I-Climate Alliance, eyakhiwa ababusi abavela ezifundazweni ezingu-25 e-United States, imemezele ukuthi izokhuthaza ngamandla ukuthunyelwa kwamaphampu okushisa ayizigidi ezingu-20 ngo-2030. Lokhu kuzoba ngokuphindwe kane kwamaphampu okushisa ayizigidi ezingu-4.8 asevele efakiwe e-United States ngo-2020.

Njengendlela eyonga amandla esikhundleni sama-boilers kaphethiloli kanye nama-air conditioner, ama-heat pumps asebenzisa ugesi ukudlulisa ukushisa, kungaba ukushisa isakhiwo uma kubanda ngaphandle noma ukusipholisa uma kushisa ngaphandle. Ngokusho kwe-International Energy Agency, ama-heat pumps anganciphisa ukukhishwa kwegesi ebamba ukushisa ngo-20% uma kuqhathaniswa nama-gas boilers, futhi anganciphisa ukukhishwa kwegesi ngo-80% uma kusetshenziswa ugesi ohlanzekile. Ngokusho kwe-International Energy Agency, imisebenzi yokwakha ithatha u-30% wokusetshenziswa kwamandla emhlabeni wonke kanye no-26% wokukhishwa kwegesi ebamba ukushisa okuhlobene namandla.

Amaphampu okushisa angasindisa futhi abathengi imali. I-International Energy Agency ithi ezindaweni ezinamanani aphezulu egesi yemvelo, njengaseYurophu, ukuba nephampu yokushisa kungonga abasebenzisi cishe amaRandi angu-900 ngonyaka; e-United States, konga cishe amaRandi angu-300 ngonyaka.

Izifundazwe ezingu-25 ezizofaka amaphampu okushisa ayizigidi ezingu-20 ngo-2030 zimele u-60% womnotho wase-US kanye no-55% wabantu. “Ngikholwa ukuthi bonke abaseMelika banamalungelo athile, futhi phakathi kwawo kukhona ilungelo lokuphila, ilungelo lenkululeko kanye nelungelo lokulandela amaphampu okushisa,” kusho uMbusi Wesifundazwe saseWashington uJay Inslee, ongumDemocrat. “Isizathu sokuthi lokhu kubaluleke kangaka kwabaseMelika silula: Thina Sifuna ubusika obufudumele, sifuna ihlobo elipholile, sifuna ukuvimbela ukuwohloka kwesimo sezulu unyaka wonke. Akukho okusunguliwe okukhulu okufikile emlandweni wesintu kunephampu yokushisa, hhayi nje ngoba ingafudumala ebusika kodwa futhi ipholile ehlobo.” UK Slee uthe ukuqanjwa kwale ntsha enkulu kunazo zonke “kwakuyishwa kancane” ngoba yize yayibizwa ngokuthi “iphampu yokushisa,” empeleni ingafudumala futhi ipholile.

Izifundazwe ze-US Climate Alliance zizokhokhela lokhu kufakwa kwamaphampu okushisa ngezikhuthazo zezimali ezifakwe kuMthetho Wokunciphisa Ukwehla Kwamanani Ezinto Ezimbi, uMthetho Wokutshalwa Kwezimali Nemisebenzi Yengqalasizinda, kanye nemizamo yenqubomgomo yesifundazwe ngasinye esibambisene. Isibonelo, iMaine ibe nempumelelo enkulu ekufakeni amaphampu okushisa ngesenzo sayo somthetho.
