Tus nqi ntawm cov khoom siv hnub ci tau nqis los ntawm 89% txij li xyoo 2010. Nws puas tseem pheej yig dua?
Yog tias koj txaus siab rau lub hnub ci thiab lub zog tauj dua tshiab, tej zaum koj yuav paub tias cov nqi cua thiab hnub ci thev naus laus zis tau poob qis tsis txaus ntseeg nyob rau xyoo tas los no.
Muaj ob peb lo lus nug uas cov tswv tsev uas xav txog kev mus hnub ci feem ntau muaj.Thawj yog: Lub hnub ci fais fab puas pheej yig dua?Thiab lwm yam yog: Yog tias hnub ci tau pheej yig dua, kuv puas yuav tsum tos ua ntej txhim kho lub hnub ci ntawm kuv lub tsev?
Tus nqi ntawm lub hnub ci vaj huam sib luag, inverter, thiab lithium roj teeb tau txais pheej yig dua hauv 10 xyoo dhau los.Cov nqi yuav tsum tau nce mus ntxiv - qhov tseeb, hnub ci tau kwv yees kom tsis tu ncua ntawm tus nqi mus txog xyoo 2050.
Txawm li cas los xij, tus nqi ntawm lub hnub ci kev teeb tsa yuav tsis poob ntawm tib tus nqi vim tias cov nqi kho vajtse tsawg dua 40% ntawm tus nqi tag rau lub tsev hnub ci teeb.Tsis txhob cia siab tias lub hnub ci hauv tsev yuav pheej yig dua yav tom ntej.Qhov tseeb, koj cov nqi yuav nce ntxiv raws li cov nyiaj rov qab hauv zos thiab tsoomfwv tau tas sijhawm.
Yog tias koj tab tom xav txog kev ntxiv hnub ci rau koj lub tsev, tos tej zaum yuav tsis txuag koj nyiaj.Nruab koj lub hnub ci vaj huam sib luag tam sim no, tshwj xeeb tshaj yog vim cov qhab nia them se tas sij hawm.
Nws raug nqi npaum li cas rau nruab hnub ci vaj huam sib luag rau hauv tsev?
Muaj ntau ntau yam uas nkag mus rau hauv tus nqi ntawm lub tsev solar vaj huam sib luag, thiab ntau txoj kev xaiv koj tuaj yeem ua qhov ntawd cuam tshuam rau tus nqi kawg uas koj them.Txawm li cas los xij, nws tseem ceeb heev kom paub tias kev lag luam tiam sis yog dab tsi.
Tus nqi piv rau 20 lossis 10 xyoo dhau los yog qhov zoo siab, tab sis tsis ntev los no tus nqi poob qis tsis ze li qhov txaus ntshai.Qhov no txhais tau hais tias koj tuaj yeem cia siab tias tus nqi hnub ci yuav poob mus ntxiv, tab sis tsis txhob cia siab tias yuav txuag tau nyiaj ntau.
Tus nqi hnub ci zog poob npaum li cas?
Tus nqi ntawm cov hnub ci vaj huam sib luag tau nqis los ntawm qhov tsis txaus ntseeg.Rov qab rau xyoo 1977, tus nqi ntawm lub hnub ci photovoltaic yog $ 77 rau ib lub watt ntawm lub zog xwb.Hnub no?Koj tuaj yeem pom cov hnub ci hnub ci nqi qis li $ 0.13 ib watt, lossis kwv yees li 600 npaug tsawg dua.Tus nqi feem ntau tau ua raws li Swanson Txoj Cai Lij Choj, uas tau hais tias tus nqi hnub ci poob los ntawm 20% rau txhua ob npaug ntawm cov khoom xa tuaj.
Qhov kev sib raug zoo ntawm kev tsim khoom ntim thiab tus nqi yog qhov tseem ceeb, vim tias raws li koj yuav pom, tag nrho kev lag luam thoob ntiaj teb tau hloov pauv mus rau lub zog tauj dua tshiab.
20 xyoo dhau los yog lub sijhawm ntawm kev loj hlob zoo kawg rau kev faib hnub ci.Kev faib tawm hnub ci yog hais txog cov tshuab me me uas tsis yog ib feem ntawm cov khoom siv hluav taws xob siv hluav taws xob - hauv lwm lo lus, lub ru tsev thiab sab nraum zoov hauv tsev thiab kev lag luam thoob plaws hauv lub tebchaws.
Muaj kev lag luam me me hauv xyoo 2010, thiab nws tau tawg hauv xyoo txij li.Thaum muaj kev poob qis hauv 2017, txoj kev loj hlob nkhaus hauv 2018 thiab thaum ntxov 2019 tau nce mus ntxiv.
Swanson Txoj Cai piav qhia txog qhov kev loj hlob loj no tseem ua rau tus nqi poob qis: hnub ci module nqi tau nqis los ntawm 89% txij li xyoo 2010.
Cov nqi kho vajtse piv rau cov nqi muag muag
Thaum koj xav txog lub hnub ci, tej zaum koj yuav xav tias nws yog cov khoom siv uas ua rau feem ntau ntawm cov nqi: cov racking, thaiv, inverters, thiab cov hnub ci vaj huam sib luag lawv tus kheej.
Qhov tseeb, kho vajtse tso nyiaj tsuas yog 36% ntawm tus nqi ntawm lub hnub ci hauv tsev.Tus so yog coj los ntawm cov nqi muag muag, uas yog lwm cov nuj nqis uas lub hnub ci installer yuav tsum dais.Cov no suav nrog txhua yam los ntawm kev teeb tsa kev ua haujlwm thiab kev tso cai, mus rau cov neeg tau txais (piv txwv li kev muag khoom thiab kev lag luam), mus rau cov nyiaj siv ua haujlwm dav dav (piv txwv li khaws lub teeb rau).
Koj tseem yuav pom tias cov nqi muag muag dhau los ua qhov feem pua ntawm cov nqi qis dua vim tias qhov system loj tuaj.Qhov no yog qhov tseeb tshwj xeeb tshaj yog thaum koj mus los ntawm cov chaw nyob mus rau qhov chaw siv hluav taws xob, tab sis cov tsev nyob loj feem ntau kuj muaj tus nqi qis-ib-watt dua li cov tshuab me.Qhov no yog vim muaj ntau tus nqi, xws li kev tso cai thiab kev yuav cov neeg siv khoom, raug kho thiab tsis sib txawv ntau (lossis tag nrho) nrog rau qhov system loj.
Hnub ci yuav loj hlob thoob ntiaj teb li cas?
Tebchaws Asmeskas tsis yog lub khw loj tshaj plaws hauv ntiaj teb rau hnub ci.Tuam Tshoj tau tshaj US los ntawm qhov deb, txhim kho hnub ci ntawm kwv yees li ob npaug ntawm tus nqi ntawm Teb Chaws Asmeskas.Tuam Tshoj, zoo li feem ntau lub xeev Asmeskas, muaj lub hom phiaj siv hluav taws xob txuas ntxiv mus.Lawv tab tom tsom rau 20% lub zog tauj dua tshiab los ntawm 2030. Qhov ntawd yog qhov kev hloov pauv loj rau lub tebchaws uas siv cov thee los ua kom muaj zog ntau ntawm nws txoj kev loj hlob.
Txog xyoo 2050, 69% ntawm lub ntiaj teb hluav taws xob yuav rov ua dua tshiab.
Xyoo 2019, lub hnub ci fais fab tsuas yog 2% ntawm lub ntiaj teb lub zog, tab sis nws yuav loj hlob mus rau 22% los ntawm 2050.
Cov roj teeb loj loj, daim phiaj-scale yuav yog qhov tseem ceeb rau kev loj hlob no.Cov roj teeb yuav yog 64% pheej yig dua los ntawm 2040, thiab lub ntiaj teb yuav tau teeb tsa 359 GW ntawm roj teeb los ntawm 2050.
Cov nyiaj tau los ntawm hnub ci kev nqis peev yuav ntaus $ 4.2 trillion los ntawm 2050.
Nyob rau tib lub sijhawm, kev siv thee yuav poob los ntawm ib nrab ntawm lub ntiaj teb, nqis mus rau 12% ntawm tag nrho cov khoom siv hluav taws xob.
Cov nqi nruab hnub ci vaj tsev nyob tau tso tseg, tab sis tib neeg tau txais cov cuab yeej zoo dua
Daim ntawv tshaj tawm tshiab tshaj plaws los ntawm Berkeley Lab qhia tau hais tias tus nqi teeb tsa ntawm lub hnub ci vaj tsev nyob tau ua rau ob peb xyoos dhau los.Qhov tseeb, hauv 2019, tus nqi nruab nrab tau nce li ntawm $ 0.10.
Ntawm lub ntsej muag ntawm nws, qhov ntawd yuav ua rau nws zoo li hnub ci tau pib tau txais kim dua.Nws tsis muaj: cov nqi txuas ntxiv poob txhua xyoo.Qhov tseeb, qhov tshwm sim yog tias cov neeg siv khoom hauv tsev tau txhim kho cov cuab yeej zoo dua, thiab tau txais txiaj ntsig ntau dua rau tib cov nyiaj.
Piv txwv li, xyoo 2018, 74% ntawm cov neeg siv khoom nyob hauv tsev xaiv micro inverters los yog lub hwj chim optimizer-raws li inverter tshuab dua cov hlua hluav taws xob tsawg dua.Hauv 2019, tus lej no tau dhia mus rau 87%.
Ib yam li ntawd, xyoo 2018, cov tswv tsev nruab nrab hnub ci tau nruab hnub ci vaj huam sib luag nrog 18.8% kev ua haujlwm, tab sis xyoo 2019 qhov ua tau zoo tau nce mus rau 19.4%.
Yog li thaum daim ntawv them nqi cov tswv tsev them rau hnub ci hnub no yog tiaj tus lossis txawm nce me ntsis, lawv tau txais cov cuab yeej zoo dua rau tib cov nyiaj.
