Amandla obushushu elanga abekelwe bucala ekuphuhlisweni kwe- umoya ovuselelekayo. Ukuyekiswa kwecandelo lokuthengiswa kwezindlu nomhlaba kulithintele eli candelo ukuba likhule kwizinga elilindelwe nguRhulumente le-5 yezigidi zeepawoti zesola zesicwangciso se2-2005.
Nokuba ukufakwa kwiKhowudi yoKwakha yobuGcisa, i-CTE, ukusukela ngo-2006, koxanduva lokufaka iiphaneli zelanga kumakhaya amatsha okanye kwizakhiwo ezihlaziyiweyo khange kube luncedo ekufakeleni iiphaneli zelanga ezininzi eSpain. I-CTE ifuna ukuba phakathi kwe-30 kunye ne-70 yeepesenti yokusetyenziswa kwe amanzi ashushu yamakhaya amatsha avela kumanzi acocekileyo afudunyezwe ngeepaneli zelanga, kodwa umlinganiso uwele ezindlebeni ezingevayo ngenxa yokungabikho kolwakhiwo olutsha. Ngokwenxalenye yayo, ngaphezulu kwamabhunga esixeko angama-50 kulo lonke elaseSpain nawo anemigaqo enomlinganiso ofanayo.
Le meko yenze iinkampani zamandla obushushu elanga, ngenkxaso ye-IDAE, ziguqula ukujonga kwazo kwenye indawo yoluntu enokuthi ifune olu hlobo lwamandla okanye inokuyisebenzisa kolunye usetyenziso. Kulapho ezinye izakhiwo ezifana izibhedlele, Iindawo zokuhlala zeeterecera ubudala nangaphezulu kumaziko okuthenga Unokuba ngabathengi beli hlobo lamandla ahlaziyekayo. Ukongeza, iteknoloji ekwaziyo ukwenza amandla elanga abe nenzuzo kungekuphela nje ukufumana amanzi ashushu nombane, kodwa kwanokupholisa, kuyakhuthazwa, Oko kukuthi, kungekuphela nje ubushushu kodwa nobushushu.
Ngokwe-IDAE, amandla eshushu elanga anokuwanelisa Iipesenti ezingama-80 zamanzi ashushu asekhaya asetyenziswa sisibhedlele kunye neepesenti ezingama-60 zamandla ombane afunekayo ukufudumeza esi sakhiwo.
La maziko ezempilo anokufikelela kwinkxaso-mali kunye noncedo olunikezelwa yi-IDAE kunye noluntu oluzimeleyo, ngamanye amaxesha ukuya kuthi ga kwiipesenti ezingama-40 zenani lilonke elityaliweyo, olu ncedo lunyuka. Ezi zibonelelo zahlukile kwiphondo ngalinye.
