Social, environmental, and economic consequences of integrating renewable energies in the electricity sector: a review

Environmental Chemistry Letters, Journal Year: 2023, Volume and Issue: 21(3), P. 1381 - 1418

Published: March 24, 2023

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.

Published: March 17, 2022

The concentration of greenhouse gases (GHGs) in the atmosphere has been increasing since beginning industrial revolution. Nitrous oxide (N2O) is one mightiest GHGs, and agriculture main sources N2O emissions. In this paper, we reviewed mechanisms triggering emissions role agricultural practices their mitigation. amount produced from soil through combined processes nitrification denitrification profoundly influenced by temperature, moisture, carbon, nitrogen oxygen contents. These factors can be manipulated to a significant extent field management practices, influencing emission. relationships between occurrence regulating it are an important premise for devising mitigation strategies. Here, evaluated various options literature found that effectively reduced intervening on time method N supply (30–40%, with peaks up 80%), tillage irrigation (both non-univocal way), use amendments, such as biochar lime (up slow-release fertilizers and/or inhibitors 50%), plant treatment arbuscular mycorrhizal fungi 75%), appropriate crop rotations schemes integrated nutrient (in way). conclusion, acting (fertilizer type, dose, time, method, etc.) most straightforward way achieve reductions without compromising yields. However, tuning rest (tillage, irrigation, rotation, principles good also advisable, fetch abatement vs. risk unexpected rise, which incurred unwary management.

Alternatives to Water Photooxidation for Photoelectrochemical Solar Energy Conversion and Green H₂ Production

Advanced Energy Materials, Journal Year: 2022, Volume and Issue: 12(42)

Published: Sept. 22, 2022

Abstract Photoelectrochemical (PEC) water splitting is considered a promising technology to produce renewable hydrogen, clean fuel or energy carrier replace conventional carbon‐based fossil‐fuel sources. Nevertheless, the overall solar‐to‐hydrogen efficiency and cost‐effectiveness of this are still unsatisfactory for practical implementation. This can be primarily attributed sluggish kinetics anodic oxygen evolution reaction (OER) relatively low economic value cogenerated O 2 production. Over past decades, there extensive efforts explore more kinetically favorable photooxidation reactions, which coupled with hydrogen (HER) simultaneously improve H production yield higher valuable alternatives . review aims present recent progress on alternative choices OER. Here, fundamental PEC critical components required system first shortly summarized. Then benefits issues reactions including peroxide, chlorine, alcohol, 5‐hydroxymethylfurfural, urea oxidation when combined concurrent HER, reviewed analyzed. concluded by presenting evaluation challenges opportunities these HER‐coupled solar environmental treatment.

Environmental contamination research has been quite interesting in bioindicators recently. The basic objective of bioindicator is to find species that can reliably detect environmental disturbances and demonstrate how those affect other or biodiversity as a whole. Since they frequently come into contact with the harmful substances found soil, water, air, insects are particularly valuable for evaluating human activities terrestrial ecosystem, aquatic system, atmosphere. In this review article, we’ve emphasized use resource assessing contaminants monitoring contamination. Insects have our main focus since key indicators changes air quality. majority insects, including beetles, ants, honey bees, butterflies employed study biological sensitive even slightest also used monitor different toxins.
