1. Imboni kawoyela negesi
ENyakatho Melika nakwamanye amazwe athuthukile, maningi amaphrojekthi kawoyela ahlongozwayo nanwetshiwe.Ngaphezu kwalokho, ngenxa yokuthi abantu banaka kakhulu ukuvikelwa kwemvelo futhi nombuso ususungule imithethonqubo yokuvikela imvelo, izindawo zokuhluza ezasungulwa eminyakeni eminingi edlule kumele zakhiwe kabusha.Ngakho-ke, izimali ezitshalwe ekuthuthukisweni kukawoyela nokucwengisiswa zizogcina umfutho wokukhula eminyakeni embalwa ezayo.Ukwakhiwa kwepayipi laseShayina likawoyela negesi elihamba amabanga amade kanye nokwakhiwa kwesikhathi esizayo kwepayipi laseRussia elihamba amabanga amade kuzokhuthaza ngqo ukukhula kwemakethe yamavalvu embonini kawoyela.Ngokwentuthuko yesikhathi eside yokuthuthukiswa kukawoyela negesi kanye nemakethe yama-valve wokudlulisa, kubikezelwa ukuthi isidingo samavalvu ekuthuthukisweni kukawoyela negesi kanye nokudluliselwa kuzonyuka sisuka ku-US $8.2 billion ngo-2002 siye e-US $14 billion ngo-2005.
2. Imboni yamandla
Isikhathi eside, isidingo sama-valve embonini yamandla siye sagcina izinga lokukhula eliqinile nelizinzile.Isamba sokuphehlwa kwamandla eziteshi zamandla ashisayo kanye neziteshi zamandla enyukliya ezakhiwe emhlabeni wonke zingama-2679030mw, esase-United States singu-743391mw, kanye namaphrojekthi eziteshi zamandla amasha kwamanye amazwe angu-780000mw, azokhula ngo-40% ngokulandelayo. iminyaka embalwa.I-Europe, iNingizimu Melika, i-Asia, ikakhulukazi imakethe yamandla yaseChina izoba yindawo entsha yokukhula yemakethe yama-valve.Kusukela ngo-2002 kuya ku-2005, isidingo semikhiqizo ye-valve emakethe yamandla sizokhuphuka sisuka ku-US $ 5.2 billion siye ku-US $ 6.9 billion, ngokukhula okuphakathi konyaka okungu-9.3%.
3. Imboni yamakhemikhali
Imboni yamakhemikhali ikleliswe kuqala embonini ngenani eliphumayo elingaphezu kwe-1.5 trillion US dollar.Futhi ingesinye sezimakethe ezinesidingo esikhulu samavalvu.Imboni yamakhemikhali idinga ukuklama okuvuthiwe, izinga eliphezulu lokucubungula kanye nezinto ezingavamile zezimboni.Eminyakeni yamuva, ukuncintisana emakethe yamakhemikhali kuye kwashuba kakhulu, futhi abakhiqizi bamakhemikhali abaningi kufanele behlise izindleko.Kodwa-ke, kusukela ngo-2003 kuya ku-2004, inani lomkhiqizo kanye nenzuzo yemboni yamakhemikhali kuphindeke kabili, futhi isidingo semikhiqizo yama-valve siye saletha inani eliphakeme elisha eminyakeni engu-30 edlule.Njengoba kuboniswe emfanekisweni wesi-4, ngemva kuka-2005, isidingo semikhiqizo yama-valve embonini yamakhemikhali sizokhula ngezinga lokukhula lonyaka lika-5%.
