Hydroelectric zog yog qhov pheej yig tshaj qhov chaw ntawm renewable zog , ntawm qhov nruab nrab ntawm $ 0.05 ib kilowatt teev (kWh), tab sis tus nqi nruab nrab ntawm kev tsim hluav taws xob tshiab raws li onshore cua, hnub ci photovoltaic (PV), biomass lossis geothermal zog Tam sim no feem ntau yog qis dua $ 0.10 / kWh.
Yog li ntawd, lub zog tauj dua tshiab puas pheej yig dua li lub zog tsis txuas ntxiv dua tshiab?
Kev tshawb fawb tshiab qhia tau hais tias, nyob rau lub sijhawm ntev, renewable zog yog tus nqi ntau dua tshaj tsis - renewable zog . Lub tuam txhab Lazard suav tias yog tus nqi tshaj li lub neej ntawm zog tej yaam num thiab pom cua thiab nqi hluav taws xob-teev hnub ci yuav yog qhov tsawg tshaj plaws zog tsim qhov chaw.
Tsis tas li ntawd, puas yog nuclear pheej yig dua li txuas ntxiv dua tshiab? Rov ua dua tshiab zog yog pheej yig dua thiab txo emissions sai dua tshaj nuclear zog, wg rau ntiaj teb Nuclear Kev Lag Luam Status Report los ntawm Fabkis tus kws pab tswv yim kev lag luam Mycle Schneider. Yog li cov nroj tsuag fossil-fueled uas twb muaj lawm tso tawm ntau dua CO2 thaum tos kev hloov pauv los ntawm nuclear kev xaiv.
Hauv qhov no, lub zog tauj dua tshiab puas pheej yig dua?
Bloomberg New Zog Nyiaj Txiag (BNEF) tau tshaj tawm hnub Tuesday tias rov ua dua tshiab yog tam sim no pheej yig tshaj daim ntawv ntawm kev tsim hluav taws xob tshiab thoob plaws ob feem peb ntawm lub ntiaj teb - pheej yig dua dua li ob qho tib si tshiab thee thiab tshiab natural gas zog.
Yuav ua li cas yog lwm lub npe rau lub zog tauj dua tshiab?
Lawv yeej tsis tuaj yeem depleted. Qee qhov piv txwv ntawm renewable zog qhov chaw yog hnub ci zog , zog zog , hydropower, geothermal zog , thiab biomass zog . Cov hom no lub zog txawv ntawm fossil fuels, xws li thee, roj, thiab natural gas.

Dab tsi yog qhov tsis zoo ntawm kev siv cov khoom siv hluav taws xob txuas ntxiv dua tshiab?
Ib qho ntawm qhov tsis zoo ntawm lub zog tsis txuas ntxiv yog tias nws siv sijhawm ntev. Mining ntawm cov thee, nrhiav cov roj, txhim kho cov roj xyaum, tsim cov roj rigs, ntxig cov kav dej kom tshem tawm thiab kev thauj mus los ntawm cov roj av yog cov txheej txheem siv sijhawm ntau. Lawv kuj siv zog ntau heev
Dab tsi yog kev siv hluav taws xob Yuav ua li cas kev lag luam tsim ntau hom kev siv hluav taws xob?
Kev siv hluav taws xob yog hais txog tus nqi lossis txiaj ntsig uas tus neeg siv khoom tau txais los ntawm kev sib pauv, raws li University of Delaware. Muaj plaub hom kev siv: daim ntawv, qhov chaw, sijhawm thiab muaj; ua ke, lawv pab tsim cov neeg siv khoom txaus siab
Dab tsi yog qhov zoo ntawm cov khoom siv hluav taws xob tauj dua tshiab?
Qhov zoo ntawm lub zog tauj dua tshiab Renewable zog yuav tsis tag. Kev tu vaj tse yog qis dua. Renewables txuag nyiaj. Lub zog tauj dua tshiab muaj ntau yam kev noj qab haus huv thiab ib puag ncig. Renewables txo kev cia siab rau cov khoom siv hluav taws xob txawv teb chaws. Tus nqi siab dua. Intermittency. Muaj peev xwm khaws cia
Dab tsi yog lub ntiaj teb kev siv hluav taws xob tauj dua tshiab uas siv los tsim hluav taws xob?
Hydropower
Dab tsi yog qhov sib txawv tseem ceeb ntawm cov khoom siv hluav taws xob tauj dua tshiab thiab cov fossil fuels?
Fossil Roj. Fossil fuels (coal, roj thiab natural gas) tseem yog qhov tseem ceeb rau kev thauj mus los, tsim hluav taws xob, cua sov, cog kev ua haujlwm, thiab lwm yam. Tab sis lawv kuj yog lub hauv paus tseem ceeb ntawm CO2 emissions thiab, tsis zoo li lub zog tauj dua tshiab, yog tsim los ntawm cov khoom siv tag - txawm tias tseem loj heev - khaws cia
