Cinga ukuba amalahle ngamandla avela kwixesha elidlulileyo bubuxoki. Iminyaka yegolide yeli fosili yamandla yenzeka ngoku. Ngoba? Kumhlaba jikelele, ioyile isalawula, kodwa kumazwe e G20Nangona kunjalo, ngamalahle akhokelayo. Yile nto ityhilayo I-Enerdata Kwingxelo yakhe epapashwe ekupheleni kukaCanzibe.
Ngokwezibalo, ngo-2008, amalahle enza i-27% kunye petroleum 35% yamandla asetyenzisiweyo kumazwe ase G20 Kwiminyaka emihlanu kamva, ubudlelwane buye babuyiselwa umva amalahle inyukela kwi-34% kunye neoyile eyehla i-29%. Malunga ne gesi, isazinzile, iipesenti ezingama-20. Imeko engazinzanga, kuba amalahle ngamandla akhupha esona sixa sikhulu segesi yendlu eluhlaza.
Ngaphezulu kwe-60% yolonyuso kwi izinto ezikhutshwayo umhlaba ye-CO2 ukusukela ngo-2000 ivela kumlilo wamalahle ukuvelisa umbane Kunye nobushushu.
Nangona kunjalo, ayingawo onke amazwe kwi G20 babhenela kumalahle ngomlinganiselo ofanayo. Kwamanye amazwe Europe (ISpain, i-Itali, iBritani enkulu, iRomania), kukho utyekelo lokunciphisa iprofayile ye- amandla ehlaziyekayo. E-United States, imfuno yamalahle ifumana ukwanda, ngenxa yokunyuka kwamaxabiso amalahle. irhasi. Kodwa abathengi abakhulu kulapho icandelo lesinyithi likhula kakhulu kwaye apho kufunwa khona umbane ukwanda.
