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 run up to COP26, the United Nations Climate Change conference, RELX’s Global Head of Corporate Responsibility, Dr Márcia Balisciano, talks to Prof Trevor Letcher, Prof Carolina Arlota & Prof Hirdan Costa about the energy transition required to meet the Paris Agreement.
Renewable energies have been discussed as the main efficient solution for solving many issues regarding climate change. Statistics said that the share of the building sector is very high in excessive use of fossil fuels. This study aimed to utilize the natural wind to create optimal natural ventilation to achieve thermal comfort of the indoor environment through the best layout and placement of residential blocks, creating proper distance between blocks and orienting blocks properly inside a residential complex site in a summery humid climate.
Urban areas are critical in accomplishing the clean energy transition and meeting the climate goals in the Paris Agreement. The first part of this paper presents a systematic review of scientific publications on zero emission neighbourhoods, positive energy districts and similar concepts of climate friendly neighbourhoods (CFN). The second lists a selection of CFN definitions of public initiatives and research projects. The aim is to identify focus areas, research gaps and future research possibilities.
This article supports SDGs 7 and 9 by introducing interpretable artificial intelligence (AI) tools, especially proxy models based on artificial neural networks, efficient variable analysis and optimal value prediction of membrane electrode components in proton exchange membrane fuel cells, thereby improving their performance and reducing computational costs.

This book chapter addresses SDG 7 by explaining how a stand-alone solar PV/wind hybrid system works including necessary controlling and modeling.
The review examined the potential of renewable and non-renewable energy resources and the current state of exploitation in Kenya.
Heating and cooling in buildings account for nearly 20% of energy use globally. The goal of heating and cooling systems is to maintain the thermal comfort of a building's human occupants, typically by keeping the interior air temperature at a setpoint. However, if one could maintain the occupant's thermal comfort while changing the setpoint, large energy savings are possible.

Nuclear power's contribution to climate change mitigation is and will be very limited. Currently nuclear power avoids 2–3% of total global GHG emissions per year. According to current planning this value will decrease even further until 2040. A substantial expansion of nuclear power will not be possible. Given its low contribution, a complete phase-out of nuclear energy is feasible.
Many inhabited Greek/Mediterranean islands are unsustainable without mainland support due to lack of access to clean water and energy. This case study establishes the feasibility of sustainable green energy solutions for these settlements.
The energy, exergy and economic analysis of indirect type solar dryer (ITSD) was performed while drying green chilli under forced and natural convection. Fans powered by PV panels were used for forced convection setup. The collector and drying efficiencies of the forced convection dryer were found to be 63.3% and 10.4% and the same was 53.84% and 8.90% in natural convection ITSD, respectively. The specific moisture extraction rate (SMER) of green chilli in ITSD was found to be 0.6526 and 0.5603 kg/kW-h under forced and natural convection, respectively.
