But for now, crude oil is still the undisputed heavyweight champion of the energy world. In 2018, we consumed more oil than any prior year in history – about 99.3 million barrels per day on a global basis. This number is projected to rise again in 2019 to 100.8 million barrels per day.
The Most Oil Reserves by Country
Given that oil will continue to be dominant in the energy mix for the short and medium term, which countries hold the most oil reserves? Today’s map comes from HowMuch.net and it uses data from the CIA World Factbook to resize countries based on the amount of oil reserves they hold. Here’s the data for the top 15 countries below: Venezuela tops the list with 300.9 billion barrels of oil in reserve – but even this vast wealth in natural resources has not been enough to save the country from its recent economic and humanitarian crisis. Saudi Arabia, a country known for its oil dominance, takes the #2 spot with 266.5 billion barrels of oil. Meanwhile, Canada and the U.S. are found at the #3 (169.7 billion bbls) and the #11 (36.5 billion bbls) spots respectively.
The Cost of Production
While having an endowment of billions of barrels of oil within your borders can be a strategic gift from mother nature, it’s worth mentioning that reserves are just one factor in assessing the potential value of this crucial resource. In Saudi Arabia, for example, the production cost of oil is roughly $3.00 per barrel, which makes black gold strategic to produce at almost any possible price. Other countries are not so lucky:
Even if a country is blessed with some of the most oil reserves in the world, it may not be able to produce and sell that oil to maximize the potential benefit. Countries like Canada and Venezuela are hindered by geology – in these places, the majority of oil is extra heavy crude or bitumen (oil sands), and these types of oil are simply more difficult and costly to extract. In other places, obstacles are are self-imposed. In some countries, like Brazil and the U.S., there are higher taxes on oil production, which raises the total cost per barrel. 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.
