“…(Simões et al 2011). Currently, they are focused on increasing energy efficiency and RES inclusion, bolstering and broadening their linkage between countries and states (Ponce-Jara et al 2017;Gorjian et al 2021). Despite China being a latecomer to smart grid deployment, its expenditures on smart grid projects mainly focused on high-voltage transmission networks have already surpassed those of the US.…”

Energy transformation and sustainability have become a challenge, especially for developing countries, which face broad energy-related issues such as a wide demand-supply gap, extensive fossil fuel dependency, and low accessibility to clean energy. Globally, smart grid technology has been identified to address these affairs and enable a smooth transition from traditional to smart energy systems, ensuring energy security. This paper studies the critical role in strengthening the power system, integrating renewable sources, electrifying the transport sector, and harnessing bioenergy. Evaluating the current energy scenario in Nepal, this article presents the smart grid as a solution to existing and future energy issues and the associated challenges during its implementation, urging concerned authorities to launch initiatives to promote it. Moreover, this study also lays the foundation for future research into the smart grid's potential to reform the power sector in other developing nations with abundant renewable energy sources and similar energy-related barriers.

“…The exergy of the received solar radiation is defined as the maximum achievable work that could be obtained by utilizing a reversible heat engine between the sun, with the temperature of T s and ambient heat, with the temperature of T a . Since the generated work of a reversible (Carnot) heat engine which works between T s and T a is a function of T a T s [54], this term, and consequently, T s , appear in Equation (7), which is used to determine the exergy of the received solar radiation. More details can be found in [55].…”

“…An affordable solar (photovoltaics (PV)) technology will be of significance in hot-arid developing countries using monocrystalline PV panels [1], which are a reality of transitioning from non-renewable to renewable energy sources [2][3][4]. Some of the absorbed solar irradiation is converted into electricity in a PV module, which operates on the principle of a semiconductor [5][6][7], while the remainder is either dissipated into the surroundings or absorbed by the module itself [8][9][10]. The absorbed energy raises the surface cumulative heat-induced temperature of the PV module, which decreases its output V-I (Voltage-Current) performance [11][12][13][14].…”

Solar irradiation in hot-arid climatic countries results in increased temperatures, which is one of the major factors affecting the power generation efficiency of monocrystalline photovoltaic (PV) systems, posing performance and degradation challenges. In this paper, the efficiency of a water-flow cooling system to increase the output of a monocrystalline PV module with a rated capacity of 80 W is studied from both energy and exergy perspectives. The energy and exergy tests are performed for each season of the year, with and without cooling. The energy and exergy efficiencies, as well as the commodity exergy values, are used to compare the photovoltaic device with and without cooling. The findings are based on the experimental data that were collected in Tehran, Iran as an investigated case study in a country with a hot-arid climate. The findings show that when water-flow cooling is used, the values of the three efficiency metrics change significantly. In various seasons, improvements in regular average energy efficiency vary from 7.3% to 12.4%. Furthermore, the achieved increase in exergy efficiency is in the 13.0% to 19.6% range. Using water flow cooling also results in a 12.1% to 18.4% rise in product exergy.

“…In addition, the devastating environmental consequences of fossil fuel use have exacerbated the situation [ 1 ]. Given the rising trend of world population growth, estimated to increase by more than 9 billion people by 2050, global demand for food will continue to increase, exacerbating the global problem of "food security" as one of the most important components of sustainability [ 2 , 3 ••].…”

Purposeof Review According to the Food and Agriculture Organization (FAO), a large portion of the various activities in the agriculture and food supply chain (AFSC) are extremely dependent on fossil fuels and contribute to 24% of the total global greenhouse gas (GHG) emissions. Recent Findings There are several strategies to reduce GHG emissions and mitigate the associated destructive impacts. Among them, substituting fossil fuels with alternative low-carbon energy sources has received remarkable attention. Summary The core concept of this study is to explore the relationship between food security, sustainable development, and renewable energy. Renewable energy has shown promising potential for integration into a wide range of agricultural activities and offers an alternative sustainable solution to current practices. In modern agriculture, the need for electrification has increased, with electric tractors and agricultural robots accounting for a large share, which represents a great opportunity for the use of renewable technologies in this sector. As new technologies emerge, investors need to familiarize themselves with them. Further technical improvements, cost reductions, and government incentives can facilitate the real-world deployment of sustainable renewable technologies in agriculture and food production.
