agriculture from an energy point of view


Petros Chatzimpiros presents "Can agriculture be self-sufficient in energy?" during the Shift Workshops organized on September 24, 2019.
Pétros Chatzimpiros is a researcher at the Interdisciplinary Laboratory for Tomorrow's Energies (LIED) and a lecturer at the University of Paris-Diderot.

Basically it explains in figures what everyone interested in the sector already sensed.

a) Could the correct question have been auto AGAIN ...

Since it has been for 10 years ...

b) Doesn't we already have an excellent practical answer here with the work of Didier and his vegetable garden of the Lazy?

there I think you are making a mistake, the hay used by Didier is produced outside his vegetable garden and does not enter into his results, if you take this input of hay into account, its profitability drops dramatically ...

therefore always take the whole well and not just the part that supports the speech

Of course, but what is preventing Didier from growing his own hay?

Excellent, that's obvious ...

And as the covid has shown that all economic activity can almost stop except the food supply, it's not complicated, to save the planet, let's stop ANYTHING that is not strictly necessary.

Among other things, let's be lazy, let's stop working: “Make love don't go to work"

Right, I think over 60% of jobs in developed countries are not essential ...

This idea will make hay

Of course, but what is preventing Didier from growing his own hay?

...his heart!
More seriously, hay does not require too much effort because it is machines that take care of the essential. For my part, I produce hay (almost) manually and the bundling is painful (it is sometimes possible to skip this step if the source and the destination are close).
There are other ways of formulating this question, for example: with a population of 7 billion, is it possible to produce both the food and the energy that supposes it or not? In the past, with a much smaller demography, one of the best answers had been slavery ... Agricultural yield, including the energy absorbed, remains low and above all playable on a small scale ...
The industry is not doing much better, which we can now see that it is reaching an important stage of development *: what I find funny is that financial newspapers are starting to echo these concerns!

* Because negative externalities are not counted against the results.

@ Obamot: the covid did not demonstrate much, since the shutdown was only temporary and we could therefore benefit from the inertia, stocks and previous dynamics ...
“Make love not working”, but with a condom ...

@ Christophe, of course, they serve essentially to keep the system in operation, in other words this corresponds to a collapse of systemic efficiency (from - to - jobs produce abstract value and the latter is + and + redistributed to unproductive jobs according to this criterion; fortunately, the loans come to make up for this lack ...).

We always fall back on Jancovici's very correct reasoning of fossil virtual slaves ...

Since this subject is already rotten, I add a layer with this video which did not have the buzz it deserved!

Obviously people are so "work, work is life" ... hard to take the red pill ...
