After I finished writing the topic of cars, I was initially thinking of writing my personal opinion. The way the brush that writes the text of the car is getting heavier.
If you have other things you want to write, even if you try to write a sentence with different content, you will not feel comfortable.
That's why. I changed my schedule and wrote down what I wanted to write now. After being refreshed, I decided to write about the car.
Therefore, from here onward, the sentences are basically unrelated to the car. If you are not interested, judge the content by the title. I hope you can pass it through as it is.
Now. First of all, I would like to introduce a Twitter site that I trust as a source of information. This is Fire Maruyama's Twitter account, which runs a website called "FireRoadster".
https://twitter.com/fireroadster
When surfing the net every day for a change of pace and information gathering. I visit here almost every day to check for new posts.
But why. Information from a fairly wide range of fields is coming in and out. The quality of that information also feels quite high.
First of all, I would like to introduce "Information that caught my eye when I saw this Fire Maruyama-san's Twitter a while ago." First from the energy field.
... In addition, here, "Why is it a while ago, not the latest? I think there are many people who think that. That's because new information is being written more and more, and the saved links are quickly swept away into the past.
And after saving the link. It took me a while to get ready to start writing this sentence. If you try to add information from the time you saved the link to the latest, it will be quite a huge amount of content. I decided not to cover that much. Then, I will introduce it immediately.

『Another effective way to save gas is to restart the nuclear power plant. As Prime Minister Kishida insists, one nuclear power plant can save 1 million tons of LNG.
Again, the delay in restarting the nuclear power plant has had an impact. It's difficult to move immediately, but we have to get it up and running as soon as possible for the winter.』

『I really think so. There are no other countries other than Japan that say that there is a shortage of electricity, as 30 nuclear power plants have not been abolished. Similarly, Japan is the only country with the best clean coal-fired technology in the world to abolish coal. It's humorous』

『The timing of surplus sunlight is different in the daytime in spring and autumn, and the timing of tight supply and demand occurs in the evening when the output of sunlight decreases. The Nikkei newspaper also advocates "improvement of the power grid", but since the supply capacity itself is insufficient, there is no point in increasing the amount of power that can be accommodated. The idea of "actually surplus" has not made any progress from the reserves of the Democratic Party of Japan.』

『It is the Democratic Party's job to raise the consumption tax, stop the nuclear power plant, buy renewable energy at a bellows price higher than the electricity bill, and make the difference borne by the people.
The Re-Energy Law is a law formed by the Democratic Party of Japan and Kamuro Bank to make solar panel companies and investors in China and South Korea profitable. The burden is on the Japanese people. The people still bear the negative legacy』

『The reason why the construction of storage sites is not progressing in Japan is that pumped storage and gravity storage have overwhelmingly large storage capacity and are safer than using lithium batteries.』
『Mr. Jiro Shinbo, a solar believer, said, "Solar panels and storage batteries, etc.", but even this world's largest power storage facility in Tesla can only store 180,000 kW for 4 hours.
The required amount in the TEPCO jurisdiction is 30 million kW per hour even at midnight, so it is not a story.』

『Mr. Shinbo is still exploding the renewable energy fantasy today. Let's check the contents.
1. About installed capacity
It is a clear mistake to discuss renewable energy in terms of installed capacity. Considering efficiency, 10 to 20% (at kWh) would be a good place. It is the same expression as the nuclear power plant ○ machine. I can't count on more than the tabelog score』
『2. No power outage due to the amount of solar power generated
There is a time lag between the peak of solar power generation and the peak of power demand. In addition, it will fluctuate depending on the weather. Due to this backup, thermal power generation is forced to operate inefficiently. This leads to increased costs and CO2 emissions, which is wasteful.』
『Looking at this graph again, I feel that it is difficult to make the most of renewable energy. The amount of electricity generated by a solar panel depends on the solar altitude. In other words, the maximum is around 12:00 noon. On the other hand, the demand for air conditioners is related to temperature. In other words, there will be a time lag.』
『Mr. Shinbo has a grinning face and is pleased that 30% of the electricity is generated during the day, but this idea is the re-energy fantasy. It must be regarded as a problem if it is a normal idea that 30% of the power supply, which is expected to fluctuate with time and weather, enters.』
『It's like 10 million kw nuclear power plants operating irregularly😓
↓
On March 22, when the power supply and demand tight warning was issued, the power demand was 45 million kW, and the installed capacity of the registered solar power was 17.77 million kW, 39%. The peak value of sunlight is 14 million kW in fine weather, but 1.74 million kW in cloudy weather.』

『What are you saying.
After 11 years, power consumption has increased.
The TVs on sale now have a larger screen than 11 years ago and the resolution is 4k or 8K instead of 2k.
If it is the same inch, the panel aperture ratio will decrease as the resolution increases, so the backlight will be burned more.
If the image engine is 4k, the image processing is 4 times that of FHD, and if it is 8k, the image processing is 16 times, so the power consumption is increasing.』

『"There is no explanation as to why there was a sudden shortage of electricity." I was pointing out』
And, is it like this just by writing energy related?
What you have to be careful about is not to take the information you see as it is. Is the information provided here really correct? It is to read while thinking for yourself. I felt like I understood just by accepting the information I got. It is doubtful whether it will even become a baking blade if it is used without proper understanding and verification.
Instead of being swayed by a large amount of information, select the necessary information and put it in your hands. I want to be able to use it freely as a hand.
Well, that's about it for simply quoting the opinions of others. From here, I will write my thoughts.
The other day, I just read the material "About the outlook for electricity supply and demand in 2022 and countermeasures" published by the Agency for Natural Resources and Energy. This winter is going to be a terrible situation. The following is an image excerpted from the material.
First of all, the first one. If this winter becomes a severe cold in the class once every 10 years. Especially in the Tokyo area, the electricity supply capacity is expected to be short of about 2 million kW.
Next is the second image. When the Tokyo area runs out of electricity, I saw if it would be possible to get electricity from other areas. In the Tohoku area, which you would most like to rely on, the reserve margin for electricity is expected to be around 3.4%. It seems that there is very little spare capacity, if any, to accommodate the Tokyo area.
The central and Hokuriku areas are even more severe. It seems that there is not enough spare capacity to supply the route from the 60MHz zone such as Kansai to the interchange of 50MHz power through the converter. If this goes on, a large-scale power outage may occur in the Tokyo area this winter if no measures are taken. It seems possible to implement rolling blackouts to avoid that.
What is the KW open call for participants in the third image? When the power is about to run short, request the power company to supply the shortage of power. It means that the electric power company will generate more electricity than planned at its own free will.
In summary, "The soaring fuel prices have increased the cost of operating thermal power plants. By setting an upper limit on the electricity bill, the increase in the fuel price cannot be fully reflected in the electricity bill. I'm well aware that the more power you generate, the bigger the deficit will be. Still to prevent social turmoil. In the spirit of self-sacrifice, please be aware that further deficits will be added to your business performance, and please increase the amount of power generation. "
By the way. "Whether or not the open call for participants will be held will be decided immediately before it is certain that there will be a shortage of electricity. On top of that, it is up to the electric power company to decide whether or not to accept the public offering. The thermal power plant for generating additional power should be maintained under the individual judgment and responsibility of the power company. Of course, you are responsible for all maintenance costs. "
At the same time that the free entry of new power companies was lifted, existing power companies were released from supply obligations. Therefore, of course, there is an option not to bid even if the public offering is made. If you think that you should prepare for an emergency in the worst case. As shown in the figure, we must consider the possibility that a power shortage will actually occur with zero bids.
Given that the crisis could come just six months later. "From now on, we will start building a large number of large-scale thermal power plants, complete all of them in a short period of time, and half a year later, the kettle is already on fire, and we will stably generate enough power to make up for the power shortage. A solution like "I'm ready to supply" is impossible. However, if the nuclear power plant that is currently shut down is to be restarted additionally. It seems that it is not impossible to bring it to the start of power generation within half a year.
Looking back on the Fukushima nuclear accident caused by the Great East Japan Earthquake. Although the damaged nuclear power plant was very old. Despite being hit by such a big earthquake, the nuclear power plant was not damaged by the earthquake. Subsequent accidents were caused by the loss of backup power due to the tsunami and the suspension of cooling. In other words, if you make sure that even the backup power supply is maintained, even if a large earthquake occurs in the area where the nuclear power plant is located, the probability that it will lead to a nuclear accident is much lower than people think. Then? It can also be considered.
In the current situation, a serious power shortage may occur in just six months. In the future, even if we move toward the elimination of nuclear power, we will first overcome the immediate crisis. And to build a new power generation facility that can meet the electricity demand of society while gradually reducing the dependence on nuclear power plants. Should we use a nuclear power plant that can be used immediately if we feel like it, at least recently? I think.
And at the next stage. Overcoming the immediate power shortage, construction of new power plants (mainly thermal power?) Is progressing. Is it okay to start reducing the number of nuclear power plants in operation? When it came to the stage. How long will the fuel rods of a stopped nuclear power plant cool to a safe temperature? I checked. I searched and found the following Q & A.
https://detail.chiebukuro.yahoo.co.jp/qa/question_detail/q1398648288
『In both nuclear reactors and pools, there is a danger that heat will eventually build up and the fuel will melt when water cooling stops, but the time from when water cooling stopped until it melted was stored in water cooling from the stop of combustion (nuclear reaction) in the reactor. It changes depending on the period. If it is in a state immediately after stopping without a storage period, it will all melt in a few hours like Fukushima Daiichi Unit 1. If the storage period is about half a year, it will start to melt in about 3 days after the water cooling is stopped, and if it is 1 year, there is a margin of about 6 days. After about two years, it will hardly melt unless it is a closed space that is confined and has no air cooling (it seems that the temperature will be high enough to burn things).』
I referred to here. If you continue to cool it in water for about two years, even if the cooling stops due to the loss of power, there seems to be almost no concern that the fuel rods will melt.
Speaking forcibly. As a concrete example of "a closed space that is confined and has no air cooling," the inside of the containment vessel of a nuclear reactor comes to mind. It seems necessary to take it out and move it to the fuel pool.
Now, about the new power generation facilities that should be increased from now on. In addition to oil and natural gas, we should also consider reassessing traditional coal-fired power. Because the efficiency of Japan's coal-fired power plants is at the highest level in the world. The burden on the environment is also clearly lower than that of coal-fired power plants in other countries.
How efficient is it compared to other countries? With this kind of feeling, it is in a state of top running alone.
Not long ago, Western countries didn't notice this efficiency. He severely criticized Japan, which uses coal-fired power. However, the situation changed completely due to the crisis in Ukraine. It has become clear that the reason why EU countries have promoted "environmentally friendly renewable energy such as solar power" is that natural gas etc. was stably supplied from Russia. Germany, for example, is restarting coal-fired power plants that have been so criticized. (But for some reason, it seems that the nuclear power plant will be decommissioned as planned despite the lack of electricity.)
By the way, the story changes. There is such a line in my favorite manga "Wangan Midnight".
『For example, there are times in life that suddenly change to accelerate one day. It's time to see things that you couldn't see as your field of view widened as if you were going up the stairs at once.
... But there are many people who can't move at that time. Because he wasn't making himself at the time of the stagnant flow.
See the movement of people and move. This is often the case for people who live a passive way of thinking and a reaction.
Always sharpen your nails in preparation for the next step.
There is always a new flow behind the bad flow and the flow that you cannot ride.
Be aware of it, think about it, and believe it. Are you sharpening your nails?』
Even in the international situation, I feel that this is the time.
It has already been confirmed that the flow so far will change. Now is the time to read what's coming next and get ready for a new one.
If you want to insist on the opinion of nuclear power plant now. First of all, "Why and under what circumstances can a nuclear power plant be dangerous? Let's think about it. Then, at the same time, "Under what circumstances can the nuclear power plant be operated safely?" You can also see the condition.
If you want to build a new power plant to replace the nuclear power plant, you naturally need enough electricity to build it. Then, in order to obtain that power, it will be necessary to rely on the nuclear power plant in the immediate future of power shortage.
For example, nuclear power plants in areas that are unlikely to be hit by a major earthquake in the next 10 years will be restarted for only 7 years to eliminate the power shortage. And during those 7 years, we built as many new power plants as needed. Sequentially, it will be replaced with old thermal power plants and nuclear power plants that should have reached the end of their life.
Seven years later, the restarted nuclear power plant will be shut down. After that, for at least two years, prepare a perfect backup posture and cool the fuel rods with water cooling.
And at least 9 years. Just in case, I had to secure an extra cooling period for the fuel rods for an extra year, and finally I could spend 10 years safely. Since then, the temperature of the fuel rods has dropped sufficiently, so even if the power is lost due to a large earthquake, there is no risk of a meltdown.
With this kind of feeling, I made my thinking flexible and made full use of the cards I currently have. I personally think that we should think about the energy policy of the next era.
