Zovuta za kusintha kwa nyengo zabweretsa chidwi chatsopano pakukula kwamagetsi opangira mphamvu yamadzi monga choloweza m'malo mwa magetsi kuchokera kumafuta oyambira. Pakali pano mphamvu ya Hydropower imapanga pafupifupi 6% ya magetsi opangidwa ku United States, ndipo kutulutsa magetsi kuchokera ku hydropower sikutulutsa mpweya wa carbon. Komabe, popeza zambiri zazikuluzikulu zopangira magetsi opangira magetsi pamadzi zapangidwa kale, njira yabwino yopangira mphamvu zopangira mphamvu zopangira magetsi ang'onoang'ono komanso otsika kwambiri.
Kupanga mphamvu kuchokera ku mitsinje ndi mitsinje sikukhala ndi mkangano, ndipo kuthekera kopanga mphamvu kuchokera ku magwerowa kuyenera kukhala koyenera motsutsana ndi chilengedwe ndi zinthu zina zokomera anthu. Kulinganiza kumeneko kungathandizidwe ndi kafukufuku wokhudza matekinoloje atsopano ndi malamulo oganiza zamtsogolo omwe amalimbikitsa chitukuko cha zinthuzi m'njira zotsika mtengo, zowononga zachilengedwe zomwe zimazindikira kuti malo oterowo, atamangidwa, akhoza kukhala zaka zosachepera 50.
Kafukufuku wotheka wochitidwa ndi Idaho National Laboratory mu 2006 adapereka kuwunika kwa kuthekera kopanga magetsi ang'onoang'ono komanso ang'onoang'ono opangira mphamvu zamagetsi ku United States. Pafupifupi malo 5,400 mwa 100,000 anatsimikiziridwa kukhala ndi kuthekera kopanga mapulojekiti ang'onoang'ono opangira madzi (ie, kupereka pakati pa 1 ndi 30 Megawatts ya mphamvu yapakati pachaka). Dipatimenti Yoona za Mphamvu ya ku United States inati mapulojekitiwa (ngati apangidwa) angapangitse kuti mphamvu zonse zopangira magetsi ziwonjezeke ndi 50%. Mphamvu yamadzi yotsika pang'ono imatanthawuza malo okhala ndi mutu (mwachitsanzo, kusiyana kokwera) kochepera mamita asanu (pafupifupi mapazi 16).
Malo opangira magetsi opangira madzi mumtsinje wa Run-of-River nthawi zambiri amadalira kayendedwe kachilengedwe ka mitsinje ndi mitsinje, ndipo amatha kugwiritsa ntchito madzi ang'onoang'ono oyenda popanda kufunikira komanga madamu akulu. Zida zomangira madzi m’ngalande monga ngalande, ngalande zothirira, ngalande, ndi mapaipi angagwiritsidwenso ntchito popanga magetsi. Ma valve ochepetsera mphamvu omwe amagwiritsidwa ntchito m'machitidwe operekera madzi ndi mafakitale kuti achepetse kuchulukana kwamadzimadzi mu valavu kapena kuchepetsa kupanikizika mpaka pamlingo woyenera kugwiritsidwa ntchito ndi makasitomala amadzi amapereka mwayi wowonjezera wopangira magetsi.
Mabilu angapo omwe akudikirira ku Congress kuti achepetse kusintha kwanyengo ndi mphamvu zoyera amafuna kukhazikitsa mulingo wamagetsi osinthika (kapena magetsi) (RES). Chachikulu pakati pa izi ndi HR 2454, American Clean Energy and Security Act ya 2009, ndi S. 1462, American Clean Energy Leadership Act ya 2009. Pansi pa malingaliro omwe alipo panopa, RES idzafuna ogulitsa magetsi ogulitsa kuti apeze kuchuluka kwa magetsi owonjezera mphamvu zomwe amapereka kwa makasitomala. Ngakhale mphamvu yamadzi nthawi zambiri imatengedwa ngati gwero loyera lamagetsi amagetsi, umisiri wa hydrokinetic (omwe amadalira madzi osuntha) komanso kugwiritsa ntchito mphamvu zochepa za hydropower kungayenerere RES. Poganizira chilankhulo chomwe chilipo pamabilu omwe akuyembekezera, sizingatheke kuti mapulojekiti ambiri atsopano oyendetsa mtsinje wapansi ndi ang'onoang'ono opangira mphamvu yamadzi akwaniritse zofunikira za "mphamvu yopangira mphamvu yamadzi" pokhapokha ngati mapulojekitiwa atayikidwa pamadamu omwe alipo omwe siamagetsi.
Potengera kukula kwa mapulojekiti ocheperako poyerekeza ndi ndalama zopangira magetsi ang'onoang'ono komanso otsika kwambiri, mitengo yolimbikitsira magetsi yomwe imapangidwa pakapita nthawi ingawonjezere kuthekera kwa projekiti potengera kugulitsa magetsi. Momwemonso, ndi ndondomeko yamagetsi yoyera ngati dalaivala, zolimbikitsa za boma zingakhale zothandiza. Kupititsa patsogolo kutukuka kwa mphamvu zamagetsi zazing'ono ndi zotsika pamadzi pamlingo waukulu zitha kubwera chifukwa cha mfundo za dziko zolimbikitsa zolinga zamphamvu zamagetsi.
