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 study finds that optimal placement of long-duration energy storage in renewable-heavy power systems depends on multiple interacting factors—such as generation, demand, storage, and transmission—and cannot be determined by any single metric, with siting decisions having system-wide effects.

Digital Twins for Smart Metabolic Circular Cities, Innovations in Planning and Climate Resilience, Smart Cities, 2025, Pages 115-152

This chapter supports SDG 9, 11, and 7 by discussing the integration of digital twins to enable urban stakeholders to make informed decisions, ensuring that buildings are optimized for both energy efficiency and occupant well-being, thus advancing the goals of sustainable urban development.
This article examines 42,291 renewable energy investment deals across OECD countries from 2004 to 2022, revealing highly international capital flows. Results show that $US 45.4B annually (45%) is invested across borders, with varying degrees between countries. Further, renewable energy investments increasingly mirror general foreign direct investment (89% correlation), indicating financial mainstreaming, which can contribute to rapid deployment.

Community-company collaborations advance renewable energy access through developing and sharing open source technologies for sustainable development.
This study compares traditional Steam Methane Reforming (SMR) and emerging water electrolysis methods (PEMEC and SOEC) for ammonia production, evaluating their economic viability and CO2 emissions under varying electricity prices and carbon intensities. Results show that PEMEC is most cost-effective at very low electricity prices, SOEC gains competitiveness as prices rise, and SMR is preferable above 0.08 €/kWhe, with CO2 emissions depending heavily on electricity carbon intensity; projections indicate SOEC will become highly cost-competitive by 2030–2040.
