Psychologie, mathématiques et choses connexes: L'anti-sexisme au service de l'anti-science

Le Plus du Nouvel Observateur nous gratifia le 27 octobre 2012 d'un texte de Nathalie Blu-Perou intitulé Les hommes infidèles à cause de leurs testicules ? La science au service du sexisme. Son billet montre le triste tableau de l'idéologie étouffant la raison. Dans la suite, je n'évoque que ce qui est écrit dans la première partie du document, à propos du lien entre... vous verrez plus bas.

These Are The Countries With The Greenest Economies

These Are The Countries With The Greenest Economies | Dr. Goulu | Scoop.it
As usual, Scandinavia tops the competition.
When it comes to the "green" economy in the U.S., perception outruns reality. We may not be doing as well are we think we are.

Goulu's insight:

Switzerland’s first year being covered on the GGEI reveals several opportunities for improvement. Overall, perceptions and performance are about equal in the top 10 for both, but a closer look at the four dimensions of the GGEI reveal growth opportunities. The general theme is that experts polled through our survey simply don’t give Switzerland quite the recognition it deserves. On both the Efficiency Sectors and Markets & Investment dimensions, Switzerland’s performance exceeds perceptions of it. Further efforts by Swiss leadership to embed green market opportunities in their sophisticated global communications platforms should improve this perception ranking for the future.

Un exemple de réseau électrique 100% renouvelable secouru par des batteries

Un exemple de réseau électrique 100% renouvelable secouru par des batteries | Dr. Goulu | Scoop.it
    Les ressources de puissance électrique renouvelable, telles que l’éolien ou le solaire   présentent une faiblesse opérationnelle   majeure: leur caractère intermittent, sinon aléatoire.
Goulu's insight:

Il me semble qu’un critère permettant de déterminer la capacité d’un tel système de stockage est la probabilité de se retrouver « à plat ». Sans stockage, le réseau sera mort chaque nuit sans vent. Avec un stockage correspondant à la consommation lors d’une telle nuit, le réseau sera mort la seconde de deux nuits sans vent consécutives, et ainsi de suite.

La question devient : combien de consommations nocturnes faut-il stocker pour réduire à x% la probabilité de black-out ? Sur une petite île, peut-être que x=1% est acceptable (ça fait quand même 4 nuits par an sans jus), mais nous nous sommes habitués à 0.1% ou même moins …

Si vous avez des références d’études permattant de déterminer la taille du stockage en fonction du risque de black-out, ça m’intéresse… Merci !
