Energy

Energy is a central component of the United Nations' Sustainable Development Goals (SDGs), explicitly reflected in SDG 7: Affordable and Clean Energy. However, the theme of energy cuts across multiple SDGs, demonstrating the interconnectivity of these global goals.

SDG 7's objective is to ensure access to affordable, reliable, sustainable, and modern energy for all. Energy, in its various forms, is a vital driver of economic growth and is pivotal to nearly all aspects of development. Without a steady and reliable supply of energy, societies can hardly progress. However, millions of people around the world still lack access to modern and clean energy services. The emphasis on "affordable and clean" energy within this goal shows the need to transition from traditional energy sources, often characterized by high environmental costs, to more sustainable ones like wind, solar, and hydropower.

Energy's role is also significant in achieving other SDGs. For example, SDG 9: Industry, Innovation, and Infrastructure, emphasizes the need for sustainable and resilient infrastructure with increased resource-use efficiency and greater adoption of clean technologies. It is almost impossible to achieve this without a sustainable energy framework. Similarly, SDG 11: Sustainable Cities and Communities, calls for making cities inclusive, safe, resilient, and sustainable, and one of its targets (11.6) directly refers to the environmental impact of cities, for which energy is a key factor.

Furthermore, energy is a crucial player in SDG 13: Climate Action. The energy sector represents the largest single source of global greenhouse gas emissions. Transitioning to a sustainable energy future, therefore, is critical for tackling climate change. Efforts to reduce emissions and promote clean energy sources are crucial to mitigate climate change and its impacts.

This book chapter advances SDGs 13 and 7 by introducing the role of project finance in a renewable energy infrastructure.
This book chapter advances SDGs 13 and 7 by explaining the basics of power markets as well as the future of energy markets.
The two-dimensional (2D) ultrathin Mg-Al layered double hydroxide modified by magnetic Fe3O4 (Fe3O4/Mg-Al LDH) was successfully synthesized via the co-precipitation method. The Fe3O4/Mg-Al LDH not only exhibits superior separation efficiency of charge carriers but also possesses signally enhanced photocatalytic activity for CO2 reduction than Mg-Al LDH. The as-prepared Fe3O4/Mg-Al LDH affords the CO and CH4 generation rate of 442.2 µmol g−1 h−1 and 223.9 µmol g−1 h−1. The enhanced reduction CO2 activity mainly comes from synergetic effect of Fe3O4 and ultrathin Mg-Al LDH.
The question of how to enable an effective, modern, global energy transition is garnering significant interest in both academic and policy making communities. Composite statistical indices have emerged as a useful class of tools to offer policymakers additional insights into the state and trajectory of energy transitions around the world. In this commentary, we discuss the purpose of energy indices in general and document several prominent examples. We then introduce and place in this landscape the World Economic Forum's Energy Transitions Index (ETI).

As global temperatures continue to rise, questions about infrastructure capacity to keep up with energy demand are increasingly germane. Energy demand is mediated by several structural and environmental conditions, though we have a limited understanding about the role of differences in local ambient temperatures as a predictor for energy demand. This study assesses the effects of residential building structure, socio-demographics, and ambient temperature conditions of a neighborhood to overall energy expenditures of a household.

This white paper examines whether ambitious renewable targets and private sector financing is compatible in Europe over the next decade. It directly relates to SDG 7 - affordable and clean energy, and SDG 13 - climate action.
This book chapter addresses goals 7, 12, 13 and 14 by describing the fundamental issues of microalgae and their cultivation as a biofuel and alternative food source.
Soiling consists of the deposition of contaminants onto photovoltaic (PV) modules or mirrors and tubes of concentrated solar power systems (CSPs). It often results in a drastic reduction of power generation, which potentially renders an installation economically unviable and therefore must be mitigated. On the other hand, the corresponding costs for cleaning can significantly increase the price of energy generated. In this work, the importance of soiling is assessed for the global PV and CSP key markets.
Agricultural wastes are readily available in farming communities and can be utilised for off-grid electrification as an alternative to diesel generators. This work evaluates for the first time the life cycle environmental sustainability of these small-scale systems in the context of Southeast Asia. Rice and coconut residues are considered for direct combustion and gasification, and livestock manure for anaerobic digestion. Overall, anaerobic digestion is the best option for 14 out of 18 impacts estimated through life cycle assessment.
Electricity systems based on renewables have an increasing demand for flexibility. This paper considers the potential of power-to-gas to provide flexibility and enhance system integration of renewables. Existing research on power-to-gas typically analyses the system effects of a predetermined power-to-gas unit without endogenising the investment decision. Moreover, insights related to market and portfolio effects of power-to-gas are rare. To this end this work presents a stochastic electricity market model.
