5 mau mea nui e ʻike e pili ana i ka biofuels
Inā ʻoe i ʻike mua i nā pōmaikaʻi kaiapuni o ka hoʻohana ʻana i nā biofuels, a i ʻole e noʻonoʻo ana inā makemake ʻoe e hoʻohana ia mea i kāu kaʻa e hiki mai ana, pono e hoʻomaopopo i ke ʻano o ka hana ʻana. ʻO nā biofuels, i hana ʻia mai nā ʻōpala a me nā huahana mahiʻai, he kumu hou o ka ikehu i ʻoi aku ka maikaʻi a ʻoi aku ka maʻemaʻe ma mua o ke kinoea a me ka diesel. No laila, lilo ia i mea koʻikoʻi no ka poʻe makemake e hōʻemi i ko lākou hopena ma ka ʻāina a mālama i ke kālā ma ke kahua kinoea. Aia ma lalo iho kekahi mau mea nui e pono ai ʻoe e ʻike e pili ana i ka biofuels.
ʻEkolu ʻano
Loaʻa nā biofuels ma ke ʻano o ka biomethane, i loaʻa mai nā mea kūlohelohe i ko lākou decompose; ʻO ka ethanol, ka mea i hana ʻia me ka starch, sugars a me cellulose a hoʻohana ʻia i kēia manawa i nā hui ʻaila; a me ka biodiesel, i loaʻa mai ka ʻōpala kuke a me ka ʻaila meaʻai. Aia kekahi mau mea ola kino algal e koi ana i ka liʻiliʻi o ka ʻāina a hiki ke hoʻololi ʻia e hana i ka nui o ka aila a i ʻole biofuels.
Liʻiliʻi nā hoʻokuʻu
ʻO ka makemake mua i nā biofuels i hoʻāla ʻia e nā kūlana hoʻokuʻu kaʻa. ʻOi aku ka maʻemaʻe o kēia mau wahie, no laila e emi mai nā mea ʻala, nā kinoea ʻōmaʻomaʻo a me nā hoʻokuʻu sulfur tailpipe.
ʻIke ikehu
ʻO ka ikehu o nā biofuels kahi mea e noʻonoʻo nui ai i ka wā e nānā ai e pani i nā wahie maʻamau. Loaʻa i ka Biodiesel i kēia manawa ka ikehu ma kahi o 90 pakeneka o ka mea i hāʻawi ʻia e ka petroleum diesel. Hāʻawi ka Ethanol ma kahi o 50 pakeneka o ka ikehu o ka ʻaila, a ʻo ka butanol e hāʻawi ma kahi o 80 pakeneka o ka ikehu o ka ʻaila. ʻO kēia haʻahaʻa haʻahaʻa o ka ikehu ka hopena i nā kaʻa e hele ana i nā mile liʻiliʻi ke hoʻohana i ka nui like o kēlā me kēia wahie.
He pilikia nā koi ʻāina
ʻOiai nā pōmaikaʻi ʻike o ka hoʻohana ʻana i nā biofuels, ʻo nā ʻano hana hana i kēia manawa ke koho ʻole ʻia no ka hana nui. ʻO ka nui o ka ʻāina e pono ai no ke kanu ʻana i nā pūnāwai e hiki ke hoʻohana ʻia e hana ai i ka ʻaila. No ka laʻana, he mea kaulana ka jatropha. No ka hoʻokō ʻana i ka noi honua no ka wahie, pono e kanu i kēia mea ma kahi ʻāpana o ka nui o ʻAmelika Hui Pū ʻIa a me Russia i hui pū ʻia.
Ke hoʻomau nei ka noiʻi
ʻOiai ʻaʻole hiki ke hana nui i nā biofuels i kēia manawa ma ka pae honua, ke hana nei nā ʻepekema e ʻimi i nā ala e hōʻemi i nā koi ʻāina i mea e maʻalahi ai ka hoʻohana ʻana i nā biofuels i ka ʻoihana kaʻa.
