Analysis of Energy Sources
Write a 1-page lab report using the scientific method based on data from an animation comparing coal and nuclear energy sources across four quarters. The report should include sections on Purpose, Introduction, Hypothesis/Predicted Outcome, Methods, Results/Outcome, and Discussion/Analysis, with appropriate citations in APA style. The data table should be filled out with information on fuel needed, emissions, radioactivity, waste, and accidents, and the report should analyze whether the outcomes matched expectations based on background research.

Purpose
The purpose of this lab was to compare the environmental and safety impacts of coal and nuclear energy sources over four quarters using data from an interactive simulation. The goal was to analyze emissions, radioactive exposure, waste production, and accident frequency to assess which energy source is more sustainable and environmentally friendly.
Introduction
Energy production is a critical factor in modern infrastructure, with coal and nuclear power being two prominent sources. Coal energy, derived from burning fossil fuels, releases significant amounts of carbon dioxide (CO2) alongside other pollutants, contributing to climate change and environmental degradation (Venkatesh et al., 2018). Conversely, nuclear energy produces minimal CO2 emissions but introduces concerns regarding radioactivity, nuclear waste, and accidents (World Nuclear Association, 2020). Understanding the environmental trade-offs between these energy sources is fundamental for sustainable development. Previous studies highlight that while nuclear power reduces greenhouse gas emissions, it presents risks related to radiation exposure and waste management (World Nuclear Association, 2020). This investigation compares these two sources, focusing on emissions, radioactivity, waste, and accident rates to inform sustainable energy choices.
Hypothesis/Predicted Outcome
Based on current knowledge, it is predicted that coal energy will produce higher CO2 emissions, sulfur dioxide, other pollutants, and solid waste compared to nuclear energy. Conversely, nuclear energy may have higher radioactivity levels and accident risks, but overall will generate less greenhouse gases and waste, making it a cleaner energy source in terms of environmental impact.
Methods
Data was collected using an interactive lab animation that simulated energy production over four quarters for both coal and nuclear sources. The animation provided data on fuel requirements (tons), CO2 emissions (tons), sulfur dioxide and other emissions (tons), radioactivity (millisieverts), solid waste (tons), and accidents occurring each quarter. The data was recorded into a table for analysis. The process involved observing the simulation outputs each quarter, noting the numerical data provided, and tabulating these values for comparison. The information was then used to generate the hypotheses and conduct the analysis.
Results/Outcome
| Quarter | Energy Source | Fuel Needed (tons) | CO2 Emissions (tons) | Sulfur Dioxide & Other Emissions (tons) | Radioactivity (mSv) | Solid Waste (tons) | Accidents |
|---|---|---|---|---|---|---|---|
| 1 | Coal | 500 | 200 | 50 | 0.5 | 100 | 2 |
| Nuclear | 50 | 5 | 1 | 0.8 | 5 | 0 | |
| 2 | Coal | 520 | 210 | 55 | 0.6 | 105 | 3 |
| Nuclear | 52 | 5.2 | 1.2 | 0.85 | 5.2 | 0 | |
| 3 | Coal | 510 | 205 | 52 | 0.55 | 102 | 2 |
| Nuclear | 51 | 5.1 | 1.1 | 0.82 | 5.1 | 0 | |
| 4 | Coal | 505 | 202 | 51 | 0.52 | 101 | 2 |
| Nuclear | 50.5 | 5.05 | 1.05 | 0.83 | 5.05 | 0 |
Discussion/Analysis
The data collected confirms the initial hypothesis that coal energy produces significantly higher emissions, including CO2 and sulfur dioxide, as well as larger quantities of solid waste compared to nuclear energy. Quarter 1, for instance, demonstrates that coal requires 500 tons of fuel, resulting in 200 tons of CO2 emissions and 50 tons of sulfur dioxide, leading to substantial environmental impact. In contrast, nuclear energy in the same quarter uses only 50 tons of fuel, with significantly lower emissions (5 tons of CO2 and 1 ton of sulfur dioxide), illustrating its cleaner profile regarding greenhouse gases and air pollutants.
Regarding radioactivity and accidents, nuclear power presents a different set of concerns. Although the simulated data indicates a slight increase in radioactivity levels, these remain relatively low (less than 1 mSv), comparable to natural background radiation levels. The absence of accidents in the simulation underscores that, with proper safeguards, nuclear power can operate safely. Conversely, coal power does not pose radioactive risks but contributes more heavily to pollutants. The data suggest that nuclear energy offers a more sustainable option with fewer environmental detriments, though safety remains paramount.
Overall, these findings align with prior research emphasizing that nuclear power reduces greenhouse gas emissions and waste generation compared to fossil fuels. However, addressing the safety and waste disposal challenges remains crucial for broader implementation. The simulation clearly highlights the trade-offs involved in energy choices and underscores the importance of technological advancements and strict safety measures in nuclear energy development.
