Kulamazwe, ukusetshenziswa okukhulu kwamandla avuselelekayo akuyona inhloso ezofinyelelwa, kepha kunalokho kuyimpumelelo okufanele igcinwe. Ukwenza okuhle kwe- imithombo yemvelo Amanye amazwe enze iphupho lokuba nomthombo wamandla avuselelekayo ayi-2017% lifezeke ngonyaka we-100.
Izifundazwe ezine zisebenza kahle kakhulu ku udaba lwamandla avuselelekayo, enikeza izifundo zamandla eminothweni emikhulu, okungukuthi, ukudala zonke izidingo zabo ngamandla "aluhlaza".
Uruguay
Elokuqala kulawa mazwe yi-Uruguay.NgoSepthemba 14, izwe laseNingizimu Melika lazuza cishe amahora angama-24 esizukulwaneni kusuka komoya, ugesi ophehlwa ngamanzi, i-biomass namandla elanga.
Amandla avuselelekayo
Uhulumeni waleli zwe uqokomisa ukuthi eminyakeni eyisithupha eyedlule i-Uruguay inayo kuhlanekezelwe ngaphezu kwamadola ayizigidi eziyizinkulungwane ezingama-22 kumandla avuselelekayo asimeme, ukunqoba ngale ndlela ukuncika kwawo ku-oyela negesi.
URamón Méndez, uMqondisi Kazwelonke Wezamandla nomgqugquzeli wohlelo lweminyaka engama-25, okuthi kusukela ngo-2008 lufuna ukuguqula Ukukhiqizwa kwamandla e-Uruguay, uthe "Sizoba nezikhathi eziningi lapho u-100% kagesi esiwusebenzisayo e-Uruguay uzobe uvela emoyeni".
Leli lizwe elincane labahlali abayizigidi ezingama-3,3 selivele lisebenzise amandla aphelele emifula yalo ukukhiqiza ugesi ophehlwa ugesi futhi selokhu lutshala imali minyaka yonke u-3% weGross Domestic Product (GDP) yalo ekuguqulweni kwesakhiwo ukufezekisa ukubusa kwamandla eminyakeni yesomiso futhi kunciphise ukugcwala kwayo kwezemvelo.
Ngokusho kukaMéndez, "Kuwo wonke amandla asetshenziswa yi-Uruguay, cishe u-50% usekelwe emandleni avuselelekayo, futhi emkhakheni kagesi ngo-2015 ngaphezulu kuka-90% kuzovela emandleni avuselelekayo."
Uma sibheka umbiko ovela kuWorld Wide Fund for Nature (WWF ngesiNgisi), Costa Rica, Uruguay, Brazil, Chile kanye neMexico bahola imizamo esifundeni shintsha umbandela futhi ukhethe amandla avuselelekayo esikhundleni sezinto zokubasa ezimbiwa phansi ezifana no-oyela namalahle.
Costa Rica
Ngenkathi iCosta Rica iqala ukukhuluma ngamandla ahlanzekile eminyakeni engaphezu kwengama-30 eyedlule, bekubonakala njengehlaya, kepha akuthathanga isikhathi eside ukuthi abanye bakopishe izinyathelo zayo. Kuze kube namuhla, izwe elaziwa njenge ICentral American Switzerland, isiqalile ukuvuna impumelelo enkulu ngaphezu kwezethembiso nezinhloso ezinhle.
ICosta Rica ithuthuka kancane kancane iba yizwe lokuqala laseLatin American elivuselelwa ngo-100%, isebenzisa imithombo ye-hydroelectric, geothermal, solar kanye ne-biomass.
i-World Wildlife Fund (WWF) ikhombisa kutsi lelive selisedvute nekufinyelela kulesisha ingqophamlando emlandweni wayo wamandla: ukuba izwe lokuqala eLatin America inikwa amandla yi-100% yamandla avuselelekayo.
Uma lo mbiko uhlaziywa, iWWF ikhombisa ukuthi iCosta Rica inamandla angama-gigawatts angama-223.000 ngonyaka kagesi ophehlwa ngamanzi, lapho ngaphansi kuka-10% kuyaxhashazwa, futhi inamandla amakhulu okukhiqiza i-geothermal nomoya. "Yipharadesi elikhulu kakhulu lamandla avuselelekayo esifundeni saseMelika Ephakathi."
Ngaphezu kwalokho, uhulumeni wazibekela umgomo wokuthola umnotho wekhabhoni ongathathi hlangothi, futhi ngalokhu wakhetha ukufinyelela ku-2021 ngokusetshenziswa kwamandla kusekelwe ngokuphelele emithonjeni evuselelekayo.
ILesotho
Ngo-1998 kwethulwa isitshalo sokuqala sokuphehla ugesi ezweni. Lokhu kukhiqiza u-90% wamandla owadingayo, amaSME akuleli asuselwa ekuguqulweni kwemikhiqizo yezolimo nokwenziwa kwezingubo. Lezi zinsuku zihlomule ngeziqu zakuleli ukuthola izinzuzo zoMthetho Wokukhula Nethuba lase-Afrika kuhulumeni wase-US. ILesotho ikwazile ukuvuselelwa ngo-100%, ngenxa yamandla kagesi ophehlwa ngamanzi, kepha kusenzima namanje ngesomiso ngalezo zikhathi ithenga amandla kwamanye amazwe angomakhelwane. Inqubo evuselelekayo kumele ihlanganiswe futhi isezinhlelweni zokuxazululwa.
Islandia
Amandla akulesi siqhingi esincane enyakatho yeYurophu asekelwe cishe ngokuphelele emandleni avuselelekayo. Ngo-2011 izwe lakhiqiza ama-65 GWh we amandla ayisisekelo, okungaphezulu kwama-85% avela emithonjeni yamandla avuselelekayo yendawo.
Amandla we-geothermal wezintaba-mlilo anikele ngezingxenye ezimbili kwezintathu zamandla ayisisekelo, ahambisana ne-hydroelectric 19,1% neminye imithombo. Ngo-2013, ugesi owakhiqizwa wafinyelela ku-18116 GWh, akhiqizwa empeleni Amandla avuselelekayo ayi-100% "adlule ama-99% ngo-1982 futhi abesecishe akhetheke kusukela lapho."
Ukusetshenziswa okuyinhloko kwe- amandla we-geothermal kungukushisa kwamabhilidi, ngo-45,4% wokusetshenziswa komhlaba okuphelele, nokukhiqizwa kukagesi, ngama-38,8%.
Zibalelwa ku-85% izindlu kuleli ziyafudumala ngalo mandla avuselelekayo.
