Abstract The global shift from a fossil fuel-based to an electrical-based society is commonly viewed as ecological improvement. However, the electrical power industry major source of carbon dioxide emissions, and incorporating renewable energy can still negatively impact environment. Despite rising research in energy, consumption on environment poorly known. Here, we review integration energies into electricity sector social, environmental, economic perspectives. We found that implementing solar photovoltaic, battery storage, wind, hydropower, bioenergy provide 504,000 jobs 2030 4.18 million 2050. For desalinization, photovoltaic/wind/battery storage systems supported by diesel generator reduce cost water production 69% adverse environmental effects 90%, compared full fuel systems. potential emission reduction increases with percentage sources utilized. photovoltaic/wind/hydroelectric system most effective addressing climate change, producing 2.11–5.46% increase generation 3.74–71.61% guarantee share ratios. Compared single systems, hybrid are more reliable better equipped withstand impacts change supply.

Floods are one of the most catastrophic natural disasters. Water level forecasting is an essential method avoiding floods and disaster preparedness. In recent years, models for predicting water levels have been developed using artificial intelligence techniques like neural network (ANN). It has demonstrated that more advanced sequenced-based deep learning techniques, long short-term memory (LSTM) networks, superior at hydrological data. However, historically, LSTM hyperparameters were based on experience, which typically did not produce best outcomes. The Particle Swarm Optimization (PSO) was utilized to adjust hyperparameter increase capacity learn data sequence characteristics. Utilizing observation from stations along Bangladesh's Brahmaputra, Ganges, Meghna rivers, model estimate flood dynamics. Nash Sutcliffe efficiency (NSE) coefficient, root mean square error (RMSE), MAE used assess model's performance, where PSO-LSTM outperforms ANN, PSO-ANN, in all stations. provides improved prediction accuracy stability improves varying lead times. findings may aid sustainable risk mitigation study region future.
