Amandla avuselelekayo anamandla amakhulu ngokwengeziwe ezimakethe nasekuncintisaneni. Zisebenza kahle kakhulu futhi zithuthuka ngokwengeziwe, okwenza ukuthi zifundwe ngokwengeziwe futhi zenze izinto ezintsha. Unyaka odlule ubhekwe njengonyaka wamandla avuselelekayo. Ngonyaka owodwa nje amandla aluhlaza afinyelela Ama-gigawatts ayi-153 (GW), ama-15% ngaphezulu kunango-2014.
Lokhu kusho ukuthi ngokokuqala ngqa emlandweni, amandla avuselelekayo afaka phakathi ngaphezu kwengxenye yokufakwa kwamandla ngonyaka, ukweqa izidingo nokusetshenziswa kwamalahle ngokwamandla anqwabelene afakiwe.
I-International Energy Agency (IEA) Uchaze ukuthi amandla avuselelekayo ahlangabezane nokushesha okuhle ezimakethe nasekuzithuthukiseni kwabo. Kodwa-ke, lokhu kwanda ekusetshenzisweni kwayo akukwanele ukufeza izinhloso ezinqunyiwe zokunqanda imiphumela yokuguquka kwesimo sezulu.
Enye yezimbangela ezenza ukuthi okuvuselelekayo kube namandla amakhulu emakethe ukuthi izindleko zokukhiqiza zibhekane nokwehla okuphawuleka kakhulu. Lokhu kungenxa yokwamukelwa kwezinqubomgomo eziqhubekayo kanye nentuthuko yezobuchwepheshe yokwandisa ezimakethe ezintsha ezinemithombo engcono evuselelekayo.
Umqondo lapho utshala imali kokuvuselelwa kabusha ukuthi kudinga umbono wesikhathi eside. Lokho wukuthi, izindleko zokuqala zokutshala imali zingabiza, kepha kuyakhokha ngokuhamba kwesikhathi futhi kunezinzuzo ezinhle. Kulinganiselwa ukuthi ngo-2021, amandla okuphehla ugesi emhlabeni wonke avela emandleni avuselelekayo izokhula ngo-42%. Lokhu kungumbono wethemba kakhulu kunalokho okwenziwe ngo-2015.
China uhlala njengoba umholi womhlaba ongenakuphikiswa ekwandiseni amandla avuselelekayo futhi ngokukhathalela ikhwalithi yomoya. E-European Union kuyachazwa ukuthi ukuqhubeka kokuvuseleleka kuncike ekukhuleni okuphansi kwesidingo samandla, ukuguqula umthetho osalindile emakethe nokucacisa ukungaqiniseki kwezepolitiki kwezinye izimakethe.
