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.

In the last couple of years, deep eutectic solvents (DESs) have been raising a lot of attention mainly due to their versatility and their easy and speedy preparation without the need of further purification. Moreover, the vast array of very different compounds that can be selected for their preparation has led to the full tailoring of their relevant properties as solvents.
Rising demand for renewable resources has increased silage maize (Zea mays L.)production characterized by intensive soil management, high fertilizer and pesticide inputs as well as simplified crop rotations. Advantages of renewable biomass production may thus be cancelled out by adverse environmental effects. Perennial crops, like cup plant (Silphium perfoliatum L.), are said to benefit arthropods. Substituting silage maize could hence increase biodiversity and foster ecosystem services.
This Special Issue, bringing together articles from Science of the Total Environment; Renewable and Sustainable Energy Reviews; Ecological Modelling, and Resources; Conservation and Recycling, highlights the increasing understanding that major systems servicing human well-being, food, energy and water (FEW) systems are inextricably connected, and any attempt to address one dimension in isolation of the others will lead to unexpected, undesired, and far from optimal consequences. Considering these three systems holistically as the Food-Energy-Water Nexus directly considers Sustainable Development Goals 2 (zero hunger), 6 (clean water and sanitation), 7 (affordable and clean energy), 9 (industry, innovation and infrastructure), and 12 (responsible consumption and production).
The Sustainable Development Goals and the Paris Agreement, as the two biggest climate action initiatives, address the need to shift towards a fully sustainable energy system. The deployment of renewable energy, especially solar and wind power, decreases carbon dioxide emissions, but presents issues of resource intermittency. In this study, a cost-optimised 100% renewable energy based system is analysed and quantified for the Americas for the reference year 2030 using high spatially and temporally resolved weather data.
This article shows that research in the design of 100% renewable energy systems in scientific articles is fairly new but has gained increasing attention in recent years. In total, 180 articles published since 2004 have been identified and analysed. Many of these articles have a predominant focus on the electricity sector. However, an increasing number of studies apply a cross-sectoral holistic approach on the entire energy system.
Metal halide perovskite materials have revolutionized the solution-processed solar cells and become the vanguard of research focus with an unprecedented improvement of power conversion efficiencies up to 23.3%, which pose a remarkable challenge to thin film and multicrystalline silicon photovoltaics. Nevertheless, for conventional perovskite solar cells based on lead, it is ineluctable to take the toxicity of lead and the long-term stability of the devices into consideration when the deployment of this technology in mass production is put on the agenda.
Falling prices and significant technology developments currently drive an increased weather-dependent electricity production from renewables. In light of the changing climate, it is relevant to investigate to what extent climate change directly impacts future highly weather-dependent electricity systems. Here, we use three IPCC CO 2 concentration pathways for the period 2006–2100 with six high-resolution climate experiments for the European domain.
Key Performance Indicators are important instruments, both in defining high-level goals (international or national) and when planning smart energy communities. However, there is often a gap between the high-level goals, and possible and planned measures on the community level. Evaluation of development scenarios against a defined set of indicators and goals can help urban planners and other stakeholders understand the consequences of their strategies. This article presents a scenario calculator designed to link detailed measures with overall climate goals.
Lithium ion batteries (LIB) continue to gain market share in response to the increasing demand for electric vehicles, consumer electronics, and energy storage. The increased demand for LIB has highlighted potential problems in the supply chain of raw materials needed for their manufacture. Some critical metals used in LIB, namely lithium, cobalt, and graphite are scarce, are not currently mined in large quantities, or are mined in only a few countries whose trade policies could limit availability and impact prices.
This paper examines the potential of energy saving in electrical consumption if the concept of energy-efficient house is implemented in Oman. Energy consumption in the residential sector in Oman was critically analysed and forecasted based on its growth rate and its historical consumption. Then, a base-case validated simulation model for a typical residential dwelling in different cities was generated using a dynamic building simulation software, covering a wide variation of climate conditions in Oman.
