Las amandla ahlaziyekayo (ekwabizwa ngokuba licocekile) ngawo onke loo mandla azibangeli iigesi zegreenhouse okanye nayiphi na into ephuma emngciphekweni. Amandla ahlaziyiweyo yi-hydroelectric, i-solar, umoya, i-tidal, i-geothermal okanye leyo evelisa i-biomass. Ukuveliswa kwezinye zazo kuxhomekeke kwiimeko zemozulu, kodwa ngokubanzi zifumaneka ngobuninzi obungenamkhawulo kwindalo.
Nangona olu hlobo lwamandla luhlala lunomatshini wokushicilela olungileyo, ukusetyenziswa kwawo kunako iingeniso kunye nokungalunganga. Yintoni ubungqina kwaye ayixhasi ingxoxo kukuba kungekudala okanye kamva Siya kunyanzeleka ukuba sizisebenzise kuba iyakuba kuphela kwendlela enokubakho nesebenzayo xa sisebenzisa ipetroli efana namalahle okanye ioyile.
Izibonelelo zayo zicacile. Masibone:
- Azingcolisi.
- Azipheli.
- Abadingi zicwangciso zokujonga inkunkuma abayenzileyo, umzekelo amandla enyukliya.
- Bavelisa ukuzimela ngakumbi kokubini kwiindawo zorhwebo kunye neendawo zokuhlala, kuba, umzekelo, imfuno yamandla inokugutyungelwa ngamandla elanga.
- Bavelisa imisebenzi kwaye inike imimandla emitsha yophando kunye nokuyila.
- Azibonisi naluphi na uhlobo lwesoyikiso kwimpilo yabantu, kwaye azichaphazeli kakubi izilwanyana kunye nezilwanyana.
Nangona kunjalo, banokunqongophala, nangona kungenakuphantse kube kungokuphinda kuhlaziywe. Nazi ezinye zazo:
- El iindleko eziphezulu zotyalo-mali. Zinexabiso eliphezulu lokuqala kwaye zihlala zingenanzuzo kude kube semva kwexesha, ukuze zibeke umngcipheko wotyalo-mali.
- Inokwenzeka rhoqo (kuxhomekeke kwimeko yemozulu), oko kuthetha ukuba ukubakho kwayo akunakuhlala kuqinisekisiwe.
- Zifuna iindawo ezinkulu ezifanelekileyo. Ke, umzekelo, ukuba ufuna ukuvelisa isixa esikhulu samandla ombane ngeepaneli zelanga, uzakufuna indawo enkulu yomhlaba oza kubeka kuyo iipaneli ezivelisa amandla aluhlaza.
- Nokanye unobume obahlukileyoOko kukuthi, ayizizo zonke iintlobo zamandla ahlaziyekayo anokusetyenziswa naphina, ngaphandle kwamandla afumana amandla ombane, ahluka ngakumbi. Nangona kunjalo, ifuna iindawo apho umaleko womhlaba unciphile khona ukuze ukuveliswa kwawo kusebenze ngokukuko.
- Amanye amandla aluhlaza avelisa impembelelo yomhlaba. Amandla omoya, umzekelo, anefuthe kubume belizwe kuba ifuna ukufakelwa koomatshini bomoya abakhulu, abaxhasi bazo banokubangela iingxaki kwezinye iintaka.
Yiyo loo nto, kucacile ukuba izibonelelo ezinikezelwa ngamandla ahlaziyekileyo zikhulu kunezinto eziphazamisayo abanokuzivelisa. Ukuphuculwa kokusebenza kakuhle kunye nenzuzo yala mandla manye isekwe kuphononongo, kuphando nakuphuhliso lweetekhnoloji ezintsha ezincedisa ezikhoyo ngoku nokuziphucula, ukuze kuveliswe iziphumo ezingcono izibonelelo zoqoqosho.
kubonakala kulungile
