Texas coj Asmeskas hauv kev teeb tsa cua, nrog 30.46 GW, thiab nws yog qhov thib ob hauv hnub ci zog, nrog 8.6 GW raws li lub Yim Hli. Cov peev txheej no tau muab cov txiaj ntsig tseem ceeb nyiaj txiag thiab kev noj qab haus huv, raws li kev tshawb fawb los ntawm Joshua Rhodes, tus thawj coj thev naus laus zis ntawm IdeaSmiths, lub tuam txhab tshuaj xyuas lub zog nyob hauv Austin, Texas.
Sandie Haverlah, tus thawj tswj hwm ntawm Texas Consumer Association, tau hais tias "Texas xav tau ob npaug ntawm cov txiaj ntsig no, nce cov neeg siv khoom txuag nyiaj los ntawm kev nce hnub ci thiab cua," Sandie Haverlah, tus thawj tswj hwm ntawm Texas Consumer Association, tau hais hauv tsab ntawv tshaj tawm Lub Kaum Hli 18.
Daim ntawv tshaj tawm sib piv qhov kev ua tau zoo ntawm ERCOT kev lag luam nrog nws yuav ua li cas rho tawm cov hnub ci thiab cua.

Renewables "tau txo cov nqi hluav taws xob hauv khw muag khoom nyob rau nruab nrab ntawm $ 1.17 / MWh (hauv xyoo 2012) thiab $ 20.60 / MWh (hauv 2022) los ntawm kev them nqi hluav taws xob kim dua," raws li tsab ntawv ceeb toom.
Kev nce rau cov neeg siv khoom siv hnab tshos tau loj dua xyoo no vim tias muaj cua daj cua dub thiab hnub ci ntau ntxiv nrog rau cov pa roj carbon monoxide thiab cov nqi hluav taws xob uas tau ntau dua li cov xyoo dhau los, nws hais.
Xyoo no, roj nqi nruab nrab yog $ 6.24 ib lab British thermal units, piv nrog $ 3.64 ib MMBtu xyoo tas los. Cov nqi hluav taws xob tau nce hauv 2022 txog $ 3.72 / MMBtu piv nrog rau xyoo tas los tus nqi ntawm $ 3.26 MMBtu. Daim ntawv tshaj tawm sau tseg tias thermal fais fab nroj tsuag marginal nqi sib txawv nyob ntawm seb lawv cov yam ntxwv tshwj xeeb.
Ntxiv nrog rau qhov kev dhia hauv cov nqi hluav taws xob thiab cov nqi hluav taws xob, Lone Star State muaj lub caij ntuj sov kub heev, tsav tsheb kom xav tau thiab nce tus nqi ntawm cov phiaj xwm txuas ntxiv dua tshiab.
Cov hluav taws xob tauj dua tshiab tau txo cov pa phem, tshwj xeeb tshaj yog nyob rau hauv cov zej zog ntom ntom, overburdened, los ntawm kev hloov cov fossil-fueled tiam, daim ntawv tshaj tawm hais tias. Cov peev txheej sib cuam tshuam tau pom tias tau zam 416, 000 tons ntawm SO2, 318, 000 tons ntawm NOx, thiab 558 lab tons ntawm CO2 emissions txij li xyoo 2010.
Rau cov zej zog muaj kev cuam tshuam loj heev, Rhodes muaj nuj nqis rau kev zam SOx emissions mus txog $ 107,000 ib tuj thiab NOx emissions ntawm $12,000 ib tuj vim tsawg dua tsev kho mob ntawm cov neeg mob uas muaj kev cuam tshuam ua pa. Daim ntawv tshaj tawm muab qhov nruab nrab emission tus nqi rau SOx ntawm $ 16,600 / ton, NOx ntawm $ 4,750 / ton thiab CO2 ntawm $ 20 / ton.
Kev poob qis hauv emissions tau cawm Texans ntawm $ 10.2 billion thiab $ 76.4 nphom hauv kev kho mob thiab lwm yam kev cuam tshuam ib puag ncig, daim ntawv tshaj tawm tau hais.
Tsis zoo li cov fossil-roj tsim, cov peev txheej txuas ntxiv txuas ntxiv tsis tu ncua tsis siv cov dej tshiab rau lub tshuab hluav taws xob txias, Rhodes tau hais. Lub hnub ci thiab cua qhov chaw tau zam kev siv "244 billion nkas loos ntawm lub zog dej los ntawm 2010 txog Lub Yim Hli 2022, uas yuav tau ntxiv kev ntxhov siab rau cov cheeb tsam uas feem ntau muaj dej nag," tsab ntawv ceeb toom hais. Rhodes kwv yees cov nyiaj khaws cia li ntawm $ 0.7 billion thiab $ 1.7 billion.
