The following article was published on NHK on 2020/07/02.
The government has decided to make a major overhaul of coal-fired power generation. Adjustments have been made to reduce the amount of power generated by old coal-fired power plants, which emit a lot of carbon dioxide, by about 90% by FY2030.

In addition, by significantly reducing the dependence on coal-fired power, it will be an issue to review long-term energy policies including renewable energy and nuclear power in the future.Source: NHK
The above article is very good because it is about reducing coal-fired power generation, which produces CO2 that causes a climate crisis. However, if you look closely, you may not be happy.
To conclude first, there are two problems.
- Abolish 100 old coal-fired power plants, but actually maintain 26 coal-fired power plants with high efficiency and allow 16 new coal-fired power plants currently under construction, so even after 2030 It will allow more than 30 million kilowatts of operation. Developed countries must reduce coal-fired power to zero by 2030 at the latest in order to limit the temperature rise to 1.5 degrees Celsius, which is the goal of the Paris Agreement, but that is not enough.
- “By significantly reducing our reliance on coal-fired power, we will reassess our long-term energy policy, including nuclear power, to reduce the shortage of electricity.” This indicates that the government is considering restarting nuclear power plants.
First of all, 1. However, while the government says that it will reduce 90%, it is equivalent to saying that coal-fired power will continue to be used until 2030. This is a strange behavior that is unmoral in the world.
Furthermore, 2. Needless to say, the peaceful use of nuclear weapons is an illusion, and we should not use a system that cannot be stopped safely in the first place, and nuclear waste is already about 47 tons . (This is equivalent to about 6,000 nuclear bombs.), we shouldn’t leave any more debt in the future, so restarting the nuclear power plant is an unlikely option. (Japan is still under the “Nuclear Emergency Declaration” issued in 2011 and has not been lifted. The following is the scene of the removal work of the nuclear power plant PR signboard in Futaba Town, Fukushima Prefecture in 2015.)
First of all, there are premise that overuse of electricity, usage problems and old power grid, and it is necessary to improve it, but Japan is proud of the world’s best renewable energy technology (solar power, wind power, hydraulic power, tidal power, geothermal power, etc.). By making full use of them, I think that energy problems can be solved and it is possible to respond to the climate crisis without relying on coal, oil, or nuclear power plants.
