Navigating Climate Change and Sustainability Solutions: Nigeria's Role in International Environmental Law

Over the past three decades, the world has witnessed multidimensional impacts of climate change, thus emphasizing the critical urgency for climate action, and promoting sustainability. Africa is reported to disproportionately suffer the consequences of climate change. These consequences such as flooding; droughts and rising temperatures require the adoption of an environmental foreign policy to foster environmental sustainability and cross-sectoral climate resilience. As Africa’s most populous nation and second-largest oil producer significant to global oil supply, Nigeria occupies a unique and distinct position in the global climate discourse. However, despite credibly being a signatory to international bodies such as the United Nations Framework Convention on Climate Change (UNFCCC), Nigeria needs an effective environmental foreign policy to attain the globally desired sustainability and climate resilience. Therefore, this paper delves into Nigeria’s commitment to international environmental law of key international agreements, such as the Paris Agreement, in response to the threatening climate change crisis. The paper recognizes Nigeria as a leading contributor to greenhouse gas emissions in Africa, driving it to develop some national environmental policies that support renewable energy production and sustainability. However, most of the policies seem ineffective. This is because the country needs help with challenges ranging from political interference, corruption, unrealistic emission targets, overreliance on fossil fuels, and other socioeconomic factors. The study highlights the potential of Nigeria, the giant of Africa, in leading regional climate negotiations by localizing international environmental foreign policy and developing a strengthened legal framework to guide the African continent to sustainable development. The perspective of this paper is to encourage Nigeria to meet its sustainability objectives while fulfilling its international environmental obligations by exploring its abundant renewable energy resources such as solar, wind, and hydropower

A simplified rare earth element mining project cost estimator - a new tool for evaluating future mine supply

AbstractRare earth elements (REE) are essential for the future of electric vehicles and renewable energy production, but currently there is limited REE production outside of China. Forecasting global future supplies of REE often relies on the valuation of advanced mining projects to assess if projects will initiate production. Classical valuation methods, such as net present value (NPV), require knowledge of initial capital and operating expenditures to assess the economic feasibility of a given project. Typical industry unit expenditure projections are highly precise but are extremely project dependent and require detailed knowledge of a site that is far beyond the level that a domestic and/or global supply-demand model can obtain. To model future REE supplies we developed a new globally representative, simplified, mining project cost model that can be used to approximate the capital and operating expenditures of greenfield REE mining projects. Results from this model allow users to estimate expenses of open-pit and underground mines with mineral processing operations that range from solely beneficiation to individual REE separation. Using our new model and an estimate of NPV, we evaluate several REE mining projects and assess the economic variables impacting the likelihood for these projects to advance to the production stage. Of 12 assessed projects located outside of China, in the early to advanced development stages, nine had positive NPV at 2011 peak REE prices, but none had positive NPV when prices reached bottom in 2016. Two projects yielded positive NPV’s using 2022 and projected 2028 prices. The viability of these projects given the impact of the volatility in REE prices explains the high uncertainty in the future supply for these mineral commodities.

Empirical Evaluation of The Pollution Haven Hypothesis for Seven Largest Emerging Economies within The Framework of The New Global Climate Agreements

This study aims to determine whether the Pollution Haven Hypothesis (PHavenH), which suggests the negative impact of the FDI on environmental quality (EQ), is valid in seven selected emerging market economies for the period 1990-2020. To achieve this goal, the CO2 emission (CE) model includes renewable energy consumption (REC) in addition to the FDI variable. The elasticity coefficients of the model, in which cross-sectional dependence (CSD) and slope heterogeneity were determined, were estimated by the AMG method. The study found that FDI and REC positively influenced the EQ of the countries examined. The Dumitrescu-Hurlin (D-H) test results indicated a bidirectional causality relationship between FDI and CE. Additionally, a unidirectional causality was observed from REC to CE. These results suggest that both FDI and REC play a role in improving EQ. The results of the analysis show that the PHavenH, which expresses the view that FDI in the relevant countries causes environmental degradation (ED) in developing countries, is not valid. In other words, it confirms the Pollution Halo Hypothesis (PHaloH), which points to the finding that FDI improves EQ in the countries concerned. In this context, it has been concluded that REC has an important contribution to determining the validity of this hypothesis. The findings of the study suggest that it is essential to formulate policy recommendations aimed at boosting the production and utilization of renewable energy in the seven emerging market economies under investigation. Such initiatives can help enhance environmental sustainability and contribute to a cleaner and greener future for these countries.

CAN MASS MEDIA CAMPAIGNS INCREASE DEMAND FOR RENEWABLE ENERGY? EXPERIMENTAL EVIDENCE FROM SENEGAL

Abstract This paper examines public investment in mass media campaigns aimed at stimulating market-led growth within the renewable energy sector in a developing country setting. We run a randomized field experiment to estimate the impact of a large-scale information campaign on the adoption of renewable energy technology, which includes clips broadcasted on national radio and print materials distributed in rural villages in Senegal. While the radio campaign primarily influences the number of renewable energy products owned by existing users (intensive margin), the combination of radio and print significantly increases the number of new adopters (extensive margin). However, when scaled nationally, we calculate a meaningful advantage of the radio clips over the print materials in terms of the cost per additional sales of solar lamps. The study further introduces an innovative methodological approach for examining nationally broadcasted information campaigns, offering valuable insights for future research and policy evaluations.

Beneficial synergetic effect of feedstock characteristics and reaction conditions on bio crude production from hydrothermal liquefaction of mixed residential waste

Hydrothermal Liquefaction (HTL) is a promising method for sustainable waste management and renewable energy production, converting mixed feedstocks into bio-crude, a precursor to various biofuels. A study focused on Mixed Residential Waste (MRW) as an HTL feedstock investigated temperature ranges (280 °C-360 °C) and residence times (30 min–90 min), achieving a maximum bio-crude yield of 39.16% at 340 °C and 75 min. Also, a thorough investigation of the synergistic relationships between all subcomponents of the MRW feedstock was conducted and concluded that the mixed waste (MW) feedstock samples containing a higher proportion of food and plastic wastes and MRW sample presented with a co-liquefaction percentage (CE%) of around 60% and 107% respectively for production of bio crude. Also, solvents such as ethanol, glycerol and aqueous phase (AQ) were tested for their potential as hydrothermal mediums and found that bio crude yield of 46.19% was obtained in case of AQ phase recirculation. Further, the quantitative and qualitative effect of usage of four different catalysts were tested individually and in combination with AQ phase recirculation and found that, although individually Nanoporous ZnO and Diatomaceous Earth (DE) yielded bio crude in the range of 46.86% and 42.68% respectively, when used in combination, DE cat–HTL with AQ resulted in maximum bio crude yield of 54.35%. Furthermore, qualitatively, the bio crude from DE cat–HTL with AQ presented with a high carbon and energy recovery percentage of 62.20% and 72.95% respectively and a high hydrocarbon content of 58.98%.

DFT/TDDFT Investigation of the Effect of Electron Acceptor Groups on Photovoltaic Performance Using Phenothiazine‐Based D‐Ai‐π‐A Dyes for DSSC Applications

AbstractThis review focuses mostly on organic dye‐sensitized solar cells, as they are an attractive, environmentally friendly alternative to traditional silicon solar cells for the production of renewable energy at a lower cost. The dye chromophore is recognized as the central component of the DSSC device. To improve the electrochemical, photovoltaic, and absorption properties of organic sensitizing dyes, we have designed a series of eight new dyes Pi (i = 1.8) based on the DPA‐2 architecture (the reference molecule). We have investigated the effects of internal absorption of different acceptor groups in D‐Ai‐π‐A before and after binding to the TiO2 cluster surface on the ability to inject electrons into the surface. The benzophenothiazine is the D donor, the π‐spacer is furan, and the A acceptor is cycnoacrylic acid. We are using time‐dependent density functional theory (TD‐DFT), and density functional theory (DFT) in our quantum calculations. It is theoretically possible to predict suitable candidates for the DSSC device and identify correlations between their structure and properties by using DFT and TD‐DFT simulations to thoroughly study in detail electronic structures, natural binding orbital (NBO), analysis of UV‐visible absorption spectra, parameters influencing short‐circuit current density (JSC), open‐circuit voltage (VOC), and intramolecular charge transfer (ICT). Additionally, the relationship between optoelectronic properties and molecular structure was investigated, and the effect of auxiliary acceptor groups (Ai) on the primary photovoltaic properties of the reference molecule DPA‐2. The results show that by changing the internal acceptor to DPA‐2 could create a more coplanar and rigid structure. This would cause the energy gap (Eg) for each of the dyes created to significantly shrink, reducing it from 2.29 to 1.38 eV. The absorption spectra's λmax for each dye would also change color, this was because the acceptor moiety Ai of the phenothiazine moiety changed when it came to DPA‐2 (not including compounds P1 and P4). In contrast, P6 and P7 dyes demonstrate an absorption range beyond 500 nm, implying a more efficient utilization of sunlight in the visible spectrum compared to other dyes. Furthermore, all organic dyes show a robust LHE performance (0.919 to 0.993), correlating with the lowest ΔGreg values (0.097 to 0.356) and the most negative ΔGinject values (−2.067 to −1.121). The power conversion efficiency of PCE and JSC could increase according to these results. Therefore, theoretical research into adding a second internal acceptor group to the D‐Ai‐π‐A structure should produce new methods for improving solar energy output.

Design and Analysis of a Vertical Axis Ocean Current Turbine Tunnel Using SolidWorks Computational Fluid Dynamics

The development of renewable energy in the marine power generation sector presents a promising approach to producing electrical energy in a sustainable and environmentally friendly manner. Indonesia, with its vast oceanic territory, holds significant potential for harnessing marine energy. However, the relatively slow speed of ocean currents in the region, typically ranging from 0.1 m/s to 1.5 m/s, poses a challenge to the efficiency of marine power generation. To overcome this limitation, this research focuses on the design and analysis of a vertical-axis ocean current turbine tunnel aimed at increasing the speed of ocean currents, thereby enhancing the overall efficiency of energy production. The study combines a thorough literature review with experimental research methods, utilizing SolidWorks Computational Fluid Dynamics (CFD) software to simulate the tunnel's impact on ocean current velocity. The simulations reveal that the tunnel construction significantly boosts current speeds, increasing them from 1.0 m/s to 1.7 m/s, and from 1.5 m/s to 2.6 m/s. This increase in velocity directly translates to higher kinetic energy available for conversion into electrical power by the turbine. Moreover, the study shows that the tunnel construction contributes to a more uniform flow of ocean currents, as evidenced by the Reynolds numbers obtained—100.250 at a current speed of 1.0 m/s and 150.375 at 1.5 m/s. These values, being below 2000, indicate laminar flow conditions within the tunnel, which are beneficial for optimizing turbine performance by reducing turbulence and ensuring a stable energy output. The findings underscore the effectiveness of the tunnel design in improving the efficiency of vertical-axis ocean current turbines, making it a viable solution for enhancing renewable energy production in regions with low ocean current speeds.

Co-digestion of Sewage Sludge and Biowaste for Biogas Production, GHG Avoided Emissions, and Profitable Carbon Credit Development

In Estonia, where biowaste comprises a significant portion of municipal waste, efficient waste management strategies are essential. Co-digestion presents a promising avenue to enhance biogas yield and reduce greenhouse gas emissions. This study explores the potential of co-digesting sewage sludge and biowaste for biogas production, emphasizing carbon credit calculation and offset project development. Sewage sludge was effectively utilized as a co-feedstock for the co-digestion process, contributing to increased biogas production. In Narva City, 20,401.08037 m3 /year of biogas was produced in 2012, facilitating the generation of electricity from renewable sources and thus reducing GHG emissions, which facilitates the calculation of carbon credits. We developed a robust carbon offset project based on the biogas volume, meeting additionality criteria and demonstrating long-term benefits. The revenue potential from carbon credits ranged from 118 EUR to 41300 EUR, depending on market prices and project attributes. Moreover, the offset project and calculated carbon credits offer tangible benefits to sustainable waste management and the implementation of the circular economy. By valorizing sewage sludge and biowaste through anaerobic digestion, the project contributes to waste diversion from landfills, reduces methane emissions, and promotes renewable energy generation. This integrated approach aligns with principles of sustainable waste management and supports the transition towards a circular economy model. Our findings provide valuable insights for policymakers and stakeholders interested in leveraging anaerobic digestion for renewable energy production and carbon mitigation.

Decision-Making Model Supporting Eco-Innovation in Energy Production Based on Quality, Cost and Life Cycle Assessment (LCA)

Currently, the development of renewable energy products (RES) encourages the search for innovative solutions that take into account key criteria from the point of view of their sustainable development. Despite efforts in this area, there is a lack of approaches and tools to support this process. Therefore, the aim of the research was to develop a decision-making model supporting eco-innovation in products based on the key criteria of sustainable development: quality (customer satisfaction with use), environmental impact in the life cycle (LCA), and the cost of investment incurred in the product development. The functioning of the model was based on the following factors: (i) obtaining the voice of customers (VoC) and processing it into product criteria as part of the development of alternative production solutions (prototypes), (ii) prospective quality assessment and subsequent life cycle assessment of prototypes, (iii) cost analysis taking into account both quality and environmental criteria, (iv) interpretation of results and search for eco-innovative product solutions. Development decision-making is additionally supported by techniques implemented in the model, e.g., the CRITIC method, the LCA method with Ecoinvent database in OpenLCA, the CEA method, and the morphology method. The model was illustrated and tested for photovoltaic (PV) panels, after which a global sensitivity analysis was performed in Statistica. The test results showed that the main factor that influenced the PV development decisions was the investment cost, followed by quality (customer satisfaction) and then environmental impact in LCA.

Policy design for renewable energy development based on government support: A system dynamics model

Energy's centrality to life, work, and progress underscores its indispensable role in modern society. However, burgeoning energy consumption and finite resources have prompted concerns regarding resource sustainability. Consequently, renewable energy sources have gained prominence as alternatives, integral to societal advancement. Therefore, with the increase in the price of fossil fuels and its limitations and the attention to renewable energies, in this research, we decided to study the implementation processes of the development of this type of energy about possible future scenarios and possible implementation policies at the time of each scenario. Let's pay Considering the dynamic complexities of this issue over time and the involvement of government sectors in policy discussions and private sectors in the implementation and participation of these two groups simultaneously, using dynamic system modeling to design a dynamic model that economic aspects, technical, political and environmental aspects should be evaluated simultaneously in a causal-disability manner. To implement this model, two scenarios of government support and non-support for this industry were taken into consideration, and in each scenario two policies of workforce training and technology import for the use of private sector managers and in the best scenario two policies of tax exemption and reduction of technology import tariff for Government decision-making was reviewed. The results showed that when this industry enjoys government support, the speed of development of renewable energy projects can be greatly increased by importing equipment. Without governmental backing, expedited progress is achievable through skilled labor training and employment. Tax exemptions are the most effective policy tool for stimulating renewable energy project processes, production, and sales. The findings underscore the pivotal role of strategic governmental intervention in facilitating renewable energy development, which is essential for meeting energy demands while mitigating environmental impact.

Microplastics in Sewage Sludge: Worldwide Presence in Biosolids, Environmental Impact, Identification Methods and Possible Routes of Degradation, Including the Hydrothermal Carbonization Process

Biomass-to-biofuel conversion represents a critical component of the global transition to renewable energy. One of the most accessible types of biomass is sewage sludge (SS). This by-product from wastewater treatment plants (WWTPs) contains microplastics (MPs) originating from household, industrial and urban runoff sources. Due to their small size (<5 mm) and persistence, MPs present a challenge when they are removed from sewage systems, where they mainly accumulate (~90%). The presence of MPs in SS poses environmental risks when biosolids are applied as fertilizer in agriculture or incinerated for the purpose of energy production. The key problem is the efficient and reliable identification and reduction of MPs in sewage systems, due to the lack of standardized procedures. The reduction methods for MPs might involve physical, chemical, biological, and hydrothermal approaches, including hydrothermal carbonization (HTC). The HTC of SS produces hydrochar (HC), a solid biofuel, and presents a cutting-edge approach that simultaneously addresses secondary microplastic pollution and renewable biomass-derived energy production. In this article, we review briefly the MPs content in biosolids from different countries, and present HTC as a promising method for their removal from SS. In conclusion, HTC (i) effectively reduces the abundance of MPs in biosolids, (ii) produces an improved solid source of energy, and (iii) contributes to circular SS management.

Energy comparison and cost estimation of pressure-retarded osmosis using spiral wound membrane

Advancements in Pressure Retarded Osmosis (PRO) technology are enhancing the feasibility of evaluating its economic viability against other renewable energy production methods. This is done using the Levelized Cost of Energy (LCOE) as a metric. The study focuses on three PRO scenarios designed to minimize environmental impact and promote sustainable energy. These scenarios utilize a spiral-wound membrane module combined with hyper-saline solutions from Reverse Osmosis (RO) and wastewater from demineralization processes. Experimental results using a commercial spiral-wound membrane in the PRO system yielded LCOE values of USD 0.0702/kWh for a draw solution (DS) concentration of 36.2 g/l, USD 0.0563/kWh for 44.2 g/l, and USD 0.0721/kWh for 51.8 g/l. The study also evaluated environmental viability by considering the cost of CO2 emissions. This comprehensive comparison highlighted PRO's competitiveness with fossil fuels, showing it to be a reasonable alternative to coal and oil but less practical than natural gas. Specifically, the environmental analysis revealed that PRO is approximately 25.2 % more competitive than coal and 9.76 % more competitive than oil but 27.16 % less competitive compared to natural gas in terms of CO2 emission costs. This underscores the importance of considering carbon emission mitigation in energy generation.

Strategic Siting of Hydroelectric Power Plants to Power Railway Operations with Renewable Energy

The present study explores the strategic siting of hydroelectric power plants, focusing on the Miyanaka Intake Dam (MID) and Shinano River Hydroelectric Power Station (SHP). Built in 1939 to support Tokyo’s railway electrification, these facilities demonstrate the complexities of balancing renewable energy production with ecological conservation. Despite the high costs and energy losses associated with transmitting power from the Sea of Japan side, the SHP has effectively powered Tokyo’s rail system for over 80 years, owing to advanced transmission technologies and the region’s abundant water resources. However, river-crossing structures such as dams disrupt fish migration and habitats, necessitating the implementation of fishways. The MID fishway, continually improved since its construction, emphasizes the importance of integrating ecological considerations into hydropower projects. Our findings highlight the higher power generation efficiency on the Sea of Japan side and stress the need for careful site selection to ensure sustainable hydroelectric power while preserving river ecosystems. In conclusion, hydropower sites should be chosen based on both environmental impacts and future development potential to maintain the ecological balance and support long-term renewable energy goals.

Impact of psychological distance on public acceptance of waste-to-energy combustion projects

Waste-to-energy (WTE) projects have attracted considerable attention due to their role in addressing waste management issues and promoting renewable energy production. However, while public acceptance of these projects remains controversial, psychological distance (PD) may be a key shaping factor in their construction. This study, grounded in the Construal Level Theory (CLT) and social distance theory of power, uses a behavioral investigation experiment to examine the role of PD in WTE facilities. The findings reveal that shorter PD is associated with higher public perception of risk and lower perception of economic benefits, fairness, and public acceptance. Additionally, a closer social distance of power tends to correspond with lower construal levels and a greater inclination to support the construction of WTE facilities, further supporting the CLT and social distance theory of power. The findings provide theoretical support and practical guidance for the sustainable development of WTE facilities, encouraging a sense of shared destiny and collaborative governance across society.

Green Synthesis of carbon quantum dots for enhancing photocatalytic activity: Hydrogen/oxygen evolution and dye photodegradation

Carbon quantum dots (CQDs) have recently attracted attention across various fields due to their small size, high conductivity, fluorescence emission, low toxicity, and other desirable characteristics. In this study, highly fluorescent CQDs with an average diameter of 3.7 nm were prepared via microwave irradiation using a standard commercial microwave oven and glycerol as solvent. Several cation promoters were examined for CQD synthesis, with copper ions ultimately chosen for comprehensive characterization and application. The CQDs were impregnated onto both commercially available and microwave-synthesized TiO2 nanoparticles. The photocatalytic activity was evaluated with respect to the hydrogen and oxygen generation. Under the employed conditions, the oxygen evolution reaction (OER) exhibited over 12 times higher efficiency than the hydrogen evolution reaction (HER). The enhanced OER activity is attributed to the high electronic conductivity of the small Cu doped CQDs@TiO2 (Cu-CQDs@TiO2) facilitating an efficient electron transfer for the OER . Visible light activity (λ ≥ 400 nm) was demonstrated by photodegradation of the indigo carmine (IC) solution used as a model pollutant. Irradiation in the presence of the Cu-CQDs@TiO2 photocatalyst resulted in complete degradation of the dye in less than 3 hours. The results presented here provide a promising methodology for designing high-performance photocatalysts based on environmentally friendly CQD syntheses. Crucial applications, from renewable energy production to environmental remediation, will benefit from strategies using the carbon abundance on Earth.

Rare earth metallic elements in plants: assessing benefits, risks and mitigating strategies.

Rare earth elements (REEs) comprises of a uniform group of lanthanides and scandium (Sc) and yttrium (Y) finding their key importance in agriculture sectors, electronic and defense industries, and renewable energy production. The immense application of REEs as plant growth promoters has led to their undesirable accumulation in the soil system raising concerns for REE pollution as upcoming stresses. This review mainly addresses the chemistry of REEs, uptake and distribution and their biphasic responses in plant systems and possible plausible techniques that could mitigate/alleviate REE contamination. It extends beyond the present understanding of the biphasic impacts of rare earth elements (REEs) on physio-biochemical attributes. It not only provides landmarks for further exploration of the interrelated phytohormonal and molecular biphasic nature but also introduces novel approaches aimed at mitigating their toxicities. By delving into innovative strategies such as recycling, substitution, and phytohormone-assisted mitigation, the review expands upon existing knowledge of REEs whilst also offering pathways to tackle the challenges associated with REE utilization.

Economic and strategic challenges in microgrid integration: Insights from operational dynamics and renewable energy potential

With the integration of a large number of microgrids in the power distribution network operation, economic and strategic challenges arise. To address these challenges, this research provides a comprehensive investigation into the operational, economic, and strategic dynamics of microgrids. Through careful data analysis, the study interprets the complications of microgrid responses to seasonal changes. It also investigates energy consumption patterns and production dynamics. The detailed analysis of microgrid configurations reveals the unique attributes and challenges of PV, wind, and hydropower microgrids. Moreover, the research explains the financial implications of microgrid integration, from setup costs to potential ROI. It is also examining the cooperative relationship between microgrids and conventional grids. Key findings highlight that solar microgrids contribute 3.2% to 5.3%, wind microgrids provide 5.9% to 7.4%, and hydropower microgrids contribute 24.4% of total power. Energy purchase peaks at 850,000 kWh in August and declines to 580,000 kWh in May. 170,000 kWh of energy is sold back to the grid in May. Moreover, the grid energy costs reduced from $0.178 kWh to $0.30 kWh. The total net present cost of the system is achieved at $37,880,023.33. Renewable energy production ranges from 480 kW to 2,300 kW, with a penetration level reaching 160%.

Treating produced water - crude oil emulsion using concentric packed UV- bioelectrochemical cell (CPUBEC)

This research paper comes in the context of the growing global scientific path to develop clean renewable energy production methods that are commensurate with the required environmental standards, reduce carbon emissions, and treat pollutants in the water produced with the production of crude oil from oil fields, which are large quantities and are constantly increasing with the growing global demand for oil and gas. A bioelectrochemical cell was manufactured from available capacitive materials (GQDs/TiO2) with biofilm spread in the parts that are not directly exposed to UV ray in an innovative installation consisting of a cylindrical shell with spherical packing anode and a cathode in the middle of membrane that separates the tow electrodes. Both electrodes are arranged in a Pyrex pot and connected to external resistance. The packed cell (with and without uv-ray) performance was compared with unpacked cell to determined the effect of the packing and UV ray by studying the efficiency of removing pollutants TPH and COD. the best results in the packed cell with UV ray as follows:97.1 %, 97 % respectively, while the best results obtained in the case of using an unpacked cell was 86.6 %, 84.8 %. the change in the pH during the operating cycle was also studied and it was found that the change in the packed cell was slightly greater than the change in the unpacked cell as a result of the complex interactive on the surface of the anode. The highest current density produced was 1316 mA/m2 on the fifth day in packed cell and presence of UV ray.

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.

English Translation of New Vocabulary for Text Analysis of New Energy Industry and International Evaluation of Power Quality

With the advancement of global energy transformation, the rapid rise of the new energy industry has become a strategic highland that countries are eager to seize. The inherent instability and unpredictability of renewable energy production pose significant obstacles to the seamless operation of the power system. To address these challenges, this article employs text analysis, data-driven methods, and artificial intelligence technology in neologisms to conduct an in-depth international evaluation and comparative research on the power quality of the new energy industry. Using text mining techniques to conduct an in-depth analysis of new energy policy texts in various countries, revealing their policy characteristics and trends. At the same time, the combination of data-driven and artificial intelligence technology enables more accurate prediction and decision analysis. Based on the findings of this study, the United States has achieved a significant 35% enhancement in the quality of new energy electricity over the past decade, attributed to its consistent monitoring and improvement initiatives. Meanwhile, Germany, owing to its robust monitoring system, has witnessed a 25% improvement in electricity quality in the last five years. However, in developing nations like India and Brazil, approximately 60% of new energy projects encounter challenges related to grid connectivity and scheduling, resulting in a deterioration of electricity quality. In contrast, only 20% of developed countries have issues with grid access and scheduling. This phenomenon reflects that developing countries still need to increase investment and improve the layout of new energy industries and the construction of power grid infrastructure. Developing countries should actively learn from the successful experiences of developed countries in the new energy industry and power grid construction, formulate appropriate policy measures based on their national conditions, improve the quality of new energy electricity, and promote energy transformation and sustainable development.
