Amalahle aqala ukusetyenziswa ukufudumeza amakhaya aseMelika kunye neefektri ngeminyaka yoo-1880. Sele kudlule iminyaka engaphezu kwekhulu ukususela ngoko, kodwa nangoku kusetyenziswa amafutha exabiso eliphantsi kwizikhululo ezenzelwe ukuvelisa umbane. Kangangamashumi eminyaka, amaziko ombane wamalahle ayelawula eUnited States, kodwa ngokuthe ngcembe athatyathelwβ indawo yimithombo yamandla ahlaziyekayo, eye yanda ngokukhawuleza kwiminyaka yakutshanje.
Imithombo yenethiwekhi inika ingxelo yokuba ngo-Epreli ka-2019, imithombo yamandla evuselelekayo ikwazile ukugubungela izityalo zamalahle okokuqala e-United States. Imithombo yamandla ehlaziyekayo ivelise umbane ongaphezulu kwe-16% kunezityalo zamalahle ngo-Epreli, ngokutsho koLawulo lweeNkcukacha zaMandla. Imveliso yamandla ahlaziyekayo yelizwe kulindeleke ukuba ikhule nge-1,4% xa ithelekiswa namalahle ngoMeyi.
Ngenxa yokuba imithombo yamandla ehlaziyekayo isetyenziswa ngamaxesha athile onyaka, ekupheleni kuka-2019, izityalo zamalahle ziya kuphinda zivelise umbane omninzi. Ngaphandle koku, kukho ukukhula okuqinisekileyo kumandla ahlaziyekayo. Kulindeleke ukuba kunyaka ozayo umthamo wombane oveliswayo ulingane.
Abameli bombutho ongenzi nzuzo i-Institute for Energy Economics and Financial Analysis (IEEFA) bathi nangona ukungahoywa kweengxelo zenyanga kweli cala ngabaxhasi bamandla amalahle, zibalulekile kwaye zibonisa ngokucacileyo ukuba utshintsho olusisiseko sele lwenzeke kumbane. icandelo lokuvelisa. Baqaphela ukuba amandla avuselelekayo afumana izityalo zamalahle, edlula isantya sokukhula ebesiqikelelwe ngaphambili.
