ʻO ka ikehu hou ka ikehu i loaʻa mai nā kumu kūlohelohe i hoʻopiha hou ʻia ma kahi kiʻekiʻe ma mua o ka pau ʻana.ʻO ka lā a me ka makani, no ka laʻana, he mau kumu ia e hoʻopiha mau ʻia.Nui nā kumu ikehu hou a puni mākou.
ʻO nā wahie fossil - ka lanahu, ka aila a me ke kinoea - ma ka ʻaoʻao ʻē aʻe, he mau kumuwaiwai hiki ʻole ke hoʻololi ʻia e lawe i nā haneli miliona mau makahiki e hana ai.ʻO nā wahie mōʻalihaku, ke puhi ʻia e hana i ka ikehu, e hoʻoheheʻe ʻia ke kinoea hoʻomaʻemaʻe ʻino, e like me ka carbon dioxide.
ʻO ka hoʻoulu ʻana i ka ikehu hou e hana i nā hoʻokuʻu haʻahaʻa haʻahaʻa ma mua o ka puhi ʻana i nā wahie fossil.ʻO ka hoʻololi ʻana mai nā wahie mōʻalihaku, ʻo ia ka mea i kēia manawa no ka liona o ka hoʻokuʻu ʻana, i ka ikehu hou ke kī i ka hoʻoponopono ʻana i ka pilikia aniau.
ʻOi aku ka maʻalahi o nā mea hou i ka hapa nui o nā ʻāina, a hoʻonui i ʻekolu mau hana ma mua o nā wahie fossil.
Eia kekahi mau kumu maʻamau o ka ikehu hou.
IKE LAULA
ʻO ka ikehu o ka lā ka mea nui loa o nā kumuwaiwai a pau a hiki ke hoʻohana ʻia i ka wā ao.He 10,000 ka nui o ka nui o ka ikehu o ka la e ka Honua ma mua o ka nui o ka hoopau ana o ke kanaka i ka ikehu.
Hiki i nā ʻenehana o ka lā ke hāʻawi i ka wela, ka hoʻoluʻu, ke kukui kūlohelohe, ka uila, a me nā wahie no ka nui o nā noi.Hoʻololi nā ʻenehana o ka lā i ka ikehu uila ma o nā panela photovoltaic a i ʻole ma o nā aniani e kālele ana i ka radiation lā.
ʻOiai ʻaʻole i hāʻawi like ʻia nā ʻāina āpau me ka ikehu lā, hiki i kēlā me kēia ʻāina ke hāʻawi nui i ka hui ʻana o ka ikehu mai ka ikehu lā.
Ua hāʻule nui ke kumukūʻai o ka hana ʻana i nā panela lā i nā makahiki he ʻumi i hala aku nei, ʻaʻole hiki ke kūʻai wale ʻia akā ʻo ia ka ʻano uila ʻoi loa.He 30 mau makahiki ka lōʻihi o ke ola ʻana o nā panela solar, a hele mai i nā ʻano aka like ʻole ma muli o ke ʻano o nā mea i hoʻohana ʻia i ka hana ʻana.
IKE MAKANI
Hoʻohana ka makani makani i ka ikehu kinetic o ka neʻe ʻana o ka ea ma o ka hoʻohana ʻana i nā turbine makani nui ma ka ʻāina (ma uka) a i ʻole ma ke kai a i ʻole ka wai maʻemaʻe (ma waho o kahakai).Ua hoʻohana ʻia ka ikehu makani no nā makahiki he mau makahiki, akā, ua ulu aʻe nā ʻenehana ikehu makani uka a me waho i nā makahiki i hala iho nei e hoʻonui i ka uila i hana ʻia - me nā turbine kiʻekiʻe a me nā anawaena rotor nui aʻe.
'Oiai he 'oko'a ka 'awelika o ka makani ma ka wahi, 'oi aku ka nui o ka ikehu makani o ka honua ma mua o ka hana 'aila honua, a he nui ka mana ma ka hapa nui o ka honua e hiki ai ke ho'olaha i ka ikehu makani.
Nui nā wahi o ka honua i ka makani ikaika, akā ʻo nā wahi maikaʻi loa no ka hoʻoulu ʻana i ka makani he mau wahi mamao.Hāʻawi ka mana makani waho i ka mana nui.
IKEA GEOTHERMAL
Hoʻohana ka ikehu Geothermal i ka ikehu wela mai loko mai o ka Honua.Lawe ʻia ka wela mai nā waihona wai wela me ka hoʻohana ʻana i nā pūnāwai a i ʻole nā ala ʻē aʻe.
ʻO nā waihona wai i lawa maoli ka wela a me ka permeable, ua kapa ʻia ʻo ia he wai wai wela, akā ʻo nā waihona i lawa ka wela akā i hoʻomaikaʻi ʻia me ka hoʻoulu hydraulic ua kapa ʻia nā ʻōnaehana geothermal hoʻonui.
Aia ma ka ʻilikai, hiki ke hoʻohana ʻia nā wai o nā mahana like ʻole e hana i ka uila.ʻO ka ʻenehana no ka hoʻoulu ʻana i ka uila mai nā waihona wai wai wela he makua a hilinaʻi hoʻi, a ua hana ʻia ma mua o 100 mau makahiki.
PALAPALA
Hoʻohana ka hydropower i ka ikehu o ka wai e neʻe ana mai kahi kiʻekiʻe a i lalo.Hiki ke hana ʻia mai nā loko a me nā kahawai.Ke hilinaʻi nei nā mea kanu wai wai i ka wai i mālama ʻia i loko o kahi waihona, aʻo nā mea kanu wai wai kahe e hoʻohana i ka ikehu mai ke kahe ʻana o ka muliwai.
He nui nā hoʻohana ʻana i nā waihona wai wai - hāʻawi i ka wai inu, wai no ka hoʻoulu ʻana, ka hoʻomalu wai a me ka maloʻo, nā lawelawe hoʻokele, a me ka lako ikehu.
ʻO ka Hydropower i kēia manawa ke kumu nui loa o ka ikehu hou i ka ʻāpana uila.Ke hilinaʻi nei ia i nā ʻano ua paʻa mau, a hiki ke hoʻopilikia maikaʻi ʻia e nā maloʻo a i ʻole nā hoʻololi ʻana i nā kaiaola e pili ana i nā ʻano ua.
Hiki i nā ʻōnaehana pono e hana i ka hydropower ke hopena i nā kaiaola ma nā ala ʻino.No kēia kumu, manaʻo ka poʻe he nui ka wai liʻiliʻi he koho ʻoi aku ka maikaʻi o ke kaiapuni, a kūpono hoʻi i nā kaiāulu ma nā wahi mamao.
IKE O KA MOANA
Loaʻa ka ikehu moana mai nā ʻenehana e hoʻohana ana i ka ikehu kinetic a me ka wela o ka wai kai – nā nalu a i ʻole nā au e like me ka hana ʻana i ka uila a me ka wela.
Aia nā ʻōnaehana ikehu moana i ka hoʻomaka ʻana o ka hoʻomohala ʻana, me ka nui o nā hawewe prototype a me nā hāmeʻa o kēia manawa e ʻimi ʻia nei.ʻOi aku ka maʻalahi o ka manaʻo o ka ikehu moana ma mua o nā koi o ka ikehu kanaka.
ELELE BIO
Hoʻokumu ʻia ka bioenergy mai nā ʻano mea kūlohelohe, i kapa ʻia ʻo biomass, e like me ka lāʻau, ka lanahu, ka lepo a me nā manure ʻē aʻe no ka hana wela a me ka mana, a me nā mea kanu mahiʻai no ka biofuels wai.Hoʻohana ʻia ka hapa nui o ka biomass ma nā kuaʻāina no ka kuke ʻana, ka kukui a me ka hoʻomehana ʻana o ka lewa, ma ka maʻamau e ka poʻe ʻilihune ma nā ʻāina ulu.
Aia nā ʻōnaehana biomass hou i nā mea kanu i hoʻolaʻa ʻia a i ʻole nā lāʻau, nā koena mai ka mahiʻai a me ka ulu lāʻau, a me nā kahawai ʻōpala organik like ʻole.
Hoʻokumu ka ikehu i hana ʻia e ka puhi ʻana i ka biomass i nā hoʻokuʻu kinoea hoʻomehana honua, akā ma nā pae haʻahaʻa ma mua o ka puhi ʻana i nā wahie mōʻalihaku e like me ka lanahu, ka aila a i ʻole ke kinoea.Eia nō naʻe, pono e hoʻohana wale ʻia ka bioenergy i nā noi liʻiliʻi, no ka mea e pili ana i nā hopena kūlohelohe maikaʻi ʻole e pili ana i ka piʻi nui ʻana o nā ululāʻau a me nā mea kanu bioenergy, a me ka hopena o ka hoʻopau ʻana i ka ululāʻau a me ka hoʻololi ʻana i ka ʻāina.
