We could achieve significant energy savings just by changing the distortions and systems...

I was reminded of this again after reading Murakami Atsushi's blog today.

Murakami's blog is extremely detailed and easy to understand, but it is not a quick read.
To simplify the content of this blog, "Japan's surplus electricity purchase system for solar power generation is
It's not good. We should have a system like Germany where all the electricity is purchased and people who use it during the day on sunny days make more money.
"We should."
Under the current Japanese system, only the surplus electricity generated in your home minus the amount you used is used.
It will be purchased at nearly double the unit price. In this situation, the key is to increase the amount of surplus electricity.
As a result, the key to saving on electricity bills is, naturally, how to avoid using electricity during the day.
On the contrary, the price of nighttime electricity is set so low that it would be better to increase the ratio of nighttime electricity usage.
This will result in greater savings on your electricity bill.
If this system continues and solar power generation expands to 10 or 20 times its current size, people who are opposed to solar power will
It is easy for what is commonly called an unstable state to occur. Of course. Even though the amount of electricity generated is increasing,
Because there will be no one to use it...
In Germany, on the other hand, people who increase their own consumption when electricity generation is at its highest are more likely to make a profit.
It seems that the fee structure is based on this. If that's the case, everyone will shift their electricity usage to when there is a lot of electricity being generated.
There is a movement to try.
The smart house that relies on storage batteries was created to resolve this strange system contradiction.
At this point, I can only feel astonished.
It has such a huge social impact and how something so simple can be twisted in such a way.
There are many other examples like this. I always talk about this in my lectures.
In some cases, those who use all-electric appliances will have lower utility bills than those who reduce primary energy consumption.
This is one example of the twisted pricing system for electricity, gas, etc. in this country.
Also, not to be confused, but about 70% of the best-selling sashes in Japan today are
The U-value (thermal conductivity) is still around 4.65. If possible, the manufacturer
It would be better if they would voluntarily stop manufacturing these sashes, but only one company
If they stop selling and other companies are left with cheaper products, most home builders who only look at price based on economic principles will
The flow is to the cheapest remaining product. Windows are the building that loses the most heat, and once installed,
Once it is installed, it is often used as is for about 30 years.
It is unthinkable that this could be left alone in this day and age.
One effective way to stop this is the national minimum regulation system, which I have mentioned many times recently.
It may be difficult to suddenly lower the U-value of windows to 1.0 in Japan, but at least
Even if 3.49 or 2.91, which are becoming the standard among current housing manufacturers, were made mandatory,
I think it's good.
When it comes to energy conservation standards, various interests are involved, so it will not be easy, but in reality
In an industry that is dominated by two major companies, there is no reason to believe that setting minimum standards like this would be such a big hurdle.
I don't think there is. If so, why not do it? I find it hard to understand.
However, when it comes to geothermal power generation, relaxation measures have been put in place regarding drilling within national parks.
Perhaps it is the nature of this country to be sensitive to new things, but not interested in mundane things even if they are effective.
Maybe
