The final session of the Berkeley Hot Class was also excellent.

The final episode of Professor Muller's exciting class was also excellent.
Although I'm a few days late, I watched the final episode of NHK's "Berkeley School of Letters."

As I was watching the program, I came across various documents that I had never seen before. I took pictures of the screen with my digital camera.
I would like to introduce a few points.
First of all, this document is extremely reliable, as it was created by the US Department of Energy.
This is high data.

The units are hard to read but are cents/kwh.
As of today, 1 dollar is 98 yen, so it is safe to say that 1 cent is roughly equal to 1 yen.
What I think is different from Japan is that, of course, the nuclear power plant prices are higher.
Gas has become cheaper than coal. This is due to the discovery of shale gas in the United States.
The drop in gas prices due to the nuclear power plant is a major factor.
(It does not include any costs incurred in the event of an accident.)
Next, wind power is about the same price as coal.
It doesn't emit CO2, which is why countries around the world are scrambling to expand wind power generation.
The unit price of solar power is about twice that of wind power, and as of 2011, it is still expensive.
I understand that. However, for some reason, only solar power has become popular in Japan, while wind power has hardly grown at all.
I think so.
The main reason for this seems to be the problem of securing space to build wind turbines.
In Japan, a maritime powerhouse, offshore wind power is seen as the favorite.
It is said to cost about twice as much as wind power, or roughly the same as solar power.
Nevertheless, countries such as the UK, China, Belgium and Denmark are very proactive in promoting offshore wind power as part of their national policies.
Some countries are already moving forward with this. In particular, the UK is aiming to cover one-third of its electricity needs by 3.
Apparently, he plans to go. The UK, which is an island nation with similar national power, population, and area, can do it, but Japan can't.
I don't think there is any reason. Also, if offshore wind power can be produced at the same cost as solar power, it would be a good idea to use natural energy.
If we are to smooth out the uneven power generation situation, the government should provide incentives to further promote offshore wind power.
I think I have to give it a go. I plan to write more about offshore wind power tomorrow, so today,
That's all for now.
Another interesting piece of data was the table below.

Blue represents each country's recoverable oil reserves. Looking at this, we can see that the United States and China have very little oil left.
I understand. Canada was in a similar situation until about 10 years ago, when the oil sands were discovered.
This resulted in a sudden increase in recoverable reserves.
Here's where it gets interesting. Of course there are recoverable reserves of gas, but the red part in the table shows that they have been converted into the equivalent energy value of oil. Looking at this, we can see that America, which has now produced shale gas, still has a large amount of fossil fuels within the country.
These things were announced by the US central government, and the most popular physics professor at a top US university
That's what I'm teaching.
In addition, it is certain that construction costs for nuclear power plants have increased since estimates due to the effects of the March 11 disaster.
On the other hand, the cost of natural energy has fallen dramatically, as can be seen from the massive drop in the price of solar power generation.
Even with these objective facts, people still say that "nuclear power is economical" and "natural energy is expensive."
I feel sick when I hear the current administration's sophistry. They are also partly or completely
You should know.
However, from the perspective of national defense, we cannot abandon nuclear weapons.
