Umhlaba uya ngokuya usebenzisa futhi uthuthukise ubuchwepheshe emkhakheni wamandla avuselelekayo. Izinkampani eziningi nezimakethe zinikezelwe emisha nasekucwaningeni kulo mkhakha. Kepha ngezinga lokuthi sisancike kumafutha wezinto ezimbiwa phansi kanye nemithelela ebonakala kakhulu yokuguquka kwesimo sezulu, umkhakha ovuselelekayo kufanele ithuthuke ngokushesha okukhulu.
Izinsiza Zomhlaba Zomhlaba Zika-2016, okwethulwe izolo e-Istanbul, kuveza ukuthi ukukhula okuphezulu kwemakethe yamandla avuselelekayo eminyakeni eyi-15 edlule. Izici ezahlukahlukene zemakethe zenziwe ngcono, kusuka ekutshaleni okwandisiwe, amandla amaningi okukhiqiza amandla nokusebenza kahle kakhulu.
Isimo samandla omhlaba sibe nezinguquko ezinkulu kusukela ngonyaka ka 2000. Namuhla, amazwe amaningi ahlinzeka ngohlelo oluxubene lwamandla, phakathi kwamandla okubasa kanye namandla avuselelekayo. Kodwa-ke, lo mbiko ukhombisa ukuthi izinga lapho okuvuselelwa kabusha kukhula khona ngaphansi kokudingekile ukuhlangabezana nezinhloso zokukhishwa kwegesi engcolisa ukushisa.
Kunezinto eziningana okufanele zicatshangelwe kulolu shintsho kumandla wezwe womhlaba. Sithola izici ezifana nokwehla kwamanani kagesi, ukuhlukaniswa okukhulu phakathi kokukhula komnotho kanye nokukhishwa kwegesi ebamba ukushisa, ukuqhubeka kwezinto ezivuselelekayo emazweni asathuthuka, njll. Phambilini, ukukhula komnotho wezwe kwakulingana ngqo nokukhishwa kwamagesi akhishelwa emoyeni. Lokhu akudingeki ukuthi kube njalo namuhla ngenxa yokuvuselelwa.
UMongameli oPhethe we-World Resources Energy, UHans-Wilhelm Schiffer, uthe lo mbiko ukhombisa ukuthi ukwehlukaniswa kobuchwepheshe nezinsizakusebenza, okusetshenziswa emkhakheni wezamandla, kudala amathuba amaningi, kodwa futhi kube yinkimbinkimbi enkulu nokwanda kwezinselelo.
