No energy is perfect. Fossil fuels are the leading contributors to climate change, renewable energy is inconsistent, and nuclear energy is often viewed as dangerous due to catastrophes. The challenge is not to find the perfect energy source; instead, it is to find a solution that balances protecting the environment with sustaining our energy demands.
Despite the controversies in which it has been embroiled, nuclear power has low carbon emissions and can be scaled up to meet modern society’s needs, without intensifying the climate crisis. Yet it continues to be evaluated asymmetrically compared to fossil fuels and renewable alternatives.
Nuclear energy is one the most efficient form of energy production ever developed creating reliable and consistent energy throughout the year.
The astonishing fact is that nuclear power emits less radiation into the environment compared to any other primary energy source, while Coal is the major source of radioactive releases.
While wind, solar, and hydro also have low emissions, they are dependent on external environmental factors, which make them far less reliable.
In the United States in 2016, nuclear power plants had an average capacity factor of 92.3 percent, meaning they operated at full power on 336 out of 365 days per year. By contrast, U.S. hydroelectric systems delivered power 38.2 percent of the time, wind turbines delivered power 34.5 percent of the time, and solar electricity arrays delivered power only 25.1 percent of the time.
This is the flaw with renewables: they are inconsistent, and power grids need consistency. Thus, renewables need to work in conjunction with another energy source, such as nuclear or coal power. While we know that nuclear is more environmentally friendly than coal, do we know which one is safer?
Surprisingly, nuclear energy is far safer than coal, as global mortality studies indicate that nuclear energy is associated with only 0.03 deaths per terawatt-hour of electricity, compared to 24.6 for coal and 18.4 for oil, according to Our World In Data.
The safety of nuclear energy has long been perceived by the public as dangerous due to accidents like Chernobyl, Fukushima, and Three Mile Island, all resulting either from negligence or natural disasters. Although experts have learned from these mistakes, the public remains skeptical.
When weighed against the accelerating urgency of climate mitigation, the decision becomes clear: avoiding nuclear power increases dependence on the very fuels driving the crisis.
Nuclear energy is not a perfect solution, but statistically, it is far safer for humans and the environment than the fossil fuels we still rely on; therefore, it needs to work in tandem with renewable energy to enable us to meet global energy demands while protecting the planet.
Moreover, public opinion should no longer rule nuclear energy policy. Reliable nuclear energy means a healthy climate, a robust power grid, and a secure future. The climate clock is ticking, and nuclear offers a way out of crisis.
