Fossil fuels have been the primary source of energy for most of human history, and they continue to play a dominant role in global energy systems. The burning of fossil fuels has been a fundamental driver of technological, social, and economic progress. However, it has also had a significant negative impact on the environment, with carbon dioxide emissions reaching an all-time high in recent years. While there has been a shift towards renewable energy sources, fossil fuels still account for a large portion of the world's energy consumption. This raises the question: how much of the world's total fossil fuel reserves have been extracted and used, and what are the implications for the future of energy consumption?

What You'll Learn
Fossil fuels still supply most of the world's energy
Fossil fuels have been the dominant source of energy globally for centuries, and they continue to play a significant role today. In 2023, fossil fuels comprised around 82% of the global energy mix, with coal, oil, and natural gas being the primary contributors. This percentage equates to a historic high in terms of global primary energy consumption, which increased by 1.5% from 2022.
The consumption of fossil fuels has seen a notable increase over the past decades, with an eight-fold increase since 1950 and a doubling since 1980. While coal consumption is decreasing in many parts of the world, oil and gas consumption continue to grow. In 2019, oil remained the most produced form of energy, and fossil fuels accounted for over 81% of production.
The United States, the world's third-largest consumer of coal, provides an illustrative example of the continued dominance of fossil fuels. In 2023, fossil fuels accounted for about 84% of the country's primary energy production, with petroleum, natural gas, and coal being the main sources. While renewable energy production and consumption in the US reached record highs in 2023, comprising about 9% of total primary energy production and consumption, it is evident that fossil fuels continue to dominate the energy landscape.
Despite the growing adoption of renewable energy sources, the world still has a long way to go before they become the primary source of energy. In 2023, clean energy sources accounted for only 15% of the world's energy mix, with solar and wind making up 8% of that total. The transition towards renewable energy sources has been described as not having "even started" by industry experts.
The COVID-19 pandemic caused a brief interruption in fossil fuel consumption, particularly in the transport sector, where demand for oil decreased significantly. However, as economies rebounded and demand increased, fossil fuel consumption resumed its upward trajectory.

Fossil fuel consumption has increased
Fossil fuel consumption has been increasing over the past half-century, with an eight-fold increase since 1950 and a doubling since 1980. In 2023, fossil fuel consumption reached a record high, increasing by 1.5% from 2022, with coal, oil, and natural gas comprising 82% of the global energy mix. This increase in consumption led to a record 40 gigatonnes of carbon dioxide (CO2) emissions, up 2% from 2022.
The rise in fossil fuel consumption has been driven by a spike in energy demand, with more than half coming from the Global South, where energy demand is growing at twice the global rate. Despite a record rise in renewable energy use in 2023, consumption of fossil fuels continued to increase. This trend is particularly evident in developing countries, which are increasing their reliance on coal, gas, and oil as overall energy demand rises.
While some countries, such as the United States and those in Europe, have seen a decrease in fossil fuel consumption, others like China and India are leading the way in coal consumption, with China burning more coal than the rest of the world combined. India's fossil fuel consumption climbed by 8% last year, matching the increase in overall energy demand and surpassing the combined consumption of Europe and North America.
The burning of fossil fuels has significant negative impacts, including the production of carbon dioxide (CO2) and contributing to global climate change and local air pollution. As low-carbon sources of energy, such as nuclear and renewables, become more readily available, it is crucial for the world to rapidly transition away from fossil fuels to mitigate their harmful effects on the environment and human health.

Coal is the most polluting energy source
Coal is an abundant fuel source that is relatively inexpensive to produce and convert into useful energy. However, it is also the most polluting energy source. In 2022, CO2 emissions from burning coal for energy accounted for about 19% of total US energy-related CO2 emissions and about 55% of total CO2 emissions from the electric power sector. Coal is a solid, carbon-heavy rock that comes in four main varieties: lignite, sub-bituminous, bituminous, and anthracite. All coal is dirty and carbon-intensive, regardless of its variety.
The process of extracting coal is extremely detrimental to the environment. Coal extraction methods include underground mining, which uses heavy machinery to cut coal from deep underground deposits, and surface mining (also known as strip mining), which removes entire layers of soil and rock to access coal deposits. Strip mining is particularly destructive, uprooting and polluting entire ecosystems. In the US, surface mines were the source of about 63% of the coal mined in 2022. Mountaintop removal and valley fill mining have also affected large areas of the Appalachian Mountains in West Virginia and Kentucky. This type of coal extraction involves removing the tops of mountains with explosives, changing the landscape and polluting streams with rock and dirt.
The burning of coal emits toxic and carcinogenic substances into the air, water, and land, severely affecting the health of miners, workers, and surrounding communities. In the US, air pollution from coal-fired power stations contributes to four of the five leading causes of mortality: heart disease, cancer, stroke, and chronic respiratory diseases. In 2013, 366,000 deaths in China were attributed to coal, while coal kills about 169,000 people annually in India. In Australia, coal's health impacts cost taxpayers an estimated $2.4 billion every year, causing health problems such as higher rates of childhood asthma, heart and lung disease, and some cancers.
Despite the drawbacks of coal, it has been a critical energy source and a mainstay in global energy production for centuries. However, the development of cleaner and cheaper alternatives, such as natural gas, renewables, and energy-efficient technologies, has made coal less economically attractive. As a result, demand for coal has been steadily declining since 2014, with coal-fired power plants continuing to close. Investments in clean energy have also been outstripping investments in fossil fuels, with renewables on track to become a cheaper source of energy than fossil fuels.

Fossil fuel production is declining
Fossil fuel production is an important metric that helps us understand where fossil fuels are being extracted and consumed. While fossil fuels have been a critical energy source and a mainstay in global energy production for centuries, there is a growing need to transition away from them due to their negative impact on health and the climate.
In recent years, there has been a decline in fossil fuel production, particularly in the case of coal. Coal has long been a dominant fuel for power generation, but its share of power production has been decreasing as renewables gain traction. In 2020, there was a significant drop in the production of fossil fuels, with a 5% decrease compared to 2019. This decline was driven by decreases in the production of oil (-7%) and coal (-4%), while natural gas production also decreased by 3%.
The shift away from coal is evident in many parts of the world. For example, in the United States, coal consumption has decreased, and in 2019, renewable energy consumption surpassed coal consumption for the first time. This decrease in coal consumption, along with a decrease in petroleum consumption, has contributed to an overall decline in fossil fuel consumption in the United States.
While fossil fuel production is declining, it is important to note that the consumption and production of oil and natural gas are still growing in many regions. In 2019, oil remained the most produced form of energy, and non-OECD Asia, non-OECD Europe, Caucasus, and Central Asia all increased their energy production. However, the growth of renewables and low-carbon sources of energy, such as nuclear power, is positive from a climate perspective.
To achieve the goal of reducing global warming and keeping Earth's temperature from exceeding pre-industrial levels, a significant reduction in fossil fuel consumption is necessary. This can be achieved by improving energy efficiency, reducing subsidies on fossil fuels, imposing carbon taxes, and transitioning to low-carbon energy sources. While the supply of fossil fuels is currently abundant, the world needs to rapidly transition away from them to mitigate their impact on climate change and human health.

Clean energy sources are increasing
Fossil fuels have been the dominant energy source for most of human history, but clean energy sources are increasingly becoming a viable alternative. Fossil fuels (coal, oil, and gas) have played a significant role in global energy systems, but they also contribute to climate change and air pollution. As of 2019, fossil fuels accounted for more than 80% of global energy production. However, this figure has been decreasing as renewable energy sources become more prevalent.
Renewable energy, also known as clean energy, is derived from natural sources that are constantly replenished, such as the sun, wind, water, waste, and heat from the Earth. These sources emit little to no greenhouse gases or pollutants, helping to address climate change and improve air quality. The use of renewable energy is expanding, with solar and wind generation breaking records and being integrated into national electricity grids. In 2019, renewable energy consumption in the United States surpassed coal consumption for the first time.
The transition to clean energy is being driven by technological innovations that have made capturing and retaining wind and solar energy more efficient and cost-effective. For example, the expansion of renewables is happening at various scales, from large offshore wind farms to rooftop solar panels on homes. Even entire rural communities are relying on renewable energy for heating and lighting. Additionally, there are other types of clean energy sources beyond wind and solar, such as nuclear energy, hydroelectric energy, and geothermal energy.
The growth of the clean energy industry has economic benefits, creating new job opportunities and stimulating the economy. It also reduces our dependence on fossil fuels, which are vulnerable to geopolitical shocks. According to the World Health Organization (WHO), about 99% of people worldwide breathe air that exceeds healthy air quality limits, with air pollution causing approximately 13 million deaths each year. By switching to clean energy sources, we can mitigate the effects of climate change, reduce environmental harm, and improve public health.
While the cost of solar and wind power is expected to remain high in the near term due to elevated commodity and freight prices, their competitiveness is improving due to the sharper increases in gas and coal prices. As renewable energy sources become more accessible, affordable, and reliable, they will play an increasingly important role in displacing fossil fuels and powering a safer, cleaner, and more sustainable future.
