\section*{ConversionEnergieMondiale}

Énergie: 1 Exajoules = 1000 Petajoules = 1000000 Terajoules Puissance: 1 kW = 1000 Watts = 1000 Joules/seconde

la puissance est un débit d'énergie, ie un taux de consommation (ou de transfert) selon le temps. Par définition un Watt est un Joule déplacé (transformé, consommé) en une seconde. Souvent les quantités d'énergie indiquées sont annuelles (par an), il faut donc utiliser la correspondance 1 an = 365 * 24 * 3600 secondes

Mais rien n'est simple: j'ai découvert qu'il existe un bon écart (67\%) entre le TPES ( \emph{Total Primary energy supply} mentionné dans plusieurs rapports) et la \emph{Global primary energy consumption} \href{https://en.wikipedia.org/wiki/Primary_energy}{Wikipedia}

\begin{tabular}{l|l|l|l}
pays&Pop (Giga)&conso per capita (kw)&conso? globale\\
\hline 
2014 OCDE&pop&c2&6098 Mtoe\\
2014 non OCDE&c1&c2&8262\\
2014 tot&c1&c2&14360\\
\end{tabular}

\href{http://www.eia.gov/forecasts/aeo/data/browser/#/?id=1-IEO2016&region=0-0&cases=Reference&start=2010&end=2040&f=A&linechart=&ctype=linechart&sourcekey=0}{source: International Energy Outlook 2016 Table: World total primary energy consumption by region}

Bon, là il y a un problème car le 14360 Mtoe annuel ci-dessus pour 2014 diffère beaucoup trop du 8979 Mtoe de 2012 Final energy consumption sur \href{https://en.wikipedia.org/wiki/World_energy_consumption#Energy_supply.2C_consumption_and_electricity}{Wikipedia}\ldots{} Probablement que la \emph{International Energy Outlook 2016 Table: World total primary energy consumption by region} donne en fait le TPES et non pas comme ils le prétendent la consommation!


\vspace{.5em} \hrule \vspace{.5em}
Cherchons d'autre sources\ldots{}

[[ocde2014.jpg:pic]]

source: \href{https://www.iea.org/publications/freepublications/publication/KeyWorld_Statistics_2015.pdf}{2015 Key World Energy STATISTICS, IEA}

et pour le monde (Non OCDE) mais pour 2013 (pourtant dans le même document):

[[worldTPES.png:pic]]

Sachant que la ``\emph{Global primary energy consumption increased by just 0.9\% in 2014}'' \href{https://www.bp.com/content/dam/bp/pdf/energy-economics/statistical-review-2015/bp-statistical-review-of-world-energy-2015-full-report.pdf}{BP Statistical Review of World Energy June 2015} on peut obtenir que la TPES mondiale pour 2014 a été de 1.009 * 13541 Mtoe = 13664 Mtoe. Ce qui ferait:

\begin{tabular}{l|l|l|l}
pays&Pop&conso per capita (kw)&TPES globale\\
\hline 
2014 OCDE&pop&xyz&6098 Mtoe\\
2014 non OCDE&zzz&xyz&8425\\
2014 tot&xxx&zyx&13664\\
\end{tabular}

Ce qui semble confirmer que dans le tableau précédant ce ne sont pas des consommations mais des TPES\ldots{}

Je rappelle que la consommation est environ 67\% de la TPES car 33\% sont consommé par l'industrie energétique elle-même pour l'extraction et le raffinage\ldots{} un concept près de celui du EROI.

Mais tant qu'à ça, pourquoi ne considèrent-ils pas que par exemple dans un Internal Combustion Engine (ICE) seulement 1/3 de l'énergie est consommée mécaniquement, le 2/3 part en chaleur!!! Leur distinction entre TPES et FEC (pour Final Energy) consumption est imparfaite et trompeuse (sans vouloir l'être).

\hypertarget{et_les_watts}{}\paragraph*{{Et les Watts?}}\label{et_les_watts}

Pour la conversion des bilans énergétiques annuels en Watts continus, on obtient que 1000 Mtoe/yr = 1.328 TW = 1.328 milliards de kW.
