Fossil fuels, including coal, oil, and natural gas, have been the world's primary energy source for over 150 years. They are formed from the carbon-rich remains of prehistoric plants and animals, which decomposed and were compressed and heated underground over millions of years. Fossil fuels are burned to release energy, powering machinery, transportation, and electricity generation. Oil, for example, is used to create fuel for cars and is a key component in plastics. Coal is used to generate electricity and produce steel. However, burning fossil fuels releases carbon and other greenhouse gases, contributing to climate change. As a result, there is a growing transition towards low-carbon and renewable energy sources.

What You'll Learn
Fossil fuels are burned to generate electricity
Fossil fuels, including coal, oil, and natural gas, have been the world's dominant energy source for over 150 years, currently supplying about 80% of the world's energy. They are formed over millions of years from the carbon-rich remains of dead plants and animals.
Burning fossil fuels is an inexpensive method of generating electricity due to the ease of extraction, transport, and storage. The infrastructure required to extract, transport, and use fossil fuels already exists, making them a reliable and cost-effective energy source.
However, burning fossil fuels releases carbon dioxide (CO2) and other greenhouse gases, contributing to global climate change. It also produces pollutants such as nitrogen oxides and sulfur dioxide, which can lead to acid rain and have negative impacts on the environment and human health. As low-carbon energy sources become more accessible, the world is transitioning away from fossil fuels towards sustainable renewable energy alternatives.

Fossil fuels are refined to create fuel for transportation
Fossil fuels have been a key source of energy for economies for over 150 years, currently supplying about 80% of the world's energy. They are formed from the carbon-rich remains of prehistoric plants and animals, which are subjected to immense heat and pressure over millions of years. When burned, fossil fuels release the stored carbon and other greenhouse gases into the atmosphere, contributing significantly to climate change.
Oil, coal, and natural gas are the primary fossil fuels used, with oil constituting about one-third of US energy consumption. The transportation sector accounts for most oil consumption, with gasoline and diesel being refined from crude oil to power automobiles, trucks, railways, and aircraft.
Crude oil must be separated into its individual hydrocarbon-based fuels and lubricants to be used in transportation. This process involves refining the oil to create fuel oil, gasoline, and liquefied petroleum gas. The refined oil is then used as fuel to propel vehicles, aircraft, and other means of transportation.
In addition to transportation, fossil fuels are also used for heating, lighting, and cooking. They play a significant role in electricity generation, with coal being the largest domestically produced source of energy in America. However, there are negative environmental impacts associated with the extraction, processing, and distribution of fossil fuels, including air and water pollution, and the release of greenhouse gases.
As a result, there is a growing movement towards adopting alternative energy sources, such as renewable energy, and improving energy efficiency to reduce the demand for fossil fuels.

Fossil fuels are used to create non-fuel products like plastics
Fossil fuels—including coal, oil, and natural gas—have been used to power economies and everyday life for over 150 years, currently supplying about 80% of the world's energy. They are used for electricity, heating, and transportation. However, there is a growing need to transition to low-carbon energy sources due to the negative environmental impact of fossil fuels, particularly their contribution to global climate change.
While fossil fuels are primarily associated with energy production, they are also used to create non-fuel products, such as plastics. In fact, the majority of plastic is made from hydrocarbons derived from crude oil, natural gas, and coal, which are all fossil fuels. This process involves refining the oil to obtain various chemicals, which are then converted into monomers like ethylene, propylene, and butene. These monomers contain double bonds, allowing the carbon atoms to react and form polymers through a process called polymerization. The polymerization process generates thick, viscous substances known as resins, which are used to make plastic products.
The connection between the fossil fuel and plastic industries is deep-rooted. For instance, the shale gas boom in the United States has fueled the expansion of plastic infrastructure, with the potential to increase global plastic production capacity significantly in just a few years. This surge in plastic production undermines efforts to address the growing plastic pollution crisis. Plastic pollution has severe environmental consequences, as burning plastic releases climate-damaging emissions, and burying it contributes to the creation of toxic leachate that seeps into the soil and groundwater.
It is important to recognize that our reliance on fossil fuels for energy and non-fuel products, such as plastics, has significant environmental implications. As we transition to more sustainable energy sources, it is also crucial to explore alternatives to fossil fuel-derived plastics and reduce our overall plastic consumption to mitigate the negative impacts on our planet.

Fossil fuels are a source of energy for industrial processes
Fossil fuels, including coal, oil, and natural gas, have been a dominant energy source for industrial processes for over 150 years. They are non-renewable resources that formed from the carbon-rich remains of prehistoric plants and animals, which were compressed and heated underground over millions of years.
The burning of fossil fuels releases stored carbon and greenhouse gases, contributing significantly to climate change. Despite this, they continue to play a significant role in global energy systems, powering economies and industries. For example, natural gas is commonly used in industrial processes to generate heat or electricity. In 2020, natural gas supplied about one-third of U.S. energy consumption and was the largest source of energy-related carbon emissions in the country.
Oil, another fossil fuel, is also a major source of energy for industrial processes. It is used to create fuel oil, gasoline, and liquefied petroleum gas, which are essential for transportation and powering vehicles. Oil combustion accounted for 45% of U.S. energy-related carbon dioxide emissions in 2020, highlighting its environmental impact.
Coal, while declining in usage due to the rise of natural gas and renewable energy, still plays a role in industrial processes. It is primarily used for electricity generation and supplied 19% of U.S. energy consumption in 2020. The shift away from coal is driven by its high carbon dioxide emissions and the decreasing competitiveness of its costs compared to alternative energy sources.
While fossil fuels have been key to industrialization and technological progress, there is a growing recognition of their negative impacts on health, the environment, and the climate. As a result, there is a global transition towards renewable and sustainable energy sources, such as hydropower, biomass, wind, geothermal, and solar energy. This transition is supported by international policies and agreements, such as the United Nations' Sustainable Development Goals and the Paris Climate Agreement.

Fossil fuels are used to create heat energy for homes
Fossil fuels, including coal, oil, and natural gas, have been used to power economies and everyday life for over 150 years. They are formed from the carbon-rich remains of plants and animals that decomposed and were compressed and heated underground over millions of years.
The challenge of transitioning to cleaner energy sources is a significant one, as it involves replacing millions of fossil fuel furnaces and improving energy efficiency in buildings. Electrifying the residential sector is particularly tricky, as it requires a shift in public understanding and behaviour, as well as addressing the environmental and safety risks associated with extracting and transporting oil and other fossil fuels.
However, the transition away from fossil fuels is crucial to mitigating climate change and reducing carbon emissions. Technologies are being developed to reduce carbon emissions and ensure fossil energy sources can play a role in a clean energy future, such as carbon capture and storage (CCS) plants, which collect and inject carbon back into the earth. Additionally, researchers have developed a new catalyst for turning CO2 into fuel, offering a cheaper and more effective alternative to current methods.
