Tuam Tshoj tam sim no tsim thiab xa khoom ntau dua 80 feem pua ntawm lub ntiaj teb lub hnub ci photovoltaic (PV) vaj huam sib luag, ib daim ntawv tshaj tawm tshiab los ntawm International Energy Agency (IEA) tau hais.
Raws li cov phiaj xwm nthuav dav tam sim no, Tuam Tshoj yuav yog lub luag haujlwm rau 95 feem pua ntawm tag nrho cov txheej txheem tsim khoom los ntawm 2025.
Tuam Tshoj tau dhau los ua cov chaw tsim khoom ntawm PV vaj huam sib luag rau ob qho tib si hauv tsev thiab kev lag luam siv nyob rau hauv kaum xyoo dhau los, tshaj Europe, Nyiv thiab Tebchaws Meskas, uas tau ua haujlwm dhau los hauv PV cov khoom lag luam.
Raws li IEA, Xinjiang xeev ntawm Tuam Tshoj yog lub luag haujlwm rau ib ntawm xya lub hnub ci vaj huam sib luag tsim thoob ntiaj teb.Tsis tas li ntawd, tsab ntawv ceeb toom ceeb toom rau tsoomfwv thiab cov neeg tsim cai thoob plaws ntiaj teb los ua haujlwm tawm tsam Tuam Tshoj txoj kev tswj hwm ntawm cov saw hlau.Daim ntawv tshaj tawm kuj qhia txog ntau yam kev daws teeb meem rau lawv kom pib tsim khoom hauv tsev.
Daim ntawv tshaj tawm qhia txog tus nqi tsim nyog raws li qhov laj thawj tseem ceeb cuam tshuam rau lwm lub tebchaws los ntawm kev nkag mus rau cov saw hlau.Hais txog kev ua haujlwm, nyiaj siv ua haujlwm thiab tag nrho cov txheej txheem tsim khoom, Tuam Tshoj tus nqi qis dua 10% piv rau Is Nrias teb.Tag nrho cov txheej txheem tsim khoom yog 20 feem pua pheej yig dua piv rau cov nqi hauv Tebchaws Meskas thiab 35 feem pua ntawm cov teb chaws Europe qis dua.
Raw Material Shortage
Txawm li cas los xij, tsab ntawv ceeb toom tau lees paub tias Tuam Tshoj txoj kev ua raws li cov saw hlau yuav dhau los ua qhov teeb meem loj dua thaum lub teb chaws txav mus rau net-zero emissions vim nws tuaj yeem ua rau muaj kev xav tau thoob ntiaj teb rau PV panels thiab cov khoom siv raw.
IEA tau hais
Hnub ci PV qhov kev thov rau cov zaub mov tseem ceeb yuav nce sai hauv txoj hauv kev mus rau net-zero emissions.Kev tsim cov khoom siv tseem ceeb hauv PV yog cov concentrated, nrog Tuam Tshoj ua lub luag haujlwm tseem ceeb.Txawm hais tias kev txhim kho hauv kev siv cov khoom siv tau zoo dua, PV kev lag luam qhov kev thov rau cov ntxhia tau tsim los nthuav dav.
Ib qho piv txwv hais los ntawm cov kws tshawb fawb yog qhov kev thov nce ntxiv rau cov nyiaj uas yuav tsum tau ua rau hnub ci PV tsim.Cov pob zeb tseem ceeb qhov kev thov yuav yog 30 feem pua siab dua li tag nrho cov nyiaj txiag thoob ntiaj teb los ntawm 2030, lawv tau hais.
"Qhov kev loj hlob sai no, ua ke nrog lub sijhawm ua haujlwm ntev rau cov haujlwm mining, ua rau muaj kev pheej hmoo ntawm kev xa khoom thiab kev thov tsis sib haum, uas tuaj yeem ua rau tus nqi nce thiab cov khoom tsis txaus," cov kws tshawb fawb tau piav qhia.
Tus nqi ntawm polysilicon, lwm yam khoom siv tseem ceeb los ua PV panels, nce siab thaum muaj kev sib kis, thaum ntau lawm poob.Tam sim no nws yog ib qho kev tsis sib haum xeeb hauv cov saw hlau vim tias nws qhov kev tsim khoom raug txwv, lawv tau hais.
Qhov muaj ntawm wafers thiab hlwb, lwm cov khoom xyaw tseem ceeb, tshaj qhov xav tau los ntawm ntau dua 100 feem pua hauv 2021, cov kws tshawb fawb ntxiv.
Txoj Kev Forward
Daim ntawv tshaj tawm qhia txog qhov muaj peev xwm txhawb nqa uas lwm lub tebchaws tuaj yeem muab los tsim PV cov saw hlau ntawm lawv tus kheej kom txo tau qhov tsis muaj kev vam khom rau Tuam Tshoj.
Raws li IEA, cov teb chaws thoob plaws ntiaj teb tuaj yeem pib los ntawm kev pab nyiaj ncaj qha rau ntau yam nqi koom nrog hauv hnub ci PV tsim los txhim kho kev lag luam thiab ua kom lawv txoj kev loj hlob.
Thaum Tuam Tshoj pom lub sijhawm hauv kev loj hlob ntawm nws txoj kev lag luam thiab kev xa tawm thaum ntxov 2000s, cov tuam txhab tsim khoom hauv tsev tau txais kev txhawb nqa los ntawm cov nyiaj qiv qis thiab nyiaj pab.
Ib yam li ntawd, IEA cov lus taw qhia txhawm rau txhawb nqa cov khoom siv hauv tsev PV suav nrog cov se qis lossis cov nqi ntshuam rau cov khoom siv tuaj txawv teb chaws, muab cov qhab nia se peev, nyiaj pab them nqi hluav taws xob thiab muab nyiaj rau kev ua haujlwm thiab lwm yam haujlwm.
