Kev sib xyaw hluav taws xob ntawm Bitcoin (BTC) tau hloov pauv ntau dhau los ob peb xyoos dhau los, nrog rau lub zog nuclear thiab cov nkev nkev tau dhau los ua qhov loj hlob sai tshaj plaws ntawm lub zog siv zog Bitcoin mining, raws li cov ntaub ntawv tshiab.
Cambridge Center for Alternative Finance (CCAF) rau hnub Tuesday tau tshaj tawm qhov hloov tshiab loj rau nws cov ntaub ntawv Bitcoin mining-dedicated qhov chaw, Cambridge Bitcoin Electricity Consumption Index (CBECI).
Raws li cov ntaub ntawv los ntawm Cambridge, fossil fuels xws li thee thiab natural gas ua tau yuav luag ob feem peb ntawm Bitcoin tag nrho cov hluav taws xob sib xyaw thaum Lub Ib Hlis 2022, suav txog ntau dua 62%. Raws li xws li, qhov sib koom ntawm cov khoom siv hluav taws xob ruaj khov hauv BTC lub zog sib xyaw yog 38%.
Txoj kev tshawb fawb tshiab qhia tias cov thee ib leeg suav txog ze li 37% ntawm Bitcoin tag nrho cov hluav taws xob siv thaum ntxov 2022, dhau los ua qhov loj tshaj plaws ntawm lub zog rau BTC mining. Ntawm cov khoom siv hluav taws xob ruaj khov, hydropower tau pom tias yog cov peev txheej loj tshaj plaws, nrog rau kwv yees li 15%.
Txawm hais tias Bitcoin mining vam khom rau cov thee thiab hydropower, qhov sib koom ntawm cov khoom siv hluav taws xob hauv tag nrho BTC lub zog sib xyaw tau poob rau ntau xyoo dhau los. Nyob rau hauv 2020, thee fais fab mov powered 40% ntawm lub ntiaj teb no BTC mining. Kev faib tawm ntawm Hydropower tau ntau dua li ib nrab ntawm 2020 txog 2021, poob ntawm 34% mus rau 15%.
Nyob rau hauv sib piv, lub luag hauj lwm ntawm natural gas thiab nuclear zog nyob rau hauv Bitcoin mining tau loj hlob notably nyob rau hauv ob lub xyoos dhau los. Qhov sib faib ntawm cov roj hauv BTC hluav taws xob sib xyaw tau nce los ntawm kwv yees li 13% hauv 2020 txog 23% hauv 2021, thaum feem pua ntawm cov hluav taws xob nuclear tau nce los ntawm 4% hauv 2021 txog ze li 9% hauv 2022.
Raws li Cambridge cov kws tshuaj ntsuam, Suav cov miner tsiv chaw yog qhov laj thawj tseem ceeb tom qab qhov kev hloov pauv ntawm Bitcoin lub zog sib xyaw hauv 2020 thiab 2021. Tuam Tshoj txoj kev tawg ntawm crypto hauv 2021 thiab kev cuam tshuam cov miner tsiv teb tsaws tau ua rau poob loj hauv kev sib koom ntawm hydroelectric zog hauv BTC zog. sib tov. Raws li yav dhau los tau tshaj tawm, Suav tub ceev xwm kaw ib tug xov tooj ntawm crypto mining ua liaj ua teb powered by hydroelectricity hauv 2021.
"Tsoomfwv Suav tau txwv tsis pub cryptocurrency mining thiab ua rau muaj kev hloov pauv hauv Bitcoin mining kev ua rau lwm lub tebchaws cuam tshuam rau Bitcoin ib puag ncig hneev taw," txoj kev tshawb fawb qhia.
Cov kws tshuaj ntsuam kuj tseem hais ntxiv tias BTC hluav taws xob sib xyaw sib txawv loj heev, nyob ntawm thaj tsam. Lub teb chaws zoo li Kazakhstan tseem vam khom rau cov roj fossil, thaum nyob hauv cov tebchaws xws li Sweden, qhov sib koom ntawm cov khoom siv hluav taws xob ruaj khov hauv kev tsim hluav taws xob yog li 98%.
Kev nce siab ntawm lub zog ntawm nuclear thiab roj hauv Bitcoin qhov hluav taws xob sib xyaw ua rau muaj kev cuam tshuam txog "kev hloov pauv ntawm lub zog mining mus rau Tebchaws Meskas," cov kws tshuaj ntsuam tau hais. Raws li US Energy Information Administration, feem ntau ntawm lub teb chaws hluav taws xob yog generated los ntawm cov roj av, uas suav txog ntau dua 38% ntawm lub teb chaws cov khoom siv hluav taws xob tag nrho. Coal thiab nuclear zog suav txog 22% thiab 19%, feem.
Ntawm lwm qhov kev nkag siab hais txog qhov hloov tshiab CBECI tshiab, txoj kev tshawb fawb kuj pom tias cov pa hluav taws xob hauv tsev cog khoom (GHG) cuam tshuam nrog BTC mining suav txog 48 lab metric tons ntawm carbon dioxide sib npaug (MtCO2e) txij li lub Cuaj Hlis 21, 2022. Qhov ntawd yog 14%. qis dua qhov kwv yees GHG emissions hauv 2021. Raws li kev tshawb fawb kwv yees, GHG emissions theem tam sim no cuam tshuam nrog Bitcoin sawv cev kwv yees li 0.1% ntawm ntiaj teb GHG emissions.
Ua ke tag nrho cov kev tshawb pom yav dhau los, qhov ntsuas tau kwv yees tias los ntawm nruab nrab Lub Cuaj Hli, txog 199.6 MtCO2e tuaj yeem raug ntaus nqi rau Bitcoin network txij li thaum nws pib. Cov kws tshuaj ntsuam tau hais tias kwv yees li 92% ntawm tag nrho cov emissions tau tshwm sim txij li xyoo 2018.
Raws li yav dhau los tau tshaj tawm, CCAF tau ua haujlwm ntawm CBECI ua ib feem ntawm nws txoj kev tshawb fawb ntau xyoo hu ua Cambridge Digital Assets Program (CDAP). CDAP cov koom haum koom tes suav nrog cov tuam txhab nyiaj txiag xws li British International Investment, Dubai International Finance Center, Accenture, EY, Fidelity, Mastercard, Visa thiab lwm yam.

Qhov kev tshawb pom tshiab CDAP txawv txawv ntawm cov ntaub ntawv los ntawm Bitcoin Mining Council (BMC), uas nyob rau lub Xya Hli tau kwv yees qhov sib faib ntawm cov peev txheej ruaj khov hauv Bitcoin hluav taws xob sib xyaw ntawm ze li 60%.
"Nws tsis suav nrog nuclear lossis fossil fuels yog li los ntawm qhov koj tuaj yeem txhais tau tias thaj tsam 30% -40% ntawm kev lag luam yog siv los ntawm fossil fuels," Bitfarms tus thawj coj mining Ben Gagnon hais rau Cointelegraph thaum Lub Yim Hli.
Raws li CBECI txoj haujlwm ua thawj coj Alexander Neumueller, CDAP txoj hauv kev yog txawv ntawm Bitcoin Mining Council thaum nws los txog rau kev kwv yees Bitcoin hluav taws xob sib xyaw.
"Peb siv cov ntaub ntawv los ntawm peb daim ntawv qhia mining kom pom qhov twg Bitcoin miners nyob, thiab tom qab ntawd tshuaj xyuas lub teb chaws, xeev, lossis xeev cov hluav taws xob sib xyaw. Raws li kuv nkag siab nws, Bitcoin Mining Council hais kom nws cov tswv cuab los qhia tus kheej cov ntaub ntawv no hauv kev soj ntsuam, "Neumueller tau hais. Nws tseem hais tias tseem muaj qee qhov nuances ntsig txog qhov tsis muaj ntaub ntawv hauv txoj kev tshawb fawb.
