The Evolution Of Fuel Burning: Past, Present, Future

The burning of fossil fuels has changed significantly over time. The use of fossil fuels as a source of energy began around the Industrial Revolution, and since then, the amount and type of fossil fuels burned have changed. In the past 50 years, more than half of all the fossil fuels ever consumed have been burned, and the consumption of fossil fuels has increased eightfold since 1950. The burning of fossil fuels is the primary cause of current climate change, and it is having far-reaching effects on our climate and ecosystems.

Fossil fuels' environmental impact

Fossil fuels have been a key driver of technological, social, economic, and developmental progress since the Industrial Revolution. However, their impact on the environment and human health has been detrimental. The burning of fossil fuels has severe environmental and health consequences, which are not reflected in market prices. These costs, known as externalities, are incurred at every stage of the fossil fuel supply chain, from extraction and transportation to refining and burning.

Climate Change and Global Warming

The burning of fossil fuels releases large amounts of carbon dioxide and other greenhouse gases into the atmosphere. Carbon emissions trap heat, leading to global warming and climate change. The average global temperature has already increased by 1°C, and warming above 1.5°C risks further sea level rise, extreme weather events, biodiversity loss, species extinction, food scarcity, and worsening health and poverty for millions worldwide. Fossil fuels are the dominant cause of global warming, with 89% of global CO2 emissions in 2018 attributed to their use.

Ocean Acidification

The ocean absorbs about a quarter of all carbon emissions from fossil fuels, which changes its chemistry by increasing acidity. This makes it difficult for marine organisms to build shells and coral skeletons, posing threats to coral reefs, fishing, tourism, and the economy. Ocean acidification has increased by 30% over the last 150 years.

Extreme Weather

Climate change, caused by the burning of fossil fuels, contributes to more frequent and severe extreme weather events, including wildfires, hurricanes, wind storms, flooding, and droughts. These events have resulted in significant economic costs, with a price tag of $606.9 billion between 2016 and 2020 in the United States alone.

Sea Level Rise

Oceanic and atmospheric warming due to climate change are melting glaciers and land-based ice sheets, leading to global sea level rise. Sea levels have risen by about 9 inches since the late 1800s, causing more frequent flooding, destructive storm surges, and saltwater intrusion.

Air Pollution

Fossil fuels emit hazardous air pollutants, including sulfur dioxide, nitrogen oxides, particulate matter, carbon monoxide, and mercury. These pollutants contribute to local air pollution, which is linked to millions of premature deaths each year. Air pollution from fossil fuels can cause respiratory diseases, asthma, cancer, heart disease, and premature death. Globally, fossil fuel pollution is responsible for one in five deaths.

Water Pollution

Fossil fuel extraction, transportation, and refining can lead to oil spills and water pollution. Fracking, a controversial method of extraction, uses toxic fluids that contaminate drinking water sources and jeopardize freshwater and ocean ecosystems. Each fracking well uses between 1.5 million and 16 million gallons of water, and the resulting wastewater often contains harmful substances like arsenic, lead, chlorine, and mercury.

Plastic Pollution

Over 99% of plastics are made from fossil fuels, and 300 million tons of plastic waste are produced globally each year. 14 million tons of this waste ends up in the ocean, killing wildlife and polluting the food chain. The plastic industry's greenhouse gas emissions are expected to surpass those of coal-fired power plants by 2030.

Environmental and Ecosystem Destruction

The unearthing, processing, and transportation of fossil fuels take a significant toll on landscapes and ecosystems. Critical wildlife habitats are destroyed, and even when animals can escape, they are forced into less suitable habitats and must compete for resources. Oil spills and leaks during extraction or transport can destroy habitats, erode shorelines, and result in beach, park, and fishery closures.

Health Impacts

The burning of fossil fuels disproportionately affects communities of color and low-income communities. In the United States, the highest number of deaths per capita due to fossil fuel-related pollution occurred in states like Pennsylvania, Ohio, and West Virginia. The environmental and health impacts of fossil fuels have led to asthma, cancer, heart disease, and premature deaths.

To address these issues, the world needs to transition rapidly towards low-carbon sources of energy, such as nuclear and renewable alternatives.

The rise of renewable energy sources

The burning of fossil fuels has been a dominant global energy system for centuries, but the rise of renewable energy sources is shifting this dynamic. Renewable energy technologies first emerged in response to the oil embargoes of the 1970s, but their popularity was short-lived. However, in recent years, there has been a resurgence in the development and adoption of renewable energy sources, such as solar cells, wind turbines, and biofuels.

Solar energy, also known as photovoltaics, has become increasingly popular due to technological improvements, cost reductions, and favourable policies. Solar cells can now be made from a range of materials, including traditional multicrystalline silicon wafers, thin-film silicon cells, and organic semiconductors. While thin-film photovoltaics are cheaper to produce, crystalline silicon cells are more efficient at converting sunlight into electric current. The annual production of photovoltaics has been increasing by more than 25% per year for the past decade, with a remarkable 45% increase in 2005.

Wind power has also been experiencing rapid growth, with the worldwide generating capacity of wind turbines increasing by more than 25% annually over the past decade. In the United States, wind power capacity has increased by 36% in the last five years, and wind power is now the cheapest form of new electricity in many locations.

Biofuels, such as ethanol and plant-derived fuels, are also gaining traction. Ethanol, made from corn, currently dominates the market in the US, with a substantial tax credit supporting its manufacturers. However, there is ongoing research into the development of cellulosic ethanol, which is made from woody plants and has the potential to reduce greenhouse gas emissions by 90% or more.

According to the International Energy Agency (IEA), the world added 50% more renewable energy capacity in 2023 than in 2022. Solar photovoltaic accounted for three-quarters of these additions, with China leading the way. The IEA predicts that under existing policies, renewable power capacity will grow to 7,300 GW over the next five years, with solar and wind energy overtaking coal as the largest source of global electricity generation by early 2025.

While the expansion of renewable energy sources is encouraging, more needs to be done to reduce greenhouse gas emissions and combat climate change. Policymakers and citizens must work together to accelerate the transition to clean energy and address the challenges posed by economic growth and increasing energy demands.

The transition away from fossil fuels

One challenge to the transition is the argument that renewable energy sources will not be able to meet the energy demands of large countries. However, many countries are already operating on significant renewable energy sources, and nuclear energy, a low-carbon source, offers a potential solution to this issue. Additionally, renewable energy sources are constantly being innovated, making them more accessible and effective.

Another challenge is the argument that natural gas, a fossil fuel, is a necessary bridge fuel to meet net-zero emissions goals. While natural gas is cleaner than coal, it is still a significant contributor to greenhouse gas emissions and has been linked to serious environmental damage.

Overall, the transition away from fossil fuels is essential to mitigate the negative impacts of burning them and must be expedited to avoid catastrophic consequences for the planet.

The health impacts of burning fossil fuels

Fossil fuels, including coal, oil, and natural gas, have been key to industrialization and rising prosperity. However, their impact on health and the climate has led to a transition towards low-carbon energy sources. Burning fossil fuels has been linked to a range of adverse health effects, and it is important to understand these impacts to appreciate why a shift in energy sources is necessary.

Burning fossil fuels releases harmful pollutants into the atmosphere, including sulfur dioxide, nitrogen oxides, and particulate matter. These pollutants contribute to poor air quality, which can cause respiratory diseases and other respiratory disorders such as asthma. The pollutants can also form acid rain, which has negative consequences for aquatic ecosystems and freshwater sources. Additionally, the fine particulate matter from fossil fuel combustion has been linked to premature deaths, with vulnerable groups at the greatest risk. According to research, more than 8 million people died in 2018 from fossil fuel pollution, making it responsible for about one in five deaths worldwide.

The burning of fossil fuels also emits greenhouse gases, primarily carbon dioxide, which intensifies the greenhouse effect and leads to global warming. This, in turn, contributes to climate change, which has its own set of health impacts. Climate change increases the frequency and severity of extreme weather events, including wildfires, hurricanes, wind storms, flooding, and droughts. These events can directly harm human health and also impact essential sectors such as agriculture and water resources. Additionally, climate change can alter patterns of snow and ice melt, affecting local freshwater availability.
