Sekuyisikhathi eside isintu sisidla umhlaba wonke, sithatha inkulungwane futhi sithatha emanzini ngangokunokwenzeka, singayinaki ingozi eyenza yona. Izikhathi ziyashintsha kangcono, futhi namuhla inkinga yokuphepha kwemvelo yamabhizinisi nemikhiqizo iqala ukudlala indima ebalulekile. Abaningi bethu balungele ukunikeza okuningi ukuhlanza ukuphila kwethu ngomqondo wezemvelo: bathenga abahlanzekile bomoya namanzi, badle ukudla okukhulile ezindaweni ezihlanzekile, bancishise inani lempahla yasendlini baze baguqule indawo yabo yokuhlala. Yingakho kulesi sihloko sizokhuluma ngokuthi yiliphi izwe elingathiwa ngumngane wemvelo emhlabeni jikelele.
Ukulinganisa kwezinto eziphilayo zamazwe omhlaba
Ukuze kuhlolwe ngokulinganisela izinga lokuhlanzeka kwemvelo kunoma yimuphi umbuso, amanyuvesi ehamba phambili emhlabeni (Columbia naseYale) asethuthukile indlela ekhethekile ehlanganisa izilinganiso ezingaphezu kuka-25. Ngemuva kokucwaninga izizwe zomhlaba ngale ndlela, ososayensi banqume ukulinganisa kwamazwe anobungane kakhulu emhlabeni.
- Isikhundla sokuqala esinamaphesenti angama-95.5 angama-100 ngokuqinisekile sithathwe yiSwitzerland . YiSwitzerland okufanele ikhethwe njengendawo yokuhlala kuyo yonke labo abafuna ukuphila impilo ehlanzekile futhi ngesikhathi esifanayo ekhoneni lezomnotho emhlabeni. Kanye nephesenti eliphezulu le-GDP per capita, iSwitzerland ibonakaliswa izinkomba ezinhle kakhulu zomoya ohlanzekile namanzi, inamba enkulu yezindawo ezivikelwe. Ngokusho kwemithombo esemthethweni, yiSwitzerland ehambisana nokushintsha kwesimo sezulu esibucayi kakhulu esivela ngenxa yokuqubuka kwama-glaciers. Inkinga yokulondoloza imvelo lapha akukhathazi kuphela ngohulumeni, kodwa kuzo zonke izakhamuzi zendawo. Isibonelo, iziphethu ezishisayo zisetshenziselwa njengomthombo wokushisa ukushisa amakhaya, futhi amahhotela amaningi ahlinzeka izaphulelo zezivakashi zabo esebenzisa ukuthuthwa kwe-hybrid. Ngakho-ke isihloko sezwe elihlanzekile emhlabeni wonke lingelaseSwitzerland.
- Esikhundleni sesibili esimweni samazwe anobungane kakhulu emhlabeni, iNorway itholakala, engakwazi ukuziqhenya ngezimo zemvelo ezinhle kakhulu ezinike izakhamuzi ithuba lokujabulela indawo enhle futhi ziphefumule umoya omusha. Kodwa hhayi kuphela izipho zemvelo ezivumela iNorway ukuba ithathe indawo yesibili esilinganisweni. Ukufaneleka okukhulu kulokhu kanye nohulumeni wasekhaya, eminyakeni eyikhulu edlule eyadlulisela umthetho wokuvikelwa kwemvelo. Ngenxa yalomthetho kanye nokusungulwa okusebenzayo kwezithuthi ezithinta imvelo, ukukhishwa okulimazayo emkhathini eNorway kuyehle ngo-40%.
- Izindawo ezintathu eziphezulu ngokuphathelene nokuhlanzeka kwezemvelo yiSweden , cishe ingxenye yayo ehlanganiswa amahlathi. Uhulumeni waseSweden uyayinakekela imvelo, efuna ukunciphisa umthelela owingozi wokukhiqiza kanye nomboni wamapayipi kuwo okungenani. Ngakho-ke, emaqenjini aseSweden iminyaka eyishumi ezayo ukudluliselwa kwendawo yonke yokuhlala yokushisa ukushisa kwamafutha kuboniswa. Lokhu kusho ukuthi zonke izindlu zizoshiswa ngokusebenzisa imithombo yamandla enemvelo, njenge-energy elangeni, amanzi noma umoya.
Lawa mazwe amathathu aphezulu ekulinganisweni kokuhlanzeka kwezemvelo. Ngeshwa, i-Ukraine neRussia ayikwazi ukuziqhayisa
