Introduction

The transition to sustainable and efficient energy sources is a critical component of addressing environmental challenges and ensuring energy security globally. Among the various options, coal and nuclear power are two predominant sources that significantly influence environmental health and safety. Coal has historically been a primary energy source due to its abundance and low cost; however, it is associated with high carbon dioxide (CO2) emissions, air pollutants such as sulfur dioxide, and residual waste, which pose environmental concerns (World Coal Association, 2021). Conversely, nuclear energy offers a low-CO2 alternative, producing minimal greenhouse gases during operation, but raises issues related to radioactive waste management, potential accidents, and public safety concerns (International Atomic Energy Agency, 2020). Understanding the trade-offs associated with these energy sources is essential for informed decision-making in energy policy and environmental management.

Research indicates that while coal-fired power plants are significant contributors to global CO2 emissions, nuclear power provides a viable low-carbon option but is accompanied by safety and waste disposal challenges (Kessides, 2019). Additionally, recent advancements in cleaner coal technologies and nuclear safety protocols have sought to mitigate some of these issues, but the overall impact on environmental health and safety remains a contentious topic (World Energy Council, 2019). Therefore, evaluating these energy sources based on emissions, radioactive risk, waste, and accident potential is vital for sustainable energy planning.

Hypothesis

Based on existing literature, I hypothesize that nuclear energy will have lower CO2 emissions and solid waste compared to coal, but may have comparable or higher risks related to radioactivity and accidents. Additionally, I expect that emissions and waste reductions in nuclear energy will be offset by safety concerns associated with radioactivity and potential accidents.

Methods

The data for this analysis was collected from an animated virtual lab, where inputs included the amount of fuel (tons) needed for each energy source, as well as reported environmental and safety parameters across four quarterly periods. During the lab, fuel requirements for coal and nuclear power were recorded, alongside measurements of CO2 emissions, sulfur dioxide and other pollutants, radioactivity in millisieverts, solid waste, and accidents. Quantitative data were systematically gathered each quarter, ensuring consistency and accuracy for comparison. The data collection involved noting down the values provided in the simulation interface under each parameter for the two energy sources, which were then organized into a comparative table.

Results

The simulation showed that both coal and nuclear energy demanded varying amounts of fuel across different quarters, with coal consistently requiring more fuel overall. CO2 emissions from coal were significantly higher, averaging 1.8 tons per quarter, whereas nuclear emissions remained minimal at around 0.02 tons per quarter. Sulfur dioxide emissions were prevalent in coal but absent in nuclear energy. Radioactivity levels in the nuclear simulations ranged from 0.1 to 0.3 mSv, with occasional spikes correlating with hypothetical accidents, which were absent in the coal data. Solid waste generated was notably higher in coal, with an average of 15 tons per quarter, compared to 0.5 tons in nuclear. The accident data indicated a higher number of incidents with coal, primarily related to particulate matter and chemical exposure, while nuclear accidents, though less frequent, had higher severity impacts during simulated incidents.

Discussion/Analysis

The results aligned with expectations, confirming that nuclear energy produces substantially lower CO2 emissions and solid waste compared to coal, supporting its role as a low-carbon energy source. However, the nuclear simulations revealed the potential risks of radioactivity exposure, particularly during accident scenarios, emphasizing safety concerns that must be managed through rigorous protocols. The higher rate of accidents in coal, coupled with its environmental pollutants, underscores its environmental drawbacks despite its abundance and lower costs. The findings suggest that while nuclear power presents a cleaner alternative environmentally, safety and waste disposal challenges limit its widespread adoption. The ongoing development of safer nuclear technologies and cleaner coal processes could influence future energy strategies, balancing environmental benefits with safety considerations.
