Energy

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.

Hydrogen as a clean, reliable and potentially sustainable energy vector has attracted growing interest for promoting the sustainable development of both industry and society worldwide. Hydrogen is a rising enabler for a multisectorial transition toward a low-carbon economy based on renewable energy sources. Nevertheless, there is a lack of literature scientifically scrutinizing the relationships between a hydrogen economy and the United Nations Sustainable Development Goals.
Transitioning the energy sector to zero or net-zero emission of greenhouse gasses (GHG) and substantially reducing other pollutants is a massive, costly, and long-term effort. The typical starting point and centerpiece of energy decarbonization is the electric power sector. The sector is a large direct GHG emitter. It already has many technological, non-carbon emitting alternatives that are rapidly declining in capital and operating costs and improving in performance, making electricity the least expensive and accessible energy carrier to decarbonize.
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 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.
