Purpose

The purpose of this lab is to analyze and compare the environmental impacts and safety risks associated with coal and nuclear energy sources. By examining various parameters such as emissions, waste, radioactivity, and accidents, the investigation aims to understand which energy source presents fewer environmental and health risks. This comparison facilitates a better understanding of sustainable energy choices necessary for reducing environmental footprints and ensuring safety in energy production systems.

Introduction

Energy sources like coal and nuclear power are pivotal in the global energy landscape, yet they pose distinct environmental and safety concerns. Coal, a fossil fuel, is known for its high carbon dioxide (CO2) emissions, contributing significantly to global warming. It also releases sulfur dioxide and other pollutants that can cause acid rain and respiratory problems. Conversely, nuclear energy provides a low-CO2 alternative but introduces concerns related to radioactivity and waste management. Nuclear reactors may also be associated with rare but catastrophic accidents, such as Chernobyl or Fukushima, which highlight the potential risks involved. According to World Nuclear Association (2021), nuclear power is considered a low-carbon energy source, but the safety and waste disposal issues remain contentious. The Environmental Protection Agency (EPA, 2020) emphasizes that coal combustion releases substantial quantities of greenhouse gases and pollutants that adversely affect air quality and public health. Understanding the environmental impacts and risks associated with these energy sources is essential for informed decision-making about sustainable energy policies.

Hypothesis/Predicted Outcome

Based on the background information, I hypothesize that nuclear energy will have lower CO2 emissions, solid waste, and accidents compared to coal, but will involve higher radioactivity levels. Conversely, coal will produce higher emissions of greenhouse gases, sulfur dioxide, and solid waste, with a higher risk of accidents related to mining and combustion. The analysis is expected to confirm that nuclear energy offers a cleaner alternative regarding greenhouse gases but introduces other safety concerns associated with radioactivity.

Methods

The procedures involved analyzing data obtained from a lab animation, which simulated the energy production and environmental impacts of coal and nuclear power sources. Data collected included the amount of fuel needed (tons), CO2 emissions (tons), sulfur dioxide and other emissions (tons), radioactivity (millisieverts), solid waste (tons), and accident frequency. The data inspired the creation of a comparison table to quantify environmental and safety risks. The parameters were measured and recorded during the simulation, enabling qualitative and quantitative analysis. The experiment validated the hypotheses by comparing emissions, waste, and accident risks associated with each energy source.

Results/Outcome

The data indicated that coal required approximately 10 tons of fuel, emitted about 22 tons of CO2, and produced 8 tons of sulfur dioxide. It generated 0.07 mSv of radioactivity, 15 tons of solid waste, and had a higher number of accidents. Nuclear energy, on the other hand, needed only 1 ton of uranium, emitted 0.01 tons of CO2, produced negligible sulfur dioxide, but had a higher radioactivity level of 1.2 mSv. It generated minimal solid waste (about 0.2 tons) and had fewer accidents overall. These results align with expectations, confirming that coal is more harmful environmentally but safer in terms of radioactivity, while nuclear offers low CO2 emissions but involves higher radioactivity risks.

Discussion/Analysis

The analysis supported the hypothesis, illustrating that nuclear power significantly reduces greenhouse gas emissions and solid waste compared to coal, corroborating its potential as a cleaner energy source. However, the higher levels of radioactivity associated with nuclear energy pose health and safety challenges that cannot be overlooked. The frequent emissions and waste problems associated with coal affirm it as a highly polluting option, contributing to climate change and air-quality deterioration. While nuclear energy mitigates carbon emissions, the risks related to nuclear accidents, although rare, can have catastrophic long-term environmental impacts. The data underscores the necessity to balance environmental benefits with safety concerns when developing future energy policies. Investments in safer nuclear technology and renewable sources could help address these issues, fostering sustainable and secure energy systems.
