Lub koom haum International Energy Agency (IEA) tau hais tias txawm hais tias cov khoom lag luam nce siab thiab nce nqi tsim khoom, lub ntiaj teb hnub ci photovoltaic kev loj hlob xyoo no tseem xav tias yuav nce 17%.
Hauv ntau lub tebchaws thoob plaws ntiaj teb, cov phiaj xwm hluav taws xob hnub ci muab tus nqi qis tshaj ntawm cov hluav taws xob tshiab, tshwj xeeb tshaj yog nyob rau hauv cov nqi hluav taws xob nce ntxiv.IEA kwv yees tias xyoo 2021, 156.1GW ntawm kev teeb tsa photovoltaic yuav raug ntxiv thoob ntiaj teb.
Qhov no sawv cev rau cov ntaub ntawv tshiab.Txawm li cas los xij, daim duab no tseem qis dua lwm qhov kev txhim kho thiab kev cia siab rau kev teeb tsa.Lub koom haum tshawb fawb BloombergNEF kwv yees tias 191GW ntawm lub hnub ci zog tshiab yuav raug teeb tsa rau xyoo no.
Hauv qhov sib piv, IHS Market qhov kev npaj hnub ci teeb tsa lub peev xwm hauv 2021 yog 171GW.Qhov nruab nrab txoj kev loj hlob tau npaj los ntawm lub koom haum kev lag luam SolarPower Europe yog 163.2GW.
IEA tau hais tias COP26 lub rooj sib tham txog kev hloov pauv huab cua tau tshaj tawm lub hom phiaj ntawm lub zog huv dua.Nrog rau kev txhawb nqa muaj zog ntawm tsoomfwv cov cai thiab lub hom phiaj ntawm lub zog huv, hnub ci photovoltaic "tseem yog lub hauv paus ntawm kev siv hluav taws xob txuas ntxiv dua tshiab."
Raws li tsab ntawv ceeb toom, los ntawm 2026, lub zog tauj dua tshiab yuav suav txog ze li 95% ntawm lub ntiaj teb lub zog muaj peev xwm nce, thiab hnub ci photovoltaic ib leeg yuav suav ntau dua ib nrab.Tag nrho cov teeb tsa photovoltaic peev xwm yuav nce los ntawm kwv yees li 894GW xyoo no mus rau 1.826TW xyoo 2026.
Raws li lub hom phiaj ntawm kev txhim kho nrawm, lub ntiaj teb hnub ci photovoltaic txhua xyoo lub peev xwm tshiab yuav loj hlob ntxiv, mus txog ze li ntawm 260 GW los ntawm 2026. Cov lag luam tseem ceeb xws li Tuam Tshoj, Europe, Tebchaws Asmeskas, thiab Is Nrias teb muaj cov nqi loj tshaj plaws, thaum cov lag luam tawm tshiab xws li sub-Saharan Africa thiab Middle East kuj qhia txog kev loj hlob muaj peev xwm.
Fatih Birol, Tus Thawj Coj ntawm IEA, tau hais tias xyoo no qhov kev nce ntxiv ntawm lub zog tauj dua tshiab tau teeb tsa cov ntaub ntawv, uas qhia tau tias lwm qhov cim tau tshwm sim hauv kev lag luam hluav taws xob thoob ntiaj teb tshiab.
"Cov khoom lag luam siab thiab cov nqi hluav taws xob peb pom niaj hnub no ua rau muaj teeb meem tshiab rau kev lag luam hluav taws xob tauj dua tshiab, tab sis kev nce nqi ntawm fossil fuels kuj ua rau lub zog tauj dua tshiab dua."
IEA kuj tau tshaj tawm cov phiaj xwm kev loj hlob sai.Cov tswv yim no xav tias tsoomfwv tau daws cov teeb meem ntawm kev tso cai, kev sib koom ua ke ntawm kab sib chaws, thiab tsis muaj nyiaj them rov qab, thiab muab cov phiaj xwm kev txhawb nqa rau kev hloov pauv.Raws li txoj kev npaj no, 177.5GW ntawm hnub ci photovoltaic yuav raug xa mus thoob ntiaj teb xyoo no.
Txawm hais tias lub hnub ci hluav taws xob tau nce siab, cov phiaj xwm hluav taws xob txuas ntxiv tshiab tau xav tias yuav muaj tsawg dua li tus lej xav tau kom ua tiav lub ntiaj teb net-zero emission lub hom phiaj los ntawm nruab nrab ntawm lub xyoo pua no.Raws li lub hom phiaj no, nyob nruab nrab ntawm 2021 thiab 2026, qhov nruab nrab ntawm kev loj hlob ntawm cov hluav taws xob hluav taws xob tauj dua tshiab yuav luag ob npaug ntawm qhov xwm txheej tseem ceeb tau piav qhia hauv tsab ntawv ceeb toom.
Daim ntawv tshaj tawm tseem ceeb ntawm World Energy Outlook tso tawm los ntawm IEA thaum Lub Kaum Hli qhia tau hais tias hauv IEA's 2050 net xoom emission roadmap, lub ntiaj teb qhov nruab nrab txhua xyoo nce hauv hnub ci photovoltaics ntawm 2020 txog 2030 yuav ncav cuag 422GW.
Tus nqi nce ntawm silicon, steel, aluminium, thiab tooj liab yog qhov tsis zoo rau cov khoom muag
IEA tau hais nyob rau hauv tsab ntawv tshaj tawm tshiab uas tam sim no, nce nqi khoom muag tau ua rau muaj kev kub ntxhov siab rau cov nqi peev.Cov khoom siv ntawm cov khoom siv raw thiab nce nqi hluav taws xob hauv qee lub khw tau ntxiv cov kev sib tw ntxiv rau cov tuam txhab hnub ci photovoltaic nyob rau lub sijhawm luv.
Txij li thaum pib ntawm 2020, tus nqi ntawm photovoltaic-qib polysilicon muaj ntau tshaj plaub npaug, hlau tau nce 50%, txhuas tau nce 80%, thiab tooj liab tau nce 60%.Tsis tas li ntawd, tus nqi thauj khoom los ntawm Tuam Tshoj mus rau Tebchaws Europe thiab North America kuj tau nce siab, qee zaum los ntawm kaum npaug.
IEA kwv yees tias cov khoom muag thiab cov nqi thauj khoom yog kwv yees li 15% ntawm tag nrho cov nqi hluav taws xob hnub ci photovoltaic peev.Raws li kev sib piv ntawm cov khoom muag nruab nrab ntawm 2019 txog 2021, tag nrho cov peev txheej ntawm cov khoom siv hluav taws xob photovoltaic tuaj yeem nce li ntawm 25%.
Kev nce hauv cov khoom muag thiab kev thauj khoom tau cuam tshuam rau cov nqi cog lus ntawm tsoomfwv kev sib tw, thiab kev lag luam xws li Spain thiab Is Nrias teb tau pom cov nqi cog lus ntau dua xyoo no.IEA tau hais tias kev nce nqi ntawm cov cuab yeej xav tau rau cov chaw tsim hluav taws xob photovoltaic ua rau muaj kev sib tw rau cov neeg tsim khoom uas tau yeej qhov kev sib tw thiab cia siab tias yuav poob qis hauv cov nqi module.
Raws li IEA, los ntawm 2019 txog 2021, kwv yees li 100GW ntawm hnub ci photovoltaic thiab cua zog cov haujlwm uas tau yeej qhov kev sib tw tab sis tseem tsis tau muab tso rau hauv kev ua haujlwm tau ntsib qhov kev pheej hmoo ntawm cov khoom lag luam poob siab, uas tuaj yeem ncua lub sijhawm ua haujlwm.
Txawm li cas los xij, qhov cuam tshuam ntawm kev nce nqi ntawm cov khoom muag ntawm qhov kev thov rau lub peev xwm tshiab yog txwv.Tsoom fwv tsis tau txais kev hloov pauv txoj cai tseem ceeb los tshem tawm cov kev sib tw, thiab kev yuav khoom lag luam tau ua txhaum lwm cov ntaub ntawv xyoo-rau-xyoo.
Txawm hais tias muaj kev pheej hmoo ntawm cov khoom lag luam mus sij hawm ntev, IEA tau hais tias yog cov khoom lag luam thiab cov nqi thauj khoom yooj yim nyob rau yav tom ntej, kev poob qis hauv cov nqi ntawm hnub ci photovoltaic yuav txuas ntxiv mus, thiab kev cuam tshuam mus ntev rau qhov kev thov thev naus laus zis no. tej zaum nws kuj yuav tsawg heev.
