Ngapha koko, yeyiphi engcolisa kakhulu? Imoto yombane esebenzisa umbane oveliswa ngokutshiswa kwamafutha efosili okanye imoto yepetroli? Lo mbuzo uye waba yingxabano phakathi kwabalandeli beemoto zombane kunye nabaxhasi beenjini zokutsha, kodwa ngoku kukho impendulo.
Ngokophononongo olupapashwe yiBloomberg, imoto yombane okwangoku ikhupha i-avareji ye-40% ngaphantsi kwe-CO2 kune-petroli-powered one . Nangona kunjalo, lo mahluko uyahluka ngokwelizwe esithetha ngalo.
Ke, isifundo sinika umzekelo we-United Kingdom kunye neTshayina. E-UK, umahluko mkhulu kune-40%, yonke into ibonga ukusetyenziswa kwemithombo yamandla avuselelekayo. E-China, elilizwe apho iimoto ezininzi zombane zithengiswa khona, umahluko ungaphantsi kwe-40%, konke ngenxa yokuba amalahle asengomnye wemithombo ephambili yemveliso yombane.
Izinto ezikhutshwayo zasekuhlaleni vs ezikhutshwa kwiindawo ezikhutshwayo
Kolu balo abazange babale kuphela ukukhutshwa ngexesha lokusetyenziswa kwemoto, kodwa kunye nokukhutshwa okwenzeka ngexesha lemveliso. Kodwa ikwenza ucinge. Ingaba imoto yombane ingaba nayo njani i-CO2 ekhutshwayo xa siyiqhuba? Ewe, kulapho izinto ezikhutshwayo zalapha ekhaya kunye nezinto ezikhutshwayo ezifuduswayo zingena khona.

Xa siqhuba imoto nge-injini yokutsha yangaphakathi, inokukhutshwa kwendawo - oko kukuthi, abo baphuma ngqo kumbhobho wokukhupha -; umbane, nangona ungakhuphi i-CO2 xa isetyenzisiwe - ayitshisi i-fuel, ngoko ke akukho kukhutshwa kwanoma yiluphi uhlobo - inokukhupha iigesi ezingcolisayo ngokungangqalanga, xa siqwalasela imvelaphi yombane ofunekayo.
Ukuba umbane owusebenzisayo uveliswa kusetyenziswa amafutha efosili, iziko lombane kuya kufuneka likhuphe iCO2. Yiyo loo nto umahluko phakathi kwezi ntlobo zimbini zeenjini okwangoku ukwi-40% kuphela.
UColin McKerracher, umhlalutyi wezoThutho kwi-BNEFXa isithuthi sokutsha sangaphakathi sishiya umgca wendibano, ukukhutshwa kwayo nge-km sele kuchaziwe, kwimeko yeetram ezi ziwela unyaka nonyaka njengoko imithombo yamandla ihlambuluka.
Ngokutsho kwabaphandi, umkhwa kukuba umsantsa ukhule, njengoko amazwe afana neTshayina eqala ukwamkela imithombo yamandla avuselelekayo. Nangona kunjalo, nangona umbane uvela kumalahle avuthayo, iimoto zombane sele zikwazi ukungcolisa ngaphantsi kunezilinganisi zazo zepetroli.
Ngokutsho kophando lweBloombergNEF, uphuhliso lwetekhnoloji luya kunceda ukunciphisa ukukhutshwa kweenjini zokutsha nge-1.9% ngonyaka ngo-2040, kodwa kwimeko yeenjini zombane, siyabonga, ngaphezu kwakho konke, ukwamkelwa kwemithombo yamandla avuselelekayo, oku kuphuka kulindeleke ukuba kube phakathi. 3% kunye ne-10% ngonyaka.
