Rapid growth in the global population and associated elevated reliance on modern technology has resulted in increased demand for energy consumption. This has resulted in an increased focus on the development and generation of advanced sustainable energy systems. The swift implementation of sustainable renewable energy resource utilization and improvement in their efficiency by the modification of current technologies are the possible solutions that gave rise to the emergence of geothermal technology as a potential alternative. Geothermal technology is a non-carbon renewable energy resource that could be utilized efficiently to fulfil the energy demands while mitigating the climate change threat. According to the surveyed literature, the global geothermal energy power plant installation capacity has reached 14.3 GWe to successfully implement this sustainable alternative. In order to have a successful and uninterrupted way forward, it is essential to evaluate the constraints both in terms of technicality and economic feasibility to establish an approved framework. Moreover, the governance and monitoring regarding the social and environmental impact alongside the legal challenges should also be addressed. The significant barriers include increased capital cost, site selection, superiority of resources at diverse levels of rock bottoms, and obstruction from nearby residents that need to be addressed appropriately. As a result, policymakers will continue to seek measure that have least negative impact on environment. [ABSTRACT FROM AUTHOR]

India's commitment to renewable energy has been reinforced through its ranking as the fourth-largest global solar power capacity holder, as reported in the Ministry of New and Renewable Energy's 2022 year-end review. Non-fossil fuel-based power generation has reached 42.26% of India's total installed capacity. In this context, solar pump installations for agricultural use, under the component – A, B, C, are in progress. This study proposes the deployment of stand-alone solar power plants using the System Advisor Model (SAM) in three distinct regions of Andhra Pradesh, India. Aimed at facilitating the adoption of green energy and income generation through surplus power sales in rural communities, this work is grounded in a comprehensive survey conducted across eight diverse locations: Ganayigudem, Manduru, Jogannapalem, Vegavaram, Veeravallipalem, Ainavillilanka, Seetharampuram, and Naguladevupadu. Real-time power requirement data was collected from 112 farmers across approximately 882 acres of land. These locations were divided into three sets, designated as set-A, set-B, and set-C, using a clustering approach. The energy requirements for agricultural purposes were derived from the survey data, enabling the near-practical construction of a solar plant via the SAM software, using actual weather data and load requirements. The Levelized cost of energy nominal (LOCE) was calculated to be 3.38 $/kWh and 2.7 $/kWh per cent of land area for set-A, 3.18 $/kWh and 2.54 $/kWh for set-B, and 3.33 $/kWh and 2.66 $/kWh for set-C. These figures encapsulate the cost of constructing and maintaining the solar plant over its lifespan. The lower LOCE for set-B compared to set-A is attributed to the larger plant size in set-A. The feasibility of solar plant construction is enhanced by government-provided tax benefits. However, it is noteworthy that changes in weather patterns may introduce slight discrepancies in practical implementation, as the current results are based on past weather data.

This paper is the editorial of the VSI (virtual special issue) of Applied Energy (APEN) dedicated to the 18th Conference on Sustainable Development of Energy Water and Environment Systems (SDEWES) held in 2023, from September 24th to 29th in Dubrovnik, Croatia. The VSI, after a rigorous pre-screening among the more than 600 submissions, around 40 authors were invited to submit the extended version of their work to Applied Energy with a final number of 14 published articles. Sustainable Energy Systems are explored by the authors of those papers from different perspectives by presenting innovative and cutting-edge solutions. [ABSTRACT FROM AUTHOR]

This paper is the editorial for the virtual special issue (VSI) of Renewable and Sustainable Energy Reviews (RSER) dedicated to three Sustainable Development of Energy Water and Environment Systems (SDEWES) Conferences held in 2022, namely: (i) the 5th South East European Conference SEESDEWES 2022 held from May 22 to 26, 2022 in Vlore, Albania; (ii) the 3rd Latin American LASDEWES 2022 held from July 24 to 28, 2022 in Sao Paulo, Brazil and (iii) the 17th SDEWES 2022 held from November 6 to 10, 2022 in Paphos, Cyprus. The VSI collected both high quality review papers and original research articles presented at these conferences, aligning with the aims and scope of RSER. Following a rigorous peer review process, seventeen articles were accepted and published. These articles explore techniques and technologies essential for advancing feasible Renewable and Sustainable Energy Systems. Spanning multidisciplinary topics, many of them address almost all the Sustainable Development Goals, offering feasible solutions for much-needed decarbonization pathways. • The VSI SDEWES 2022 presents the ready solutions for Renewable and Sustainable Energy Systems. • Five clusters for presenting the Renewable and Sustainable energy cutting edge solutions. • The positioning in the scientific context of the Renewable and Sustainable Energy Systems. • Feasible solutions for much-needed decarbonization pathways.

Mounting energy consumption and increased concern over the financial and ecological repercussions necessitate the implementation of renewable energy technology in India. Renewable energy sources have experienced a variety of challenges, which shows their growth level. Given its extensive population and finite fossil fuel reservoirs, India stands at a significant opportunity to excel in renewable energy forms like wind, solar, geothermal, hydro, biomass, and tidal energy. The objective of this study is to recognize and evaluate the barriers hindering the adoption of renewable energy technology and to prioritize the various renewable energy sources prevalent in India. An exhaustive literature analysis has revealed 21 barriers, which were classified into five categories: economic, technical, social, environmental, and political. The existing literature rarely addresses tidal energy and political barriers, both of which are explored here. Additionally, this research integrates fuzzy data. As fuzzy sets allow partial membership in contrast to crisp sets, this offers enhanced flexibility. Graph Theory and Matrix Approach is utilized for ranking the renewable energy sources with the help of matrix permanent in fuzzy environment. Furthermore, a sensitivity analysis is performed to evaluate the consistency of the sequence of importance. The case study reveals that among the alternatives, wind energy holds the highest permanent value, followed by solar and biomass energy, with tidal energy having the lowest value. This indicates that, considering the barriers, wind energy is the most preferred renewable energy source in India, followed by solar and biomass energy. The outcomes might be applicable to numerous developing countries with similar technological and technical limitations. Moreover, this comprehension could prove valuable in formulating policies and strategies aimed at embracing renewable and sustainable energy technologies. [Display omitted] • A fuzzy GTMA approach is proposed for ranking renewable energy sources (RES). • Finalize 21 barriers to adopting RES from the literature and expert opinion. • Rank the RES based on the impact of the barriers to adopting them in India. • Perform sensitivity analysis to check the consistency of the order of importance. • Managerial implications and suggestions are provided as research direction.

Based on representative firm-level survey data for Austria, Germany, and Switzerland, this study systematically analyses the relevance and drivers of barriers to green product innovation using the example of green energy technologies. 'Low willingness to pay', 'high development costs', 'high commercial uncertainty', and 'lack of favourable political framework' are identified as the most important barriers. Moreover, we find that the firms' innovation experience is an important driver of the level of green innovation barriers. Green innovation barriers are more accentuated for firms with green innovation activity than for firms with no green innovation activity. However, experience from different fields of green innovation and experience from non-green innovation activities help to limit these barriers. [ABSTRACT FROM AUTHOR]
