I-injini yokuncedisa inqanawa idla ngokusetyenziselwa ukuvelisa amandla xa inqanawe imile ukuze ihlangabezane nemfuno yamandla enqanawe.Imfuno yamandla yeentlobo ezahlukeneyo zeenqanawa zahlukile.Ukongeza kwimfuno yamandla yasekhaya yabasebenzi, iinqanawa zeekhonteyina nazo kufuneka zinike amandla kwizikhongozeli ezifakwe efrijini;Inqanawa yemithwalo ngokubanzi nayo ifuna ukunika amandla kwi-crane ebhodini, ngoko ke kukho umahluko omkhulu womthwalo kwimfuno yobonelelo lwamandla eentlobo ngeentlobo zeenqanawa zokukhwela, kwaye ngamanye amaxesha kunokubakho imfuno enkulu yomthwalo wamandla.I-injini yokuncedisa yaselwandle iya kukhupha inani elikhulu lezinto ezingcolileyo kwinkqubo yokusebenza, ngokukodwa kuquka i-carbon dioxide (CO2), i-nitrogen oxides (NO) kunye ne-sulfur oxides (SO), eya kungcolisa indawo engqongileyo.Idatha yophando ye-International Maritime Organisation (IMO) ibonisa ukuba iinqanawa ezisebenza nge-diesel kwihlabathi jikelele zikhupha amashumi ezigidi zeetoni ze-NO kunye ne-SO kwi-atmosfera minyaka yonke, ibangela ungcoliseko olukhulu;Ukongeza, isixa esipheleleyo se-CO ekhutshwa luthutho lwaselwandle lwehlabathi likhulu, kwaye isixa esipheleleyo se-CO2 ekhutshiweyo igqithise ukukhutshwa kwerhasi yegreenhouse yonyaka kumazwe adweliswe kwiProtocol yaseKyoto;Ngelo xesha, ngokutsho kwedatha, ingxolo eyenziwa kukusetyenziswa koomatshini abancedisayo ngeenqanawa kwi-port nayo iya kubangela ukungcoliseka kwendalo.
Okwangoku, amanye amazibuko ehlabathi ahambele phambili amkele iteknoloji yamandla onxweme ngokulandelelana kwaye ayinyanzelisa ngokomthetho.UGunyaziwe weZibuko laseLos Angeles laseUnited States upasise umthetho [1] wokunyanzela zonke iitheminali ezikummandla walo ukuba zamkele ubuchwepheshe bamandla onxweme;NgoMeyi ka-2006, iKhomishoni yaseYurophu yapasisa umthetho oyilwayo we-2006/339/EC, owacebisa ukuba amazibuko e-EU asebenzise amandla aselunxwemeni ekukhweliseni iinqanawa.E-China, iSebe lezoThutho lineemfuno ezifanayo zolawulo.Ngo-Epreli ka-2004, owayesakuba nguMphathiswa wezoThutho wakhupha iMimiselo yokuSebenza noLawulo lweZibuko, eyaphakamisa ukuba umbane waselunxwemeni kunye nezinye iinkonzo kufuneka zibonelelwe kwiinqanawa kummandla wezibuko.
Ukongeza, ngokwembono yabanini beenqanawa, ukunyuka kwexabiso le-oli ekrwada kumazwe ngamazwe okubangelwa kukunqongophala kwamandla nako kwenza iindleko zokusebenzisa i-oyile yamafutha ukuvelisa umbane kwiinqanawa ezisondela kwizibuko zinyuke ngokuqhubekayo.Ukuba iteknoloji yamandla onxweme isetyenzisiweyo, iindleko zokusebenza kweenqanawa ezisondela kwi-port ziya kuncitshiswa, kunye neenzuzo ezilungileyo zezoqoqosho.
Ngoko ke, i-port ithatha iteknoloji yamandla onxweme, engahambelani kuphela neemfuno zelizwe kunye nezoshishino zokugcinwa kwamandla kunye nokunciphisa ukukhutshwa kwamandla, kodwa ihlangabezana neemfuno zamashishini ukunciphisa iindleko zokusebenza, ukuphucula ukukhuphisana kwe-terminal kunye nokwakha "izibuko elihlaza".
