Shortage and environmental threats posed by fossil fuel have become a critical issue requiring searching for alternative energy sources. This study utilized clay-doped barium chloride ionic liquid (CD-BaCl-IL) as catalyst optimizing biodiesel production from shea butter. 10% were blended with clay, dried, then calcined 4 h at 600 °C to develop the catalyst. The synthesized suitably characterized. Response surface methodology (RSM) implementing Central Composite Design (CCD) Genetic Algorithm (GA) employed model optimize effect of process parameters on response. model's capabilities evaluated using coefficient determination (R2) mean square error (MSE). second-order polynomial is shown in Analysis Variance (ANOVA) an (R2 -0.9945, Adjusted R2-0.9846, Predicted R2-0.8694) demonstrating acceptance. Artificial Neural Network (ANN) Adaptive Neurofuzzy Inference System (ANFIS) used assess capability. obtained statistical results - = 0.8694, MSE 0.7035), ANN 0.999, 0.0001026), ANFIS 0.99, 0.000041), showed that had best prediction lowest MSE. integrated GA (GA-ANFIS) gave optimization yield (96.72%) concentration wt%, methanol/mol ratio 10:1, time 2.5 h, temperature 70 °C, agitation speed 400 rpm. optimal developed properties successfully within ASTM D 6751 standards.

The objective of this research is to examine the problems shading effect photovoltaic (PV) systems. This describes PV system installed on rooftop administration building at Polytechnic State Ujung Pandang-Makassar, Indonesia (called PNUP). To achieve proposed method, PVsyst application was applied evaluate effect, loss diagram and performance ratio (PR) over entire year using software. scheme also examines financial analysis system, namely: payback period (PBP) return investment (ROI). Four perspective designs photo voltaic-filled with different tilts azimuth were selected. Research results indicated that PR designs_1, 2, 3 4 were: 0.816, 0.817 0.815. energy losses for all 11.40 MWh (design_1); 11.38 (design_2); 11.67 (design_3) 11.04 (design_4). In addition, investigated define PBP ROI. ROI 8.2 years 145.2 % rate; 144.3% 7.8 155.2 rate 8.6 131.8% rate.

The purpose of this research is to identify the optimal configuration a diesel generator with hybrid renewable energy system that can sustainably meet demands rural area. Some main challenges using generators supply required electric load in remote areas are high operating cost, unmet load, carbon dioxide emissions, very total net and quality electricity. This study, which combined resources, accurately analyzed eight different outputs from optimization multiple resources software. analysis considered factors such as site-specific conditions, fuel costs, solar radiation levels. software prefers following strategy over cycle charging strategy. involves combining sources, specifically configured combination photovoltaic cells, generator, wind turbine, battery. configuration, cost approximately $180,065.43 levelized $0.32, identified most effective chosen. Operating emission, present reduced by 53.17 %, 60.46 30.02 respectively. It highlighted energies their role promoting environmental sustainability. By providing 100 % demand, it increased electricity zero.

Growing population, burgeoning economic growth and technological advancements have caused a surge in electricity demand worldwide. In recent years, Pakistan, contributing less than 1% to global greenhouse gas emissions, has endured severe weather, including the 2022 floods that affected nearly 30 million people. Pakistan is developing country signatory of Paris accord made an international commitment cut down its GHG emissions. To date, total generation about 122,934 GWh, from which 60.9% (744,862 GWh) met by thermal sources (coal, oil gas), 23.7% (29,181 hydel, 12.4% (15,182 nuclear 3% (3709 done through renewable energy sources. The for rising exponentially, around fulfilled hydrocarbons. This study introduces novel approach assessing sector's emissions using CO2, CH4, N2O, expanding beyond traditional focus on CO2 alone. work uses time-varying carbon intensity calculate and, subsequently, fossil fuel-driven electrical systems. One notable aspect this capability with more frequent temporal resolution, frequently. peak are observed January December at values 650gCO2-eq/kWh 550gCO2-eq/kWh respectively, causing smog issues country. Results show during January, February, October, November relatively higher due unavailability hydel resources.
