This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:
"For decades they’ve taken a backseat to their mineral counterparts. But today, organic materials are booming—not least of all for their applications in lithium-ion batteries. A new review article published in the journal ChemPlusChem discusses how one class of organics in particular is poised to yield high performance from a tiny but versatile package: carbonyl-based π-conjugated compounds. Like other organic materials, carbonyl-based π-conjugated materials present a unique and much-needed solution to the global energy crisis. Flexible, light, and naturally abundant, these compounds offer the prospect of nimble energy-storage systems with energy and power densities comparable to inorganic systems. What sets carbonyl-based π-conjugated materials apart from other organics is highly tunable electrochemical performance stemming from a versatile starting structure. The redox mechanism of carbonyls proceeds by a reversible one-electron reduction to form a radical mono-anion and the reverse reaction..."

This video lesson aims to motivate students about chemistry and to raise their awareness about how chemistry helps in solving certain environmental problems. In this lesson, the air pollution problem created by cars and other vehicles is presented. The lesson will highlight causes of this problem, harmful products from it and possible solutions. There will also be discussion of ways to convert the pollutants produced by burning oil in vehicles into more friendly products.

D-Lab: Energy offers a hands-on, project-based approach that engages students in understanding and addressing the applications of small-scale, sustainable energy technology in developing countries where compact, robust, low-cost systems for generating power are required. Projects may include micro-hydro, solar, or wind turbine generators along with theoretical analysis, design, prototype construction, evaluation and implementation. Students will have the opportunity both to travel to Nicaragua during spring break to identify and implement projects. D-Lab: Energy is part of MIT’s D-Lab program, which fosters the development of appropriate technologies and sustainable solutions within the framework of international development. This course is an elective subject in MIT’s undergraduate Energy Studies Minor. This Institute-wide program complements the deep expertise obtained in any major with a broad understanding of the interlinked realms of science, technology, and social sciences as they relate to energy and associated environmental challenges.

This course is an introduction to power electronics. First the principles of power conversion with switching circuits are treated as well as main applications of power electronics. Next the basic circuits of power electronics are explained, including ac-dc converters (diode rectifiers), dc-dc converters (non-isolated and isolated) and dc-ac converters (inverters). Related issues such as pulse width modulation, methods of analysis, voltage distortion and power quality are treated in conjunction with the basic circuits. The main principles of operation of most commonly used power semiconductor switches are explained. Finally, the role of power electronics in sustainable energy future, including renewable energy systems and energy efficiency is discussed.
Study Goals To get acquainted with applications of power electronics, to obtain insight in the principles of power electronics, to get an overview of power electronic circuits and be able to select appropriate circuits for specific applications and finally to be able to analyse the circuits. The focus in the course is on analysis and to a lesser extent on design.

With increasing public awareness of the multiple effects of global environmental change, the terms water, energy, and food crisis have become widely used in scientific and political debates on sustainable development and environmental policy. Although each of these crises has distinct drivers and consequences, providing sustainable supplies of water, energy, and food are deeply interrelated challenges and require a profound understanding of the political, socioeconomic, and cultural factors that have historically shaped these interrelations at a local and global scale.

Our world runs on energy - without it, things come to a screeching halt, as the recent hurricanes have shown. Ever stop to wonder what our energy future is? What are our options for energy, and what are the associated economic and climatic implications? In \Energy and the Environment\" we explore these questions, which together represent one of the great challenges of our time - providing energy for high quality of life and economic growth while avoiding dangerous climate change. This course takes an optimistic view of our prospects, and we'll see how shifting to renewable energy can lead to a viable future.

How can we, as youth, build a sustainable future while meeting the energy needs of today? The Path to Sustainable Energy (PaSE) curriculum explores sustainable energy as students investigate place-based energy resource and consumption issues, gather resources, and build leadership skills to identify and take action on shared challenges and impacts of energy usage.

This course examines the interconnections of international politics and climate change. Beginning with an analysis of the strategic and environmental legacies of the 20th Century, it explores the politicization of the natural environment, the role of science in this process, and the gradual shifts in political concerns to incorporate “nature”. Two general thrusts of climate-politics connections are pursued, namely those related to (a) conflict – focusing on threats to security due to environmental dislocations and (b) cooperation – focusing on the politics of international treaties that have contributed to emergent processes for global accord in response to evidence of climate change. The course concludes by addressing the question of: “What Next?”

Students learn about the basic principles of electromicrobiology—the study of microorganisms’ electrical properties—and the potential that these microorganisms may have as a next-generation source of sustainable energy. They are introduced to one such promising source: microbial fuel cells (MFCs). Using the metabolisms of microbes to generate electrical current, MFCs can harvest bioelectricity, or energy, from the processes of photosynthesis and cellular respiration. Students learn about the basics of MFCs and how they function as well as the chemical processes of photosynthesis and cellular respiration

The main objective of this video lesson is to bring the students' attention to the importance of basic and natural sciences in our lives. The lesson will introduce a topic (sustainable energy) that is related mainly to chemistry and is not usually covered directly in a high school curriculum. We hope that this lesson will show students how important and useful the natural and basic sciences are not only for our daily lives, but also for sustainable development. The lesson will present creative and challenging ideas on the topic of alternative energies. It is hoped that students will be inspired by the introduction of these ideas, and that they will develop the confidence to come up with creative ideas themselves. Background for this lesson is based on fundamental concepts in chemistry (mainly), biology, physics and environmental science.

A transition to sustainable energy is needed for our climate and welfare. In this engineering course, you will learn how to assess the potential for energy reduction and the potential of renewable energy sources like wind, solar and biomass. You’ll learn how to integrate these sources in an energy system, like an electricity network and take an engineering approach to look for solutions and design a 100% sustainable energy system.
