Ukusetshenziswa kwamandla avuselelekayo ukufaka esikhundleni sezibaseli kuthathwa njengenye yezinto ezibalulekile ukulwa nokuguquka kwesimo sezulu nezinkinga zemvelo global sina.
Kepha isimo siyinkimbinkimbi kakhulu kusukela lapho amandla avuselelekayo ayingxenye yesixazululo kodwa ngasikhathi sinye zingathinteka ezinkingeni ezithile zemvelo ekusebenzeni kwazo, ekukhuliseni noma ekulahleni ngenxa yokonakaliswa kwemvelo.
Amandla avuselelekayo nezinkinga zemvelo
Uma ukuphazamiseka nokubhujiswa kwemvelo kwamanje kuqhubeka, kuzokwenzeka Imithombo yamandla ivuseleleke kungathinteka enanini lokukhiqizwa kwamandla.
Abathinteka kakhulu bazoba ugesi ophehlwa ngamanzi ngoba ukuguquka kwesimo sezulu kubanga ukwehla kwemifula lapho isetshenziselwa le nhloso ngaphezu kokungcola kwamanzi okuthikameza ukukhiqizwa ugesi.
Uma ingekho amahlathi noma izindawo zemvelo ayikwazi ukuqoqwa i-biomass ukukhiqiza amandla, kokubili kagesi kanye biogas ngakho-ke izitshalo ze-biomass zingathinteka ngokungabikho kwezinto zokusetshenziswa kwezinye izindawo.
La ukuncipha kwamapulazi ngenxa yokusebenzisa kwabo kabi nokucekelwa phansi kwempahla kungathikameza kakhulu ukukhiqizwa kwezitshalo eziqonde ama-biofuel ngoba bazoncintisana namasimu ambalwa okulinywa anamandla okulima ngokudla, okuyinto embi kakhulu.
Le mithombo yamandla iyavuseleleka kodwa imithombo yemvelo ayipheli.
Isixazululo sezinkinga zemvelo
Ukuphathwa okwanele kuyadingeka ukuze bakwazi ukukhiqiza amandla ngokungapheli, kepha uma kwehliswa noma kusetshenziswa ngokweqile, amandla ayo okwenza lokho ancipha noma alahleke ngqo.
Ngokuxazulula izinkinga zemvelo ezithinta iplanethi hhayi kuphela thuthukisa ikhwalithi yempilo ngaphandle kwalokho sizobe sivikela amandla okukhiqiza amandla.
Amandla avuselelekayo ayingxenye yesixazululo kodwa hhayi kuphela, kufanele kwenziwe izinyathelo ezahlukahlukene ukugwema ukuqhubeka nokonakalisa imvelo kanye nemithombo yemvelo. Kungale ndlela kuphela lapho kuzokwazi khona ukuqinisekisa ukuthi kungenzeka ukukhiqiza inani elikhulu le- amandla ahlanzekile ngokuya ngemithombo yamandla evuselelekayo yazo zonke izinhlobo zemisebenzi yesikhathi eside.
