I-US Energy Information Administration (EIA) isanda kukhipha umbiko othi kusukela ehlobo lalo nyaka, isimo sezulu esomile esibi sihlasele e-United States, okubangele ukwehla kwamandla kagesi ezindaweni eziningi zezwe izinyanga ezimbalwa zilandelana.Kukhona ukushoda kukagesi esifundazweni, futhi igridi yesifunda ingaphansi kwengcindezi enkulu.
Ukukhiqizwa kwamandla kagesi kuyehla izinyanga
I-EIA iveze ukuthi isimo sezulu esomile esibi kakhulu nesingejwayelekile sithinte izingxenye eziningi zasentshonalanga ye-United States, ikakhulukazi izifundazwe eziningi ezisePacific Northwest.Lezi zifunda kulapho iningi lamandla afakwe emanzini ase-US atholakala khona.Kulindeleke ukuthi lokhu kuzoholela ekwehleni konyaka nonyaka ukuphehlwa kukagesi ngamanzi e-United States kulo nyaka.14%.
Kuyaqondakala ukuthi ezifundazweni ezinhlanu zaseWashington, Idaho, Vermont, Oregon kanye neSouth Dakota, okungenani uhhafu kagesi esifundazweni ngasinye uvela kumandla aphehlwa ngamanzi.Ngo-Agasti nyakenye, iCalifornia, engumnikazi we-13% womthamo wokuphehlwa ngamanzi afakwe e-US, yaphoqeleka ukuthi ivale isiteshi sikagesi i-Edward Hyatt ngemuva kokuba izinga lamanzi eLake Oroville lehle kakhulu emlandweni.Izinkulungwane zemizi zihlinzeka ngogesi owanele.Kusukela ngoNovemba wonyaka odlule, amandla kagesi waseCalifornia ehle afinyelela eminyakeni eyi-10.
Idamu i-Hoover, eliwumthombo oyinhloko wokusetshenziswa kukagesi ezifundazweni zasentshonalanga, libeke izinga eliphansi lamanzi kusukela laqedwa kuleli hlobo, futhi ukukhiqizwa kwalo kukagesi kwehle ngama-25% kuze kube manje kulo nyaka.
Ngaphezu kwalokho, izinga lamanzi eLake Powell emngceleni ophakathi kwe-Arizona ne-Utah nalo liyaqhubeka nokwehla.I-EIA ibikezela ukuthi lokhu kuzoholela emathubeni angu-3% okuthi iDamu laseGlen Canyon ngeke likwazi ukukhiqiza ugesi esikhathini esithile ngonyaka ozayo, kanye namathuba angama-34% okuthi lingakwazi ukukhiqiza ugesi ngo-2023.Ingcindezi kugridi yamandla wesifunda ikhuphuka kakhulu
Ukwehla kungazelelwe kokuphehlwa kukagesi ngamanzi sekufake ingcindezi enkulu ekusebenzeni kwegridi kagesi yesifunda sase-US.Uhlelo lwamanje lwegridi yase-US lwakhiwe ngokuyinhloko amagridi amakhulu amathathu ahlanganisiwe empumalanga, entshonalanga, naseningizimu ye-Texas.Lawa magridi kagesi amathathu ahlanganisiwe axhunywe imigqa embalwa kuphela ye-DC yamandla aphansi, ebalwa ku-73% no-19% kagesi othengiswa e-United States, ngokulandelana.Futhi 8%.
Phakathi kwazo, igridi yamandla asempumalanga iseduze nezindawo ezinkulu zokuhlinzeka ngamalahle negesi e-United States, futhi ikakhulukazi isebenzisa amalahle negesi yemvelo ukukhiqiza ugesi;igridi yamandla asentshonalanga iseduze nezintaba nemifula yaseColorado, futhi isakazwa ngezintaba ezinamatshe nezinye izintaba ezinendawo enkulu, ikakhulukazi amandla aphehlwa ngamanzi.Okuyinhloko;igridi yamandla eseningizimu ye-Texas itholakala endaweni yegesi ye-shale, futhi ukukhiqizwa kwamandla egesi yemvelo yikhona okuvelele, kwakha igridi yamandla amancane ezimele esifundeni.
Imithombo yezindaba yase-US i-CNBC iveze ukuthi igridi yamandla asentshonalanga, ethembele kakhulu kugesi ophehlwa ngamanzi, iye yandisa umthwalo wayo wokusebenza.Abanye ochwepheshe baveze ukuthi i-Western Power Grid idinga ngokushesha ukubhekana nekusasa lokwehla kungazelelwe kophehlwa ngamanzi.
Idatha ye-EIA ikhombisa ukuthi amandla kagesi akleliswe endaweni yesihlanu esakhiweni samandla saseMelika, futhi isabelo sawo sehle sisuka ku-7.25% ngonyaka odlule saya ku-6.85%.Engxenyeni yokuqala yalo nyaka, ukukhiqizwa kwamandla kagesi ngamanzi e-United States kwehle ngo-12.6% unyaka nonyaka.
Amandla kagesi asabalulekile
“Inselelo enkulu esibhekene nayo ukuthola insiza efanelekile noma inhlanganisela yezinsiza ukunikeza amandla namandla okukhipha amandla alingana nogesi ophehlwa ngamanzi.”Umkhulumeli weKhomishini Yezamandla yaseCalifornia uLindsay Buckley uthe, "Njengoba ukuguquka kwesimo sezulu kuholela esimweni sezulu esibi kakhulu Ngokukhula kwemvamisa, abasebenzisa igridi kufanele basheshise ukuze bavumelane nokuguquguquka okukhulu kokukhiqizwa kwamandla kagesi."
I-EIA iveze ukuthi amandla aphehlwa ngamanzi angamandla avuselelekayo ashintshashintshayo anokulandelela okuqinile komthwalo nokusebenza kokulawula, futhi angavulwa futhi acinywe kalula.Ngakho-ke, ingasebenza kahle ngezikhawu zomoya namandla omoya.Ngaleso sikhathi, amandla kagesi angadambisa kakhulu inkimbinkimbi yokusebenza kwegridi.Lokhu kusho ukuthi ugesi ophehlwa ngamanzi usabalulekile e-United States.
USeverin Borenstein, uchwepheshe wamandla avuselelekayo eNyuvesi yaseCalifornia eBerkeley futhi oyilungu lebhodi labaqondisi babasebenzi besistimu yamandla ezimele yaseCalifornia, uthe: “I-Hydropower iyingxenye ebalulekile yomsebenzi wokusebenzisana wesistimu yonke yamandla, futhi indima yayo baluleke kakhulu."
Kubikwa ukuthi okwamanje, ukwehla okungazelelwe kokuphehlwa kukagesi ngamanzi kuye kwaphoqa izinkampani zomphakathi kanye nabaphathi begridi kahulumeni ezifundazweni eziningi zasentshonalanga ye-United States ukuba bafune eminye imithombo yokuphehla ugesi, njengamafutha ezinto ezimbiwa phansi, amandla enuzi, nomoya nelanga. amandla."Lokhu kuholela ngokungaqondile ezindlekweni zokusebenza eziphezulu zezinsiza."UNathalie Voisin, unjiniyela wemithombo yamanzi e-Los Angeles, washo ngokungananazi."Amandla kagesi ekuqaleni ayethembeke kakhulu, kodwa isimo samanje siyasiphoqa ukuthi sithole isixazululo ngokushesha okukhulu."
