“…In order to avoid Fukushima like disaster in future researchers have focused on heat transfer characterization in a pool with submerged heat source under seismic conditions [23][24][25][26][27]. Research related to catching the melted core before it penetrates the reactor building and leading to environmental contamination provide assurance of safety of technology [28][29][30][31][32]. The International Thermonuclear Experimental Reactor (ITER), the largest fusion reactor, is also the subject of intense research to support its capabilities and investigate the underlying physics.…”

Energy is the core of human civilization's development and progress. Global population increase and fast industrialization have led to the imbalanced exploitation of fossil fuels without taking into account their environmental effects. The continuous combustion of fossil fuels, deforestation, and industrial processes has resulted in deterioration of climate. Harmful Greenhouse Gases (GHG) traps the heat leading to an overall rise of earth’s temperature, change in precipitation, and weather events. Climate change poses risk to economies, human societies, and the natural environment. A well-defined urgent measure including the policy changes are needed to be adopted to mitigate its effects. To address this issue, 196 countries agreed to sign the Paris Agreement in 2015, which aims to limit the global reduction in GHG emissions to limit the warming to 1.5 °C above pre-industrial levels. However unique challenges posed by COVID-19 pandemic and slow action of countries is hindering the goals to allow maximum temperature to rise of 1.5 °C by this century (i.e., year 2100). The threat of climate change is real and there is growing recognition among international communities. However, the level of commitment varies across nations and is influenced by a number of variables, including domestic conditions, economic priorities, and political will. Providing accessible and clean energy is a challenge for governments which can be addressed by prioritizing renewable energy investments. Affordable clean energy is crucial for upholding fundamental human rights such as a healthy environment, suitable housing, and access to information. The paper discusses the challenges posed by climate change, role of renewable energy and technological advancements, and necessary actions that are necessary to accomplish the objectives of NZE for our future generations.

“…Despite being limited, conventional energy sources including coal, oil, natural gas, and nuclear power still account for the majority of the energy industry. However, there are other risks connected to nuclear power plants, such as the loss of coolant accident (LOCA) [2]- [5] under unfavourable circumstances. Human beings learned to harness energy from different renewable energy sources, such as solar, geo-thermal, hydro [6], and wind, as time passed [7]- [10].…”

Improvement in heat transfer rate and effectiveness of a solar air heater is always a matter of concern in the scientific community. Different steps have been taken to improve it, including the application of artificial roughness, double glazing, colour coating, and multi-pass flow. In this article, a detailed assessment of the efficiency and effectiveness of a solar air heater has been conducted by applying various types of double-pass arrangements. The effects of various methods applied so far are deeply analysed and discussed to create a better understanding. Future opportunities, challenges, and concerns are also addressed, with a fruitful conclusion in the last. Keywords: Solar energy, solar air heater, double-pass, artificial roughness, thermal performance
