Amalahle aqala ukusetshenziselwa ukushisisa amakhaya namafekthri aseMelika ngawo-1880s. Sekudlule iminyaka engaphezu kwekhulu kusukela ngaleso sikhathi, kodwa ngisho namanje uphethiloli oshibhile usetshenziswa kakhulu eziteshini eziklanyelwe ukuphehla ugesi. Sekungamashumi eminyaka, izitshalo zikagesi wamalahle zibusa e-United States, kodwa kancane kancane zithathelwa indawo imithombo yamandla avuselelekayo, ebilokhu ikhula ngokushesha eminyakeni yamuva.
Imithombo yenethiwekhi ibika ukuthi ngo-Ephreli 2019, imithombo yamandla avuselelekayo ikwazile ukusibekela izitshalo zamalahle okokuqala ngqa e-United States. Imithombo yamandla avuselelekayo ikhiqize ugesi ongu-16% ngaphezu kwezitshalo zamalahle ngo-Ephreli, ngokusho kwe-Energy Information Administration. Ukukhiqizwa kwamandla kagesi avuselelekayo kuleli kulindeleke ukuthi kukhule ngomunye u-1,4% uma kuqhathaniswa namalahle ngoMeyi.
Ngenxa yokuthi imithombo yamandla avuselelekayo isetshenziswa ngezikhathi ezithile zonyaka, ekupheleni kuka-2019, izitshalo zamalahle zizophinde zikhiqize ugesi owengeziwe. Ngaphandle kwalokhu, kukhona ukuthambekela kokukhula okuqinisekile kwamandla avuselelekayo. Kulindeleke ukuthi ngonyaka ozayo umthamo kagesi okhiqizwayo ucishe ulingane.
Abamele inhlangano engenzi nzuzo i-Institute for Energy Economics and Financial Analysis (IEEFA) bathi naphezu kokushaywa indiva kwemibiko yanyanga zonke ngale ndlela ngabasekeli bamandla wamalahle, babalulekile futhi bakhombisa ngokusobala ukuthi sekuvele ushintsho oluyisisekelo kugesi. umkhakha wokukhiqiza. Baqaphela ukuthi amandla avuselelekayo ahambisana nezitshalo zamalahle, adlula izinga lokukhula elaliqanjiwe ngaphambili.
