What You'll Learn
The environmental impact of fossil fuel extraction
Fossil fuels are fossilized, buried remains of plants and animals that lived millions of years ago. Coal, crude oil, and natural gas are all examples of fossil fuels. The extraction of fossil fuels has significant environmental and health costs, known as externalities. These externalities are not reflected in market prices.
Air Pollution
Fossil fuels produce hazardous air pollutants, including sulfur dioxide, nitrogen oxides, particulate matter, carbon monoxide, and mercury. These pollutants are harmful to both the environment and human health. Air pollution from fossil fuels can cause acid rain, eutrophication, damage to crops and forests, and harm to wildlife. It can also cause respiratory problems and other health issues such as asthma, cancer, heart disease, and premature death. In 2018, 350,000 premature deaths in the United States were attributed to fossil fuel-related air pollution.
Water Pollution
Oil spills and leaks during extraction or transportation of fossil fuels can pollute drinking water sources and jeopardize freshwater and ocean ecosystems. For example, the 2010 BP Deepwater Horizon oil spill released 134 million gallons of oil into the Gulf of Mexico, killing 11 people and countless animals, and costing BP $65 billion in penalties and cleanup costs. Additionally, fracking fluids and wastewater from drilling operations can contaminate groundwater and drinking water with toxic substances like arsenic, lead, chlorine, and mercury.
Global Warming and Climate Change
The burning of fossil fuels emits greenhouse gases, such as carbon dioxide, which trap heat in the Earth's atmosphere and contribute to climate change. Since the Industrial Revolution, fossil fuels have warmed the planet by about 1.7 degrees Celsius, and the world has experienced its warmest winter on record, with Arctic sea ice at a new low. Fossil fuel-powered vehicles, such as passenger cars and trucks, are a significant source of heat-trapping emissions, contributing to extreme weather events like wildfires, droughts, and flooding.
Soil Pollution
Coal mining operations can wash toxic runoff into streams, rivers, and lakes, and dump unwanted rock and soil into waterways, further contributing to water pollution.
The environmental and health impacts of fossil fuel extraction disproportionately affect communities of color and low-income communities. Moving towards a clean energy future and phasing out fossil fuels are crucial steps to mitigate these impacts and reduce emissions.

The health impact of fossil fuel extraction
Fossil fuels are known to be a major driver of climate change, and the impacts of this are already being felt around the world. Wildfires, droughts, extreme temperatures, and flooding are becoming more frequent and intense, and the health impacts of these events are significant. People are losing their homes, struggling to access clean water and food, and are dealing with the health consequences of extreme heat. Climate change affects everyone, but it disproportionately impacts those who face discrimination and marginalization.
The extraction, transportation, and refining of fossil fuels also have direct health impacts. Oil spills, for example, can cause significant harm to both human communities and wildlife. The 2010 BP Deepwater Horizon spill in the Gulf of Mexico released 134 million gallons of oil, killing 11 people and countless animals, and costing BP $65 billion in penalties and cleanup costs. In addition to these immediate impacts, oil spills can also destroy habitats, erode shorelines, and result in the closure of beaches, parks, and fisheries, impacting the livelihoods of those who depend on these resources.
Air pollution from burning fossil fuels is another major health concern. It can cause and exacerbate respiratory ailments such as asthma and bronchitis, and increase the risk of cardiovascular and pulmonary diseases, as well as cancer. Globally, fossil fuel pollution is responsible for one in five deaths. In the United States alone, 350,000 premature deaths in 2018 were attributed to fossil fuel-related pollution. The combustion of additives found in gasoline, such as benzene and toluene, produces cancer-causing ultra-fine particles and aromatic hydrocarbons.
The health impacts of fossil fuel pollution disproportionately affect certain communities. In the United States, Black and Hispanic Americans are exposed to significantly higher levels of particulate matter pollution than other demographic groups. In Louisiana, an area known as "Cancer Alley," which is predominantly Black and low-income, the cancer risk is nearly 50 times the national average due to the proximity of numerous chemical plants and oil refineries. Similarly, Asian American, African American, and Latino residents in the Northeast and Mid-Atlantic regions experience higher levels of air pollution from vehicles.
The transition to renewable energy sources, such as wind, solar, geothermal, hydroelectric, and biomass, offers substantial health benefits by reducing air pollution and mitigating climate change. However, it is important to ensure a just transition that takes into account the livelihoods and economies of communities currently dependent on the fossil fuel industry.

The contribution of fossil fuels to global warming
Fossil fuels have been a dominant source of energy since the invention of the first coal-fired steam engines in the 1700s. The burning of fossil fuels, including coal, oil, and natural gas, releases carbon dioxide (CO2) and other greenhouse gases into the atmosphere, contributing to global warming and climate change.
According to the Intergovernmental Panel on Climate Change (IPCC), fossil fuels are the primary cause of global warming. In 2018, 89% of global CO2 emissions were attributed to fossil fuels and industrial activities. Coal, a fossil fuel, is considered the "dirtiest" of them all, responsible for over 0.3°C of the 1°C increase in global temperatures. Oil combustion releases significant carbon emissions, accounting for approximately one-third of the world's total carbon emissions. Natural gas, while promoted as a cleaner alternative, is still a fossil fuel that contributes to a fifth of the world's carbon emissions.
The combustion of fossil fuels has led to a rapid increase in atmospheric CO2 concentrations. The greenhouse effect, caused by the accumulation of greenhouse gases, results in warming temperatures. Since the Industrial Revolution, fossil fuels have raised global temperatures by about 1.7°C. If all accessible fossil fuel reserves were utilized, the planet's temperature would increase by an additional 2.8°C, surpassing the recommended threshold for avoiding catastrophic climate change.
The extraction and combustion of fossil fuels have far-reaching consequences for ecosystems and human health. Power plants that burn fossil fuels disrupt local ecosystems by withdrawing large volumes of freshwater for cooling systems. The subsequent release of warm water can stress aquatic species. Additionally, the burning of fossil fuels releases airborne particles, such as soot, which contribute to the melting of ice and snow, altering local patterns of freshwater availability.
To address the issue of global warming, there have been campaigns and agreements aimed at reducing fossil fuel usage and transitioning to renewable energy sources. The Paris Agreement, signed by world governments in 2015, committed to reducing carbon emissions. However, fossil fuel companies continue to be major polluters, investing heavily in advertising campaigns that promote their commitment to clean energy while maintaining a predominant focus on oil and gas expenditures.

The economic implications of fossil fuel use
Fossil fuels have played a dominant role in global energy systems since the Industrial Revolution. However, their use has significant economic implications, which are becoming increasingly apparent.
Firstly, the economic costs of fossil fuel use are substantial. In the United States, for example, consumers and businesses spent an estimated $921 billion on fossil fuels in 2006, amounting to nearly 7% of the country's gross domestic product. This expenditure surpasses that of critical sectors such as education and defense. The costs of fossil fuels extend beyond direct purchases, as the pollution they generate inflicts additional expenses on healthcare, the environment, and overall quality of life. The burning of fossil fuels contributes to global warming, leading to more frequent and severe extreme weather events, including wildfires, hurricanes, wind storms, flooding, and droughts. These events incur significant financial costs, with the price of extreme weather conditions in the United States between 2016 and 2020 estimated at $606.9 billion.
Secondly, fossil fuel combustion is the leading contributor to global warming, which poses a looming environmental and human catastrophe. The economic implications of this are twofold. Firstly, the direct costs of global warming are significant. For example, a 2008 study estimated that high-intensity hurricanes could cause up to $422 billion in damages in Atlantic and Gulf Coast states between 2025 and 2100. Secondly, there are indirect costs associated with the impact of global warming on agriculture and food security. A 2007 study found that global warming led to significant losses in three of the six largest global crops between 1981 and 2002.
Thirdly, the production, transportation, and refining of fossil fuels carry inherent risks of accidents and environmental disasters. For instance, the 2010 BP Deepwater Horizon oil spill in the Gulf of Mexico resulted in $65 billion in penalties and cleanup costs. Similarly, the collapse of a coal ash pond outside a Tennessee Valley Authority power plant in 2008 caused 300 acres of sludge, with an estimated cleanup cost of $825 million.
Lastly, the externalities of fossil fuel use, such as air and water pollution, impose significant economic burdens. Air pollution from fossil fuels has been estimated to cost $9 trillion between 1970 and 2000, including costs from pollution-induced early mortality, illness, healthcare expenses, and lost productivity. Water pollution from oil spills and fracking fluids contaminates groundwater and drinking water sources, further exacerbating the economic and health impacts.
In summary, the economic implications of fossil fuel use are far-reaching and significant. The direct and indirect costs associated with fossil fuels, including their environmental and health impacts, highlight the urgency of transitioning to a clean energy future.

The alternatives to fossil fuels
Fossil fuels, such as coal, oil, and gas, are the dominant sources of fuel emissions. However, there are several alternatives to fossil fuels that are growing in use. These alternatives are often collectively referred to as "clean energy", although some forms are cleaner than others. The five primary alternatives to fossil fuels are renewable energy, nuclear power, hydrogen, biomass, and geothermal energy.
Renewable energy is derived from natural sources that can replenish themselves, such as wind, solar, tidal, or hydroelectric power. Renewable energy sources are theoretically infinite, unlike fossil fuels, which will eventually run out. Additionally, renewable energy is the most affordable source of power in most parts of the world, with over 90% of new renewable projects being cheaper than fossil fuel alternatives. However, one drawback of renewable energy is that it is dependent on variable natural factors such as sunlight, wind, and water levels, which can cause the energy created to fluctuate or fall to zero.
Nuclear power is derived from controlled fission reactions in materials like plutonium or uranium. While nuclear energy is considered clean and efficient, it is not renewable, and there is a risk of accidents and the challenge of safely disposing of radioactive waste.
Hydrogen is another alternative fuel, particularly for heavy transport such as ships, trucks, and aircraft. However, its production currently relies on existing energy supplies.
Biomass, which includes biological material such as wood, plants, and crop residues, can be used to reduce emissions from coal-fired plants. However, burning biomass still produces greenhouse gases.
Geothermal power harnesses the Earth's natural sources of heat, particularly volcanic activity, to generate electricity. This form of energy is restricted to areas with volcanic sources, such as Iceland, where it provides 30% of all electricity power.
The transition to these alternatives is driven by the need to reduce our reliance on fossil fuels due to their environmental and geopolitical risks, as well as the economic benefits and job creation potential of clean energy sources.
