Fossil Fuels: Water Polluters Or Safe Energy?

Fossil fuels have been powering our world since the Industrial Revolution, with fossil fuels making up about 79% of total US primary energy production in 2022. However, burning fossil fuels releases large amounts of carbon dioxide, nitrogen oxides, and other harmful substances into the atmosphere, contributing to air pollution and water pollution, global warming, and climate change. The environmental impacts of fossil fuels extend beyond pollution, with mining and drilling for fossil fuels destroying animal habitats and contributing to ocean acidification, which threatens marine life and coastal communities. In addition, the extraction, transportation, and refining of fossil fuels can lead to oil spills, which have devastating effects on ecosystems, wildlife, and communities. As we continue to rely on fossil fuels, it is important to consider their impact on water pollution and explore alternatives to mitigate their harmful effects.

Oil spills

Additionally, oil spills can wreak havoc on the insulating and waterproofing abilities of feathers and fur, causing birds and marine mammals to succumb to hypothermia. Ingesting oil can be toxic for animals, and the damage to their habitats and reproductive rates may hinder the long-term recovery of affected populations. Oil spills also harm sensitive ecosystems like saltwater marshes, mangroves, and wetlands, which are vital for biodiversity.

The Deepwater Horizon oil spill in 2010, for instance, resulted in smoke from controlled oil burns and left a rainbow sheen on the water—a telltale sign of oil floating on the surface. The Exxon Valdez oil spill in 1989 also highlighted the challenges of cleanup efforts, as the use of high-pressure, hot-water hoses to clean beaches was found to cause more damage than the oil itself.

Fracking fluids

Fracking, or hydraulic fracturing, is a popular method for extracting oil and gas in the United States. The process involves injecting water and chemicals at high pressure into wells to crack shale rock deep underground and release oil and gas. While fracking has been a convenient method for extracting fossil fuels, it has also raised concerns about its impact on water resources.

The Wind River Basin in the American West also faces a similar issue, with studies indicating that the entire groundwater resource in the basin is contaminated with chemicals linked to hydraulic fracturing. This contamination can occur due to the upward flow of groundwater in the basin, which can bring deep underground contaminants closer to the surface over time.

While the oil and gas industry is subject to certain environmental regulations, exemptions like the "'Halliburton loophole'" have been criticized for excluding hydraulic fracturing from specific regulations, such as the Safe Drinking Water Act's Underground Injection Control Program. This loophole, passed as part of the Energy Policy Act of 2005, highlights the complex regulatory landscape surrounding fracking and its potential impact on water resources.

The activities that pose the most significant threats to water resources include spills and leaks of fracking fluids, the injection of fluids into poorly constructed wells, and inadequate wastewater management practices. These issues can result from human error, equipment failure, or the inability of wastewater treatment facilities to handle fracking waste properly. As a result, contaminants can enter surface water resources and pose risks to both the environment and human health.

Nitrogen oxides

Nitrogen is the most abundant element in the air and is essential to plant and animal life. However, human activities, such as the burning of fossil fuels, can upset the natural balance of nitrogen in the environment. When fossil fuels are burned, they release nitrogen oxides into the atmosphere, which contribute to the formation of smog and acid rain.

The presence of excess nitrogen in the atmosphere, in the form of nitrogen oxides or ammonia, is deposited back onto land, where it washes into nearby water bodies. These excess nutrients contribute to water pollution, harmful algal blooms, and oxygen-deprived aquatic zones. Excess ammonia and low pH in these areas are toxic to aquatic organisms and affect their survival.

To reduce nitrogen oxide emissions, businesses can take steps to understand and manage their greenhouse gas emissions. Increasing energy efficiency is one way to reduce emissions and improve a corporation's bottom line. Additionally, individuals can help by conserving energy and reducing their use of cars and trucks, which produce significant amounts of nitrogen oxide emissions.

Ocean acidification

The burning of fossil fuels is a major contributor to ocean acidification. Since the Industrial Revolution, the oceans have absorbed around one-third of all the carbon dioxide (CO2) released from fossil fuels. This has transformed the chemistry of the ocean, increasing its average acidity by 30%.

The process of ocean acidification occurs when carbon dioxide dissolves into the ocean, triggering a chemical reaction that increases acidity over time. The CO2 and water produce carbonic acid, which releases hydrogen and bicarbonate ions. The more hydrogen ions there are, the more acidic the water becomes.

In addition, ocean acidification can disrupt the ocean's ability to stabilize the Earth's climate, protect coastal communities, and provide food for billions of people worldwide. It is essential to address this issue through a transition to clean energy, the implementation of pollution regulations, and the enhancement of natural carbon sinks to mitigate the effects of ocean acidification and protect vulnerable industries and ecosystems.

Furthermore, the burning of fossil fuels releases nitrogen oxides and ammonia into the atmosphere, contributing to the formation of smog and acid rain. These pollutants can be deposited back onto land and wash into nearby water bodies, causing excess nutrients that contribute to harmful algal blooms and oxygen-deprived aquatic zones, further threatening aquatic life.

Air pollution

The combustion of fossil fuels (coal, diesel fuel, gasoline, oil, and natural gas) for electricity production, heating, transportation, and industry is the leading cause of air pollution worldwide. The burning of fossil fuels releases large amounts of carbon dioxide, a greenhouse gas, into the atmosphere. These gases trap heat, causing global warming and climate change, which include extreme weather events, rising sea levels, and ocean acidification.

The combustion of fossil fuels releases nitrogen oxides, contributing to smog and acid rain formation. These emissions also cause eutrophication, which harms aquatic ecosystems by lowering oxygen levels. Additionally, the burning of gasoline additives produces ultra-fine particles and aromatic hydrocarbons, which are carcinogenic.

To mitigate air pollution, businesses can play a crucial role by managing and reducing their greenhouse gas emissions. This can be achieved by preparing annual inventories, setting long-term emission reduction targets, improving energy efficiency, and purchasing renewable energy. Individuals can also contribute by conserving energy, such as through the use of energy-efficient appliances and reducing vehicle usage.
