Fossil fuels are a depleting resource, and the world's demand for energy is only increasing. In 2020, fossil fuels provided over 80% of the world's energy, with global energy consumption growing by 2.3% in 2018, nearly twice the average rate of growth since 2010. While renewable energy sources are on the rise, contributing a quarter of the world's energy demand in 2017, fossil fuels remain a critical component of the world's energy supply. According to estimates, the world has between 50 and 61 years of oil reserves left, around 150 years of coal reserves, and about 50 years of natural gas supply remaining, based on current consumption rates. However, these estimates do not account for potential increases in consumption or the discovery of new reserves.

What You'll Learn
Fossil fuel consumption trends
Fossil fuel consumption has increased significantly over the past 50 years, with consumption doubling since 1980 and increasing eightfold since 1950. Fossil fuels have been key to industrialization and rising prosperity, but they also have significant negative impacts on health and the climate.
The consumption of fossil fuels has been shifting from coal towards a combination of oil and gas. In 2020, coal supplied 19% of US energy consumption, a decrease from previous years, and this trend is expected to continue as coal-fired electricity plants are retired. Oil production and consumption also decreased in 2020 due to the COVID-19 pandemic, but they are expected to return to pre-pandemic levels in the coming years.
Despite these decreases, fossil fuels still supply about 80% of the world's energy. In 2023, fossil fuels accounted for about 84% of total US primary energy production, with petroleum, natural gas, and coal being the main sources. In the same year, about 60% of electricity generated at utility-scale electricity generation facilities in the US was from fossil fuels.
There are growing efforts to transition away from fossil fuels towards renewable energy sources. Technologies like hydropower, biomass, wind, geothermal, and solar energy are becoming a growing part of the energy mix in the US and other countries. Additionally, improving energy efficiency in buildings, vehicles, and industrial processes is an important way to reduce fossil fuel consumption and cut emissions.

Fossil fuel production by country
The United States is the world's largest producer of fossil fuels, contributing 20% of all global fossil fuel production. Within the US, Texas and Pennsylvania account for 47% of its gas production. In 2021, the US produced over 934 billion cubic meters of natural gas, despite ranking fifth in terms of proved natural gas reserves. The US was also the largest producer of crude oil in 2021, extracting 711 million tonnes of oil, more than double the amount produced in 2010.
Russia is the second-largest producer of fossil fuels and the biggest exporter of natural gas in 2021. It exported an estimated 210 billion cubic meters of natural gas to Europe and China. Russia, along with the US, is also one of the top 5 countries for natural gas exports and oil exports.
Following Russia, Iran is the third-largest producer of fossil fuels globally. Canada produces just under 5% of all fossil fuels globally, placing it fourth in the rankings.
In 2021, India was the second-largest producer and consumer of coal, while Indonesia was the world's largest exporter of coal, followed by Australia. China has also maintained its production of coal despite a decrease in its energy mix, with coal use remaining steady in absolute terms.

Fossil fuel reserves
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 ancient plants and animals. When burned, fossil fuels release their stored carbon and other greenhouse gases into the atmosphere, contributing to global warming and climate change. Despite the urgent need to transition to cleaner energy sources, fossil fuels still dominate the global energy system.
In 2023, fossil fuels accounted for 82% of the global energy mix, with oil and coal as the most significant contributors. This was a slight increase from the previous year, indicating that fossil fuel consumption is rising. The transportation sector is a major driver of oil consumption, while coal is used primarily for electricity generation.
According to the 2015 Paris Agreement, global warming needs to be limited to well below 2 °C, with efforts to restrict the increase to 1.5 °C. To achieve this, a sharp decline in fossil fuel use is necessary. By 2050, nearly 60% of oil and fossil methane gas reserves, and 90% of coal reserves, must remain unextracted to stay within the 1.5 °C carbon budget. This means that oil and gas production must decline by 3% annually until 2050, rendering many existing and planned fossil fuel projects unviable.
It is important to distinguish between "proven reserves" and "resources" of fossil fuels. Proven reserves refer to those that can be reasonably recovered with current economic and technological capabilities, while resources include potential future discoveries and quantities that may become extractable with technological advancements. As we continue to discover new fossil fuel sources and improve extraction technologies, the amount of proven reserves can change over time.

Fossil fuel alternatives
Fossil fuels are non-renewable resources formed millions of years ago. They include natural gas, coal, and oil, and our reserves are emptying quickly. According to BP, the world has 53 years of oil reserves left at the current rate of consumption. Other sources estimate that oil deposits will be depleted much earlier, with some saying by 2052 and others by 2060. The exact date is unknown, but it is clear that fossil fuels will run out.
The good news is that there are several fossil fuel alternatives that can help us transition to a more sustainable future. These alternatives include renewable energy sources, such as solar, wind, and hydro power, as well as nuclear power, hydrogen, biomass, and geothermal energy.
Solar energy harnesses sunlight to generate electricity through photovoltaic (PV) panels or concentrated solar power (CSP) systems. It is renewable, abundantly available, and reduces direct emissions and energy costs. However, solar energy is dependent on sunlight and has substantial installation costs and space requirements.
Wind energy uses wind turbines to convert wind power into electricity. Like solar energy, it is renewable, clean, and doesn't produce direct emissions. However, it depends on variable wind patterns and may have visual and land impacts.
Hydrogen is another alternative fuel, particularly for heavy transport such as ships, trucks, and aircraft. However, it relies on existing supplies of energy for its creation. Nuclear power is also an alternative that provides carbon-free electricity 24 hours a day. Uranium, which is required for nuclear power, may last over 150 years, but thorium-based nuclear reactors are being touted as the future of energy due to thorium's abundance in nature.
Biomass, which is biological material that is either living or decaying, can be used to reduce emissions from coal-fired plants. However, burning biomass still produces greenhouse gases. Geothermal power harnesses the Earth's natural sources of heat, such as volcanic activity, and provides 30% of Iceland's electricity. However, it is restricted to areas with volcanic sources.
While the world is still largely dependent on fossil fuels, the development and increasing affordability of these alternatives offer a promising path towards reducing our environmental impact and lowering fuel prices.

Fossil fuel environmental impact
Fossil fuels—coal, oil, and natural gas—have significant environmental and health costs. Burning fossil fuels releases large amounts of carbon dioxide, a greenhouse gas, into the atmosphere. This contributes to global warming and climate change. In 2023, carbon dioxide emissions from fossil fuels rose by 1.1% compared to 2022 levels, reaching a record high of 36.8 billion metric tons. This increase impedes progress towards limiting global warming.
The burning of fossil fuels also results in air pollution, releasing harmful pollutants such as nitrogen oxides, sulfur dioxide, particulate matter, carbon monoxide, and mercury. These pollutants contribute to the formation of smog and acid rain, damage crops and forests, harm wildlife, and have negative impacts on human health. Fossil fuel pollution is linked to various health issues, including asthma, cancer, heart disease, and premature death. Globally, it is responsible for one in five deaths, with communities of color and low-income communities disproportionately affected.
The extraction and production of fossil fuels also contribute to environmental issues. Drilling, fracking, and mining operations generate large volumes of wastewater, which can be contaminated with heavy metals, radioactive materials, and other pollutants. This wastewater can leak into waterways, contaminating drinking water sources and groundwater. Additionally, oil spills and the use of fracking fluids can cause water pollution, further damaging aquatic ecosystems.
To address these environmental and health impacts, a transition towards low-carbon energy sources, such as nuclear and renewables, is necessary. Embracing clean energy alternatives can help reduce air pollution, mitigate climate change, and improve public health outcomes.

Frequently asked questions
Fossil fuels are a depleting resource, and while it is difficult to put an exact date on when they will run out, it is estimated that at our current rate of consumption, they will be depleted by 2060.
According to sources, there are 49,023 exajoules of proven fossil fuel reserves. At current rates of consumption, this amounts to a 50-year supply of energy. However, this does not account for unproven reserves, which could potentially double the amount of fossil fuel energy available for extraction.
The US is one of the top producers of fossil fuels, particularly coal, which the country is still actively mining. While it is difficult to say exactly when the US will stop using fossil fuels, the country is also developing renewable energy sources, such as solar, wind, and hydro power.
