The Safest Source of Energy Will Surprise You
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) |
---|---|---|
Coal | 100,000 | 28.1% |
Oil | 36,000 | 31.7% |
Natural Gas | 4,000 | 21.6% |
Hydro | 1,400 | 2.5% |
Solar | 440* | <1% |
Wind | 150 | <1% |
Nuclear | 90 | 4.9% |
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: Renewable Energy and Battery Installations in the U.S. in 2023
This graphic describes new U.S. renewable energy installations by state along with nameplate capacity, planned to come online in 2023.

Renewable energy, in particular solar power, is set to shine in 2023. This year, the U.S. plans to get over 80% of its new energy installations from sources like battery, solar, and wind.
The above map uses data from EIA to highlight planned U.S. renewable energy and battery storage installations by state for 2023.
Texas and California Leading in Renewable Energy
Nearly every state in the U.S. has plans to produce new clean energy in 2023, but it’s not a surprise to see the two most populous states in the lead of the pack.
Even though the majority of its power comes from natural gas, Texas currently leads the U.S. in planned renewable energy installations. The state also has plans to power nearly 900,000 homes using new wind energy.
California is second, which could be partially attributable to the passing of Title 24, an energy code that makes it compulsory for new buildings to have the equipment necessary to allow the easy installation of solar panels, battery storage, and EV charging.
New solar power in the U.S. isn’t just coming from places like Texas and California. In 2023, Ohio will add 1,917 MW of new nameplate solar capacity, with Nevada and Colorado not far behind.
Top 10 States | Battery (MW) | Solar (MW) | Wind (MW) | Total (MW) |
---|---|---|---|---|
Texas | 1,981 | 6,462 | 1,941 | 10,385 |
California | 4,555 | 4,293 | 123 | 8,970 |
Nevada | 678 | 1,596 | 0 | 2,274 |
Ohio | 12 | 1,917 | 5 | 1,934 |
Colorado | 230 | 1,187 | 200 | 1,617 |
New York | 58 | 509 | 559 | 1,125 |
Wisconsin | 4 | 939 | 92 | 1,034 |
Florida | 3 | 978 | 0 | 980 |
Kansas | 0 | 0 | 843 | 843 |
Illinois | 0 | 363 | 477 | 840 |
The state of New York is also looking to become one of the nation’s leading renewable energy providers. The New York State Energy Research & Development Authority (NYSERDA) is making real strides towards this objective with 11% of the nation’s new wind power projects expected to come online in 2023.
According to the data, New Hampshire is the only state in the U.S. that has no new utility-scale renewable energy installations planned for 2023. However, the state does have plans for a massive hydroelectric plant that should come online in 2024.
Decarbonizing Energy
Renewable energy is considered essential to reduce global warming and CO2 emissions.
In line with the efforts by each state to build new renewable installations, the Biden administration has set a goal of achieving a carbon pollution-free power sector by 2035 and a net zero emissions economy by no later than 2050.
The EIA forecasts the share of U.S. electricity generation from renewable sources rising from 22% in 2022 to 23% in 2023 and to 26% in 2024.
