In the contemporary period of the green economy, energy planning has grown more complicated due to the inclusion of numerous standards, including technical, social, economic, and environmental. This, in turn, restricts the ability of decision-makers to make the most efficient use of energy resources. In addition, the difficulty of energy planning is exacerbated by topographical restrictions on renewable energy systems, the majority of which are found in nature. Based on factors such as total installed capacity, total reservoir capacity, total surface capacity, the height, length, number of units, and the cost of the dam were used to determine the finest hydro power project in India, according to this study. For performance evaluation, multi criteria decision making (MCDM) techniques like analytic hierarchy process (AHP) and TOPSIS (technique for order reference by similarity to ideal solution) are used in conjunction with VIKOR (vlekriterijumsko kompromisno rangiranje) for performance evaluation. AHP is used to calculate the weights of each criteria. The TOPSIS and VIKOR methods will utilise these weights to choose the optimal option. For the purpose of demonstrating the approaches’ applicability, an in-depth case study of various hydropower facilities in India was carried out.

Agriculture is the primary source of food production for humankind. The drastic increase in the global population is paving the way to directly increase the food productivity creating enormous pressure on the agriculture sector. The demand for food production is increasing rapidly every day across the globe. According to the UN world population index, the world population is expected to reach 9.7 billion by 2050. Doing traditional conventional farming will not be sufficient for the production and catering to the needs of 9.8 billion people. We are now shifting from conventional traditional farming to new advanced precision farming methods to meet the demand. The introduction of the Internet of things (IoT) into the agriculture sector has changed the dynamics of the sector. The IoT based devices are mainly proving to be efficient in giving a high performance with low energy usage. IoT based devices automatically monitor and maintains agricultural farms reducing the minimal use of human involvement. This article mainly highlights the recent IoT based products and their usage in the agriculture sector. The public and private projects across the globe which provide feasible growth in the agriculture sector are discussed. Further, this article discusses the use of unmanned aerial vehicles (UAV) and their applications in the agriculture sector. After a thorough review of the future of IoT in the agriculture sector, its Applications, challenges, research potential and limitations are briefly discussed.
