The World’s Safest Source of Energy Will Surprise You
When it comes to conversations on energy, it’s hard to leave your feelings at the door.
It’s arguable that energy is the single most important driver of human progress – it’s a multi-trillion dollar industry that powers our daily lives, technological advancements, and even the economic development of entire countries. At the same time, our choices around energy can have significant consequences. How we decide to generate energy can decimate the environment, fuel political conflicts, and even cause human deaths as unwelcome side effects.
The outcomes from our choices around energy are so vivid, that we’ve developed strong and polarized associations with the subject at hand.
The Empirical Perspective
Today’s visualization on the safest sources of energy comes to us from Cambridge House, the company hosting the International Mining Investment Conference 2018 on May 15-16 in Vancouver, BC, and it uses an empirical approach to compare different energy sources with one another.
Based on the data, this comparison provides a perspective that will be surprising to many viewers. Despite its perceived dangers, nuclear is actually the safest type of energy.
|Energy Source||Deaths per 1,000 TWh||% of Global Primary Energy Supply (2015)|
That’s right – even when including seemingly catastrophic incidents such as Chernobyl and Fukushima in the calculations, the math says that the amount of energy generated by nuclear is so vast that it more than outweighs these incidents over the long-term.
The reality is that nuclear energy is much more comparable to renewables like solar or wind, in terms of safety. More importantly, it’s on the polar opposite of the spectrum from coal, which manages to kill 4,400 people daily in China alone.
The Nuclear Option
Interestingly, multiple studies have come to this exact same conclusion, including the ones used in an analysis by economist Max Roser’s project called Our World in Data.
Even though the conclusion on nuclear is pretty cut and dry, it’s still hard to absorb. After all, the relative safety of nuclear ends up being extremely counter-intuitive to our human brains, which are seemingly wired to put more weight on big, memorable events (i.e. Chernobyl) rather than slow, consistent deaths that occur over time with other energy sources.
Today, nuclear provides about 11% of the world’s electricity from about 450 power reactors, generating about 2,500 TWh of electricity each year.
And while there are still questions that remain – specifically revolving around how to store certain types of nuclear waste – the above data explains why the majority of scientists classify nuclear as a sustainable and safe energy source, along with other renewables.

Mapped: The World’s Biggest Oil Discoveries Since 1868
Since 1868, there had been 1,232 oil discoveries over 500 million barrels of oil. This map plots these discoveries to reveal global energy hot spots.
Mapped: The World’s Biggest Oil Discoveries Since 1868
Oil and gas discoveries excite markets and nations with the prospect of profits, tax revenues, and jobs. However, geological processes did not distribute them equally throughout the Earth’s crust and their mere presence does not guarantee a windfall for whatever nation under which they lie.
Entire economies and nations have been built on the discovery and exploitation of oil and gas, while some nations have misused this wealth─or projected growth just never materialized.
The 20 Biggest Oil Discoveries
This map includes 1,232 discoveries of recoverable reserves over 500 million barrels of oil equivalent (BOE) From 1868 to 2010.
The discoveries cluster in certain parts of the world, covering 46 countries, and are of significant magnitude for each country’s economy. The average discovery is worth 1.4% of a country’s GDP today, based on the cash value from their production or net present value (NPV).
Of the total 1,232 discoveries, these are the 20 largest oil and gas fields:
|Field||Onshore/Offshore||Location||Discovery||Production start||Recoverable oil, past and future (billion barrels)|
|Ghawar Field||Onshore||Saudi Arabia||1948||1951||88-104|
|Mesopotamian Foredeep Basin||Onshore||Kuwait||n/a||n/a||66-72|
|Bolivar Coastal Field||Onshore||Venezuela||1917||1922||30-32|
|Safaniya Field||Offshore||Kuwait/Saudi Arabia||1951||1957||30|
|Upper Zakum Field||Offshore||Abu Dhabi, UAE||1963||1967||21|
|Romashkino Field||Onshore||Russia Volga-Ural||1948||1949||16-17|
|Shaybah Field||Onshore||Saudi Arabia||1998||1998||15|
|West Qurna Field||Onshore||Iraq||1973||2012||15-21|
Russia, West Siberia
The location of these deposits reveals a certain pattern to geopolitical flashpoints and their importance to the global economy.
While these discoveries have brought immense advantages in the form of cheap fuel and massive revenues, they have also altered and challenged how nations govern their natural wealth.
The Future of Resource Wealth: A Curse or a Blessing?
A ‘presource curse’ could follow in the wake of the discovery, whereby predictions of projected growth and feelings of euphoria turn into disappointment.
An oil discovery can impose detrimental consequences on an economy long before a single barrel leaves the ground. Ideally, a discovery should increase the economic output of a country that claims the oil. However, after major discoveries, the projected growth sometimes does not always materialize as predicted.
Getting from discovery to sustained prosperity depends on a number of steps. Countries must secure investment to develop a project to production, and government policy must respond by preparing the economy for an inflow of investment and foreign currency. However, this is a challenging prospect, as the appetite for these massive projects appears to be waning.
In a world working towards reducing its dependence on fossil fuels, what will happen to countries that depend on oil wealth when demand begins to dwindle?
Countries can no longer assume their oil and gas resources will translate into reliable wealth — instead, it is how you manage what you have now that counts.
Which Companies Are Responsible For the Most Carbon Emissions?
Since 1965, over ⅓ of the world’s cumulative carbon emissions can be traced back to just 20 fossil fuel companies. Who are the biggest contributors?
20 Companies Responsible For the Most Carbon Emissions?
Since 1965, it’s estimated over 1.35 million metric tons (MtCO₂e) of greenhouse gases have been released into the atmosphere—and over a third can be traced back to just 20 companies.
This week’s chart draws on a dataset from the Climate Accountability Institute, and highlights the companies which have been responsible for the most carbon emissions in the past half-century.
The Sum of their Carbon Emissions
Between 1965-2017, the top 20 companies have contributed 480,169 MtCO₂e in total carbon emissions, or 35% of cumulative global emissions. This whopping amount is mostly from the combustion of their products—each company on this chart deals in fossil fuels.
The largest contributor? Saudi Aramco, the national petroleum and natural gas company of Saudi Arabia. Saudi Aramco actually comes in first on another list as well—it’s the most profitable company, making over $304 million daily.
However, this financial gain came at a significant cost: the state-owned giant’s operations have resulted in 59,262 MtCO₂e in carbon emissions since 1965. To put that into perspective, this total is more than six times China’s emissions in 2017 alone (9,838 MtCO₂e).
Explore the full list of companies by location, who owns them, and their total 1965–2017 emissions count below:
|Company||Country||Ownership||All Emissions, MtCO₂e|
|Total Emissions||480,169 MtCO₂e|
|Saudi Aramco||🇸🇦 Saudi Arabia||State-owned||59,262|
|Exxon Mobil||🇺🇸 U.S.||Investor-owned||41,904|
|National Iranian Oil Co.||🇮🇷 Iran||State-owned||35,658|
|Royal Dutch Shell||🇳🇱 Netherlands||Investor-owned||31,948|
|Coal India||🇮🇳 India||State-owned||23,124|
|Petroleus de Venezuela||🇻🇪 Venezuela||State-owned||15,745|
|Peabody Energy||🇺🇸 U.S.||Investor-owned||15,385|
|Abu Dhabi National Oil Co.||🇦🇪 UAE||State-owned||13,840|
|Kuwait Petroleum Corp.||🇰🇼 Kuwait||State-owned||13,479|
|Iraq National Oil Co.||🇮🇶 Iraq||State-owned||12,596|
|Total SA||🇫🇷 France||Investor-owned||12,352|
|BHP Billiton||🇦🇺 Australia||Investor-owned||9,802|
A Greener Business Model?
According to the researchers, all the companies that show up in today’s chart bear some responsibility for knowingly accelerating the climate crisis even after proven scientific evidence.
In fact, U.S.-based Exxon Mobil is currently on trial for misleading investors: the company downplayed the effect of climate change on its profitability, while internal calculations proved to be much larger. It also sowed public doubt on the immense impacts of rising greenhouse gas levels on the planet.
Growing sustainability and environmental concerns threaten the viability of old business models for these corporations, causing many to pivot away from the fossil fuel focus. Take BP for example—originally named British Petroleum, the company embraced “Beyond Petroleum” as its new rallying cry. More recently, it launched a carbon footprint calculator and is committed to keeping its carbon emissions flat into 2025.

However, the Climate Accountability Institute argues that more can still be done, with the researchers calling for these companies to reduce their fossil fuel production in the near future.
Continued pressure on these “Big Oil” companies to peak their carbon emissions, and urgently increase their renewable energy investment, may help curb the climate crisis before it’s too late.
