ʻO ka uila ka wahie o ka wā e hiki mai ana. A i ʻole i ʻōlelo ʻia mai iā mākou. ʻAʻohe kānalua i ka hiki ke loaʻa iā ia, a no kēia kumu ke hana nei nā kaʻa hoʻopukapuka kālā i loko, akā ʻo ka ʻoiaʻiʻo kēia; ʻo ka laulā o nā kaʻa uila e pili nui ana i ke kaumaha. Ke piʻi ʻoe ma luna o ʻelua tone, he mea maʻamau no ke kaʻa me ka nui o nā pūʻolo pila, ʻaʻohe huelo.
No nā HGV, hiki ke hoʻonui i nā unahi ma luna o 44 tons, ʻaʻole kēia ka nūhou maikaʻi.
Ua hōʻoia ʻia kēia i ka wā i hoʻokau ai ʻo BMW i ka HGV 40-tonne mua loa o ʻEulopa i ka makahiki 2015. Me ka palena kiʻekiʻe o 100km (62 mau mile), ʻaʻole kūpono ia i nā haul lōʻihi. Ua hoʻohana ʻia ke kaʻa no ka lawe ʻana i nā ʻāpana kaʻa ma waena o kahi hale hana BMW a me ke kikowaena logistics o Scherm. Ua hoʻopau i kēia huakaʻi i nā manawa he nui no kekahi mau mahina, a ua kūleʻa pū kekahi. ʻAʻole i hoʻokuʻu ʻia ke kaʻa a, e like me ka BMW, e mālama i 11.8 tonnes o CO2 i kēlā me kēia makahiki. He nui kēlā o CO2 i mālama ʻia, akā naʻe, ʻo ke kaʻa ponoʻī, ʻoiai he hana kupanaha o ka ʻenekinia, ua hoʻopaʻa i kēia ʻoiaʻiʻo maʻalahi:
He ala lōʻihi kā mākou e hele ai ma mua o ka uwila ka wahie kūpono no nā HGV.
He mea maʻalahi ka pilikia o nā ʻenekinia: ʻO ka loaʻa ʻana o kahi kaʻa me ke kaumaha ma mua o 40-tonnes e hāʻawi i ka laulā i hāʻawi ʻia e ka mīkini diesel maʻamau. Hoʻohana ka poʻe kaʻa i ko lākou ola ma ke alanui, a hiki ke hoʻopaʻa maʻalahi i 100,000 mau kilomita i ka makahiki. Pono ka poʻe kaʻa kaʻa a me nā ʻauwaʻa i nā kaʻa e hāʻawi i ka laulā i hiki iā lākou ke hoʻopuka i ka ʻāina. ʻO nā kaʻa kaʻa i hoʻohana ʻia e ka uila i kēia manawa he 100-200km ka maikaʻi loa. Inā mākou e pāpā i nā kaʻa kaʻa diesel a pau ma ke alanui i kēia lā a hoʻololi iā lākou a pau me nā kaʻa uila me ke ʻano o ka manaʻo BMW, e oki ka ʻoihana logistic. A laila, ʻo ka manawa ka hoaaloha maikaʻi loa o ka uila; e lilo ana ka manawa e hoʻomohala i kēia ʻenehana i mea hoʻohana. E lilo ana ka manawa no ke Aupuni Pelekania a me nā ʻauwaʻa e hoʻololi i nā HGV uila.
No laila, inā mamao loa nā HGV uila, he aha ka hopena i kēia manawa? ʻAe, maʻemaʻe maoli nā ʻenekini diesel hou. Hāʻawi lākou i ka CO2 haʻahaʻa, akā nui ka NOx. ʻOi aku ka maʻemaʻe o nā ʻenekini petrol, akā ʻoi aku ka liʻiliʻi. ʻO ka hopena e like me ka BMW i3 me kahi mea hoʻonui; Aia kēia kaʻa i kahi pahu pākaukau a me kahi ʻenekini petrol i mea hoʻihoʻi, e hoʻopiha hou i nā pila. Hāʻawi ia i ka mpg maikaʻi loa, a me ka laulā maikaʻi. Inā loaʻa i kahi HGV kēia ʻenehana, ʻoi aku ka maʻemaʻe ma mua o kā mākou i kēia manawa.
