Atsushi Murakami's lecture contained information that many people should know about.

Yesterday, it was late at night and I was getting off the train, so I couldn't summarize the contents of my lecture.
I couldn't. It's a really wonderful thing, and I want as many people as possible to know about it.
I would also like to share with you some of the things that made a lasting impression on me so that I can keep them as a memorandum for myself.
I think that I want to do it.
Now, the decision on 0% or 15% etc. is approaching on the energy issue, but
It was all stuff that was rarely discussed in the media.
I'll list them below. (These are my own opinions and some comments from other speakers.)
・When we think of energy strategies, we tend to focus on how we generate electricity, but
Not true. Saving electricity is also a great source of energy.
-Sequence is the most important factor in energy strategy.
1. Energy conservation (reducing waste by being stingy, even down to using waste heat from sewage)
2. High efficiency
3. Renewable energy
I also talk about the same thing in my lectures, but at the stage where we don't reduce our energy consumption,
Japan's current approach of relying on facilities is by no means an essential one.
In 2009, Nagano spent 530 billion yen on energy-related projects such as oil and gas.
In the same year, the total sales of companies in Nagano Prefecture was 700 billion yen. Most of the expenditure was in oil-producing countries.
It is clear that money is not being distributed to the local areas.
If solar, wind and biomass power generation becomes widespread, it may be costly.
The installation work, maintenance, etc. will generate local jobs. This will reduce the amount of capital being invested overseas.
It also prevents leakage of fuel. What's more, it also promotes energy independence, which is excellent in terms of security.
-Related to the above, Japan is a country with few fossil fuel resources.
However, it is a country with sufficient renewable energy resources.
The country's forest resources are among the best in the world.
・As mentioned above, when money is distributed locally and jobs are brought to the local area, politicians
This will attract more votes for these policies, which will further accelerate their implementation.
Unfortunately, the example of Japan's lack of circularity in attracting expressways and other projects is a
It's on a different level.
・Heat accounts for 60% of the energy used. This is why we use waste heat from sewage.
We try not to waste any waste heat, even utilizing the heat generated during garbage disposal.
・It is said that there are about 40 million existing houses in Germany (57 million in Japan).
Of these, approximately 150,000 units (700,000 units) will be newly built.
Even the minimum standards for new buildings are stricter than Japan's top runner standards.
Among these, the highest Passive House standard is thought to be met in around 15% of new buildings.
Additionally, the company renovates 1% of existing homes each year to make them more energy efficient.
I don't think that these things will immediately lead to energy conservation, but there is a growing interest among businesses in energy conservation technology.
The accumulation continues. Currently, energy-saving renovations are 1% per year, but in the future, we would like to increase this to 2-3%.
If things continue as they are, all existing homes will be energy-efficient by 2050.
Not only will this enable enormous energy savings, but it will also create a living environment that is far more comfortable than in Japan.
- From 2006 to 2011, 6.8 billion euros were provided in subsidies for energy-saving renovations, etc.
The result was a 12-fold increase in employment, a very high investment efficiency.
- Wind power accounts for 7% of Germany's annual electricity production, while solar power accounts for 4%.
However, wind power generates 300 to 400 percent of demand during the windiest months of the year, January and February.
Even solar power can generate as much as 20% of its electricity in June.
So, we intentionally turn off the power generation during such times.
In order to make the most of this, the idea of power to gas is now being developed.
This is becoming more and more popular. It uses surplus electricity to electrolyze water, produce hydrogen gas, and
It seems that the idea is to mix CO2 to create artificial methane gas.
It will reduce our reliance on imported gas from Russia.
What do you all think?
Problems in Japan today include population decline, depopulation, and job insecurity for young people.
There are various problems, such as forest degradation due to the abandonment of forest resources.
The above method was devised to solve these problems simultaneously.
In terms of economic growth rate, Japan and the EU cannot compete with emerging countries in terms of population and wages.
I think we can say that we have entered a mature stage. Japan is either flying horizontally or descending.
Even though we know that we are in the EU, we are trying to move forward to a mature and ideal society like the EU.
They lack the vision to do so.
When we talk about this, we can say that Northern Europe and other countries have populations of about 5 million, which is about the same as Kyushu.
However, Germany has a population of nearly 100 million and an area similar to Japan.
Germany has a similar economy and is on par with the US.
What is lacking in Japan is the ability for everyone to discuss and talk about the ideal image and put it into practice.
I can't help but feel that there is.
