Ukususela ngo-2015, isabelo samandla elanga kunye nomoya kunikezelo lwamandla ehlabathi luphindwe kabini, ngokutsho kwetanki yokucinga u-Ember. Ngoku, ithatha malunga ne-10% yamandla ewonke awenziwayo, afikelela kwinqanaba lezixhobo zamandla enyukliya.
Eminye imithombo yamandla ithatha indawo yamalahle ngokuthe ngcembe, imveliso yawo yehle ngerekhodi le-2020% kwisiqingatha sokuqala sika-8,3 xa kuthelekiswa nexesha elifanayo ngo-2019. Umoya kunye namandla elanga babalelwa kuma-30% oko kwehla, ngokuka-Ember, ngelixa uninzi lokwehla kwaba ngenxa yobhubhani we-coronavirus wokunciphisa imfuno yombane.
Uphando luka-Ember lubandakanya amazwe angama-48, athatha i-83% yemveliso yombane yehlabathi. Ngokumalunga nomthamo wombane owenziwe ngumoya kunye nelanga, i-UK kunye ne-EU ngoku zikhokela. Okwangoku, le mithombo yamandla ingenye i-akhawunti ye-42% yokusetyenziswa kwamandla eJamani, i-33% e-UK kunye ne-21% kwi-EU.
Oku kuphezulu kakhulu xa kuthelekiswa nezona zingcolisi zekhabhoni ezintathu eziphambili: iTshayina, i-US kunye neIndiya. ETshayina naseIndiya, amandla omoya namandla elanga avelisa malunga neshumi lawo wonke umbane. Ngaphezu koko, iChina ithatha ngaphezu kwesiqingatha sawo onke amandla amalahle ehlabathini.
E-United States, malunga ne-12% yawo wonke umbane uvela kwiifama zelanga kunye nomoya. Ukuhlaziywa kuya kuba ngumthombo okhula ngokukhawuleza wokuvelisa umbane kulo nyaka, ngokutsho kwe-forecast ekhutshwe ekuqaleni kweveki yi-US Energy Information Administration. Ngo-Epreli ka-2019, inani lilonke lamandla enziwe e-United States ukusuka kwimithombo eluhlaza yadlula isabelo samalahle okokuqala, okwenza unyaka ophelileyo ube ngunyaka werekhodi kwimithombo yamandla avuselelekayo. Ngokutsho kweReuters, ekupheleni kuka-2020, isabelo semithombo yamandla avuselelekayo kunye namandla enyukliya kwisakhiwo seshishini lamandla ombane e-US kulindeleke ukuba ligqithise isabelo samalahle.
Konke oku kuyakhuthaza, kodwa kusekho indlela ende ekufuneka ihanjwe ukuhlangabezana nenjongo yesivumelwano semozulu saseParis sika-2015 sokuthintela umhlaba ekufudumaleni okungaphezulu kwe-1,5 degrees celcius ngaphezu kwamanqanaba angaphambi koshishino. Ukufezekisa le njongo, ukusetyenziswa kwamalahle kufuneka kuncitshiswe nge-13% ngonyaka kwiminyaka eyi-10 ezayo, kwaye ukukhutshwa kwe-carbon dioxide kufuneka kupheliswe phantse ngo-2050.
"Inyani yokuba imveliso yamalahle yehle nge-8% ngexesha lobhubhani wehlabathi ibonisa ukuba sisekude kangakanani ekufezekiseni injongo," utshilo uDave Jones, umhlalutyi ophezulu e-Ember. "Sinesisombululo, siyasebenza, kodwa ayenzeki ngokukhawuleza ngokwaneleyo."
