Zovuta za kusintha kwa nyengo zabweretsa chidwi chatsopano pakukula kwamagetsi opangira magetsi amadzi monga chotheka cholowa m'malo mwa magetsi kuchokera kumafuta oyambira.Pakali pano mphamvu ya Hydropower imapanga pafupifupi 6% ya magetsi opangidwa ku United States, ndipo kupanga magetsi kuchokera kumagetsi amadzi kumatulutsa mpweya wopanda mpweya.Komabe, popeza zambiri zazikuluzikulu zopangira magetsi opangira magetsi pamadzi zapangidwa kale, njira yabwino yopangira mphamvu zopangira magetsi ang'onoang'ono ndi otsika mphamvu yamadzi ingakhalepo.
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 zokhudzidwa ndi 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 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) osakwana mamita asanu (pafupifupi mapazi 16).
Malo opangira magetsi opangira madzi mumtsinje wa Run-of-River nthawi zambiri amadalira kuyenda kwachilengedwe kwa 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'makina operekera madzi ndi mafakitale kuti achepetse kuchulukana kwamadzimadzi mu valavu kapena kuchepetsa kuthamanga mpaka pamlingo woyenera kugwiritsidwa ntchito ndi makasitomala amadzi amapereka mwayi wowonjezera wopangira magetsi.
Mabilu angapo omwe akudikirira ku Congress kuti achepetse kusintha kwanyengo komanso mphamvu zoyera akufuna kukhazikitsa mulingo wamagetsi osinthika (kapena magetsi) (RES).Chotsogola 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 apano, RES idzafuna ogulitsa magetsi ogulitsa kuti apeze kuchuluka kwa magetsi ongowonjezedwa mphamvu zomwe amapereka kwa makasitomala.Ngakhale mphamvu yamadzi nthawi zambiri imawonedwa ngati gwero lamphamvu lamagetsi amagetsi, umisiri wa hydrokinetic (omwe amadalira madzi osuntha) komanso kugwiritsa ntchito mphamvu zochepa kwa mphamvu yamadzi 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 ayikidwa pamadamu omwe alipo omwe siamagetsi.
Potengera kukula kwa mapulojekiti ocheperako poyerekeza ndi mtengo wopangira magetsi opangira magetsi ang'onoang'ono komanso otsika, mitengo yolimbikitsira magetsi yomwe imapangidwa pakapita nthawi ikhoza kukulitsa kuthekera kwa polojekiti potengera kugulitsa magetsi.Momwemonso, ndi mfundo zoyendetsera magetsi monga dalaivala, zolimbikitsa za boma zitha kukhala zothandiza.Kupititsa patsogolo kupititsa patsogolo mphamvu zamagetsi ang'onoang'ono ndi otsika pamadzi pamlingo waukulu kuyenera kubwera chifukwa cha ndondomeko ya dziko yolimbikitsa zolinga za magetsi abwino.
