Introduction

Coal mining has historically been a significant source of economic growth worldwide; however, it also poses profound environmental challenges, particularly concerning water pollution. Acid mine drainage (AMD), a common byproduct of coal mining, results when sulfuric acid forms as sulfide minerals like pyrite undergo oxidation. This process leads to acidification of water bodies, adversely affecting aquatic ecosystems and water quality (Singh et al., 2020). The primary objective of this research is to examine the impact of coal mining on water pH levels, predicting that areas affected by mining are likely to exhibit decreased pH due to acid runoff. Furthermore, the study investigates how different environmental factors influence solar energy generation, assessing the potential for renewable energy solutions to mitigate environmental impacts.

Effects of Coal Mining on Water pH

To evaluate the influence of coal mining on water quality, water samples from areas affected by mining activities and control samples from unaffected sites were tested for pH levels before and after exposure to simulated conditions. The initial pH of the water samples was recorded, with mine-affected samples expected to show a lower pH, indicating increased acidity (Khan et al., 2017). The formation of substances such as iron hydroxides and sulfuric acid within the samples confirmed the chemical reactions associated with AMD. The final pH measurements typically reveal a significant decrease in water acidity in samples exposed to pyrite oxidation, confirming that coal mining releases acidic compounds into water bodies.

Environmental Impact Prediction

The environmental implications of coal mining are profound, primarily due to the contamination of water sources with acid mine drainage. The lowered pH disrupts aquatic life, reduces biodiversity, and compromises water safety for human consumption (Huang et al., 2019). The hypothesized outcome aligns with existing literature indicating that mining activities exacerbate water acidity and leach harmful metals into ecosystems. Therefore, mitigation strategies such as neutralization with alkaline agents and preventative land management are critical to minimize environmental damage.

Solar Energy Experimentation and Analysis

Complementing the water quality assessments, the second part of the experiment investigates how sunlight exposure and different environmental factors affect solar energy collection using solar cells. The experimental data shows that the motor attached to the solar panel rotates more rapidly under direct sunlight compared to shaded or filtered conditions. The hypothesis posited that increased sunlight improves energy output, which was confirmed by observations demonstrating higher revolutions per minute (RPM) under full sun exposure versus shaded conditions (Mishra & Tiwari, 2018). The use of colored filters indicated that specific wavelengths of light are more effective in generating electricity, with blue and green filters allowing greater RPMs owing to the transmission of wavelengths that solar cells most efficiently convert to electrical energy.

Impact of Environmental Variables on Solar Power

Environmental factors such as shading, light spectrum, and the angle of sunlight significantly influence solar panel efficiency. When the solar panel was shaded using different configurations, a marked decrease in RPM was observed, underscoring the importance of unobstructed sunlight for maximum energy conversion. Similarly, varying the angle of sunlight affected the motor's speed; optimal angles resulted in higher RPMs, highlighting the importance of sun-tracking mechanisms in real-world applications (Chauhan et al., 2019). The use of colored filters demonstrated that certain wavelengths are more compatible with photovoltaic cells, indicating the potential benefits of spectral optimization or selective filtering to enhance solar energy harvesting in different environmental conditions (Kalogirou, 2020).

Summary and Environmental Implications

The findings from both experiments underscore the environmental impact of coal mining and the potential of solar energy as a sustainable alternative. The acidification of water sources near mining areas confirms the necessity for stricter environmental regulations and remediation techniques to prevent ecological degradation. Concurrently, the study on solar energy illustrates how environmental factors influence renewable energy efficiency, emphasizing the importance of optimizing solar panel deployment in variable sunlight conditions. The integration of environmental protection with renewable energy advancements presents a promising pathway toward sustainable development and the mitigation of climate change impacts.

Conclusion

This research confirms that coal mining significantly affects water quality, primarily through acid mine drainage leading to lowered pH levels. The ecological consequences are severe, impacting aquatic life and community water sources. Meanwhile, the solar energy experiments affirm that environmental variables, such as shading and spectral filters, critically influence energy generation efficiency. Future strategies should incorporate both pollution control in mining operations and technological innovations in solar energy to promote environmental sustainability. Implementing best practices in land management, pollution mitigation, and renewable energy deployment can collectively reduce adverse environmental effects and support a resilient ecological and energy future.
