EROI Energy Return On Investment -- Are We Headed to Mad Max Days or Can Solar Dig Us Out

stock here: my specialties in my career are:

1) Energy of all sorts
2) Solar Photovoltaic and Thermal
3) Material Science and Manufacturing
4) Fractal Wave Pattern Analysis and Technical Prediction
5) Probability and Statistics

-----------------------------------------------------------------------------------------
So I read a very interesting article at Zerohedge, so interesting that I copied it and printed it.

http://www.zerohedge.com/news/2016-08-13/breakdown-us-global-markets-explained-what-most-analysts-miss#comment-7968548

Its a crazy world out there, some people think that high oil prices are a problem, some think that low oil prices are a problem. 

The jist of the "interesting article" is that the combination of 
1) Oil is getting harder to find and extract and
2) Lower oil prices
Will lead to a societal collapse and MadMax conditions in which you better own Gold.    

stock here-- so a quick summary, but I urge you to read the whole article.

The EROI is a ratio of the Energy you get out of a "product" compared to the energy you have to use to make the product.   So in the chart, he shows  Oil and Gas EROI (without backup information nor citing a source, but lets keep going)

 Then without justification or backup, he states that a EROI of 30 is necessary for an advanced society.   I don't really buy that, but I will give it some thought.   

Then he charts existing energy sources in a chart.   The takeaway is that he is showing Solar PV at less than 8.





--------------------------------------------------------------------------------------------------------------------
Then there are other sites that pretend to be fair and impartial, but are funded by the nuke cartel. 

The nuke cartel is particularly attacking solar, because solar it its death knell, cheaper, cleaner, no CO2.     

   notice this one jumping on the "climate meme"

https://bravenewclimate.com/2014/08/22/catch-22-of-energy-storage/#more-6460

They pretend that solar has a EROI of 1.6 to 3.9

NOW SOME FACTS -- The energy to create a solar panel is generated by the panel in about 8 months.    PV efficiency per size is up, production efficiency is also way up.

Panels last around 30 to 35 years, and almost all have 25 year warranties.

So it should be very clear cut that solar has a EROI over 30

So rather than choosing the "Mad Max" option, why don't we choose solar, and quickly?

    Hilary is a choice....

    1. If you choose not to decide you still have made a choice

    2. 5. Probability and Statistics

      Bayes was right.

      Nuclear will be with humanity as long as humanity wants a carbon free high power density energy source. The upside outweighs the downside.

    4. Lucey, you know i have thoroughly debunked the "power density" meme, it means nothing.

  2. What is carbon free about nuclear?... at least you could use the "low-carbon" semi-lie instead of the bold faced lie...
