Energy conversion devices such as fuel cells, metal-air batteries, and electrolyzers have been envisaged as possible solutions for cutting down the continuous accumulation of greenhouse gases resulting from the combustion of fossil fuel. The bottleneck reaction for these devices is the oxygen reduction reaction (ORR) occurring at the cathode. The…

Green internet of things is important to achieve atmospheric decarbonisation, it is crucial to implement procedures and practices that prioritise resource conservation and environmental protection. However, the growing use of internet of things devices poses a challenge due to their high-energy requirements for data reception and transmission…

The Edison Institute predicts that there will be at least 19 × 10[superscript 6] all-electric vehicles (EVs) in use by 2030. This will produce significant effects on our transportation system and its energy requirements. Investigating these effects is an ideal activity to show the relevance of physics. How efficient are EVs in using energy? What…

We use new survey data from 1,203 households in rural Eastern India to estimate cross-sectional models of overall energy use and embedded emissions. Findings indicate that the primary driver of household energy use is household size and affluence. This is unsurprising and consistent with findings from the engineering literature on energy demand.…

The research aimed to describe the development of solar electric cars as a prop in energy conversion learning using the analyze, design, develop, implement, and evaluate (ADDIE) model and to ascertain the effectiveness of an electric car as a prop in energy conversion learning. Utilization of prop in the learning process is one way to support the…

Metal-air battery technology is a promising new energy storage solution in the green energy economy but also an excellent tool to educate students on the working principles of batteries. A simple yet powerful construction of a metal-air battery is shown, which consists of a plastic mint box, a cathode, an anode, and an electrolyte. Furthermore,…

Fostering students' critical thinking skills is an urgent issue that requires immediate attention. One viable solution to address this is the implementation of project-oriented problem-based learning (POPBL) through the SR-STEM project. This research aims to describe the implementation, effectiveness, and student perception of the POPBL model…

Young students show great interest in solar energy and a genuine curiosity towards the operating mechanisms of a solar cell. This study reports on a methodology that reveals an effective approach in explaining the operation of solar cells to young students with very limited knowledge in solid-state physics. The methodology can be presented in the…

It is now widely understood that societies must rapidly decarbonize to avoid the worst impacts of future climate change. To contribute to this urgent effort, academic libraries should develop an understanding of the carbon footprint resulting from their activities. This article shares the results of an effort at the Penn State University Libraries…

Purpose: Many institutions of higher education have committed to carbon neutrality. Given this goal, the main economic issue is minimizing cost. As for society as a whole, dominant decarbonization strategies are renewable electricity generation, electrification of end uses and energy efficiency. The purpose of this paper is to describe the optimum…

In recent years, solar-powered photocatalytic water splitting for hydrogen production has drawn great attention as a method to supply clean energy and reduce environmental pollution. This approach, driven by solar energy to synthesize hydrogen gas, is completely renewable and can be used to power hydrogen fuel cells to effectively solve the global…

Recognizing the relevance of energy in our lives is essential for ensuring a sustainable future. The lessons offered by education systems could exert an impact throughout the lives of people. This study conducts a review of the content of elementary-level textbooks in Mexico to describe and analyze the scope of these materials and their depth from…

It is not only worth talking about the chances of survival in the fight against emerging environmental and socio-economic threats, but it is necessary to use all possible means to influence public awareness. It is awareness that shapes our attitudes and literacy. The core of these tools is cross-sectoral place-based education. This raises the…

Climate change is real and accelerating. It requires an urgent response that focuses all the strategies and tactics necessary to stabilize the Earth's temperature regime. According to Thomas Jorling, the objective to guide research, development and implementation is straightforward: Achieve an all-electric economy. Simply put, all sectors of…

Purpose: The purpose of this paper is to present a comprehensive analysis of the carbon footprint of the Delft University of Technology (TU Delft), including direct and indirect emissions from utilities, logistics and purchases, as well as a discussion about the commonly used method. Emissions are presented in three scopes (scope 1 reports direct…
