The world is in the middle of the first energy crisis of the 21st century. High energy prices, especially for oil, gas, and coal, are driving decades-high inflation in various countries, some of which are also experiencing energy shortages. Russia’s recent invasion of Ukraine has exacerbated the crisis, given that the country is both a major producer and exporter of oil and natural gas. Using data from BP’s Statistical Review of World Energy, the above infographic provides further context on the crisis by visualizing the world’s largest oil producers in 2021.
Oil Production: OPEC Countries vs. Rest of the World
Before looking at country-level data, it’s worth seeing the amount of oil the Organization of Petroleum Exporting Countries (OPEC) produces compared to other organizations and regions. The OPEC countries are the largest oil producers collectively, with Saudi Arabia alone making up one-third of OPEC production. It’s also important to note that OPEC production remains below pre-pandemic levels after the organization reduced its output by an unprecedented 10 million barrels per day (B/D) in 2020. Following the OPEC countries, the U.S., Canada, and Mexico accounted for just over a quarter of global oil production in 2021. Nearly 70% of North American oil production came from the U.S., the world’s largest oil producer. Similarly, within the CIS—an organization of post-Soviet Union countries—Russia was by far the largest producer, accounting for 80% of total CIS production.
The Largest Oil Producers in 2021
Roughly 43% of the world’s oil production came from just three countries in 2021—the U.S., Saudi Arabia, and Russia. Together, these three countries produced more oil than the rest of the top 10 combined. Over the last few decades, U.S. oil production has been on a rollercoaster of troughs and peaks. After falling from its 1970 peak of 11.3 million B/D, it reached a historic low of 6.8 million B/D in 2008. However, following a turnaround in the 2010s, the country has since surpassed Saudi Arabia as the largest oil producer. As of 2021, though, the U.S. remained a net importer of crude oil while exporting refined petroleum products. Saudi Arabia and Russia each produced roughly 11 million B/D in 2021 and were the two largest oil exporters globally. In both countries, state-owned oil firms (Saudi Aramco and Gazprom, respectively) were the most valuable oil and gas producing companies. From Europe (excluding Russia), only Norway made the top 15 oil producers, accounting for 2.3% of global production. The lack of regional output partly explains the European Union’s dependence on Russian oil and gas, worsening the region’s energy crisis.
How the Energy Crisis is Affecting Oil Production
After a deep dive in 2020, oil demand is resurfacing and is now above pre-pandemic levels. Furthermore, supply constraints due to sanctions on Russian oil and gas tighten the market and support high oil prices. While the impact has been felt globally, European countries have been hit hard due to their reliance on Russia’s fossil fuel exports, with some getting almost all of their energy fuels from Russia. To combat the oil crunch, the rest of the world is ramping up oil supply through increased production or releasing strategic petroleum reserves (SPRs). U.S. oil production is expected to rise by 1 million B/D in 2022 to a record-high. Simultaneously, Western nations are calling on OPEC members to increase their output to ease prices. However, OPEC nations are sticking to their planned production hikes, with output still below early 2020 levels. The U.S. is releasing 180 million barrels of oil from its SPR, of which 60 million barrels will contribute to the IEA’s collective release of 120 million barrels. But with oil demand expected to reach a new all-time high in 2023, it remains to be seen whether these efforts to increase supply will be enough to curb the crunch. 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.
