Kusukela ngo-1776, i-United States isebenzise imithombo yamandla ehlukene njengamanye amazwe amaningi kule planethi, kodwa ngenxa yobukhulu bayo obukhulu, ingasebenza njengesibonelo, besilokhu sishintsha kanjani kusukela lapho kwakuyizinkuni kuze kufike ekusetshenzisweni kwamalahle, uwoyela noma igesi yemvelo njengamandla okubasa asetshenziswa kakhulu emlandweni wawo "omfushane" njengezwe.
Ishadi elivela ekuphathweni kwamandla e-US uqobo, singaqhuba ukubuyekeza okusheshayo kulokho obekusetshenziswa kwemithombo yamandla ehlukene kusukela ngo-1776 kwamenyezelwa njengesizwe.
Abathathu kube ngukaphethiloli abazuzile 80% ukusetshenziswa kwamandla eminyakeni engaphezu kwengu-100: uwoyela, igesi yemvelo namalahle. Ngalokhu kushiwo, futhi yize sibheka ukuthi izinto ezivuselelekayo zithatha kanjani isikhala sazo, le mithombo emithathu esuselwa kumathambo wezinsalela kubonakala sengathi izoba khona isikhashana.
Emashumini eminyaka okuqala omlando wase-US, kwasetshenziswa imindeni izinkuni njengomthombo oyinhloko wamandla. Amalahle adlondlobala ngasekupheleni kwekhulu le-XNUMX, ngaphambi kokuba kudlulwa yimikhiqizo eyenziwe ngophethiloli maphakathi nekhulu lama-XNUMX, ngesikhathi lapho igesi yemvelo yayiqala ukwanda ekusetshenzisweni.
Kusukela maphakathi nekhulu lama-XNUMX, ukusetshenziswa kwamalahle kwaqala ukukhula, ikakhulukazi njengomthombo wamandla oyinhloko wokukhiqizwa kwamandla kagesi, nokuthi kungaba yini uhlobo olusha lwamandla afana nenuzi. Ngemuva kwe-hiatus ngeminyaka yama-70s, ukusetshenziswa kukawoyela negesi yemvelo kwabonakala kumile, yize igesi yemvelo yahamba ngendlela yayo.
I-Las amandla avuselelekayo aqhuma kuma-80s ne-hydroelectric njengomdlali ophambili kule ndawo yamandla ahlanzekile, ngokwanda okuphawulekayo maphakathi neshumi leminyaka lokuqala lekhulu lama-2014. Ngo-10, ukusetshenziswa kwezinto ezivuselelekayo kuholele kumaphesenti aphezulu emlandweni wezwe ngo-XNUMX%.
Lokhu kuvula indlela yokuvuselelwa kabusha njengokuhlanganiswa kwamandla okulindeleke qhubeka ukhuphule lelo phesenti sibonga ilanga noma umoya ngokubambisana ne-biomass ne-geothermal, futhi lokho kubalulekile ukunciphisa ukuthumela i-CO2 emkhathini.
