I te tere o te horapa o te mākete waka hiko o te ao, kua noho te whanaketanga o ngā hanganga utu hei mea nui. I roto i ēnei, ko ngā teihana utu DC, hei tikanga utu tino matatau me te watea, kei te haere haere tonu hei kaupapa matua o te whatunga utu waka hiko.
E ai ki te ingoa, he taputapu te teihana utu hiko DC e utu ana i ngā pākahiko waka hiko mā te whakamahi i te au tika. Ki te whakatauritea ki ngā teihana utu hiko AC tuku iho, he nui ngā painga o ngā teihana utu hiko DC, arā, he tere te utu me te tino whai hua. Ka taea e rātou te huri tika i te mana AC mai i te whatunga hiko ki te mana DC, ka utu tika i te pākahiko o te waka, ā, ka whakaitihia te wā utu. Hei tauira, ka taea e te teihana utu hiko DC 150kW te utu i te waka hiko ki te 80% i roto i te 30 meneti, engari ko te teihana utu hiko AC ka roa pea i raro i ngā āhuatanga ōrite.
Mō te hangarau, he maha ngā hangarau matua e whakamahia ana i roto i te hoahoa me te hanga o ngā teihana utu hiko DC. Tuatahi, ko te hangarau whakawhiti hiko, e whakamahi ana i ngā kaitahuri whai hua hei huri i te hiko AC ki te hiko DC pumau. Tuarua, ko te pūnaha whakamatao; nā te kaha nui e uru ana ki te utu tere, he mea nui te pūnaha whakamatao whai hua hei whakarite i te mahi haumaru me te pumau o ngā taputapu. Hei tāpiri, ka whakauruhia e ngā teihana utu hiko DC hou ngā pūnaha whakahaere atamai ka taea te aroturuki i ngā tawhā rerekē i te wā tūturu i te wā e utu ana, pērā i te ngaohiko, te iahiko, me te pāmahana, kia pai ai te utu me te haumaru.
He mea nui te horapa haere o ngā teihana utu hiko DC, ehara i te mea mō ngā kaiwhakamahi waka hiko anake, engari mō te whanaketanga matomato o te hapori whānui. Tuatahi, ka whakarei ake te kaha utu tere i te whai huatanga o te whakamahi waka hiko, ka whakakore i te "manawanui tawhiti" o ngā kaiwhakamahi, ā, ka whakatairanga i te tango waka hiko. Tuarua, ka taea te whakakotahi i ngā teihana utu hiko DC me ngā pūnaha whakaputa pūngao hou (pērā i te pūngao o te rā me te hau). Mā roto i ngā whatunga atamai, ka taea te whakamahi pai i te hiko matomato, ka whakaiti i te whakawhirinaki ki ngā wahie pūmua tuku iho, ā, ka whakaiti i ngā tukunga waro.
I tēnei wā, he maha ngā whenua me ngā rohe o te ao e kaha ana ki te whakatairanga i te hanganga o ngā teihana utu hiko DC. Hei tauira, ko Haina, te mākete waka hiko nui rawa atu o te ao, kua whānuitia te whakatinanatanga o ngā teihana utu hiko DC ki ngā tāone nui me ngā rohe ratonga huarahi. He maha hoki ngā whenua Pākehā e kaha ana ki te whakatū whatunga utu tere-teitei, me te whakamahere kia tutuki he kapinga whānui i ngā tau e haere ake nei. I te Hononga o Amerika, ko te mahi tahi i waenga i te kāwanatanga me ngā umanga tūmataiti kei te whakateretere i te hanganga o ngā teihana utu hiko DC puta noa i te motu.
Ki te titiro whakamua, he tino whai hua ngā tūmanakohanga whanaketanga o ngā teihana utu hiko DC. Mā te whanaketanga tonu o te hangarau, ka piki ake ngā tere utu, ā, ka heke haere te utu o ngā taputapu. Heoi anō, mā te ia o te mātauranga me te whatunga o ngā teihana utu ka taea e rātou te whai wāhi nui ake i roto i ngā tāone atamai me te kawe waka atamai.
Hei whakamutunga, hei te mata o te hangarau utu waka hiko, kei te whakarerekē ngā teihana utu DC i ā tātou tauira haere me te whakamahinga pūngao. Ka whakaratohia e rātou he wheako utu watea mō ngā kaiwhakamahi waka hiko, ā, ka whai wāhi ki te whanaketanga matomato o te ao. I te heke mai, he nui ngā take e tumanakohia ai e tātou, me te whānui o te whakamahinga o ngā teihana utu DC me te auahatanga hangarau tonu, ka tino arahi ngā waka hiko i tētahi wā hou o te whanaketanga tere.
