Eminyakeni yakamuva,amandla elangaithole ukunakwa okusabalele njengomunye wemithombo yamandla avuselelekayo ethembisa kakhulu.Ngokukhula kokukhathazeka mayelana nokuguquguquka kwesimo sezulu kanye nesidingo sezinye izindlela ezisimeme zokusebenzisa uphethiloli,amandla elangakuvele njengento engase iguqule umdlalo.Kodwa angakanani amandla elanga okudingeka siwasebenzise ngempela, futhi ingabe angaba umthombo wamandla ovelele wesikhathi esizayo?
Ilanga liwumthombo wamandla amaningi, ngokuqhubekayo likhipha ama-terawatts angu-173,000amandla elangaemhlabeni.Eqinisweni, ihora elilodwa lokukhanya kwelanga lanele ukunika amandla umhlaba wonke unyaka wonke.Kodwa-ke, kunezinselelo ezimbalwa ekusebenziseni ngempumelelo la mandla kanye nokuwaguqula abe ugesi osebenzisekayo.
Okwamanje,amandla elangayenza ingxenye encane kuphela yokukhiqizwa kwamandla emhlabeni.Ngokusho kwe-International Energy Agency, amandla elangakubalwe kuphela u-2.7% wokuphehlwa kukagesi emhlabeni wonke ngo-2019. Lo mehluko udalwe kakhulu yizindleko eziphezulu zamaphaneli elanga kanye nokuphuma kokukhanya kwelanga.Ukusebenza kahle kwama-solar nakho kunendima ebalulekile ekunqumeni ukuthi amandla elanga asetshenziswa kanjani.Naphezu kwentuthuko yakamuva yezobuchwepheshe, ukusebenza okujwayelekile kwamapaneli elanga kuhlala kuzungeze i-15-20%.
Kodwa-ke, ngokuthuthuka okusheshayo kobuchwepheshe belanga kanye namanani ahlayo,amandla elanga kancane kancane iba inketho esebenzayo.Izindleko zamaphaneli elanga zehle kakhulu kule minyaka eyishumi edlule, okwenza atholakale emizini nasemabhizinisini engeziwe.Ngenxa yalokho, ukufakwa kwe-solar kuyaqhubeka nokwanda, ikakhulukazi emazweni anezinqubomgomo ezivuna uhulumeni kanye nezinzuzo.
Ngaphezu kwalokho, ukuthuthukiswa kwezinhlelo zokugcina amandla njengamabhethri kuxazulula inkinga yokukhanya kwelanga okuphakathi.Lawa masistimu angagcina amandla engeziwe akhiqizwa phakathi nosuku futhi awasebenzise ngezikhathi zokukhanya kwelanga okuphansi noma okungekho nhlobo.Ngakho-ke,amandla elangaingafakwa ngisho nalapho kungekho ukukhanya kwelanga, okuyenza ibe umthombo kagesi onokwethenjelwa futhi ozinzile.
Amandla weamandla elangaukuba umthombo wamandla ovelele wekusasa akungabazeki ukuthi kuyathembisa.Ngaphezu kokuba isisetshenziswa esivuselelekayo nesichichimayo,amandla elangainezinzuzo eziningi zemvelo.Ayikhiqizi igesi ebamba ukushisa ngesikhathi sokusebenza, inciphisa kakhulu i-carbon footprint uma iqhathaniswa nezibaseli ezimbiwa phansi.Amandla elanga nawo anamandla okuthuthukisa ukufinyelela kumandla ezindaweni ezikude lapho amagridi endabuko engakwazi khona.
Amazwe amaningi abonile amandla okuamandla elangafuthi izibekele imigomo ephambili yokwandisa isabelo sayo ekuhlanganiseni kwamandla.Isibonelo, iJalimane ihlela ukukhiqiza i-65% kagesi wayo emithonjeni yamandla avuselelekayo, laphoamandla elangaidlala indima ebalulekile.Ngokufanayo, i-India ihlose ukukhiqiza i-40% yamandla ayo emithonjeni evuselelekayo ngo-2030, ngokugxila kumandla elanga.
Nakuba amandla elanga anezinzuzo zawo, inguquko egcwele ukuzeamandla elangaizodinga ukutshalwa kwezimali okukhulu kwengqalasizinda nocwaningo.Ukwakhiwa kwamaphaneli elanga asebenza kahle kakhulu nezinhlelo zokugcina amandla, kanye nentuthuko kubuchwepheshe begridi, kubalulekile.Ukwengeza, ohulumeni nabenzi bezinqubomgomo kumele baqhubeke nokusekela ukukhula kwelanga ngokusebenzisa izikhuthazo zezimali kanye nemithethonqubo.
Ekuphetheni,amandla elangainamandla amakhulu okuba umthombo wamandla oyinhloko esikhathini esizayo.Ngokwaneleamandla elangaetholakalayo kanye nentuthuko emandleni ezobuchwepheshe nezomnotho,amandla elangaisiba yinketho esebenzayo.Nokho, uguquko olunqala ludinga ukutshalwa kwezimali okusimeme nokusekelwa ukuze kunqotshwe izinselele ezikhona.Ukusebenza ndawonye,amandla elangaingahlahla indlela yekusasa elihlanzekile, elisimeme.
