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.

California-based Facebook is planning to build two data centres measuring 184,000 square metres in Denmark’s third largest city. This could push up total Danish power demand by a 10%, and accelerate investments in wind production. Increasing the production of wind power and other renewables contributes to the advancement of SDG target 7.2 to increase the share of renewable energy in the global energy mix.
On-site energy storage systems can be used in both domestic and commercial buildings to address the increasing demand on electricity. This would require energy to be purchased at off-peak times and stored for use during peak times. Despite a number of benefits to on-site energy storage systems, they are not yet an economically viable solution, although by 2021 costs are expected to fall significantly. Future-proofing buildings in the form of battery technology supports SDG 7 - affordable and clean energy.
Access to clean and stable energy is a major challenge for many developing African countries. This research aims to investigate ways in which financing renewable energy projects (REPs) can help to address this problem and therefore SDG7. The authors propose the promotion of the two-hand renewable energy service company (ESCO) model as an efficient financial vehicle for increasing sustainable economic development through the production of reliable and stable electricity in semi-urban and rural communities.
This paper addresses the interface of steering, research, and business operators' perspectives to bioenergy sustainability. Although bioenergy business operators are essential for sustainable development of bioenergy systems through implementation of sustainability criteria, their perspective to sustainability is rarely studied.
As part of the transition to a future power grid, distribution systems are undergoing profound changes evolving into Active Distribution Networks (ADNs). The presence of dispersed generation, local storage systems and responsive loads in these systems incurs severe impacts on planning and operational procedures. This paper focuses on the compelling problem of optimal operation and control of ADNs, with particular reference to voltage regulation and lines congestion management.
Energy geotechnics involves the use of geotechnical principles to understand and engineer the coupled thermo-hydro-chemo-mechanical processes encountered in collecting, exchanging, storing, and protecting energy resources in the subsurface. In addition to research on these fundamental coupled processes and characterization of relevant material properties, applied research is being performed to develop analytical tools for the design and analysis of different geo-energy applications.
Studies of waste-to-energy systems have applied a varying range of indicators to assess their sustainability. The sets of indicators prescribed were often based on the respective context and are therefore of varying emphasis. Through a literature review, this research aims to develop a framework of sustainability indicators that can serve as a reference for future research in waste-to-energy systems. Sustainability indicators and their underlying factors from the three pillars of sustainability were consolidated and structured under a proposed framework.

This paper investigates how the notion of 'sustainability' is strategically framed in the context of Dutch infrastructure governance in the Netherlands. By conducting a frame analysis (based on policy documents, websites and semi-structured interviews), the paper discerns six sustainability frames. These frames concern substantive (e.g., more focus on ecology), process (activating new networks) and organizational (e.g., new practices of work) aspects.
Key strategies to low energy buildings
Occupant behavior is one of the major factors influencing building energy consumption and contributing to uncertainty in building energy use prediction and simulation. Currently the understanding of occupant behavior is insufficient both in building design, operation and retrofit, leading to incorrect simplifications in modeling and analysis. This paper introduced the most recent advances and current obstacles in modeling occupant behavior and quantifying its impact on building energy use.

The smart grid's components

The smart grids are modern electric power grid infrastructure for enhanced efficiency and reliability through automated control, high-power converters, modern communications infrastructure, sensing and metering technologies, and modern energy management techniques based on the optimization of demand, energy and network availability. The role of buildings in this framework is very crucial. This paper addresses critical issues on smart grid technologies and the integration of buildings in this new power grid framework.
