Lub US Energy Information Administration (EIA) tsis ntev los no tau tshaj tawm ib tsab ntawv ceeb toom hais tias txij li lub caij ntuj sov xyoo no, huab cua qhuav heev tau cheb Tebchaws Meskas, ua rau lub zog tsim hluav taws xob hauv ntau lub tebchaws poob rau ob peb lub hlis sib law liag.Muaj ib qho tsis txaus ntawm hluav taws xob hauv lub xeev, thiab cov phiaj xwm hauv cheeb tsam tau muaj kev ntxhov siab heev.
Kev tsim hluav taws xob hluav taws xob poob qis rau lub hlis
EIA tau taw qhia tias huab cua qhuav heev thiab txawv txav tau cuam tshuam rau feem ntau ntawm sab hnub poob Tebchaws Meskas, tshwj xeeb tshaj yog ntau lub xeev hauv Pacific Northwest.Cov xeev no yog qhov chaw feem ntau ntawm Teb Chaws Asmeskas hydropower nruab muaj peev xwm nyob.Nws cia siab tias qhov no yuav ua rau muaj kev poob qis hauv ib xyoos ntawm kev tsim hluav taws xob hauv Tebchaws Meskas xyoo no.14%.
Nws tau nkag siab tias hauv tsib lub xeev ntawm Washington, Idaho, Vermont, Oregon thiab South Dakota, tsawg kawg yog ib nrab ntawm cov hluav taws xob hauv txhua lub xeev los ntawm hydropower.Thaum lub Yim Hli xyoo tas los, California, uas yog tus tswv 13% ntawm Teb Chaws Asmeskas lub peev xwm tsim hluav taws xob, raug yuam kom kaw qhov chaw nres tsheb dej Edward Hyatt tom qab dej theem ntawm Lake Oroville poob rau keeb kwm qis.Ntau txhiab tsev neeg muab hluav taws xob txaus.Raws li lub Kaum Ib Hlis xyoo tas los, California lub peev xwm siv hluav taws xob tau poob mus rau 10-xyoo qis.
Hoover Dam, qhov tseem ceeb ntawm kev siv hluav taws xob hauv xeev sab hnub poob, tau teeb tsa cov dej qis tshaj plaws txij li nws ua tiav lub caij ntuj sov no, thiab nws cov hluav taws xob tsim hluav taws xob tau poob 25% txog rau tam sim no xyoo no.
Tsis tas li ntawd, cov dej theem ntawm Lake Powell ntawm ciam teb ntawm Arizona thiab Utah kuj tseem poob qis.EIA kwv yees tias qhov no yuav ua rau muaj 3% qhov tshwm sim uas Glen Canyon Dam yuav tsis muaj peev xwm tsim hluav taws xob rau xyoo tom ntej, thiab 34% qhov tshwm sim uas nws yuav tsis tuaj yeem tsim hluav taws xob hauv xyoo 2023.Lub siab ntawm daim phiaj hluav taws xob hauv cheeb tsam nce siab
Kev poob tam sim no hauv kev tsim hluav taws xob tau ua rau muaj kev ntxhov siab loj rau kev ua haujlwm ntawm US thaj av fais fab.Cov kab hluav taws xob tam sim no hauv Teb Chaws Asmeskas feem ntau yog tsim los ntawm peb lub zog loj sib xyaw ua ke nyob rau sab hnub tuaj, sab hnub poob, thiab sab qab teb Texas.Peb cov kab hluav taws xob ua ke no tau txuas nrog tsuas yog ob peb lub peev xwm DC kab, suav txog 73% thiab 19% ntawm cov hluav taws xob muag hauv Tebchaws Meskas, feem.Thiab 8%.
Ntawm lawv, daim phiaj hluav taws xob sab hnub tuaj nyob ze rau thaj chaw tseem ceeb ntawm cov thee thiab cov pa roj hauv Tebchaws Meskas, thiab feem ntau yog siv cov thee thiab cov nkev roj rau kev tsim hluav taws xob;daim phiaj hluav taws xob sab hnub poob yog nyob ze rau Colorado toj siab thiab cov dej ntws, thiab faib nrog cov roob pob zeb thiab lwm lub roob nrog cov struts zoo, feem ntau yog hydropower.Main;sab qab teb Texas lub zog hluav taws xob yog nyob rau hauv shale gas phiab, thiab cov roj hluav taws xob tsim hluav taws xob yog qhov tseem ceeb, tsim ib qho kev ywj pheej me me hluav taws xob hauv cheeb tsam.
Asmeskas xov xwm CNBC tau taw qhia tias sab hnub poob lub zog hluav taws xob, uas feem ntau yog nyob ntawm hydropower, tau nce ntxiv nws cov haujlwm ua haujlwm.Qee cov kws tshaj lij tau taw qhia tias Western Power Grid yuav tsum tau ntsib lub neej yav tom ntej ntawm kev poob qis hauv dej.
EIA cov ntaub ntawv qhia tau hais tias hydropower nyob rau qib tsib hauv Teb Chaws Asmeskas cov qauv hluav taws xob, thiab nws feem tau nqis los ntawm 7.25% xyoo tas los mus rau 6.85%.Hauv thawj ib nrab ntawm lub xyoo no, kev tsim hluav taws xob hauv Tebchaws Meskas tau poob 12.6% xyoo-rau-xyoo.
Hydropower tseem yog qhov tseem ceeb
"Qhov kev sib tw loj tshaj plaws uas peb ntsib yog nrhiav cov peev txheej tsim nyog lossis kev sib koom ua ke ntawm cov peev txheej los muab lub zog thiab lub zog tso tawm muaj peev xwm sib npaug rau hydropower."California Energy Commission tus kws tshaj lij Lindsay Buckley tau hais tias, "Raws li kev hloov pauv huab cua ua rau huab cua huab cua ntau dua Nrog kev nce zaus, cov neeg ua haujlwm hauv kab sib chaws yuav tsum tau ceev kom hloov mus rau qhov kev hloov pauv loj hauv kev tsim hluav taws xob hluav taws xob."
EIA tau taw qhia tias lub zog hluav taws xob yog lub zog txuas ntxiv hloov tau yooj yim nrog lub zog thauj khoom thiab kev tswj hwm kev ua tau zoo, thiab tuaj yeem hloov tau yooj yim thiab tawm.Yog li ntawd, nws tuaj yeem ua haujlwm zoo nrog kev sib tshuam cua thiab cua zog.Thaum lub sij hawm, hydropower tuaj yeem txo qhov nyuaj ntawm kev ua haujlwm ntawm kab sib chaws.Qhov no txhais tau hais tias hydropower tseem yog qhov tseem ceeb rau Tebchaws Meskas.
Severin Borenstein, tus kws tshaj lij hluav taws xob tauj dua tshiab ntawm University of California ntawm Berkeley thiab yog tus tswv cuab ntawm pawg thawj coj ntawm California cov neeg ua haujlwm ywj pheej hluav taws xob, tau hais tias: "Hydropower yog ib feem tseem ceeb ntawm tag nrho lub zog hluav taws xob kev sib koom ua haujlwm, thiab nws txoj haujlwm ua haujlwm yog. tseem ceeb heev. "
Nws tau tshaj tawm tias tam sim no, kev poob qis hauv kev tsim hluav taws xob tam sim no tau yuam cov tuam txhab siv hluav taws xob pej xeem thiab cov neeg ua haujlwm hauv xeev hauv ntau lub xeev sab hnub poob hauv Tebchaws Meskas kom nrhiav lwm qhov chaw tsim hluav taws xob, xws li fossil fuels, nuclear fais fab, thiab cua thiab hnub ci. zog."Qhov no tsis ncaj qha ua rau cov nqi khiav lag luam ntau dua rau kev siv hluav taws xob."Nathalie Voisin, tus kws tshaj lij dej hauv Los Angeles, tau hais ncaj qha."Hydropower yog Ameslikas ntseeg tau heev, tab sis qhov xwm txheej tam sim no yuam kom peb nrhiav kev daws sai li sai tau."
