Jan.15----Sustainable oil

The topic of this week is sustainable oil, and the speaker is a person who have a lot of experience in oil controlling.

There are four different parts of sustainable oil. They are exponential functions, peak oil, energy returned on energy invested, and Chris Martenson Crash course.




The speaker showed us several videos, and use them to introduce how people think about the oil issue, how they control those problems, and why oil become a serious sustainable problem in this decay.




The first video talked about three issues. The first issue is there are massive change upon us, and change a lot of living conditions. The second issue is overwhelming change is possible, because population growing more and more faster. The third issue is we are able to shape the future even though is may very hard.




The second video are very useful and interesting. It introduced exponential growth, and why there is exponential growth. I think that is very interesting because I already seen the population growing graph many times in my high school and university. However, I did not understand why there is an exponential growth, and how that happened. The larger basic population, the faster they growing.
Exponential growth means speeding up.

I found the video which is explain the meaning of exponential growth.

The third video is compounding ability.
It is very similar to the second video,and showed how a soccer auditorium were filled with people.

There is a finance rule of 72, 72/compound interest rat= number of years to double.
People focus on the demand and supply of oil recently, because oil is not only an important resource, but also it is reducing years after years.

Oil become to an controlling tool around the world. Therefore, people were trying to find a good way to let oil be more sustainable. People hope there will have enough oil can be used in the future.
We calculate a lot of data, and the result is use natural resource is better. Natural resources include wind, solar energy, and hydro.
From this lecture, I think I understand why people are evaluating other power. And I really think people should stop use coal. Also, let everyone understand why oil become to a reason of energy war.
