Kutshanje, abaphathi beBiden balungiselela ukuphumeza isithintelo kwilizwe lonke kwiibhalbhu ezisetyenziswa ngokuqhelekileyo njengenxalenye yokusebenza kakuhle kwamandla kunye ne-ajenda yemozulu.
Imigaqo, ethintela abathengisi ekuthengiseni iiglowubhu ze-incandescent, yagqityezelwa liSebe lezaMandla (i-DOE) ngo-Epreli wama-2022 kwaye kulindeleke ukuba iqalise ukusebenza ngomhla woku-1 ku-Aug. 2023. I-DOE iya kuqalisa ukunyanzeliswa ngokupheleleyo kokuvalwa , kodwa sele ikhuthaze abathengisi ukuba baqale ukutshintshela kude nohlobo lwebhalbhu yesibane kwaye baqalise ukukhupha izaziso ezilumkisayo kwiinkampani kwiinyanga zakutshanje.
"Ishishini lokukhanyisa lamkela iimveliso ezisebenza ngamandla, kwaye lo mlinganiso uya kukhawulezisa inkqubela phambili yokuhambisa ezona mveliso zibalaseleyo kubathengi baseMelika kunye nokwakha ikamva eliqaqambileyo," utshilo uNobhala wezaMandla uJennifer Granholm ngo-2022.
Ngokwesibhengezo se-DOE, imimiselo iya kugcina i-3 yeebhiliyoni zeerandi ngonyaka kwiibhili ezisetyenziswayo kubathengi kwaye inciphise ukukhutshwa kwekhabhoni nge-222 yezigidi zeetoni zeemetric kwiminyaka engamashumi amathathu ezayo.
Ngokwemigaqo, ii-incandescent kunye nezibane ze-halogen ezifanayo ziya kuthintelwa ngokuthanda i-diode ekhupha ukukhanya okanye i-LED.Ngelixa amakhaya ase-US aye atshintshela kwii-bulbs ze-LED ukususela ngo-2015, ngaphantsi kwe-50% yemizi echazwe kusetyenziswa ubukhulu becala okanye ngokukodwa ii-LED, ngokwezona ziphumo zamva nje ezivela kwi-Residence Energy Consumption Survey.
Idatha ye-federal ibonise, i-47% isebenzisa ubukhulu becala okanye ii-LED kuphela, i-15% isebenzisa ubukhulu becala i-incandescent okanye i-halogens, kwaye i-12% isebenzisa ubukhulu becala okanye yonke i-compact fluorescent (CFL), kunye nenye i-26 ebika ukuba akukho luhlobo lwebhalbhu oluphambili.NgoDisemba odlulileyo, i-DOE yazisa imithetho eyahlukileyo evala iibhalbhu ze-CFL, ivula indlela yokuba ii-LED zibe zizo kuphela iiglowubhu ezisemthethweni ezinokuthengwa.

Ngokwedatha yovavanyo, ii-LED zikwadume kakhulu kumakhaya anengeniso ephezulu, okuthetha ukuba imimiselo yamandla iya kubachaphazela kakhulu abantu baseMelika abarhola imivuzo ephantsi.Ngelixa i-54% yamakhaya anengeniso engaphezulu kwe-100,000 yeedola ngonyaka asebenzisa ii-LED, kuphela i-39% yamakhaya anengeniso ye-20,000 yeedola okanye ngaphantsi kwee-LED ezisetyenziswayo.
"Sikholelwa ukuba ii-bulbs ze-LED sele zifumaneka kubathengi abakhethayo ngaphezu kwee-incandescent bulbs ukuze kuqwalaselwe ngakumbi amandla," umanyano lweemarike zamahhala kunye namaqela abathengi abachasene nokuvalwa kwebhalbhu ye-incandescent wabhala kwileta yokuphawula kwi-DOE kunyaka odlulileyo.
"Nangona ii-LEDs zisebenza kakuhle kwaye zihlala zihlala ixesha elide kunezibane ze-incandescent, okwangoku zibiza ngaphezu kwee-incandescent bulbs kwaye zingaphantsi kwimisebenzi ethile efana nokucima," le leta yatsho kwakhona.
Ngama-39 ekhulwini kuphela amakhaya anengeniso ye-20,000 yeedola okanye ngaphantsi asebenzisa ii-LED ubukhulu becala okanye ngokukodwa, ngokutsho kwedatha yophando yendawo yokuhlala.(Eduardo Parra/Europa Press ngeGetty Images)
