I-International Energy Agency isanda kukhipha umbiko okhethekile othi ukuze kufezwe wonke amazwe'Ngokuhambisana nemigomo yesimo sezulu kanye nokuqinisekisa ukuphepha kwamandla, umhlaba kuzodingeka wengeze noma ufake esikhundleni amakhilomitha ayizigidi ezingu-80 zamagridi kagesi ngo-2040 (okulingana nenani eliphelele lawo wonke amagridi kagesi akhona emhlabeni). Yenza izinguquko ezibalulekile ezindleleni zokuqapha.
Umbiko, othi “Amagridi Kagesi kanye Noshintsho Oluphephile Lwamandla,” ubheka isimo samanje samagridi kagesi omhlaba okokuqala futhi ukhomba ukuthi amagridi kagesi abalulekile ekususeni igesi eliyingozi kanye nokuhlanganisa ngempumelelo amandla avuselelekayo. Umbiko uxwayisa ngokuthi naphezu kwesidingo esinamandla sikagesi, ukutshalwa kwezimali kumagridi kwehla emazweni asathuthuka nasathuthuka ngaphandle kweShayina eminyakeni yamuva nje; amagridi okwamanje “awakwazi ukuhambisana” nokuthunyelwa okusheshayo kwezimoto zelanga, zomoya, zikagesi kanye namaphampu okushisa.
Ngokuphathelene nemiphumela yokuhluleka kwesilinganiso sokutshalwa kwezimali kwegridi kanye nesivinini esisheshayo sokuguqulwa komthetho wegridi, umbiko uveze ukuthi uma kwenzeka ukubambezeleka kwegridi, umkhakha wamandla'Ukukhishwa kwe-carbon dioxide okuhlanganisiwe kusukela ngo-2030 kuya ku-2050 kuzoba ngaphezu kwamathani ayizigidigidi ezingama-58 kunokukhishwa kwe-carbon dioxide okuthembisiwe. Lokhu kulingana nokukhishwa kwe-carbon dioxide okuphelele okuvela embonini yamandla omhlaba eminyakeni emine edlule, futhi kunethuba elingama-40% lokuthi amazinga okushisa omhlaba azokhuphuka ngama-degree Celsius angaphezu kwama-2.
Nakuba ukutshalwa kwezimali emandleni avuselelekayo bekulokhu kukhula ngokushesha, cishe kabili kusukela ngo-2010, ukutshalwa kwezimali kwegridi yomhlaba wonke akukanciphi, kusasele cishe ku-$300 billion ngonyaka, kusho umbiko. Ngo-2030, lolu xhaso kumele luphindwe kabili lube ngaphezu kuka-$600 billion ngonyaka ukuze kufezwe imigomo yesimo sezulu.
Umbiko uveza ukuthi eminyakeni eyishumi ezayo, ukuze kufezwe imigomo yamandla nesimo sezulu yamazwe ahlukahlukene, ukusetshenziswa kukagesi emhlabeni wonke kudingeka kukhule ngo-20% ngokushesha kunangeminyaka eyishumi edlule. Okungenani ama-gigawatts angu-3,000 amaphrojekthi wamandla avuselelekayo okwamanje alindile ukuxhunywa kugridi, okulingana nokuphindwe kahlanu kwenani lamandla amasha elanga kanye namandla omoya angeziwe ngo-2022. Lokhu kukhombisa ukuthi igridi iba yisithiyo ekuguqukeleni ekukhiqizweni okungenayo igesi.
I-International Energy Agency ixwayisa ngokuthi ngaphandle kokunakwa okwengeziwe kwenqubomgomo kanye nokutshalwa kwezimali, ukumbozwa okunganele kanye nekhwalithi yengqalasizinda yegridi kungenza imigomo yesimo sezulu yomhlaba ingafinyeleleki futhi kuphazamise ukuphepha kwamandla.
