COP 28: Is nuclear is sustainable energy?

During the COP 28, the international climate summit, more than 20 countries declared to triple their nuclear energy capacity by 2050 to reduce carbon emissions.

Is carbon emission the cause of global warming?

Recently it looks like oversimplifying the cause of global warming.
Carbon dioxide is the bad guy. However, we should ask if it is true.

Why does CO2 increase?
Our production and consumption of goods emit gas and heat.

Why do we produce and consume a lot?
Because we always aim for “economic growth”.
This mind model is the root cause of global warming.

Is nuclear power sustainable?

We had a tragic experience in Fukushima in 2011.
In addition, even if it operates safely, produces nuclear waste all the time and keeps it safe for more than a thousand years.

On January 1st, 2024, another big earthquake struck Noto Peninsula, the central Japan.

There is the biggest nuclear power plant(Kashiwazaki-Kariwa) near the disaster location.

We tend to focus on short-term economic profit however, now is the time to use systems thinking to formulate a long-term strategy.

  1. Hi Mr Tsuboi!
    How are you?
    Hope you are fine, and your family also!
    Nuclear energy has many advantages, including very low greenhouse gas emissions and year- round availability.
    However, it is also important to take into account its disadvantages such as radioactive waste management.
    Nuclear energy does not produce carbon and helps reduce anthropogenic greenhouse emissions which are responsible for global warming as well as local air pollution.
    For this reason that is interesting to preserve the possibility of recovering spent fuel, thus transforming it from a waste into a ressource.
    Because that this type of fuel cycle would make it possible to maximize the value of a unit of thorium or natural uranium, much lower grade ores could become profitable.
    Nuclear energy could thus become a long term energy source that could satisfy a large part of the growing global demand for energy. This recycling contributes to further increase
    productivity and total resources efficiency and thus the objectives of sustainable development.

    1. Thank you for your comment.

      Most people think like you.
      I respect your opinion.
      Your country plans to build a nuclear power plant in 2027.
      So,discussion is important.:)

      I wrote an article about our experience and risks as below;
      “Ten years after nuclear disaster”

      BBC also wrote a similar article in 2020;
      “How to build a nuclear warning for 10,000 years”

      Those articles will help you to think more about this matter.

      We have to keep nuclear waste safe for thousands of years.
      I want to avoid passing this trouble to the next generation.
