Fossil fuels have been our predominant source of energy for over a century, and the world still extracts and consumes a colossal amount of coal, oil, and gas every year. This infographic visualizes the volume of global fossil fuel production in 2021 using data from BP’s Statistical Review of World Energy.
The Facts on Fossil Fuels
In 2021, the world produced around 8 billion tonnes of coal, 4 billion tonnes of oil, and over 4 trillion cubic meters of natural gas.
Most of the coal is used to generate electricity for our homes and offices and has a key role in steel production. Similarly, natural gas is a large source of electricity and heat for industries and buildings. Oil is primarily used by the transportation sector, in addition to petrochemical manufacturing, heating, and other end uses.
Here’s a full breakdown of coal, oil, and gas production by country in 2021.
Coal Production
If all the coal produced in 2021 were arranged in a cube, it would measure 2,141 meters (2.1km) on each side—more than 2.5 times the height of the world’s tallest building. China produced 50% or more than four billion tonnes of the world’s coal in 2021. It’s also the largest consumer of coal, accounting for 54% of coal consumption in 2021. India is both the second largest producer and consumer of coal. Meanwhile, Indonesia is the world’s largest coal exporter, followed by Australia. In the West, U.S. coal production was down 47% as compared to 2011 levels, and the descent is likely to continue with the clean energy transition.
Oil Production
In 2021, the United States, Russia, and Saudi Arabia were the three largest crude oil producers, respectively. OPEC countries, including Saudi Arabia, made up the largest share of production at 35% or 1.5 billion tonnes of oil. U.S. oil production has seen significant growth since 2010. In 2021, the U.S. extracted 711 million tonnes of oil, more than double the 333 million tonnes produced in 2010.
Natural Gas Production
The world produced 4,036 billion cubic meters of natural gas in 2021. The above graphic converts that into an equivalent of seven billion cubic meters of liquefied natural gas (LNG) to visualize it on the same scale as oil and gas. Here are the top 10 producers of natural gas in 2021: The U.S. was the largest producer, with Texas and Pennsylvania accounting for 47% of its gas production. The U.S. electric power and industrial sectors account for around one-third of domestic natural gas consumption. Russia, the next-largest producer, was the biggest exporter of gas in 2021. It exported an estimated 210 billion cubic meters of natural gas via pipelines to Europe and China. Around 80% of Russian natural gas comes from operations in the Arctic region. on
#1: High Reliability
Nuclear power plants run 24/7 and are the most reliable source of sustainable energy. Nuclear electricity generation remains steady around the clock throughout the day, week, and year. Meanwhile, daily solar generation peaks in the afternoon when electricity demand is usually lower, and wind generation depends on wind speeds.As the use of variable solar and wind power increases globally, nuclear offers a stable and reliable backbone for a clean electricity grid.
#2: Clean Electricity
Nuclear reactors use fission to generate electricity without any greenhouse gas (GHG) emissions.Consequently, nuclear power is the cleanest energy source on a lifecycle basis, measured in CO2-equivalent emissions per gigawatt-hour (GWh) of electricity produced by a power plant over its lifetime. The lifecycle emissions from a typical nuclear power plant are 273 times lower than coal and 163 times lower than natural gas. Furthermore, nuclear is relatively less resource-intensive, allowing for lower supply chain emissions than wind and solar plants.
#3: Stable Affordability
Although nuclear plants can be expensive to build, they are cost-competitive in the long run. Most nuclear plants have an initial lifetime of around 40 years, after which they can continue operating with approved lifetime extensions. Nuclear plants with lifetime extensions are the cheapest sources of electricity in the United States, and 88 of the country’s 92 reactors have received approvals for 20-year extensions. Additionally, according to the World Nuclear Association, nuclear plants are relatively less susceptible to fuel price volatility than natural gas plants, allowing for stable costs of electricity generation.
#4: Energy Efficiency
Nuclear’s high energy return on investment (EROI) exemplifies its exceptional efficiency. EROI measures how many units of energy are returned for every unit invested in building and running a power plant, over its lifetime. According to a 2018 study by Weissbach et al., nuclear’s EROI is 75 units, making it the most efficient energy source by some distance, with hydropower ranking second at 35 units.
#5: Sustainable Innovation
New, advanced reactor designs are bypassing many of the difficulties faced by traditional nuclear plants, making nuclear power more accessible.
Small Modular Reactors (SMRs) are much smaller than conventional reactors and are modular—meaning that their components can be transported and assembled in different locations. Microreactors are smaller than SMRs and are designed to provide electricity in remote and small market areas. They can also serve as backup power sources during emergencies.
These reactor designs offer several advantages, including lower initial capital costs, portability, and increased scalability.
A Nuclear-Powered Future
Nuclear power is making a remarkable comeback as countries work to achieve climate goals and ultimately, a state of energy utopia. Besides the 423 reactors in operation worldwide, another 56 reactors are under construction, and at least 69 more are planned for construction. Some nations, like Japan, have also reversed their attitudes toward nuclear power, embracing it as a clean and reliable energy source for the future.
