Kwezinye iindawo, akusekho ndawo yokuba iinkqubo ze-photovoltaic (PV) ziqhagamshelwe kwigridi. Kutheni ke ngoku sifakela ezinye ezininzi kangaka? Ngaba kukho imfuneko enkulu kangaka?
Abantu badla ngokugxeka i-PV kunye namandla omoya ngokuthi "ngumbane ongcolileyo," ofumanekayo xa ungafuneki kwaye ungafumaneki xa ufuneka, nto leyo ebangela impembelelo enkulu kwigridi. Eli shishini nalo likhuphisana kakhulu. Ingaba kusafanelekile ukusebenza kweli candelo?
Kukho ukungaqondani apha. NgokweNgqungquthela yoHlalutyo loPhuhliso lwaMandla aHlaziyiweyo ebibanjwe ngoFebruwari, izinga lokusetyenziswa kombane ovuthuzayo liyi-96.8%, kwaye elo lamandla e-PV liyi-98.3%. La mazinga okusetyenziswa aphezulu kakhulu, oko kuthetha ukuba phantse wonke umbane oveliswayo uyasetyenziswa, kwaye okwangoku, akukho ngxaki yokunciphisa amandla omoya okanye e-PV. Kwikota yokuqala ka-2024, amandla afakiweyo ombane ovuselelekayo adlule kwi-1.585 yeebhiliyoni zee-kilowatts, apho umoya kunye ne-PV zibiza i-1.1 yeebhiliyoni zee-kilowatts, ezenza i-52.9% yamandla afakiweyo. Ngo-2060, amandla afakiweyo omoya kunye ne-PV kulindeleke ukuba afikelele kwi-6 yeebhiliyoni zee-kilowatts. Ukuze sifezekise olu njongo, kufuneka songeze i-150 yezigidi zee-kilowatts zamandla afakiweyo minyaka le. Nangona kunjalo, ingxaki ebalulekileyo kukuba iindawo ezinemfuno ephezulu yombane zihlala zingenandawo yokufaka, ngelixa iindawo ezinesithuba zingenawo amandla okusebenzisa. Ngoko ke, kufuneka sakhe imigca emitsha ye-ultra-high voltage (UHV), iinethiwekhi zokusasaza, kunye neenkqubo zokugcina ixesha ezahlukeneyo.
Ngowama-2024, kulindeleke ukuba utyalo-mali lwehlabathi kwicandelo legridi yamandla lufikelele kwi-$400 yeebhiliyoni, apho imali engaphezulu kwe-$50 yeebhiliyoni ityalwe kubuchwepheshe bokugcina iibhetri, apho i-80% yayo iya kujoliswa kwilizwe lethu. Oku kubonisa impembelelo ebonakalayo yophuhliso lwamandla amatsha ekukhuleni koqoqosho.
NgokweNgxelo yoTyalo-mali lwaMandla eHlabathi yoNyaka ye-International Energy Agency, utyalo-mali lwamandla ehlabathi ngo-2024 luya kudlula i-$3 trillion okokuqala, apho i-$2 trillion iya kushishino lwamandla acocekileyo, kuquka amandla ahlaziyekayo, izithuthi zombane, amandla enyukliya, kunye nogcino. I-China yodwa kulindeleke ukuba ityale i-$675 billion, elingana notyalo-mali oludibeneyo lwe-US kunye ne-EU. I-China, i-US, kunye ne-EU kunye ziya kubala isibini kwisithathu sotyalo-mali lwamandla acocekileyo ehlabathi ngo-2024.
Ngokwembono yotshintsho lokhuseleko lwamandla kunye nokukhula koqoqosho okuqhutywa sisicwangciso se-dual-carbon, uphuhliso lwamandla amatsha ngokungathandabuzekiyo lubalulekile. Yiyo loo nto izicwangciso zesixeko zovavanyo lwe-carbon peak zigxininisa ukwenziwa ngcono kofakelo lwe-PV kwaye kutheni sibona amanyathelo afana neprojekthi ethi "100 Counties, 1000 Towns, and 10,000 Villages", equka amanyathelo anjenge-"Wind Action," "Sunshine Action," izithuthi ezintsha zamandla eziya kwiindawo zasemaphandleni, kunye nokugubungela izikhululo zokutshaja kwilali yonke.
