Ku North America ndi maiko ena otukuka, pali ntchito zambiri zomwe akufuna komanso kukulitsa mafuta.Kuonjezera apo, chifukwa anthu amasamalira kwambiri chitetezo cha chilengedwe ndipo boma lakhazikitsa malamulo otetezera chilengedwe, zoyeretsera zomwe zinakhazikitsidwa zaka zambiri zapitazo ziyenera kumangidwanso.Chifukwa chake, ndalama zomwe zayikidwa pakupanga mafuta ndi kuyengedwa zithandizira kukula muzaka zingapo zikubwerazi.Kumanga mapaipi amafuta ndi gasi aku China komanso kumanga mtsogolo kwa mapaipi akutali aku Russia kudzalimbikitsa kukula kwa msika wama valve pamakampani amafuta.Malinga ndi kukula kwanthawi yayitali kwa msika wamafuta ndi gasi komanso msika wotumizira ma valve, zikunenedweratu kuti kufunikira kwa mavavu pakukula kwamafuta ndi gasi ndikutumiza kudzakwera kuchokera ku US $ 8.2 biliyoni mu 2002 mpaka US $ 14 biliyoni mu 2005.
2. Makampani opanga mphamvu
Kwa nthawi yayitali, kufunikira kwa ma valve mumsika wamagetsi kwakhalabe kukula kolimba komanso kokhazikika.Mphamvu zonse zopangira magetsi otenthetsera ndi malo opangira mphamvu za nyukiliya zomwe zimamangidwa padziko lonse lapansi ndi 2679030mw, za United States ndi 743391mw, ndipo zantchito zatsopano zapamalo opangira magetsi m'maiko ena ndi 780000mw, zomwe zidzawonjezeka ndi 40% lotsatira. zaka zingapo.Europe, South America, Asia, makamaka msika wamagetsi waku China ukhala malo okulirapo pamsika wa valve.Kuchokera ku 2002 mpaka 2005, kufunikira kwa zinthu za valve pamsika wamagetsi kudzakwera kuchokera ku US $ 5.2 biliyoni kufika ku US $ 6.9 biliyoni, ndi kukula kwapachaka kwa 9.3%.
3. Makampani opanga mankhwala
Makampani opanga mankhwala amakhala oyamba m'makampani omwe ali ndi mtengo wopitilira 1.5 thililiyoni wa US dollars.Ndiwonso m'modzi mwa misika yomwe ikufunika kwambiri ma valve.Makampani opanga mankhwala amafunikira mapangidwe okhwima, mawonekedwe apamwamba kwambiri komanso zida zamakampani osowa.M'zaka zaposachedwapa, mpikisano pamsika wa mankhwala wakhala woopsa kwambiri, ndipo opanga mankhwala ambiri amayenera kuchepetsa ndalama.Komabe, kuyambira 2003 mpaka 2004, phindu lotulutsa ndi phindu lamakampani opanga mankhwala lawonjezeka kawiri, ndipo kufunikira kwa zinthu za valve kwabweretsa chiwongola dzanja chatsopano m'zaka 30 zapitazi.Monga tawonera mu chithunzi 4, pambuyo pa 2005, kufunikira kwa zinthu za valve mumakampani opanga mankhwala kudzawonjezeka pachaka ndi 5%.
