Fossil fuels are the dominant energy source globally
Fossil fuels are formed over millions of years from the decomposition of organic material, such as ancient plants and animals, and compressed into dense deposits of carbon. This process occurs within geological formations in the Earth's crust. The resulting energy-dense fuel sources are incredibly productive, with a small amount of fossil fuel able to produce a substantial amount of energy. This quality has made them very attractive for human use, and their discovery led to a significant shift in energy consumption away from basic energy sources like human and animal muscle power and burning biomass.
The concentrated energy provided by fossil fuels has been challenging to replace with alternative energy sources. Their accessibility and reliability have been key factors in their continued dominance. Fossil fuels can be used anywhere the appropriate infrastructure exists and are not dependent on weather conditions or time of day, unlike solar or wind power. The infrastructure and technology required to extract and utilize fossil fuels are also well-established and widely available, making them a convenient choice.
However, the widespread use of fossil fuels has severe environmental consequences. The burning of fossil fuels releases large amounts of greenhouse gases, particularly carbon dioxide (CO2), which is the dominant cause of global warming and climate change. Fossil fuels also contribute to local pollution where they are produced and used, impacting the climate and health of our planet. Despite recognition of these negative effects and a push for renewable and sustainable energy, fossil fuels remain deeply integrated into the global economy and continue to play a dominant role in global energy systems.

The burning of fossil fuels began during the Industrial Revolution
Fossil fuels have been important to human development because they can be readily burned in the open atmosphere to produce heat. The burning of fossil fuels for energy began around the Industrial Revolution, which started in Britain in the late 18th century. The Industrial Revolution unlocked a new energy resource: fossil fuels. Fossil fuels (coal, oil, and gas) have played and continue to play a dominant role in global energy systems.
Before the Industrial Revolution, windmills and watermills provided the energy needed for work such as milling flour, sawing wood, or pumping water, while burning wood or peat provided domestic heat. The wide-scale use of fossil fuels, coal at first and petroleum later, in steam engines enabled the Industrial Revolution. The use of peat as a domestic fuel predates recorded history, and coal was burned in some early furnaces for smelting metal ores. Semi-solid hydrocarbons from oil seeps were also burned in ancient times, mainly for waterproofing and embalming. Commercial exploitation of petroleum began in the 19th century.
The Industrial Revolution brought about a shift from an organic economy, where people met their needs by harvesting energy and materials from the earth's surface ecosystems, to a mineral-intensive economy, where ancient stocks of energy were extracted from beneath the earth. This transformation was particularly dramatic in the industrial sector, with coal-powered technologies magnifying the strength, stamina, and precision of American workers, making the U.S. labor force the most productive in the world. However, the burning of fossil fuels has had severe consequences for the environment, with carbon emissions driving global warming and climate change.
Today, fossil fuel consumption has increased significantly, with oil and gas growing quickly, while coal consumption is falling in many parts of the world. Recognition of the climate crisis, pollution, and other negative effects caused by fossil fuels has led to a widespread policy transition and activist movement focused on ending their use in favor of renewable and sustainable energy.

Fossil fuel consumption has increased eight-fold since 1950
Fossil fuels have been a key driver of industrialization and technological, social, and economic progress. They were first utilized during the Industrial Revolution and have since played a dominant role in global energy systems. However, the widespread use of fossil fuels has severe environmental consequences, with their combustion being the largest contributor to global climate change.
Fossil fuel consumption has indeed increased significantly since 1950, with an eight-fold rise over the past seven decades. This surge in consumption is attributed to various factors, including the increasing energy demands of a growing global population and the intensification of energy-intensive economic growth models, particularly in Eastern Europe and Asia. The shift from solely relying on coal towards incorporating oil and natural gas into the energy mix has also influenced this trend.
The consumption of fossil fuels has not been consistent across all regions, with notable disparities between the largest and smallest consumer nations. For instance, the economic boom in Asia significantly contributed to the rise in global energy consumption, with this region's energy consumption doubling from 16% to 35% of the world's energy balance. Similarly, Eastern Europe's share of global energy consumption doubled from 10% to 20% during the same period, reflecting the energy-intensive nature of its economic growth model.
The production of fossil fuels has also witnessed significant changes since 1950, with substantial increases in coal, oil, and natural gas output. China, India, and Australia have been the primary drivers of growth in coal production, with China's unprecedented expansion since 2000 being particularly noteworthy. From 2000 to 2005, the world experienced the largest absolute increase in energy production, and fossil fuels accounted for nearly 92% of this increment.
While the consumption and production of fossil fuels have escalated since 1950, there is a growing recognition of the need to transition towards renewable and sustainable energy sources. The detrimental effects of fossil fuels on the environment and public health have prompted international policies and agreements, such as the United Nations' sustainable development goals and the Paris Climate Agreement, aimed at facilitating a global shift away from fossil fuels. Additionally, the COVID-19 pandemic caused a significant drop in the demand and price of oil, further highlighting the potential for reducing our reliance on fossil fuels.

Fossil fuels are the main cause of climate change
Fossil fuels are carbon-containing materials formed from the decomposition of prehistoric organisms. They are classified as non-renewable resources because they take millions of years to form, and known viable reserves are being depleted much faster than new ones are generated. The burning of fossil fuels releases carbon dioxide, a greenhouse gas that contributes to global warming and climate change.
The use of fossil fuels has been integral to human development, providing a convenient and concentrated form of energy. However, their impact on the environment and human health has led to a growing movement advocating for a transition to renewable and sustainable energy sources. Fossil fuels are the dominant cause of climate change, and their continued use is causing lasting harm to the planet's climate.
In 2023, fossil fuels accounted for 77% of primary energy consumption and over 60% of the electricity supply worldwide. The large-scale burning of fossil fuels has resulted in serious environmental damage, with over 70% of greenhouse gas emissions due to human activity in 2022 attributed to the release of carbon dioxide from burning fossil fuels. The average global temperature has already increased by 1°C, and global temperatures passed the critical 1.5°C milestone in 2024. This warming has led to rising sea levels, extreme weather events, biodiversity loss, species extinction, and food scarcity, impacting the lives of millions worldwide.
The transition away from fossil fuels is challenging due to their deep integration into the global economy and the concentrated energy they provide. However, the development of low-carbon energy sources and the growing awareness of the climate crisis are driving efforts to reduce fossil fuel consumption and transition to renewable alternatives.
To summarise, fossil fuels are the main cause of climate change due to their significant contribution to greenhouse gas emissions, particularly carbon dioxide. The widespread use of fossil fuels has resulted in severe environmental consequences, highlighting the urgent need for a transition to renewable and sustainable energy sources.

The transition away from fossil fuels will have economic consequences
Fossil fuels have been a fundamental driver of technological, social, and economic progress since the Industrial Revolution. They are still deeply embedded in the global economy and heavily subsidised, so transitioning away from them will have significant economic consequences.
Firstly, fossil fuels are major revenue sources for governments. Fossil fuels generate $138 billion annually for US governments, and these revenues are likely to decline even without new climate policies. Petroleum product taxes are the largest source of revenue and will decline under all scenarios. Changes to government tax policies can help replace declining revenue and help communities adapt.
Secondly, the transition will impact jobs. Solar and wind-based energy create more jobs than the oil and gas industry, but not in the exact locations and with different skill requirements, demanding retraining of the workforce.
Thirdly, the transition to low-carbon energy sources requires significant investment in new infrastructure and technology. While solar and wind technologies are proven and have progressed in their learning curves, the deployment of CO2 management technologies like CCS (Carbon Capture and Storage) and CCU (Carbon Capture and Utilization) faces challenges due to high investments and uncertain returns.
Finally, the transition may impact energy prices and security. Fossil fuels have provided reliable and affordable energy, and while renewable sources like solar and wind are becoming more competitive, they may not immediately provide the same level of energy security or price stability, especially in developing economies.
Overall, the transition away from fossil fuels is necessary to address climate change and local pollution. While it offers economic opportunities, it will also present economic challenges that need to be addressed through government policies, investments, and a just transition that considers the societal burdens created by the stranded assets of the fossil fuel industry.
