The growing urgency for sustainable energy solutions necessitates a deeper understanding of the environmental impacts of renewable technologies. This article aims to synthesize and analyze Life Cycle Assessments (LCA) in this domain, providing a comprehensive perspective. We systematically categorized 2923 articles into four sectors: (1) photovoltaic systems, (2) wind energy systems, (3) solar thermal systems, and (4) materials for auxiliary industry supporting these systems. A comparative analysis was conducted to identify methodological consistencies and disparities across these sectors. The findings reveal diverse methodological approaches and a range of environmental impacts, highlighting the complexities in assessing renewable energy systems. The article underscores the significance of material selection in photovoltaic, solar, and wind systems, providing a critical overview of the current state of LCA research in renewable energy and stressing the need for standardized methodologies. It also identifies gaps in recent research, offering insights for future studies focused on integrating environmental, economic, and social considerations in renewable energy assessments. Integrating environmental assessments provides a robust framework for making informed decisions on sustainable technologies. The findings are critical for projects that balance technological needs with sustainability goals.

This paper describes the characteristics of worldwide scientific contributions to the field of electric vehicles (EVs) from 1955 to 2021. For this purpose, a search within the Scopus database was conducted using “Electric Vehicle” as the keyword. As a result, 50,195 documents were obtained through analytical and bibliometric techniques and classified into six communities according to the subject studied and the collaborative relationships between the authors. The most relevant publications within each group, i.e., those related to the most publications, were analyzed. The result shows 104,344 authors researching on EVs in 149 different countries with 225,445 relations among them. Furthermore, the most frequent language in which these publications were written as well as the h-index values of their authors were analyzed. This paper also highlights the wide variety of areas involved in EV development. Finally, the paper raises numerous issues to consider in order to broaden knowledge about EVs, their efficiency, and their applications in the near future for the development of sustainable cities and societies.

It also identifies gaps in recent research, offering insights for future studies focused on integrating environmental, economic, and social considerations in renewable energy assessments.As a case study, an LCA was used to evaluate two energy supply methods for a sensor network: one connected to the public grid and another powered by a photovoltaic panel. The off-grid system, while more environmentally friendly by reducing reliance on non-renewable energy sources, posed challenges due to the high environmental impact of battery production and disposal. Integrating environmental assessments provides a robust framework for making informed decisions on sustainable technologies. The findings are critical for projects that balance technological needs with sustainability goals.

Advancements in electronics and the rapid evolution of technology necessitate that higher education institutions continuously adapt their curricula to accommodate new teaching methodologies and emergent tools. This paper examines the impact of integrating flipped learning and digital laboratories into practical sessions of a Basic Electronics course by analyzing 5 years of data. Using an action research methodology, the research was conducted through three phases: traditional in‐person teaching, fully online instruction during the COVID‐19 pandemic, and a hybrid model combining flipped classrooms, digital laboratories, and in‐person sessions. The findings reveal that the hybrid model, blending digital and traditional methods, significantly enhanced student performance, particularly in practical tasks. Furthermore, digital laboratories provide students with a risk‐free environment to simulate real‐world electronic scenarios, fostering deeper cognitive engagement and reducing the cognitive load during in‐person sessions. The flipped classroom structure encouraged active learning and peer collaboration, which led to greater student motivation, lower absenteeism, and improved learning outcomes. Additionally, students demonstrated a marked increase in their ability to apply theoretical knowledge to practical problems, highlighting the effectiveness of this approach in bridging the gap between theory and practice. This model enhances cognitive and motivational learning dimensions, providing a balanced, effective approach to modern engineering education. The results can potentially contribute to the understanding of effective pedagogical strategies in adapting engineering education to meet the challenges of the digital age.

In the context of the global energy sector’s increasing reliance on fossil fuels and escalating environmental concerns, there is an urgent need for advancements in energy monitoring and optimization. Addressing this challenge, the present study introduces the Open Multi Power Meter, a novel open hardware solution designed for efficient and precise electrical measurements. This device is engineered around a single microcontroller architecture, featuring a comprehensive suite of measurement modules interconnected via an RS485 bus, which ensures high accuracy and scalability. A significant aspect of this development is the integration with the Non-Intrusive Load Monitoring Toolkit, which utilizes advanced algorithms for energy disaggregation, including Combinatorial Optimization and the Finite Hidden Markov Model. Comparative analyses were performed using public datasets alongside commercial and open hardware monitors to validate the design and capabilities of this device. These studies demonstrate the device’s notable effectiveness, characterized by its simplicity, flexibility, and adaptability in various energy monitoring scenarios. The introduction of this cost-effective and scalable tool marks a contribution to the field of energy research, enhancing energy efficiency practices. This research provides a practical solution for energy management and opens advancements in the field, highlighting its potential impact on academic research and real-world applications.
