\"Bresil_1\"<\/a>Le Br\u00e9sil a atteint son ind\u00e9pendance \u00e9nerg\u00e9tique au niveau transport gr\u00e2ce d’une part \u00e0 une  production p\u00e9troli\u00e9re en plein essor, et d’autre part gr\u00e2ce aux biocarburants.
Sur une superficie de 8 500 000 km2, la population n’atteint que 188 000 000 d’habitant, ce qui est relativement modeste.
Le Br\u00e9sil produit environ 50 % des biocarburants consomm\u00e9s sur la plan\u00e8te, contre 40 % aux Usa et 10 % ailleurs.
Il existe 3 mani\u00e8re de produire du biocarburant :
– \u00e0 partir de l’huile (colza par exemple),
– \u00e0 partir du gaz obtenu par fermentation <\/a>(boues d’\u00e9purations),
– le bio\u00e9thanol<\/a> est obtenu \u00e0 partir de plantes ferment\u00e9es (canne \u00e0 sucre).<\/p>\n

Mais il n’\u00e9chappera \u00e0 personne que ce qui est possible au Br\u00e9sil<\/a>, avec une population modeste par rapport \u00e0 sa superficie, et avec un parc automobile modeste, avec des v\u00e9hicules mod\u00e9r\u00e9mment consommateur aussi n’est gu\u00e8re exportable.
Contre exemple, les Usa deuxi\u00e8me producteur, les biocarburants n’occupent qu’une part relativement modeste de la consommation.
L\u00e0, par contre, m\u00eame si on peut augmenter les surfaces cultiv\u00e9es destin\u00e9es \u00e0 la fabrication des biocarburants<\/a>, l’importance du parc, son peu de sobri\u00e9t\u00e9, ne permettront jamais l’autosuffisance, ni m\u00eame de prendre une part r\u00e9ellement significative de la consommation de carburants.
L\u00e0 aussi, seul le changement de standard, peut apporter un mieux.
Alors que les v\u00e9hicules europ\u00e9ens consomment en moyenne 6.5 litres au 100, les v\u00e9hicules nord-am\u00e9ricains en sont encore \u00e0 9.5 litres. Un gros effort reste \u00e0 faire. Mais en Europe aussi.<\/p>\n","protected":false},"excerpt":{"rendered":"
