Kusukela ngo-2015, isabelo samandla elanga nawomoya ekunikezeni amandla emhlabeni wonke siphindeke kabili, ngokusho kwe- think tank Ember. Njengamanje, ibalelwa ku-10% wawo wonke amandla akhiqizwayo, esondela ezingeni lezitshalo zamandla enyukliya.
Eminye imithombo yamandla kancane kancane ithatha indawo yamalahle, ukukhiqizwa kwayo kwehle ngerekhodi lama-2020% engxenyeni yokuqala ka-8,3 uma kuqhathaniswa nesikhathi esifanayo ngo-2019. Amandla omoya namandla elanga abalelwa ku-30% walokho kwehla, ngokusho kuka-Ember, kanti ukwehla okukhulu kungenxa yobhubhane lwe-coronavirus lokunciphisa isidingo sikagesi.
Ucwaningo luka-Ember luhlanganisa amazwe angama-48, enza ama-83% okukhiqizwa kukagesi emhlabeni jikelele. Ngokwenani likagesi okhiqizwa umoya nelanga, i-UK kanye ne-EU manje bayahola. Njengamanje, le mithombo yamandla ehlukile yenza ama-42% okusetshenziswa kwamandla eJalimane, ama-33% e-UK kanye nama-21% e-EU.
Lokhu kuphakeme kakhulu uma kuqhathaniswa nezingcolisi zekhabhoni ezintathu eziphambili emhlabeni: i-China, i-US ne-India. EShayina naseNdiya, amandla omoya namandla elanga akhiqiza cishe ingxenye yeshumi yawo wonke ugesi. Ngaphezu kwalokho, iChina yenza ngaphezu kwengxenye yawo wonke amandla amalahle emhlabeni.
E-United States, cishe u-12% wawo wonke ugesi uvela emapulazini elanga nawomoya. Izinto ezivuselelekayo zizoba umthombo okhula ngokushesha wokuphehlwa kukagesi kulo nyaka, ngokusho kwesibikezelo esikhishwe ngasekuqaleni kwaleli sonto yi-U.S. Energy Information Administration. Ngo-April 2019, inani eliphelele lamandla akhiqizwa e-United States avela emithonjeni eluhlaza ladlula amalahle okokuqala ngqa, okwenza unyaka odlule waba unyaka oyirekhodi wamandla avuselelekayo. Ngokusho kweReuters, ekupheleni kuka-2020, isabelo semithombo yamandla avuselelekayo namandla enuzi esakhiweni semboni yamandla kagesi yase-US kulindeleke ukuthi sidlule isabelo samalahle.
Konke lokhu kuyakhuthaza, kodwa luselude ukhalo okumele luhanjwe ukuze kuhlangatshezwane nomgomo wesivumelwano sesimo sezulu saseParis sangowezi-2015 sokuvimbela iplanethi ekufudumaleni okungaphezu kuka-1,5 degrees Celsius ngaphezu kwamazinga angaphambi kwezimboni. Ukufeza lo mgomo, ukusetshenziswa kwamalahle kufanele kwehliswe ngo-13% ngonyaka eminyakeni eyi-10 ezayo, futhi ukukhishwa kwe-carbon dioxide kufanele kuqedwe cishe ngo-2050.
"Iqiniso lokuthi ukukhiqizwa kwamalahle kwehle ngo-8% nje ngesikhathi sodlame lomhlaba wonke likhombisa ukuthi kusekude kangakanani ukufeza umgomo," kusho uDave Jones, umhlaziyi omkhulu kwa-Ember. "Sinesixazululo, siyasebenza, kodwa asenzeki ngokushesha ngokwanele."
