In 2015, a study revealed that household goods and services production and use were responsible for 60% of global greenhouse gas emissions. This figure highlights how deeply fossil fuels are embedded in our everyday lives, extending far beyond obvious sources like gasoline in our cars or electricity from coal-fired power plants. From the plastic toothbrush you use each morning to the polyester in your clothes and the packaging around your snacks, fossil fuels are hiding in plain sight. Many of these items are created using petrochemicals—crude oil and natural gas derivatives. Yet, public awareness remains low. One survey found that 44% of consumers were unaware that disposable water bottles are made from fossil fuel-based materials.
Understanding these connections is vital for making more sustainable choices. In this article, we will take a look at the surprising ways fossil fuels show up in daily life—and why this matters for our planet’s future.
What Are Fossil Fuels?
Fossil fuels are ancient energy sources formed from the remains of plants and animals that lived millions of years ago. Over time, heat and pressure transformed these remains into coal, oil, and natural gas. These fuels have powered our world for centuries, providing energy for electricity, transportation, and heating.
In 2023, fossil fuels accounted for approximately 81.5% of global primary energy consumption, with coal, oil, and natural gas being the primary sources. Coal is predominantly used for electricity generation, oil is refined into fuels like gasoline and diesel, and natural gas serves various purposes, including heating and electricity production.
Despite the growth of renewable energy, fossil fuel consumption reached record highs in 2023, driven by increased energy demand, particularly in developing economies. This reliance on fossil fuels has significant environmental implications, as their combustion releases greenhouse gases that contribute to climate change.
Everyday Examples of Fossil Fuel Use
1. Transportation
Gasoline and Diesel
Every day, many of us rely on vehicles powered by gasoline or diesel fuels derived from crude oil. Whether it’s commuting to work, running errands, or embarking on a road trip, these fossil fuels are integral to our daily lives. Beyond personal vehicles, air travel is a significant contributor to carbon emissions. According to the Air Transport Action Group (ATAG), in 2023, the aviation industry was responsible for approximately 2.05% of global CO₂ emissions, equating to 882 million tonnes of CO₂.
Even as electric vehicles (EVs) gain popularity, it’s essential to recognize that their production and operation still involve fossil fuels. Manufacturing EVs, particularly their batteries, can produce around 60% more CO₂ emissions compared to traditional gasoline vehicles, according to The Guardian. However, over their lifetime, EVs typically result in lower total emissions, especially as electricity generation becomes cleaner.
Public Transportation
Public transportation systems, such as buses and trains, have traditionally operated on diesel fuel. However, there’s a growing shift towards electrification. For instance, cities like Chicago have been integrating electric buses into their fleets since 2014, aiming for a completely electric fleet by 2040. While challenges like reduced battery range in cold weather exist, solutions like fast-charging stations are being implemented to address them.
Similarly, school buses, which are among the least efficient vehicles, are transitioning to electric power. Electric school buses not only reduce emissions but also offer benefits like lower maintenance costs and the potential to serve as mobile power sources during emergencies.
2. Electricity and Heating
Home Heating
In many parts of the world, particularly in colder climates, natural gas is a primary source for home heating. In the United States, for instance, about 46% of households rely on natural gas for space heating, making it the most common heating fuel nationwide, according to a report by EIA. Electricity follows closely, especially in the southern regions, while heating oil and propane are more prevalent in the Northeast and Midwest.
In Europe, countries like Germany have seen fluctuations in natural gas consumption. In 2023, Germany’s gas consumption decreased by approximately 5% compared to the previous year, influenced by milder temperatures and energy-saving measures. However, during colder months, the demand for natural gas for heating remains substantial.
Electricity Generation
When it comes to generating electricity, fossil fuels still hold a significant share globally. Coal and natural gas are often used to meet base-load and peak electricity demands. Even countries that have invested heavily in renewable energy sources sometimes rely on fossil fuels during periods when renewable output is low.
Take Germany, for example. According to a report by the German Federal Statistical Office (Destatis), in 2024, renewable energy sources accounted for nearly 60% of the country’s electricity production. However, during times of low wind and solar output, known as “Dunkelflaute,” Germany had to depend more on coal and natural gas to ensure a stable electricity supply. This reliance shows the challenges of transitioning entirely to renewable energy sources.
Moreover, in early 2025, Europe faced challenges in clean electricity generation due to reduced snow cover and declining wind output. To compensate, utilities increased fossil fuel usage, with gas-fired output rising by 26% and coal-fired output by 15% in the first quarter compared to the previous year.
3. Household Products
Plastics
Take a moment to look around your home. Chances are, many items within your reach—like food containers, remote controls, or even your toothbrush—are made of plastic. These plastics are derived from petrochemicals, which are chemicals obtained from petroleum and natural gas. They are processed into polymers that form the basis of countless household items. For instance, polypropylene and polyethylene are common plastics used in packaging, kitchenware, and toys.
However, the convenience of plastics comes with environmental and health concerns. A study by NYU Langone Health linked exposure to phthalates—chemicals used to make plastics flexible—to approximately 356,000 premature deaths globally in 2018, primarily due to heart disease. These chemicals are prevalent in many household items, including food containers and personal care products.
Synthetic Fabrics
The clothes we wear often have a hidden cost. Synthetic fabrics like polyester, nylon, and spandex are made from petrochemicals. Polyester, in particular, has become the most widely used fiber in the fashion industry, accounting for 57% of global fiber production in 2023.
Producing these synthetic fibers is energy-intensive and relies heavily on fossil fuels. Moreover, washing synthetic clothes releases microplastics into waterways, contributing to ocean pollution. An estimated 35% of the microplastics found in the ocean originate from washing synthetic fabrics.
Personal Care Products
Many personal care items, such as shampoos, lotions, and cosmetics, contain ingredients derived from petroleum. For example, mineral oils and certain alcohols used in these products are petrochemical derivatives. These substances are included for their moisturizing properties and to improve texture and shelf life.
However, some of these chemicals, like phthalates, have been associated with health risks. Phthalates are used to stabilize fragrances and increase the flexibility of plastics in packaging. Exposure to certain phthalates has been linked to hormonal disruptions and other health concerns.
4. Food and Agriculture
Fertilizers and Pesticides
Modern farming heavily relies on synthetic fertilizers, particularly nitrogen-based ones produced through the Haber-Bosch process. This method uses natural gas to convert nitrogen from the air into ammonia, a key component in fertilizers. Remarkably, this process consumes about 3–5% of the world’s natural gas production and contributes to approximately 450 million tons of CO₂ emissions annually, comparable to the total emissions of South Africa.
Pesticides and herbicides often contain petroleum-based chemicals to enhance their effectiveness. These additives, known as crop oils, are derived from paraffin or naphtha-based petroleum and help pesticides adhere better to plants. However, their use raises environmental concerns, including potential soil and water contamination
Food Transportation and Packaging
Beyond the fields, fossil fuels continue to play a role in processing, packaging, and transporting our food. Plastic packaging materials are typically made from petroleum derivatives. Transporting food, especially perishable items, often requires refrigerated trucks powered by diesel engines. These refrigeration units can account for up to 40% of a truck’s total CO₂ emissions. Moreover, the global food cold chain is responsible for about 4% of total greenhouse gas emissions, equivalent to the emissions of the entire continent of Africa, according to the Food and Agriculture Organization (FAO).

| Transportation | Diesel-powered trucks; refrigeration units |
| Storage | Electricity for refrigeration and lighting |
| Home Use | Plastic bags; cooking with gas stoves |
5. Digital World and Technology
Data Centers
Every time we stream a video, send an email, or use cloud storage, data centers process and store that information. These facilities are energy-intensive, consuming about 4.4% of total U.S. electricity in 2023, with projections suggesting this could rise to between 6.7% and 12% by 2028.
Despite advancements in renewable energy, a significant portion of electricity still comes from fossil fuels. According to the EIA, in 2023, approximately 60% of U.S. electricity generation came from coal, natural gas, and petroleum. This reliance contributes to greenhouse gas emissions and environmental concerns.
Electronics Manufacturing
The devices we use daily—smartphones, laptops, tablets—are products of complex manufacturing processes that heavily rely on fossil fuels. From mining raw materials to assembling components, each step consumes energy, often sourced from coal, oil, or natural gas.
Semiconductor manufacturing, a critical part of electronics production, is particularly energy-intensive. In 2023, Taiwan Semiconductor Manufacturing Company (TSMC) used about 25,000 gigawatt-hours of energy, with a significant portion derived from fossil fuels. Moreover, the global semiconductor industry is projected to consume 237 TWh of electricity by 2030, equivalent to the entire electricity consumption of Australia in 2021.
The Environmental Cost
Burning Fossil Fuels releases greenhouse gases like carbon dioxide (CO₂), methane (CH₄), and nitrous oxide (N₂O), which trap heat in our atmosphere and drive climate change. In 2023, atmospheric levels of CO₂ and CH₄ reached record highs, with CO₂ averaging 419.3 parts per million and CH₄ at 1922.6 parts per billion, marking significant increases from pre-industrial levels.
The environmental impact doesn’t stop there. Burning fossil fuels also releases nitrogen oxides and sulfur dioxide, leading to the formation of smog and acid rain. These pollutants degrade air quality and harm ecosystems. Moreover, excess nitrogen from these emissions can wash into water bodies, causing harmful algal blooms and creating oxygen-deprived zones that are deadly for aquatic life.
The human health implications are equally alarming. According to the World Health Organization, outdoor air pollution, much of it stemming from fossil fuel combustion, is responsible for approximately 4.2 million premature deaths each year. These pollutants contribute to respiratory diseases, cardiovascular conditions, and other serious health issues.
In response to these challenges, regulatory measures are being implemented. For instance, the U.S. Environmental Protection Agency has finalized rules requiring existing coal-fired power plants and new gas-fired plants to achieve a 90% reduction in greenhouse gas emissions by 2032. These steps are crucial in mitigating the environmental and health impacts of fossil fuel use.
Why We Still Rely on Fossil Fuels
Infrastructure Lock-In
Our cities, industries, and transportation networks are designed around fossil fuels. From the gas stations on every corner to the power plants lighting our homes, these systems are built to run on coal, oil, and gas. The International Energy Agency warns that if current fossil fuel infrastructure continues operating as is, it could lock us into a path exceeding global warming targets, making the 1.5°C goal increasingly elusive.
Economic Interests
In 2022, global fossil fuel subsidies soared to a staggering $7 trillion, equivalent to 7.1% of the world’s GDP. These subsidies, both explicit and implicit, make fossil fuels artificially cheap, reinforcing their dominance in the market. This financial entanglement makes transitioning to cleaner energy sources a daunting economic challenge.
Energy Density
Fossil fuels deliver a remarkably high energy output. Take gasoline, for example—it has an energy density of about 13,100 watt-hours per kilogram (Wh/kg), making it exceptionally efficient for powering vehicles and machinery where compact, portable energy is crucial. This high density means that small volumes can deliver a lot of energy, which is one reason fossil fuels have dominated transportation and industry for decades. Renewable sources like solar and wind, while cleaner, have lower energy densities and require more space and infrastructure to produce the same amount of energy.
