Chapter 17b – Energy Budgeting (2 of 2): Petroleum has supplied the surplus energy that has allowed for social complexity, industrialization, and the modern conveniences that we enjoy. In this chapter, Dr. Chris Martenson explains that in the future our supply of surplus energy will decline due to the fact that increasing amounts of energy will be required to produce new energy. When poor net energy (ERoEI) returns are paired with peak oil production, it points to a return to a less complex society.

i love this series and i think this guy is brilliant. however, he is making an error in this video. there is a MASSIVE source of easily accessible of hydrogen on earth, WATER (H2O). he correctly points out that the hydrogen needs to be liberated to be used as fuel but incorrectly states that this will yield a net zero return on energy. the hydrogen can be separated from the oxygen with a simple electric current (supplied by a renewable like wind or hydroelectric).

OMG! Oil today has net energy ratio

Haha, if I had the …
Haha, if I had the living standard of 5:02, I would still be a king plus my dreams would come true. I live now way lower than that in a poorly noice insulated flat, which I hate very much. The truth is, that after peak oil many poorer people end up into the streets.

The thing on 4:30 is a bit of an irrelevent thing, you should have said more ‘common’ jobs, like people hwo make toys.
According to …
According to Wikipedia, which has several sources for the data, the net energy balance in Brazil for sugarcane ethanol is 8.3-10.2, versus 1.3 in the US for corn. I think with all of our technology and educated people, we can do better.
And what about Nuclear? I’ve seen it at 4 and higher. Nuclear is the way to go.

* Henry Ford’s first Model-T was built to run on hemp gasoline and the CAR ITSELF WAS CONTRUCTED FROM HEMP! On his large estate, Ford was photographed among his hemp fields. The car, ‘grown from the soil,’ had hemp plastic panels whose impact strength was 10 times stronger than steel; Popular Mechanics, 1941.
* 80% of all textiles, fabrics, clothes, linen, drapes, bed sheets, etc. were made from hemp until the 1820s with the introduction of the cotton gin.
A more accurate …
A more accurate measure would be the cost per barrel of the recovery of the oil. This is what the industry uses to measure if they can still make a profit off of it. Tar sands cost $15/barrel to recover. Conventional oil in Saudi Arabi only costs about $5/barrel to recover. Shale oil in Colorado is $16/barrel. As long as oil is above $60/barrel there will be a usable market for shale and tar sand. There’s still plenty of conventional oil, though.
PEAK OIL has been …
PEAK OIL has been reached. Time to dump OIL as an energy source, before we ruin our biosphere any more. Time to stop blocking ans start deploying ALTERNATIVE ENERGY.
great great …
great great material!!! i really appreciate the effort you put into this.
by the way, do you know where does geothermal energy lie on the net energy graph? biofuel was obviously dubious from the very start as it raised numerous problems even without the net energy ones…
i’m curious about tidal, wave and primarily geothermal.
would appreciate any further information or reference!
i don't? think i will make one about 99 smithing as it's pretty simple to train and not many people have problems with it
