Fossil fuels, including coal, oil, and natural gas, have been powering economies and human survival for over 150 years, currently supplying about 80% of the world's energy. They are considered non-renewable resources because they take millions of years to form through geological processes and known viable reserves are being depleted much faster than new ones are generated. Fossil fuel consumption has increased significantly over the past half-century, with global energy demand increasing by 2.1% in 2017, 72% of which was from fossil fuels. This has resulted in a dramatic rise in CO2 emissions, causing serious environmental damage and contributing to global warming and climate change. As low-carbon sources of energy become more readily available, the transition away from fossil fuels towards sustainable renewable energy sources is crucial to address the negative impacts of their consumption.

Fossil fuels are non-renewable resources
Due to the lengthy formation process, fossil fuels are considered non-renewable. While new fossil fuels are continually formed naturally, the rate of formation is significantly slower than the rate at which humans consume and deplete known reserves. This disparity between formation and consumption contributes to the classification of fossil fuels as non-renewable resources.
The consumption of fossil fuels has increased significantly over the past decades, with a roughly eight-fold increase since 1950 and a doubling since 1980. Coal, in particular, has been a critical energy source for centuries and continues to play a significant role in global energy production. However, it is also the most polluting energy source in terms of carbon dioxide emissions and local air pollution.
The large-scale burning of fossil fuels has severe environmental and health consequences. It is the primary source of greenhouse gas emissions, contributing to global warming, ocean acidification, and dramatic changes to Earth's climate. Additionally, the extraction and processing of fossil fuels, such as through strip mining, can destroy critical wildlife habitats and ecosystems, impacting both animal life and human health.
As a result of the negative impacts of fossil fuels, there is a growing movement to transition towards renewable and sustainable energy sources. While this transition may have significant economic consequences due to the heavy integration of the fossil fuel industry in the global economy, it is necessary to address the environmental and societal burdens associated with fossil fuel usage.

They are a major cause of climate change
Fossil fuels are a major cause of climate change. The burning of fossil fuels like coal, oil, and natural gas releases carbon dioxide (CO2) and other greenhouse gases into the atmosphere. These gases trap heat, leading to global warming and climate change. In 2022, over 70% of greenhouse gas emissions due to human activity were carbon dioxide released from burning fossil fuels.
Coal is the most carbon-intensive fossil fuel and produces the most CO2 and local air pollution per unit of energy. Oil and gas are also significant contributors to climate change and continue to grow in consumption. The production and use of fossil fuels also have environmental impacts beyond emissions. Activities such as mining, drilling, and waste disposal can destroy critical wildlife habitats and ecosystems, further contributing to climate change.
The Intergovernmental Panel on Climate Change (IPCC) has found that emissions from fossil fuels are the dominant cause of global warming. The average global temperature has already increased by 1°C, and warming above 1.5°C risks further sea level rise, extreme weather, biodiversity loss, and species extinction. To limit global warming, the IPCC warns that fossil fuel emissions must be halved within the next decade.
The transition away from fossil fuels towards renewable and sustainable energy sources is essential to mitigate climate change. However, this transition is expected to have significant economic consequences due to the heavy integration of the fossil fuel industry into the global economy. Nonetheless, the costs of continuing to rely on fossil fuels are immense, with air pollution from fossil fuels linked to millions of premature deaths each year.
In summary, fossil fuels are a major driver of climate change due to their high carbon content and the subsequent release of greenhouse gases when burned. The environmental and health impacts of fossil fuels are severe, and a rapid transition to low-carbon energy sources is necessary to address climate change and its associated risks.

Fossil fuels are a dominant energy source
Fossil fuels, including coal, oil, and natural gas, have been powering economies for over 150 years. In 2023, they accounted for 77% of primary energy consumption worldwide and over 60% of the electricity supply. Oil, coal, and gas currently serve about 80% of our energy needs, according to the U.S. Energy Information Administration.
The use of fossil fuels has been integral to human development. Peat, for instance, was used as a domestic fuel before recorded history. Coal was burned in early furnaces for metal ore smelting, while semi-solid hydrocarbons from oil seeps were used for waterproofing and embalming. The commercial exploitation of petroleum began in the 19th century, and fossil fuel consumption has increased significantly since then, particularly in the past half-century, with consumption doubling since 1980.
The burning of fossil fuels releases stored carbon and other greenhouse gases into the atmosphere. It is the largest driver of global climate change, causing dramatic changes to Earth's climate. Fossil fuels are also a major contributor to air pollution, which is linked to millions of premature deaths each year. In addition, the processes of unearthing, processing, and moving underground deposits of fossil fuels take a significant toll on our landscapes and ecosystems.
Despite the negative impacts of fossil fuels, they continue to be a dominant energy source due to their high energy density and the heavy integration of the fossil fuel industry into the global economy. The transition to renewable energy sources is expected to have significant economic consequences. However, it is important to rapidly transition away from fossil fuels towards low-carbon energy sources to mitigate the worst effects of climate change.

Fossil fuel extraction is harmful to the environment
Fossil fuels are considered non-renewable resources because they take millions of years to form and the known viable reserves are being depleted much faster than new ones are generated. The burning of fossil fuels has generated most of the energy required to propel our cars, power our businesses, and keep the lights on in our homes. Even today, oil, coal, and gas serve about 80% of our energy needs. However, fossil fuel extraction is harmful to the environment in several ways.
Firstly, fossil fuel extraction methods such as underground mining and strip mining can be extremely disruptive to the environment. Underground mining involves using heavy machinery to cut coal from deep underground deposits, while strip mining removes entire layers of soil and rock to access coal deposits. This can result in the destruction of large swaths of land, including forests and mountaintops, and the displacement of wildlife. Even after mining operations cease, the land may never recover its previous nutrient levels, and the remaining wildlife may suffer from habitat degradation and increased competition for resources.
Secondly, fossil fuel extraction can lead to water pollution and contamination. Oil spills and leaks during extraction or transport can pollute drinking water sources and endanger freshwater and ocean ecosystems. Fracking, a controversial extraction method, involves injecting water mixed with chemicals and sand at high pressure to release oil or gas, and this process can contaminate groundwater and drinking water with toxic substances such as arsenic, lead, chlorine, and mercury. Additionally, all drilling, fracking, and mining operations generate large volumes of wastewater, which can be laden with pollutants and endanger aquatic life if not properly contained and treated.
Thirdly, the extraction and use of fossil fuels contribute to air pollution. Fossil fuels emit harmful air pollutants even before they are burned, and the burning of fossil fuels releases greenhouse gases, particularly carbon dioxide (CO2), which is the largest driver of global climate change. In 2019, fossil fuels accounted for 74% of U.S. greenhouse gas emissions, and over 70% of global greenhouse gas emissions in 2022. This has led to ocean acidification, with about a quarter of the emitted carbon dioxide being absorbed by the oceans, altering their chemistry. Additionally, air pollution from fossil fuels can cause acid rain, eutrophication, damage to crops and forests, and harm to wildlife.
Lastly, the fossil fuel industry can have negative social and cultural impacts. It often requires leasing or seizing large areas of land, which can lead to the forced eviction of people from their homes and the destruction of cultural sites. Indigenous peoples are particularly and disproportionately affected by these land grabs, as much of the remaining fossil fuel deposits are situated on their land. Additionally, human rights defenders and climate activists who oppose the use of fossil fuels or stand up for environmental protection face repression, attacks, and intimidation from corporate and state actors.
