Loyimvelo - ebalulekile ezweni lanamuhla

Umhlaba inezici esiyingqayizivele eyenza kube igugu bendawo yonke. Imvelo kanye nemithombo yemvelo ukuchaza isimo umnotho womhlaba. Ngakwelinye ihlangothi, ukuthuthukiswa kanye nokusetshenziswa uhlobo "izipho" imvelo kuncike ezidingweni zenhlalakahle kanye nezomnotho sabantu, kanye izici zemvelo esifundeni ngasinye. Izinto ezingokwemvelo emhlabeni wonke - umhlaba, amaminerali, amanzi, kanye nehlathi izinqolobane. Ngaphezu kwalokho, kulesi sigaba kungase kuhlanganise amasheya kwezilwandle: njengoba izimila nezilwane, namanzi, futhi izinto ngaphakathi.

Okwamanje, lezi zinhlobo ezilandelayo kwemithombo yemvelo: i ongashi kanye exhaustible. Lesi sakamuva, esikhundleni salokho, zihlukaniswe nalesebentisa non-ivuselelwe. Cabangela lezi zigaba kabanzi.

Exhaustible loyimvelo - ungumthombo wamandla ukuthi kungaholela esikhathini esifushane yesikhathi. Isibonelo bekuyoba amafutha namalahle, Peat, wezinto zokubasa. Lesi sigaba zingahlukaniswa ngamaqembu amabili. Eyokuqala zigcine engokwemvelo isimo sokungakhethi kwesikhwama evuselelekayo, okungukuthi, labo abamagama ukusetshenziswa kanye ukusetshenziswa lapho umuntu akakwazi bakha. Iqembu lesibili siqukethe kubakhiqizi abakhiqiza imithombo energy. Lokhu kuhlanganisa izinsiza elibuyisela umuntu njengoba kudingeka.

kufaka imithombo ongashi bemvelo iqembu ehlukile. Kuyinto umthombo wamandla ukuthi umuntu angasebenzisa cishe unomphela ngoba okuthiwa "izinqolobane enkulu" zalo. Ukuze lolu hlobo isikhundla njengoba amandla elanga, Aerospace, geothermal namandla emoyeni, kanye nabanye. Lamasu abizwa ngokuthi eminye imithombo kagesi, njengoba isintu ithemba ukuthi nge isikhathi bazokwazi ukufaka esikhundleni izinsiza exhaustible.

Ikhwalithi izinqolobane emhlabeni kanye nobungako kunemtselela isimo ezinkulukazi kwemvelo waphawula emhlabeni wonkana. izinkinga Global, njengokungcola inhlabathi, amanzi angcolile ocucuzayo, kongqimba lwe-ozone, imisebenzi yezomnotho engasimeme, kuncishiswe amathuba ukusetshenziswa imithombo yamandla.

Kuzo zonke imithombo yemvelo, kuncike umnotho zingahlukaniswa zibe:

1. Non-ukukhiqizwa. Leli qembu kuhlanganisa wonke esetshenziswa indoda, kodwa ayikwazi ukukhiqiza kubo. Ngokwesibonelo, amanzi, umdlalo izilwane noma flora zasendle ukuphuza.

2. Production. Lokhu kuhlanganisa zonke izinsiza ngoba zivunywa indawo kwakhiqiza noma indoda ekhule. Ngokufanayo ifa izinga ezolimo kanye izindlela (izitshalo ifolishi, ifolishi nezilwane kwezohwebo, inhlabathi, amanzi esetshenziswa ukunisela) kanye nemikhiqizo yezimboni (okusansimbi, Alloys, ukhuni, fuel).

Ngaphezu kwalokho, kukhona ngezigaba kwemithombo yemvelo ngenxa yosizo lwabo kwezomnotho. Hlukanisa emkhatsini amaminerali kanye nokubuka okungaphandle off-balance sheet. Lo mqeqeshi owake wapheka zihlanganisa esitokisini okwamanje iyasebenza. ukuthuthukiswa yabo nenzuzo kezomnotho kuwusizo ukwenza kanjalo. Okwesibili, ngokungafani, okudinga okunamathiselwe amathuluzi eyengeziwe, ngoba ezindaweni eziyinkimbinkimbi isizinda, edinga ukucutshungulwa izimo akhethekile abe Inani elincane imali.
