Crash Course: Chapter 17b - Energy Budgeting (2 of 2) by Chris Martenson

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.

thank you 4 teaching me... please, dont thank me 4 wanting to better the planet

[bayleybomber]

bighorn there is free energy all around us , mayflower did'nt have a oildissel engen did it? . Granted such a vessle does a bltsing 5 miles p hr

@bighorn2004 it take more energy to break those hydrogen bonds between oxygen and hydrogen, therefore extracting hydrogen is not energy efficient. Look it up in a science book.

and makes them move around creating wind, sun is consuming hydrogen, the palnt also consume hydrogen to have energy to produce carbohydrates, it is estimated that solar/hydrogen energy has the potential to sustain four hundred times the current world population ...

[Pedro60037]

the Part of the hydrogen is not very logical, because most of all energy consumed by humanity is directly or indirectly hydrogen energy, fossil fuels such as coal and crude oil is not more than photosynthetic energy stored as fossil, the driving force that is behind the wind comes from the solar radiation that heats air masses,

@MacabreManifesto ...exponentially, and that it takes the soil 23 times longer to regenerate the required nutrients to grow corn the way we do so, in the end, we could only use 1/23rd of our land every year to grow fuel, but then there would be nothing left for food. In the end, ethanol is great for the oil companies but accelerates our downfall.

[MacabreManifesto]

What I have heard about Ethanol is that it takes 2.3 calories of oil and natural gas, to make 1 calorie of Ethanol. These calories come both from the energy we use go get it out of the ground and into the average tank, and also the physical crude oil and natural gas products that would have been used to create things like pesticides that make our intensive farming today posible. Speaking of intensive farming, if we switched to farming we have to consider that our soil is eroding, well...

[siprus]

you should have said that hydrogen can be used to make wind and solar energy power cars and other oil based things -_-

@bighorn2004

The energy you get from burning hydrogen is the same you need to get hydrogen from water.

You gain no energy, you just convert it from one form to another.

@breeannaqktjbl spam elsewhere. there is no free energy.
