5 Ways Nuclear Power Can Enable an Energy Utopia

The phrase Energy utopia describes a hypothetical and sustainable state of the world where energy is clean, affordable, and accessible. 

Despite the challenges on the road to achieving an energy utopia, such a state is attainable if the world invests in clean, reliable technologies that can meet our rising energy needs—and nuclear power is one such technology.

This infographic sponsored by CanAlaska Uranium explores five ways nuclear power can unlock a state of energy utopia. This is Part 2 of 4 in the Road to Energy Utopia series.

#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.
