation expansion outcomes. Battery energy storage is economically viable for 2020 only under strict carbon emission constraints, but by 2050, it becomes an attractive option for deep decarbonization given projected technology advances and cost reductions.

Summary: This study examines the factors affecting the transition towards renewable energy sources in 21 OECD nations from 1990 to 2020. The findings reveal that environmental policy stringency, environmental related tax, and development of environment related technology contribute to the transition towards renewables. The study also suggests the need for faster progress and restructuring of environment-related policies to encourage the use of cleaner energy sources.

Summary: The paradigms of teaching and learning are changing rapidly with the advancement of information and communication technology, and this is also true for the study of English language. Various approaches like flipped learning, blended learning, and a content-based approach can create a conducive environment for learners. However, the cultivation and promotion of critical thinking in students is the most efficient way to facilitate their learning process.

Summary: Learning-by-doing in production leads to higher learning benefits through coopetition effect, while intensifying price competition and potentially lowering overall profits for OEMs. The impact of product substitution rate on OEMs' profits is mixed, and simpler pricing strategies may outperform strategic differential pricing. Asymmetric production learning and CM's pricing power also play significant roles in OEMs' decisions and profits.

Summary: Due to the increasing emission of greenhouse gases and global warming, the development of renewable energy has become crucial. Policies supporting renewable energy play a significant role in increasing the deployment of renewable energy technologies, regardless of a country's group. Developed oil countries have more capacity to support renewable energy projects than oil developing countries due to their higher efficiency in renewable energy policy.

Summary: This research examines the relationship between learning-by-doing rates in manufacturing and firms' diversification decisions. The results indicate that firms in high learning-by-doing industries are less likely to diversify, supporting the argument that the first-order knowledge generated from learning-by-doing is difficult to transfer to new contexts. However, it is also argued that firms in high learning-by-doing industries can develop general know-how that is applicable in other similar contexts, leading them to choose diversification into industries with similar learning-by-doing rates.
