An Investigation into the Models for Financing Renewable Energy Production in Low-Income Settlements in Gauteng, South Africa: A Review

South Africa faces a lack of reliable, modern electricity, essential for economic and social development. Many communities in Gauteng, particularly rural, informal settlements, are not connected to the national grid, leaving 39 percent of the province's residents in darkness and relying on paraffin and gas to survive the cold winters. In addition, these two components increase the number of dead fires in unofficial regulation and the price of electricity camps, increasing the load on the poor. In this study, we surveyed existing literature on the affordable funding model of renewable energy sources, collected primary data in structured industry interviews and stakeholders. This research focused on this survey, focusing on domestic recurring models and analysing the appropriate financing model and financial exhibition source project funding, green finance, public, private partnership, Government subsidies and private investors also instruct foreign investors. Financial procurement model is mixed. In this study, we have developed a framework that allows representatives to link to the outlook of financiers and decision -making, using a mixed methodology approach, and allows you to allow reliable and useful research results. This gap represents a significant obstacle to renewable energy financing. Furthermore, the results indicate that innovative financing channels are needed to promote renewable energy development in Gauteng and South Africa, as traditional financing methods have had little effect in stimulating renewable energy development. Furthermore, the results show that green energy investors consider renewable energy sources to be very risky, even when supported by government policies. Therefore, the study proposes a financing model that brings together funders into small financial consortia to fund local renewable energy projects using a blended financing model. Such a model would spread risk across multiple investors, thereby reducing the potential risks of investments while achieving the goals and benefiting from tax credits and other incentives for investing in renewable energy.

Landscape Design Planning and Research of Renewable Energy Application Projects from a Sustainable Perspective

The substantial emission of carbon exacerbates climate change, posing a threat to human survival and sustainable development. The primary inducement for the carbon emission issue is the excessive dependence of human activities on fossil energy. The construction industry is among the major sectors contributing to carbon emissions, and the low-carbon development within this industry serves as the cyclical engine for the path towards carbon reduction. Currently, there is limited research that integrates low-carbon development with the landscape design of renewable energy projects. Most studies emphasize the application of relevant low-carbon measures, overlooking the landmark effects of building decarbonization. Addressing how to truly achieve landscape design for renewable energy projects from a sustainable perspective based on relevant carbon emission quantification indicators during the architectural design phase is an urgent problem to be solved. This paper takes a sustainable perspective as the starting point and systematically summarizes landscape design concepts from this perspective. It proposes three major design approaches: ecological sustainability, cultural integration, and the application of advanced technology. Using these approaches, the paper tackles the balance between economics, energy, and the environment in landscape design, recognizing it as essentially a high-dimensional multi-objective optimization problem from a methodological perspective. The paper introduces an energy-economy-environment coupling model and utilizes big data. After low-carbon planning and design, both the net carbon footprint and total carbon footprint of the landscape significantly decrease. The Greenfield carbon sequestration per kilogram increases from 301,023.21 to the current 347,856.02, with an increase of 46,832.81.

Application and Impact Assessment of Renewable Energy in Construction Projects

As a new type of environmentally friendly energy, renewable energy is widely used in various fields of society, and its purpose is to reduce the pollution of social production to the environment. For the research on the application effect of renewable energy, there are few cases and insufficient research depth. In order to solve the above problems, this paper proposes an improved regression analysis method, which refers to the construction engineering yearbook of 2020~2022 and the actual construction project as a case for analysis, and compares with SPSS, Mintab and other software to verify the effect of renewable energy application before and after. Among them, the complex data in renewable energy and construction projects are processed by binary classification, and the data with large field spans and low similarity are scaled to improve the unity of research content. The results of the study are realistic: renewable energy has an impact on energy consumption, cost and CO2 emissions in construction projects, and the reduction range is between 10~20%, and there is a positive proportional relationship. At the same time, the application of renewable energy is directly affected by energy policy and environmental policy, and the impact coefficient is between 0.3~0.5. This shows that the application potential of renewable energy in construction projects is huge, and the development sustainability of construction projects is improved.

Determinants of Non-Hydro Renewable Energy Consumption in China’s Provincial Regions

This study investigates the determinants of non-hydro renewable energy (NHRE) consumption across 31 provincial regions in China, spanning from 2015 to 2022. Utilizing fixed effects and moderating effects, the research analyzes the impacts of research and development intensity (RDI), urbanization (UR), and human capital (HC) on NHRE consumption (NHREC). Additionally, the moderating roles of industrial structure (IS) and tax (TA) are examined, along with control variables such as informationization and economic development. The findings reveal that increased RDI significantly boosts NHREC by enhancing technological advancements. UR also positively affects NHREC, particularly in rapidly urbanizing regions, while HC provides a skilled workforce that drives renewable energy projects. However, the study identifies that concentrated industrial structures and high taxes can negatively moderate these positive impacts, highlighting the complex interplay of these factors. Policy recommendations include creating “Renewable Energy Innovation Hubs” in underdeveloped regions to attract startups and researchers, developing “Solar Cities” with mandated solar panels on all buildings, and introducing a “Carbon Offset Lottery” to incentivize investments in renewable energy.

Demand for low-quality offsets by major companies undermines climate integrity of the voluntary carbon market

Most companies include carbon offsets in their net-zero strategy. However, many offset projects are poor quality and fail to reduce emissions as claimed. Here we focus on the twenty companies retiring the most offsets from the voluntary carbon market over 2020–2023. We examine if their offsets could be considered high quality and likely to benefit the climate. We curate an original company-level dataset to examine quality and climate benefits across four dimensions: (1) use of offsets from low/high-risk project types; (2) age of projects and credits; (3) price of credits; and (4) country of implementation. We find that companies have predominantly sourced low-quality, cheap offsets: 87% carry a high risk of not providing real and additional emissions reductions, with most offsets originating from forest conservation and renewable energy projects. Further, most offsets do not meet industry standards regarding age and country of implementation. These findings provide further evidence that the voluntary carbon market is not supporting effective climate mitigation. Particularly, we show that its persisting quality issues are exacerbated by the demand for low-quality offsets by individual companies.

Subsurface storage capacity in structural traps in underexplored sedimentary basins: Hydrogen (H 2 ) and carbon dioxide (CO 2 ) storage on the Irish Atlantic margin

Abstract Methodologies for storage assessment developed for basins with dense data coverage are typically not optimally applicable to underexplored sedimentary basins. To address this, a methodology and workflow for storage assessment in underexplored basins is presented which uses existing datasets to identify structural traps and populate a fluid-in-place equation which can be used for a variety of gases including CO 2 and H 2 . This is then applied to the Irish Atlantic margin; Jurassic, Triassic and Carboniferous reservoirs are investigated to understand their reservoir quality and extent, and related seals. Structural trap types are described and the theoretical capacities of three candidate sites with varying data coverage are calculated. The results highlight the potential for underexplored sedimentary basins on the Irish Atlantic margin to support offshore renewable energy projects and reduce Ireland's CO 2 emissions. This workflow is applicable to a variety of underexplored sedimentary basins and emphasises the utility of legacy hydrocarbon datasets for early-stage subsurface storage assessment. Other aspects of energy storage are also discussed, including man-made salt caverns, other candidate reservoir-seal pairs, and the potential for collaborative infrastructure development with CO 2 emitters and renewable energy projects.

Justice concerns in large-scale renewable energy projects: a case study echoing the importance of procedural justice in wind energy development in Kenya

BackgroundLarge-scale renewable energy projects are increasingly being rolled out across rural Kenya, with the government playing a frontline role in attracting energy investors through various state-led and state-centric policies and investment incentives such as feed-in-tariffs and power purchase agreements. While these policies are commendable, and are indeed attracting many private investors, existing studies document how social and environmental justice concerns are often overlooked—sometimes causing local contestations against energy projects. However, to date, there has been less attention given to cases where procedural justice elements (e.g., access to information, access to meaningful participation, access to justice, and respect for local culture) led to a successful land negotiation for energy development without outright conflict. Using a case study in Kenya, this article aims to bridge this gap by showing how a fair application of various elements of procedural justice in land consultation has facilitated the establishment of the Kipeto wind farm. This qualitative research is based on semi-structured interviews that took place from February to March 2023, with a follow-up visit in December the same year, supplemented with review of secondary data sources.ResultsThe results indicate that for energy projects to be accommodated in and by communities, access to land must be properly negotiated, particularly with the actual landowners whose livelihoods are most likely to be implicated by the project. Second, local people’s perception of what they regard as a ‘just’ or ‘fair’ process of land consultation constitutes the basis for their acquiescence and compliance.ConclusionEnsuring a ‘just’ procedure in land consultation with the actual landowners is a key strategy to avoid conflicts. Land investors, governments, and policy-makers who interface and negotiate with communities must ensure the provision of procedural justice, particularly in contexts where local livelihood is tied to land and where land is individually owned. Although the findings suggest a positive case of wind energy development in Kenya, the project is barely 4 years old; things may change overtime if agreed conditions are not met as specified in the MoU. Therefore, additional follow-up research is needed to ascertain the extent to which both KEL and landowners live up to their promises.

Blockchain-Enhanced Hydrogen Fuel Production and Distribution for Sustainable Energy Management

Renewable energy projects, particularly wind and solar farms, have garnered significant attention as a potential solution to global energy challenges. Despite the energy production obstacles, the steady availability of fossil fuels continues to compete due to established distribution systems, as societies increasingly rely on electricity. Hydrogen fuel emerges as a promising avenue for energy production, storage, and distribution, involving converting surplus renewable electricity into hydrogen through electrolysis, storing it, and distributing it. Our novel approach leverages blockchain technology to enhance the efficiency and traceability of hydrogen fuel production, offering a unique synergy of transparency, security, and decentralized governance. We showcase its viability and effectiveness using the ERC-1155 token standard to tokenize renewable resources and convert them into hydrogen fuel. Within our tokenized fuel blockchain architecture, we simulate the forecasted growth in hydrogen production and vehicle demand, highlighting our approach's efficiency, traceability, and transparency. This integration showcases the potential for a sustainable hydrogen fuel ecosystem. The gas consumption data analysis indicates that the daily gas consumption remains below 194 million Gas for refilling 3245 vehicles (including the cost of one-time contract deployment), demonstrating the feasibility and efficiency of our approach.

An energy transition for all: Investigating determinants of citizen support for energy community initiatives on the island of Mayotte

For an equitable transition towards a decentralized and clean energy future, the involvement and active participation of citizens is needed, exemplified by new organizational forms such as Energy Communities (ECs). While determinants of citizen engagement in renewable energy projects have received some attention in the literature, research mostly focuses on continental Europe, with limited understanding of the perceptions and motivations of citizens living in the Global South or in contexts of poverty and marginalization. Using novel survey data (n = 392) and insights from 16 key informant interviews from the French overseas territory Mayotte, we investigate citizens' perception of renewable energies and ECs and their willingness to participate in such initiatives, confirming high support of the local population for a community-based energy transition. Through exploratory factor analysis and subsequent multivariate regressions, we identify the factors Environmental Awareness, Access to Services and Social Inclusion as important determinants of citizen engagement, with Environmental Awareness exhibiting particularly strong and robust effects on both general support and the willingness to actively participate in an EC. Establishing the housing situation of respondents as a proxy for socio-economic status (SES), we find positive effects of SES on EC support, which is mediated by the identified factors and thereby represents a fourth, underlying determinant of support. Our research underscores the vital importance of considering the multifaceted, diverse perceptions and motivations of the local population to achieve the vision of an equitable transition. Inclusion of needs and priorities of various socio-economic groups, particularly the most vulnerable community members, is essential.

RENEWABLE ENERGY DEVELOPMENT TOWARDS SUSTAINABLE DEVELOPMENT GOALS: A REVIEW IN THAILAND AND THE PHILIPPINES’ LAWS AND POLICIES

Background and Purpose: Renewable energy (RE) plays a significant role in providing sustainable and clean energy as well as mitigating climate change. With the increased energy demand to support the growth of the economic sector, Thailand and the Philippines have moved towards improved energy cooperation, where renewable energy is an important subject matter in line with Target 7 of the Sustainable Development Goals (SDGs). Thailand and the Philippines have embarked on renewable energy projects and introduced numerous laws and policies to incentivise such an agenda. Nevertheless, the contribution of renewable energy in these countries' energy portfolios remains insignificant. Thus, this study aims to examine the current renewable energy laws and policies in Thailand and the Philippines, in assisting these countries to achieve the SDGs. Methodology: This study used a library-research methodology including statutory and conceptual approaches that focus on the laws and policies on renewable energy in Thailand and the Philippines. The utility of conceptual analysis is to understand the concepts and relevance of renewable energy and SDGs in the philosophies of environment, sustainability and law. Findings: Despite the fact RE provides opportunities in respect to socioeconomic development, energy access, energy security, and climate change mitigation, the existence of barriers to RE development leads to obstacles in accelerating RE’s share in the energy mix in Thailand and the Philippines. Comprehensive laws and policies to support renewable energy development are required to address these challenges. Nevertheless, legal frameworks are only one aspect that contributes to RE development. Governments' support through various incentives including financial and economic instruments are critical to navigating the transition toward a cleaner and affordable energy sector. Contributions: This study enhances the body of knowledge by examining the initiative for renewable energy development, advocating for comprehensive legal frameworks, and emphasizing the societal importance of government support to drive RE's role in sustainable development in Thailand and the Philippines.

Measures to combat it will soon focus on modernising technologies to facilitate the transition to the sixth technological paradigm and minimise greenhouse gas emissions. Critical technical solutions may involve harnessing the potential of hydrogen energy and immobilising or preventing greenhouse gas formation technologies. As an alternative direction, the authors consider research to solve some issues related to hydrogen production using metals.

Optimization of renewable energy project portfolio selection using hybrid AIS-AFS algorithm in an international case study

In the coming decade, as restrictions on fossil fuel usage become more stringent, investment in renewable energy projects presents an increasingly appealing opportunity. Evaluating investment attractiveness involves considering both profitability and investment risk. This study proposes a multi-objective mathematical model for identifying the optimal Renewable Energy Project Portfolio (REPP), aiming to maximize net present value while minimizing investment risk. The key innovation of this model is its incorporation of project lifetime and workforce employment considerations to discern the best REPP. To optimize the objective functions of this mathematical model, a hybrid meta-heuristic algorithm combining Artificial Immune System (AIS) and Artificial Fish Swarm (AFS) algorithms is introduced. Genuine data from a varied spectrum of renewable energy projects spanning 20 countries has been meticulously collected. The proposed model is optimized using this dataset, considering portfolio sizes of 3, 5, 10, and 15. The numerical results indicate that, at a specific investment risk threshold, the proposed hybrid algorithm outperforms both AIS and AFS in terms of profitability. Furthermore, the assessment of the geographical distribution of selected projects reveals a deliberate effort to avoid concentration in any specific region, demonstrating a commitment to identifying optimal investment opportunities globally. This research advances the understanding of renewable energy project portfolio optimization, providing valuable insights for investors, policymakers, and sustainable development practitioners.

The utilization of renewable energy and the economic potential of offshore wind power supported by digital finance

Colombia is well-positioned for the development of sustainable energy due to its abundance of natural resources, which include water, wind, and sun. Regulating the safe and sustainable use of offshore wind energy, which is considered non-conventional, is lacking in the nation, nonetheless. The development of offshore wind technology in Colombia shows potential to meet energy needs during dry hydrological conditions and El Niño/Southern Oscillation events when the hydroelectric system power supply is low. This study examines global initiatives that have encouraged nations to develop plans for cutting their CO2 emissions, stressing both their successes and shortcomings in putting offshore wind technology into practice. An examination of Colombia's renewable energy administrative framework finds a lack of data required to carry out offshore wind projects. Furthermore, a review of previous research on marine energy emphasizes how important it is to expand our knowledge of offshore wind generation. Although the majority of local renewable energy projects concentrate on terrestrial sources, an analysis of wind speed and wind power density in Colombia at different altitudes shows promising magnitudes and good trends.Digital finance plays a crucial role in this context by providing innovative funding mechanisms, enhancing financial accessibility, and reducing investment risks through improved financial technologies. These advancements support the mobilization of capital necessary for the development and expansion of offshore wind energy projects.As a result, the technical, economic, administrative, and legal data pertinent to renewable energy in Colombia is compiled in this study. It proposes to provide information to stakeholders involved in decision-making processes and promotes the possible installation of offshore wind farms in regions close to Colombia's Caribbean coast. Because of its plentiful resources, Colombia offers a great chance to implement offshore wind energy technology, which will lessen dependency on fossil fuels and provide a backup energy source in case of supply shortages. The integration of digital finance is key to unlocking the economic potential of these projects, ensuring sustainable and scalable energy solutions for the future.

Integrating Pythagorean Fuzzy SAW and Entropy in Decision-Making for Legal Effectiveness in Renewable Energy Projects

The most important factors must be identified to ensure efficient legal effectiveness for renewable energy projects. However, there are very few studies aimed at determining the most important factors affecting the legal effectiveness of these projects. This situation emerges as a very important gap in the legal effectiveness literature. Accordingly, this study aims to evaluate the most significant indicators of legal effectiveness in renewable energy projects. For this purpose, the main research question of this study is which are the priority strategies to ensure legal effectiveness for these projects. In this scope, four different factors are weighted via Pythagorean fuzzy entropy. Another evaluation was also implemented for the seven emerging (E7) countries in the following process. Within this framework, the Pythagorean fuzzy SAW technique is taken into consideration. The main motivation of this study is the strong need for a comprehensive evaluation to understand the key indicators of the legal effectiveness of renewable energy projects. Hence, the main contribution of this study is the generation of a novel decision-making model to reach this objective. It is concluded that understanding the challenges is the most important criterion. Similarly, defining comprehensive standards also plays a crucial role in this framework. However, developing long-term policies and a fast and fair licensing process have lower significance weights than the others. On the other side, the ranking results denote that Mexico and Russia are the most successful emerging countries with respect to the performance of legal effectiveness. On the other hand, China and Turkey have lower performance in this context.

Exploring the complex interplay of green finance, business cycles, and energy development

Green finance has emerged as a contemporary mechanism to support investments in renewable energy, energy efficiency, and sustainable infrastructure projects. This study aims to provide empirical insights into the asymmetric influence of green finance and business cycle fluctuations on energy development in 60 developing countries from 2000 to 2021. Four aspects of energy development, including energy access, stability, efficiency, and production gap, are examined using panel quantile regression with additive fixed effects. The research findings demonstrate that green finance plays a significant role in fostering energy development, with varying effects across different quantiles of the distribution. Specifically, the results indicate that green finance supports energy access and stability, particularly during economic recession, low-income levels, and limited technological advancement. However, the impact of green finance on energy efficiency exhibits notable heterogeneity, contingent upon technological and periods of economic expansion. Achieving tangible improvements in energy efficiency necessitates a certain level of technological and economic development. Moreover, green finance shows a capacity to maintain an optimal level of energy production, particularly evident during economic expansion and for highly technologically developed countries. The impact of business cycle fluctuations varies across different quantile distributions of energy development indicators, predominantly exerting an inhibitory effect of economic recession. In light of these results, it is recommended that policies in developing countries be revised to enhance energy access, optimize energy production levels, and promote the cost-effectiveness of renewable energy in conjunction with green finance initiatives.

Dual-time scale optimal dispatch of the CSP-PV hybrid power plant considering dynamic operation

The concentrating solar power (CSP) plant, renowned for its flexibility, environmental friendliness, and energy storage capabilities, has become integral components of large-scale renewable energy projects in China. However, the grid connection methods for CSP plants, wind farms, and photovoltaic (PV) plants are independent. To enhance renewable energy consumption and improve the revenue of CSP and PV plants, this paper proposes a dual-time scale dispatch model for the dynamic operation of the CSP-PV hybrid plant. This model considers the actual startup conditions and dynamic switching models of the subsystems involved in the receiver, thermal storage subsystem, and power cycle. Based on the dynamic operation characteristics of the CSP-PV hybrid power plant, different time scales are used for prediction during day-ahead and intraday periods, improving the efficiency of the hybrid power plant and adapting to weather changes. The dispatch optimization outcomes of the CSP-PV hybrid plant serve as the reported curve for the day-ahead and intraday rolling optimal scheduling process, aiming to minimize the operating costs of the power system. A simulation is conducted to demonstrate the effectiveness of the proposed model, utilizing data from the Dunhuang area, Gansu Province, China.
