What You'll Learn
Coal power plants cause thousands of deaths in the US
Research has revealed that coal power plant pollution has led to a substantial number of deaths in the US. A study examining data from 480 American coal plants between 1999 and 2020 found that approximately 460,000 deaths could be attributed to coal-fired power plant pollution during that period. This figure represents a "staggering" number of lives lost, with certain power plants contributing to at least 5,000 deaths each. The installation of pollution control technology, such as scrubbers, has been shown to significantly reduce mortality rates in surrounding areas, emphasizing the connection between coal plant emissions and adverse health outcomes.
The health effects of coal power plant pollution are wide-ranging and significant. Fine particle pollution from these plants can lead to respiratory issues, with higher rates of bronchitis observed in areas with poorer air quality. Additionally, stomach cancer incidence is elevated in regions with higher air pollution levels. Air pollution also impacts cardiovascular health, with a potential reduction of 10 to 15% in deaths and illnesses from cardiovascular disease achievable through substantial air pollution abatement. Furthermore, coal combustion can release toxic constituents, including transition metals, which can cause oxidative stress and inflammation in the body, exacerbating conditions such as diabetes and cardiovascular diseases.
The human cost of coal power plant pollution is not limited to the direct health impacts of air pollution. Coal mining, a critical aspect of the coal industry, has historically been the most dangerous energy activity, claiming the lives of numerous miners. In the US alone, over 100,000 coal miners have perished in accidents over the past century, underscoring the inherent risks associated with coal extraction.
The transition to cleaner energy sources, such as natural gas, is crucial to reducing the health and environmental impacts of coal power plants. While natural gas is not without its own challenges, such as methane leakage, it has the potential to substantially improve air quality and save tens of thousands of lives annually. Additionally, state policies that encourage a shift away from coal can play a significant role in reducing coal plant emissions and their associated health risks.

Coal combustion releases harmful PM2.5 particles
PM2.5 particles from coal combustion are particularly harmful due to their small size, which allows them to be easily inhaled and penetrate deep into the respiratory system. These particles can cause a range of health issues, including respiratory problems, cardiovascular disease, and even cancer.
The release of PM2.5 particles from coal combustion has been linked to increased mortality rates. Studies have found that exposure to these particles is associated with a higher risk of death, and the mortality rate increases with the level of exposure. For every 1 μg/m3 increase in coal PM2.5, mortality rates rise by approximately 1.12%. This is a significant increase and highlights the deadly nature of coal-related air pollution.
The harmful effects of coal combustion have been underestimated in the past, with PM2.5 from coal often being treated as equivalent to other sources of air pollution. However, research has revealed that coal-fired power plants are a major source of fine particulate matter pollution, and their emissions may be more deadly than previously thought. This is because coal PM2.5 is rich in toxic substances such as sulfur dioxide, black carbon, and metals, which can have severe health consequences.
The impact of coal combustion on human health has been the subject of several studies, with researchers examining Medicare records and emissions data to understand the link between coal-fired power plants and mortality rates. These studies have found a strong correlation between exposure to coal PM2.5 and increased deaths, with an estimated 460,000 deaths attributed to coal-fired power plant pollution between 1999 and 2020 in the United States alone. This highlights the urgent need to reduce coal emissions and improve air quality to protect public health.

Coal pollution is linked to diabetes and cardiovascular issues
Coal pollution is a significant contributor to air pollution, which has been linked to a range of adverse health effects, including respiratory and cardiovascular issues, as well as metabolic disorders such as diabetes.
Several studies have found a positive association between air pollution and type 2 diabetes mellitus (T2DM). For example, Lucht and colleagues' analysis showed that medium-term exposure to PM2.5 and accumulation mode particle number was associated with higher fasting blood glucose (FBG) levels in non-diabetic adults. Other studies have found similar associations between PM, nitrogen dioxide (NO2), and diabetic-related biomarkers. Additionally, air pollutants have been linked to impaired glucose metabolism, insulin resistance (IR), and T2DM.
The impact of air pollution on cardiovascular health is particularly prominent in patients with T2DM. Studies have shown that air pollution can negatively impact the cardiovascular health of individuals with T2DM, with male and older patients experiencing greater health losses. Furthermore, air pollution has been found to increase the risk of cardiovascular events and contribute to the development of cardiovascular disease (CVD). Fine particulate matter, such as PM2.5, can trigger cardiovascular disease-related heart attacks and death, especially in those with pre-existing heart conditions.
Diabetes is considered a major contributor to the global burden of disease and premature death. Cardiovascular disease is a significant complication in patients with T2DM, and it is estimated that nearly half of all deaths in patients with diabetes can be attributed to CVD. Air pollution, particularly fine particulate pollution, has been implicated in the development of CVD, including coronary heart disease, heart failure, stroke, and hypertension.
The link between air pollution and diabetes-related cardiovascular issues may be explained by the role of inflammation and oxidative stress. Studies suggest that air pollution can increase oxidative stress, which can exacerbate vascular complications in individuals with diabetes. Additionally, air pollution-induced inflammation may synergistically contribute to cardiac and vascular dysfunction, providing a potential causal link between air pollution, diabetes, and CVD.

Scrubbers reduce coal power plant deaths
Coal-fired power plants have been linked to a significant number of deaths, with air pollution from these sources causing tens of thousands of premature deaths in the United States alone each year. The adverse health effects of fine particulate matter (PM2.5) pollution from coal plants have been increasingly recognised, with research suggesting that it is more harmful and carries a greater mortality risk than previously thought.
The installation of scrubbers, or pollution control technology, on coal-fired power plants has been identified as a key intervention to reduce harmful emissions and improve public health. Scrubbers act as giant filters, removing over 90% of flue gases emitted by coal exhausts, specifically targeting SO2 emissions. The effectiveness of scrubbers in reducing emissions and associated health risks has been demonstrated in several studies. For example, the Keystone power plant in Pennsylvania saw a significant decrease in deaths attributable to coal pollution in the area after the installation of scrubbers, dropping from over 600 to below 100 deaths per year.
The impact of scrubbers on air quality and health has been further validated through research examining the link between power plant pollution and ambient PM2.5 levels. This research has shown that scrubbers can substantially reduce PM2.5 levels, which is significant given the established link between PM2.5 and increased risk of early death, as well as various diseases including lung and heart disease, cancer, and dementia.
The installation of scrubbers has been a key driver in the decline of certain types of air pollution and associated hospitalisations, particularly for Ischemic Heart Disease (IHD) in individuals aged 65 and above. This is supported by findings that areas with higher air pollution levels also experience greater rates of bronchitis, stomach cancer, and cardiovascular disease. The effectiveness of scrubbers in reducing SO2 emissions has been particularly noted, with a 90% reduction in sulfur dioxide emissions in facilities reporting the installation of scrubbers.
Overall, the implementation of scrubbers on coal power plant exhausts has been shown to significantly reduce harmful emissions, lower instances of heart disease, and contribute to a decline in mortality rates associated with coal-fired power plant pollution. These findings highlight the importance of continued efforts to reduce coal emissions and improve air quality, with scrubbers playing a crucial role in mitigating the health impacts of coal-fired power plants.

Coal pollution is declining due to EPA regulations and cheaper alternatives
Coal-fired power plants are a major source of fine particulate matter (PM2.5) air pollution, which is associated with an increased risk of death. Research has shown that coal pollution has led to a staggering number of deaths, with estimates ranging from 7,500 to 52,000 people in the United States dying prematurely due to small particles resulting from power plant emissions. One study even estimated that between 1999 and 2020, 460,000 deaths could have been avoided in the absence of emissions from coal power plants.
However, there is a declining trend in coal pollution-related deaths due to two main factors: EPA regulations and cheaper alternatives.
Firstly, EPA regulations have played a crucial role in reducing coal pollution. The Environmental Protection Agency (EPA) has implemented rules and standards aimed at reducing emissions and improving air quality. For example, the Mercury and Air Toxics Standards (MATS) targeted coal-fired power plants, and stricter regulations have required the use of pollution control devices such as scrubbers, which remove unwanted chemicals from smokestacks. These regulations have had a significant impact, with a sharp decline in air pollution deaths from coal-fired power plants after the mid-2000s, dropping from an average of 43,000 per year to just 1,600 in 2020.
Secondly, coal is becoming less popular due to cheaper and less polluting alternatives, such as natural gas, wind energy, and solar power. The average U.S. coal plant is now 39 years old, and many have been shut down or converted to natural gas. Between 2002 and 2018, 275 of the nation's 530 coal plants closed or were converted, and this trend is expected to continue.
The decline in coal pollution is a positive step for human health and the environment. It highlights the success of emissions reductions and the importance of continuing to reduce coal emissions and transition to cleaner energy sources. By understanding the health impacts of air pollution, targeted policies can be designed to further reduce the burden of coal pollution on public health.
While there has been progress, there are still concerns about the future of coal pollution regulations. The EPA has recently announced a rollback of some environmental regulations, which could have negative consequences for human health and the environment. Additionally, the coal industry continues to receive substantial federal tax subsidies, and there are concerns about the enforcement of regulations and the true costs of coal pollution. Nonetheless, the overall trend suggests a move away from coal towards cleaner and more cost-effective alternatives.

Frequently asked questions
Between 1999 and 2020, approximately 460,000 people in the United States died due to coal-fired power plant pollution.
Coal pollution contains PM2.5, which stands for particles smaller than 2.5 microns in width. These particles can contain transition metals and sulfur dioxide, which the body absorbs. This can cause oxidative stress, leading to inflammation that exacerbates conditions such as diabetes and cardiovascular issues.
Particulate pollution from coal plants is likely far more deadly than EPA regulations recognize. Exposure to fine particulate air pollutants from coal-fired power plants has an associated risk of mortality that is more than double that of PM2.5 from all other sources.
The number of deaths declined when coal plants installed pollution control technology (emissions scrubbers) or shut down. Moving towards cleaner energy sources, such as natural gas, can also help reduce coal pollution and the associated health risks and costs.
