Ntawm ib lub teb chaws, Tebchaws Asmeskas thiab Canada vam khom qhov sib txawv ntawm qhov chaw los tsim lawv cov hluav taws xob.
Tebchaws Asmeskas feem ntau siv cov pa roj carbon monoxide, thee, thiab nuclear fais fab, thaum Canada cia siab rau ob qho tib si hydro thiab nuclear. Uas tau hais tias, thaum zoom rau hauv lub xeev lossis xeev, ib tus neeg thawj qhov chaw hluav taws xob tuaj yeem sib txawv heev.
Nyob rau hauv infographic hauv qab no, Visual Capitalist's Selin O?uz coj mus saib cov kev tsim hluav taws xob nyob rau hauv lub xeev thiab cov xeev ntawm ob lub teb chaws no siv cov ntaub ntawv los ntawm cov Lub Koom Haum Txuag Hluav Taws Xob (2021) thiab Canada Energy Regulator (2019).
Nkev
Natural roj yog dav siv rau kev tsim hluav taws xob hauv Tebchaws Meskas. Paub tias yog "ntxuav" fossil roj, nws cov nplua nuj, ua ke nrog kev tsim lub teb chaws kev faib tawm thiab tus nqi qis, ua rau nws yog qhov tseem ceeb tshaj plaws hauv lub tebchaws.
Nyob rau hauv 2021, 38% ntawm cov 4120 terawatt-teev (TWh) hluav taws xob tsim nyob rau hauv Teb Chaws Asmeskas yog los ntawm natural gas. Tsis yog qhov xav tsis thoob, ntau dua 40% ntawm cov xeev Asmeskas muaj cov pa roj carbon monoxide ua lawv qhov hluav taws xob loj tshaj plaws.
Nov yog qee lub xeev uas muaj feem loj tshaj plaws ntawm cov khoom siv hluav taws xob los ntawm hluav taws xob.
Hauv Canada, cov pa roj ntsha tsuas yog qhov thib peb loj tshaj plaws hluav taws xob (tom qab hydro thiab nuclear), suav nrog 11% of the 632 TWh ntawm cov hluav taws xob tsim tawm xyoo 2019. Alberta yog tib lub xeev uas muaj cov pa roj carbon monoxide ua nws qhov tseem ceeb ntawm hluav taws xob.
Nuclear
Nuclear zog yog lub zog tsis muaj cov pa roj carbon monoxide uas ua rau muaj feem ntau ntawm lub zog tsim tawm hauv Asmeskas thiab Canada.
19% ntawm Asmeskas thiab 15% ntawm Canada hluav taws xob los ntawm nuclear fais fab. Thaum cov feem pua nyob ze rau ib leeg, nws yog qhov zoo uas yuav tsum nco ntsoov tias Tebchaws Meskas tsim hluav taws xob 6 mus rau 7 npaug ntau dua li Canada txhua xyoo, ua rau muaj zog nuclear ntau dua li Canada raws li gigawatt teev (GWh) ib xyoos twg.

Raws li pom nyob rau hauv daim ntawv qhia, ntau lub xeev thiab cov xeev nrog nuclear raws li lawv lub ntsiab ntawm hluav taws xob yog concentrated nyob rau hauv sab hnub tuaj ib nrab ntawm ob lub teb chaws.
Hauv Asmeskas, Illinois, Pennsylvania, thiab South Carolina yog cov neeg tsim khoom loj tshaj plaws ntawm GWh / xyoo. Illinois thiab South Carolina tseem muaj nuclear ua lawv qhov tseem ceeb hluav taws xob, qhov chaw Pennsylvania cov hluav taws xob tsim tawm los ntawm cov nkev roj ntau tshaj li ntawm nuclear.
Feem coob ntawm Canada lub nuclear reactors (18 ntawm 19) yog nyob rau hauv Ontario, nrog rau 19th nyob rau hauv New Brunswick. Ob lub xeev no tso siab rau nuclear ua lawv qhov loj tshaj plaws ntawm hluav taws xob.
Renewables: Hydro, Cua thiab Hnub Ci
Tawm ntawm qhov sib txawv ntawm cov khoom siv hluav taws xob tauj dua tshiab, hydro yog qhov nthuav dav tshaj plaws hauv North America. Piv txwv li, 60% ntawm Canada thiab 6% ntawm Teb Chaws Asmeskas hluav taws xob los ntawm hydropower.
Ntawm no yog cov xeev thiab cov xeev uas muaj hydro ua lawv qhov loj tshaj plaws ntawm hluav taws xob.
Cua thiab hnub ci zog ua ke suav nrog ib feem me me ntawm tag nrho cov hluav taws xob tsim nyob rau hauv ob lub teb chaws. Txawm hais tias tsis muaj lub xeev lossis lub xeev tso siab rau hnub ci raws li nws qhov loj tshaj plaws ntawm hluav taws xob, Iowa, Kansas, Oklahoma, thiab South Dakota cia siab rau cua rau lawv cov hluav taws xob, nrog rau Canada tus tub huabtais Edward Island (PEI).
Coal thiab Roj
Cov thee thiab roj yog cov khoom siv hluav taws xob hnyav uas tseem muaj nyob hauv North America.
Tam sim no, 22% ntawm Asmeskas thiab 7% ntawm Canada cov hluav taws xob los ntawm cov thee, nrog rau cov chaw xws li Kentucky, Missouri, West Virginia, Saskatchewan, thiab Nova Scotia tseem cia siab rau cov thee ua lawv qhov loj tshaj plaws ntawm hluav taws xob.
Qee thaj chaw kuj siv roj av los tsim lawv cov hluav taws xob. Txawm hais tias nws siv rau lub hom phiaj no poob qis, nws tseem yog qhov loj tshaj plaws ntawm hluav taws xob hauv Hawaii thiab Nunavut.
Nyob rau hauv ob peb xyoos tom ntej no, nws yuav txaus siab los soj ntsuam kev siv cov fossil fuels rau kev tsim hluav taws xob hauv Asmeskas thiab Canada. Txawm tias qhov sib txawv hauv huab cua cog lus nruab nrab ntawm ob lub teb chaws, kev txo qis cov pa roj carbon monoxide thiab cov roj emissions tuaj yeem yog ib feem tseem ceeb ntawm kev ntaus cov hom phiaj decarbonization raws sijhawm.
