Bazi reUS Energy Information Administration (EIA) nguva pfupi yadarika rakaburitsa gwaro rinoti kubva muchirimo chegore rino, kunze kwekusanaya kwemvura kwakanyanya munyika yeAmerica, 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 kudzikira kwegore negore kwekugadzirwa kwemagetsi emagetsi 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 zvino gore rino.
Pamusoro pezvo, mwero wemvura weLake Powell pamuganhu uri pakati peArizona neUtah uri kuramba uchidzikira.EIA inofanotaura kuti izvi zvichaita kuti pave nemukana we3% wekuti Dhamu reGlen Canyon haringakwanise kugadzira magetsi pane imwe nguva gore rinouya, uye mukana we34% wekuti harizokwanise kugadzira magetsi muna2023.Kudzvinyirirwa kwegridi 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-ashoma-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;iyo yekumadokero magetsi grid iri pedyo neColorado makomo nenzizi, uye inogoverwa nemakomo ane matombo nemamwe makomo ane nzvimbo huru, kunyanya hydropower.Main;iyo yekumaodzanyemba Texas magetsi gidhi iri mushale gasi bheseni, uye gasi rechisikigo simba rekugadzira ndiro rinonyanya kutonga, richigadzira yakazvimirira diki gidhi remagetsi mudunhu.
Vezvenhau veUS CNBC vakaratidza kuti gidhi remagetsi rekumavirira, iro rinonyanya kuvimba nehydropower, rakawedzera kuwedzera basa rayo.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 7.25% gore rapfuura kusvika 6.85%.Muhafu yekutanga yegore rino, hydroelectric simba rekugadzira muUnited States rakadonha 12.6% gore-pagore.
Hydropower ichiri kukosha
"Dambudziko guru ratinosangana naro nderekutsvaga chitubu 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 kudzoreredza zvakanyanya kuoma kwekuita kwegridi.Izvi zvinoreva kuti hydropower ichiri kukosha kuUnited States.
Severin Borenstein, nyanzvi yezvesimba remagetsi paUniversity yeCalifornia kuBerkeley uye ari nhengo yebhodhi revatungamiriri veCalifornia vanozvimiririra magetsi emagetsi, akati: “Hydropower chikamu chakakosha chekushanda pamwe kwesimba rese remagetsi, uye chinzvimbo chayo zvakakosha zvikuru.”
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 mhepo nesolar. simba."Izvi zvinotungamira kune yakakwira mitengo yekushandisa kune zvishandiso."Nathalie Voisin, injinjiniya yemvura yekuLos Angeles, akataura pachena."Hydropower pakutanga yaive yakavimbika, asi mamiriro aripo anotimanikidza kutsvaga mhinduro nekukurumidza."
