Bazi reUS Energy Information Administration (EIA) nguva pfupi yadarika rakaburitsa gwaro rinoti kubva muchirimo chegore rino, kunze kwekuoma kwemamiriro okunze kwakatekeshera muUnited States, izvo zvakonzera kuti magetsi adzike munzvimbo dzakawanda munyika kwemwedzi inoverengeka yakatevera. Kune kushomeka kwemagetsi mudunhu, uye grid redunhu riri pasi pekumanikidzwa kukuru.
Kugadzirwa kwemagetsi emagetsi kunodzikira kwemwedzi
EIA yakataura kuti kuoma kwemamiriro okunze kwakanyanya uye kusina kujairika kwakakanganisa nzvimbo zhinji dzekumadokero kweUnited States, kunyanya nyika zhinji dziri muPacific Northwest. Aya matunhu ndimo mune mazhinji eUS hydropower akaiswa simba. Zvinotarisirwa kuti izvi zvichakonzera kuderera kwegore negore kwekugadzirwa kwemagetsi emvura muUnited States gore rino. 14%.
Zvinonzwisiswa kuti mumatunhu mashanu eWashington, Idaho, Vermont, Oregon neSouth Dakota, ingangoita hafu yemagetsi mudunhu rega rega inobva kumagetsi emvura. Muna Nyamavhuvhu gore rapfuura, California, iyo ine 13% yeUS yakaiswa simba remagetsi, yakamanikidzwa kuvhara Edward Hyatt hydropower station mushure mekunge mwero wemvura weLake Oroville wadonha kusvika pakuderera kwenhoroondo. Zviuru zvemhuri zvinopa magetsi akakwana. Kubva munaNovember gore rapfuura, simba remvura reCalifornia rakanga radzika kusvika pamakore gumi.
Dhamu reHoover, iro rinonyanya kushandiswa kwemagetsi munyika dzekumadokero, rakaisa mvura yakaderera kubva pakupedzwa kwayo muzhizha rino, uye simba rayo rekugadzira rakadonha ne25% kusvika ikozvino gore rino.
Pamusoro pezvo, mwero wemvura weLake Powell pamuganhu uri pakati peArizona neUtah uri kuramba uchidzikira. EIA inofanotaura kuti izvi zvichatungamira kune 3% mukana wekuti Dhamu reGlen Canyon haringakwanise kugadzira magetsi pane imwe nguva gore rinouya, uye mukana we34% wekuti harizokwanise kugadzira magetsi muna 2023.Kumanikidzwa kwegridhi remagetsi redunhu kunowedzera zvakanyanya
Kudonha kwakaerekana kwekugadzirwa kwemagetsi emvura kwaisa dzvinyiriro huru pakushanda kwegedhi remagetsi redunhu reUS. Iyo yazvino grid system yeUS inonyanya kuumbwa matatu makuru akasanganiswa emagetsi magidhi kumabvazuva, kumadokero, uye kumaodzanyemba kweTexas. Aya matatu akasanganiswa emagetsi magridi akabatanidzwa neashoma mashoma-anokwanisa DC mitsetse, inoverengera 73% uye 19% yemagetsi anotengeswa muUnited States, zvichiteerana. Uye 8%.
Pakati pavo, girasi remagetsi rekumabvazuva riri pedyo nenzvimbo huru yemarasha uye gasi muUnited States, uye inonyanya kushandisa marasha uye gasi rechisikiro pakugadzira magetsi; giredhi remagetsi rekumadokero riri pedyo nemakomo nenzizi dzeColorado, uye rinogoverwa nemakomo ane matombo nemamwe makomo ane nzvimbo huru, kunyanya hydropower. Main; iyo yekumaodzanyemba kweTexas magetsi gidhi iri mushale gasi bheseni, uye gasi rechisikigo simba rekugadzira ndiro rine simba, richigadzira yakazvimirira diki gidhi remagetsi mudunhu.
US media CNBC yakataura kuti giredhi remagetsi rekumavirira, iro rinonyanya kuvimba nehydropower, rakawedzera kuwedzera basa rayo rekushandisa. Dzimwe nyanzvi dzakaratidza kuti Western Power Grid inoda nekukurumidza kutarisana neramangwana rekudonha kamwe kamwe muhydropower.
EIA data inoratidza kuti hydropower iri pachishanu muUS simba chimiro, uye mugove wayo wakadzikira kubva pa7.25% gore rapfuura kusvika 6.85%. Muhafu yekutanga yegore rino, hydroelectric simba rekugadzira muUnited States rakadonha 12.6% gore negore.
Hydropower ichiri kukosha
"Dambudziko guru ratinosangana naro nderekutsvaga chiwanikwa chakakodzera kana musanganiswa wezviwanikwa kuti tipe simba uye simba rekubuda kwemagetsi rakaenzana nemagetsi emvura." Mutauriri weCalifornia Energy Commission Lindsay Buckley akati, "Sezvo shanduko yemamiriro ekunze ichitungamira kune yakanyanyisa mamiriro ekunze Nekuwedzera kuwanda, vanoita magidhi vanofanirwa kukurumidza kuenderana nekushanduka kukuru kwekugadzira magetsi emagetsi."
EIA yakataura kuti hydropower isimba rinogoneka kudzokororwa rine simba rekutevera uye kuita zvemitemo, uye rinogona kubatidzwa nekudzima zviri nyore. Nokudaro, inogona kushanda zvakanaka nemhepo inopindirana uye simba remhepo. Munguva iyi, hydropower inogona kuderedza zvakanyanya kuoma kwekuita kwegridi. Izvi zvinoreva kuti hydropower ichiri kukosha kuUnited States.
Severin Borenstein, nyanzvi yezvesimba remagetsi paYunivhesiti yeCalifornia kuBerkeley uye nhengo yebhodhi revatungamiriri veCalifornia vanozvimiririra magetsi emagetsi, akati: "Hydropower chikamu chakakosha chebasa rese rekubatana kwesimba remagetsi, uye chinzvimbo chayo chakakosha."
Zvinonzi pari zvino, kudonha kwakaerekana kwekugadzirwa kwemagetsi emvura kwakamanikidza makambani anoshandiswa neveruzhinji uye magridi ehurumende munzvimbo zhinji dzekumadokero kweUnited States kutsvaga mamwe manyuko ekugadzira magetsi, semafuta efossil, simba renyukireya, uye simba remhepo nezuva. "Izvi zvinotungamira kune yakakwira mitengo yekushandisa kune zvishandiso." Nathalie Voisin, injinjiniya yemvura yekuLos Angeles, akataura pachena. "Hydropower pakutanga yaive yakavimbika, asi mamiriro azvino anotimanikidza kutsvaga mhinduro nekukurumidza."
