What You'll Learn
Fossil fuels' contribution to climate change
Fossil fuels—including coal, oil, and natural gas—have been powering economies for over 150 years, currently supplying about 80% of the world's energy. The burning of fossil fuels releases large amounts of carbon dioxide and other greenhouse gases into the atmosphere. Greenhouse gases trap heat in the atmosphere, causing global warming and climate change. The average global temperature has already increased by 1°C, and global temperatures passed the critical 1.5°C milestone in 2024. 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.
The transportation sector, including road, rail, air, and marine transportation, accounts for 15% of global greenhouse gas emissions, with almost all (95%) of the world's transportation energy coming from petroleum-based fuels. The power sector, including electricity and heat production, is the largest single source of global greenhouse gas emissions, accounting for 34% of emissions. The industrial sector contributes 24% of emissions, primarily from fossil fuels burned on-site at facilities for energy, as well as chemical, metallurgical, and mineral transformation processes.
Fossil fuel companies are huge polluters, producing and selling fossil fuel products while scientists advocate for a mass switch to renewable energy. Oil and gas production is growing quickly, and global coal production is expected to double by 2030, despite commitments made by governments in the Paris Agreement to reduce carbon emissions. The future of oil is uncertain as economies transition towards sustainable renewable energy sources such as hydropower, biomass, wind, geothermal, and solar energy.
The burning of fossil fuels has negative impacts beyond climate change and global warming. It contributes to air and water pollution, with coal-fired power plants generating dangerous mercury and sulfur dioxide emissions, as well as particulate matter that contributes to smog and respiratory illnesses. Fossil fuel-powered vehicles emit poisonous carbon monoxide and nitrogen oxide. Additionally, fossil fuels are used to create plastics and chemicals, which have further environmental and health impacts.

The economic costs of fossil fuels
Fossil fuels have been a fundamental driver of technological, social, economic, and development progress throughout most of human history. However, the economic costs of fossil fuels are significant and are expected to increase over time.
Firstly, fossil fuels impose substantial environmental costs, which in turn have economic implications. Fossil fuel combustion is the leading contributor to global warming, which poses a range of economic risks. For example, rising sea levels and more severe storms could result in costly damage to key cities, with a potential price tag of $422 billion in damages between 2025 and 2100 for Atlantic and Gulf Coast states. Global warming is also predicted to cause declining rainfalls and rising temperatures, leading to extended droughts and impacting public health, with heat-related illnesses, increased ozone smog, and vector-borne diseases. An assessment by former World Bank Chief Economist Sir Nicholas Stern estimated that global warming could reduce global per-capita consumption by up to 20%. The economic cost of air pollution in sectors regulated under the Clean Air Act has been estimated at $9 trillion between 1970 and 2000, with costs arising from early mortality, illness, healthcare expenses, and lost productivity.
Secondly, there are direct economic costs associated with the purchase and consumption of fossil fuels. In the United States, American consumers and businesses spent an estimated $700 billion to $1 trillion annually on coal, oil, and natural gas. In 2006, this figure was $921 billion, or approximately 7% of America's gross domestic product, exceeding the country's spending on education or the military.
Thirdly, the transition away from fossil fuels will impact government revenues. Between 2015 and 2020, fossil fuels generated approximately $138 billion each year for US localities, states, tribes, and the federal government. As the energy market shifts towards clean energy, these revenue streams are expected to decline, presenting fiscal challenges for governments and communities heavily reliant on the fossil fuel industry.
Finally, the health costs of air pollution and climate change due to fossil fuels are significant. More than half of US adults report medical financial hardship, and the health costs of air pollution and climate change exceed $800 billion per year, with this figure likely to increase.
Overall, the economic costs of fossil fuels are extensive and encompass environmental damage, direct costs to consumers and businesses, government revenue losses, and health expenses. Addressing these economic costs and transitioning towards cleaner energy sources is crucial to mitigate the financial and societal impacts of fossil fuel usage.

Transitioning to a clean energy economy
Fossil fuels have been a fundamental driver of technological, social, and economic progress since the Industrial Revolution. Oil and gas are among the most important commodities in the world, with the oil and gas industry being one of the largest industries globally. In 2019, the energy sector, including oil and gas, employed over 41 million people worldwide. Oil and gas exploration and production make up a large portion of the global economy, and the growth of this industry is expected to increase in the future.
However, burning fossil fuels is the main cause of climate change and has several negative impacts. Fossil fuels produce carbon dioxide (CO2) when burned, making them the largest driver of global climate change. They are also a major contributor to local air pollution, which is linked to millions of premature deaths each year. As low-carbon sources of energy, such as nuclear and renewables, become more readily available, the world needs to rapidly transition away from fossil fuels to mitigate the worst effects of climate change.
The clean energy transition refers to the process of shifting energy production from sources that release greenhouse gases, such as fossil fuels, to those that release little to no greenhouse gases, such as wind, solar, hydropower, biomass, geothermal, and nuclear energy. This transition is gradual and complex, requiring significant infrastructure development, technological advancements, and policy changes.
To accelerate the transition to clean energy, several actions can be taken:
- Shift subsidies from fossil fuels to renewable energy: Redirecting subsidies from fossil fuels to renewable energy will help cut emissions, promote sustainable economic growth, create jobs, improve public health, and foster more equality, especially for vulnerable communities.
- Increase investments in renewable energy: At least $4 trillion per year needs to be invested in renewable energy until 2030 to reach net-zero emissions by 2050. This includes investments in technology, infrastructure, and supply chain development.
- Expand access to renewable energy components: Widespread access to key components and raw materials for renewable energy technologies, such as wind turbines, electricity networks, and electric vehicles, is essential. This will require significant international coordination and manufacturing capacity expansion.
- Improve energy efficiency: Enhancing the energy efficiency of buildings, vehicles, industrial processes, appliances, and equipment is the most immediate and cost-effective way to reduce energy use and emissions.
- Promote sustainable transportation: Orienting cities and towns around public transit, walking, and biking, instead of private vehicles, helps reduce energy demand and emissions.
- Carbon capture and storage (CCS): Carbon emitted by the fossil fuel sector can be collected and injected back into the earth through CCS. While this technology does not justify the continued burning of fossil fuels, it can help mitigate the worst effects of climate change.
By transitioning to a clean energy economy, we can address climate change, reduce air pollution, improve public health, create new job opportunities, and drive inclusive economic growth.

Fossil fuels' role in the Industrial Revolution
Fossil fuels have played a significant role in the Industrial Revolution, which began in the 18th century in northwest England. The burning of fossil fuels, such as coal, oil, and natural gas, provided an abundant and inexpensive source of energy that powered this revolution. This energy source was a departure from the basic forms of energy that humanity had relied on for most of its history, such as human and animal muscle power, biomass burning, and wind and water energy.
The Industrial Revolution marked a transformation from an agrarian economy to an industrial one, and fossil fuels were key facilitators of this shift. They enabled the development of innovative machines, such as the steam engine, which drove industrialization and economic progress. This engine also facilitated rapid urbanization, leading to overcrowded cities and various social issues. However, it played a pivotal role in the creation of large-scale transportation networks, enhancing trade and communication.
The abundance of fossil fuels, particularly coal, during the Industrial Revolution, led to the creation of engines and other machines. This development accelerated change and continues to transform human society. Fossil fuels provided the energy needed for large-scale manufacturing and infrastructure development, enabling the emergence of new technologies and the increased mechanization of production processes. They also played a crucial role in lighting and heating homes, improving the quality of life and living standards.
The use of fossil fuels has had, and continues to have, significant environmental impacts. When burned, they release carbon dioxide (CO2), making them the largest contributor to global climate change and local air pollution. The excessive release of carbon dioxide has led to global warming and other adverse environmental effects. Additionally, the finite nature of fossil fuels means they are non-renewable resources, formed over millions of years and unable to be replaced within a human lifetime.
While fossil fuels have played a dominant role in global energy systems, there is a growing trend towards transitioning away from them. Low-carbon energy sources, such as nuclear and renewable options, are becoming more readily available and offering cleaner alternatives. Countries are adopting strategies to develop low-carbon and carbon-free technologies, and renewable energy sources like hydropower, biomass, wind, geothermal, and solar energy are increasingly contributing to the energy mix.

The future of fossil fuels
Fossil fuels, including coal, oil, and natural gas, have been the primary energy source for economies worldwide for over 150 years, currently supplying about 80% of the world's energy. However, the future of fossil fuels is uncertain as the world transitions to sustainable renewable energy sources.
The burning of fossil fuels releases carbon and other greenhouse gases into the atmosphere, leading to dramatic changes in Earth's climate. To mitigate this, there is a growing trend towards renewable energy sources such as hydropower, biomass, wind, geothermal, and solar energy. Nuclear energy is another zero-carbon alternative, but it is expensive and leaves behind long-lasting radioactive waste.
According to a report by the ETC, fossil fuels could still represent 60% of primary energy consumption by 2040, with coal being phased out in the power sector and oil being concentrated in transport use. However, to meet a 2°C objective and limit global warming, a significant decrease in fossil fuel use is necessary. Carbon capture and sequestration technologies will play a crucial role in reducing emissions, but they do not eliminate the need to reduce fossil fuel consumption.
Despite the growing adoption of renewable energy, global fossil fuel production and consumption are still increasing. This is partly due to the rising power demand in developing countries, artificial intelligence data centers, and the need for cooling in a warming world. However, the UN has warned that countries clinging to fossil fuels are heading down a dangerous path, as renewable energy becomes more cost-effective and competitive.
In conclusion, the future of fossil fuels is likely to involve a gradual decline in their use as the world transitions to renewable energy sources. While fossil fuels have been a dominant energy source for centuries, the need to address climate change and the increasing cost-effectiveness of renewables are driving a shift towards more sustainable alternatives. The pace of this transition will be crucial in determining the future trajectory of our climate and energy systems.
