Ishyirahamwe ry’Imihindagurikire y’Ikirere, rigizwe n’abayobozi ba leta 25 muri Leta Zunze Ubumwe za Amerika, ryatangaje ko rizashyigikira cyane ishyirwaho ry’imashini zishyushya miliyoni 20 mu 2030. Ibi bizaba bikubye inshuro enye imashini zishyushya miliyoni 4.8 zari zimaze gushyirwa muri Leta Zunze Ubumwe za Amerika mu 2020.

Ubundi buryo bwo gukoresha ingufu nke kuruta ibyuma bishyushya ibikomoka kuri peteroli n'ibyuma bikonjesha, pompe zishyushya zikoresha amashanyarazi mu kohereza ubushyuhe, haba mu gushyushya inyubako iyo ikonje hanze cyangwa mu kuyikonjesha iyo ishyushye hanze. Nk’uko Ikigo Mpuzamahanga Gishinzwe Ingufu kibitangaza, pompe zishyushya zishobora kugabanya imyuka ihumanya ikirere ku kigero cya 20% ugereranije n’ibyuma bishyushya ibikomoka kuri peteroli, kandi zishobora kugabanya imyuka ihumanya ikirere ku kigero cya 80% iyo zikoresha amashanyarazi meza. Nk’uko Ikigo Mpuzamahanga Gishinzwe Ingufu kibitangaza, ibikorwa by’inyubako bigira 30% by’ingufu zikoreshwa ku isi na 26% by’imyuka ihumanya ikirere ikomoka ku ngufu.

Pompe zishyushya zishobora kandi kuzigama amafaranga y'abaguzi. Ikigo Mpuzamahanga Gishinzwe Ingufu kivuga ko ahantu hafite ibiciro biri hejuru bya gaze karemano, nko mu Burayi, gutunga pompe zishyushya bishobora kuzigama abakoresha amafaranga agera ku madolari 900 ku mwaka; muri Leta Zunze Ubumwe za Amerika, bizigama agera ku madolari 300 ku mwaka.

Leta 25 zizashyiraho pompe zishyushya miliyoni 20 bitarenze umwaka wa 2030 zigize 60% by'ubukungu bwa Amerika na 55% by'abaturage. Guverineri wa Leta ya Washington Jay Inslee, umudemokarate, yagize ati: “Ndizera ko Abanyamerika bose bafite uburenganzira bumwe na bumwe, kandi muri bwo harimo uburenganzira bwo kubaho, uburenganzira bwo kwisanzura no gukurikirana pompe zishyushya.” “Impamvu ibi ari ingenzi ku Banyamerika ni uko: Twebwe, turashaka ibihe by'ubushyuhe, twifuza ibihe by'impeshyi bikonje, dushaka gukumira ihungabana ry'ikirere umwaka wose. Nta gishya gikomeye cyabayeho mu mateka y'abantu kurusha pompe ishyushya, atari ukubera ko ishobora gushyuha mu gihe cy'itumba gusa ahubwo no gukonja mu mpeshyi.” UK Slee yavuze ko kwitwa iki gishya gikomeye kurusha ibindi byose “byari bibabaje gato” kuko nubwo cyitwaga “pompe ishyushya,” mu by'ukuri ishobora gushyuha ndetse no gukonja.

Ibihugu biri mu Muryango w’Ubumwe bw’Isi Ushinzwe Imihindagurikire y’Ikirere bizishyura izi pompe zishyushya binyuze mu nkunga y’imari ikubiye mu Itegeko ryo Kugabanya Izamuka ry’Ibiciro, Itegeko ry’Ishoramari n’Umurimo mu bikorwa remezo, hamwe n’ingamba za politiki za buri leta iri mu Muryango. Urugero, Maine yagize intsinzi ikomeye mu gushyiraho pompe zishyushya binyuze mu bikorwa byayo by’amategeko.
