Cabanga ukuthi amalahle Kungamandla avela esikhathini esedlule. Amanga. Iminyaka yobudala yegolide yalezi zinsalela zenzeka njengamanje. Kungani? Emhlabeni jikelele, uwoyela usabusa, kepha emazweni we G20Kodwa-ke, ngamalahle aholayo. Lokhu kuveza lokhu I-Enerdata embikweni wakhe owashicilelwa ekupheleni kukaMeyi.
Ngokwezibalo, ngo-2008, amalahle abengu-27% kanti i-petroleum 35% wamandla asetshenzisiwe emazweni we G20. Ngemuva kweminyaka emihlanu, ubudlelwano buguqulwe nge amalahle lokho kukhuphukela ku-34% kuthi uwoyela uwe ku-29%. Mayelana ne Igesi, isazinzile, 20%. Isimo esingenakusimama, ngoba amalahle angamandla akhipha inani elikhulu kakhulu lamagesi abamba ukushisa.
Ngaphezu kuka-60% wokukhushulwa kwe- ukungcola umhlaba we-CO2 kusukela ngo-2000 uvela emlilweni wamalahle wokukhiqiza ugesi Nokushisa.
Kodwa-ke, akuwona wonke amazwe ku- G20 basebenzisa amalahle ngezilinganiso ezifanayo. Kwamanye amazwe e Europa (ISpain, i-Italy, iGreat Britain, iRomania), kukhona nokuthambekela okwehlisa iphrofayili ye- amandla ivuseleleke. E-United States, ukufunwa kwamalahle kubhekene nokwanda ngenxa yokwenyuka kwamanani entengo ye- Igesi. Kepha abathengi abakhulu kulapho umkhakha wensimbi ukhula kakhulu nalapho isidingo sakhona ugesi ukwanda.
