Ke holomua: ʻOi aku ka maikaʻi o nā kaʻa uila ma mua o ka manaʻo?

Ka poʻe Kelemania e pani ana mai kā lākou kaʻa a me ke hoʻololi ʻana e pili ana i ke ʻano e hoʻopilikia ai kekahi. ʻO kahi ala e hiki ai ke hoʻohui i nā mea ʻelua e like me ka hoʻololi ʻana i nā kaʻa kaʻa uila, akā aia nō kekahi kekahi mau hoʻohewa ʻana o kēia koho. Ua ala mai ka nīnau: kaʻa kaʻa uila - ʻae a i ʻole? 

Pro:

• ulu ana: Ke kūʻai aku nei ka poʻe nui aʻe i nā kaʻa uila, ʻoi aku ka nui o nā ʻoihana kālā ke hoʻoili i ka hoʻomohala hou aʻe o nā pahu hana, e like me ka wikiwiki a me ka pā. Ma muli o ke koi nui aʻe, e hoʻonui ʻia ana nā ʻoihana halihali i ka pūnaewele lawe moku.
• koina: ʻO nā kumukūʻai holo kaʻa o ka pahu kaʻa he haʻahaʻa ma mua o nā pahu a i kahi kaʻa make, a me ka loiloi e pono ai. Eia kekahi, ʻo ke kumukūʻai kūʻai, ʻo ia ka mea e paleʻole ai nā mea he nui, e hoʻohaʻahaʻa i ka wā e hiki mai ana. ʻOi aku ka uku o ka mālama mālama ʻia no ka mea ʻoi aku ka liʻiliʻi o kahi kaʻa uila ma mua o kahi kaʻa ʻokoʻa - no ka laʻana, ka neʻe, ka mea hoʻohuli a me ka V-belt.
• environmentally aloha: He kaʻa a mana i hoʻouka ʻia e ka ʻōmaʻomaʻo ʻōiwi i ka hoʻohiwahiwa kaiāulu, wikiwiki koke i ka hoʻokō kiʻekiʻe a wikiwiki hoʻi me ke kī ʻole ʻole.

Con:

• kuleana: He mau papa uila lithium-ion. Pau kēia i ka ikaika nui ma ka hana. Eia kekahi, ʻo ka lōʻihi o ke kaona o ke kekona he ʻumi wale nō makahiki. ʻAʻole maʻalahi nā pahu ʻeke hou a no laila ke kaumaha ma nā wahi kūlohelohe. Eia nō naʻe, hiki i kekahi o kēia mau pilikia ke mālama ʻia e nā hanana e pili ana.
• ʻO ka lāʻau: Inā inā he lehulehu ʻoi aku ka nui o nā kaʻa uila, pono e hoʻoulu ʻia kekahi kaila - e hiki mai ana mai nā mea kanu lā e hoʻoheheʻe ʻia me nā mea kiʻekiʻe loa. ʻOi aku kahi hapakolu o nā uila i nā kaʻa uila e holo ana i Kelemānia e hele mai nā mea kanu ahi hoʻomana i hana.

I ka makahiki 2017, ua paʻi nā kānaka ʻepekema i ka Ke Kulanui ʻOihana Pū ʻIa Kūʻai ʻo Sweden (IVL) kahi hōʻike e pili ana i ka weliweli kaulike o nā kaʻa uila a loaʻa i nā hualoaʻa: ʻoi aku ka maikaʻi o ka pale kaulike kūlohelohe ma mua o ʻelua mau makahiki i hala. Kekahi luhi - ka hoʻohana 'ana i ka hana o nā pā lithium-ion Eia naʻe, ʻike ka noiʻi o kēia manawa i nā waiwai hana hana pālolo i kēia manawa i ka lima me ka nui o nā mea i lawe ʻia i ka CO2. Loaʻa kekahi hoʻomaikaʻi hou i ka ikehu hou. ʻO ka pilikia hoʻokahi i ʻike ʻole ʻia ka noiʻi ʻana, ʻo ia ka hoʻokuʻu ʻana i nā kao ʻaila i hana kūleʻa i ka wā e hoʻi hou ʻia ka pāā. Nui nā ʻano hana loea hou, akā pili nā mea kanu i ko lākou helu.

ʻO ke koho makemake kūlohelohe maikaʻi, ʻo ia ka mea, ʻo ke kūʻai ʻana i kahi kaʻa i hoʻohana ʻia. A i ʻole, e like me Volker Quaschning, wahaheʻe no nā ʻōnaehana hoʻoikaika regenerative i hoʻokahi hoakaka penei:

 "I mea e hoʻokō ai i ka ʻikena pale pale kai ʻo Paris a i ka hoʻopaloli ʻana i ka hoʻoku ʻana o ka honua i ka 1,5 degere Celsius e like me ka palekana, e hōʻemi mākou i nā mea hoʻoheheʻe hale palemila ma ka honua i loko o 20 mau makahiki. Ma ke kahua o ka halihali pilikino, ʻo ia ke koho no ka hoʻohana ʻana i kahi uila uila kahi e hana ʻia ai ka ikehu mai nā ʻenehana hou. ʻO kaʻoiaʻiʻo, pono e hana pono i ka hana ʻana o nā kaʻa a me nā ʻenehana pono ʻole. I kēia manawa hou ʻaʻole pono nā haʻawina hoʻokele e ola ana. "
