I kekahi mau makahiki 2, e hoʻolaha ʻia ka ethanol gasoline. He kūpono anei kāu kaʻa no ka hoʻohana ʻana i ka ethanol gasoline?

I ka makahiki i hala aku nei, ua hoʻolaha ka pūnaewele mana o ka National Energy Administration e hoʻonui a hoʻonui ʻia ka hoʻolaha ʻana o ka ethanol gasoline, a e hoʻokō ʻia ka uhi piha i ka makahiki 2020. ʻO ia hoʻi, i nā makahiki 2 e hiki mai ana, e hoʻomaka mālie mākou e E hoʻohana i ka ethanol E10 me 10% ethanol. ʻO ka ʻoiaʻiʻo, ua hoʻomaka ʻo E10 ethanol gasoline i ka hana hoʻokele ma mua o 2002.

He aha ka ethanol gasoline? E like me nā kūlana aupuni o koʻu ʻāina, hana ʻia ka ʻaila ethanol ma o ka hui ʻana i 90% ʻaila maʻamau a me 10% wahie ethanol. Hoʻohana maʻamau ʻo 10% ethanol i ka kulina i mea maka. ʻO ke kumu i hoʻolaha a hoʻolaha ai ka ʻāina i ka ethanol gasoline ma muli o ka pono o ka mālama ʻana i ke kaiapuni a me ka piʻi ʻana o ka noi home a me ka piʻi ʻana o ka noi no ka palaoa (corn), no ka mea, ʻo koʻu ʻāina ka nui o ka ʻohi palaoa i kēlā me kēia makahiki. ʻoi aku ka nui o ka hōʻiliʻili ʻana o ka palaoa kahiko. Manaʻo wau ua ʻike nā mea a pau i nā nūhou pili. ! Eia kekahi, ʻuʻuku nā kumu ʻaila ʻaila o koʻu ʻāina, a hiki i ka hoʻomohala ʻana i ka wahie ethanol ke hōʻemi i ka hilinaʻi ʻana i ka ʻaila i lawe ʻia mai. He ʻano wahie ka Ethanol ponoʻī. Ma hope o ka hui ʻana i kahi nui o ka ethanol, hiki iā ia ke mālama i ka nui o nā kumu waiwai kerosene i hoʻohālikelike ʻia me ka ʻaila maʻemaʻe ma lalo o ka maikaʻi like. No laila, manaʻo ʻia ka bioethanol he huahana ʻē aʻe e hiki ke pani i ka mana fossil.

He hopena nui anei ka ethanol gasoline i nā kaʻa? I kēia manawa, hiki i ka hapa nui o nā kaʻa ma ka mākeke ke hoʻohana i ka ʻaila ethanol. ʻO ka ʻōlelo maʻamau, ʻoi aku ka kiʻekiʻe o ka ʻai wahie o ka ethanol gasoline ma mua o ka ʻaila maʻemaʻe, akā ʻoi aku ka kiʻekiʻe o ka helu octane a ʻoi aku ka maikaʻi o ka hana anti-kikeke. Hoʻohālikelike ʻia me ka ʻaila maʻamau, hoʻomaikaʻi ʻole ka ethanol i ka hana wela ma muli o kona ʻike oxygen kiʻekiʻe a me ka hoʻopau piha ʻana. Eia nō naʻe, ma muli o nā ʻano o ka ethanol i ʻokoʻa me ka ʻaila. Hoʻohālikelike ʻia me ka ʻaila maʻamau, ʻoi aku ka mana o ka ethanol gasoline i nā wikiwiki kiʻekiʻe. ʻOi aku ka maikaʻi o ka mana ma nā rev haʻahaʻa. ʻOiaʻiʻo, ua hoʻohana ʻia ka ethanol gasoline ma Jilin no ka manawa lōʻihi. ʻO ka ʻōlelo kikoʻī, he hopena kona i ke kaʻa, akā ʻaʻole maopopo, no laila ʻaʻole pono ʻoe e hopohopo!

Ma waho aʻe o Kina, ʻo wai nā ʻāina ʻē aʻe e hoʻolaha nei i ka ʻaila ethanol? I kēia manawa, ʻo Brazil ka ʻāina kūleʻa loa i ka hoʻolaha ʻana i ka ʻaila ethanol. ʻAʻole ʻo Brazil wale nō ka lua o ka mea hana wahie ethanol nui loa ma ka honua, akā ʻo ka ʻāina kūleʻa loa i ka hoʻolaha ʻana i ka ʻaila ethanol ma ka honua. I ka makahiki 1977, ua hoʻohana ʻo Brazil i ka ʻaila ethanol. I kēia manawa, ʻaʻohe ʻaila maʻemaʻe e hoʻohui ʻia i nā keʻena kinoea a pau ma Brazil, a kūʻai ʻia nā ʻaila ethanol āpau me ka ʻike mai ka 18% a hiki i ka 25% ke kūʻai ʻia.
