ʻO ka kumuwaiwai kūlohelohe ʻano pau ʻole, i kapa ʻia hoʻi hou, nā mea i hoʻolilo ʻole ʻia, ʻo ia, hiki ke hoʻohana mau ʻia. Eg ikehu lā, ikehu makani.
ʻOkoʻa lākou i nā kumuwaiwai pau ʻole Hou Hou, ʻo ia nā mea hiki ʻole ke hana hou ʻia, a i ʻole hana ʻia i ka wikiwiki ʻoi aku ka liʻiliʻi ma mua o kā lākou hoʻopau ʻia (e laʻa me ka lāʻau). ʻO kekahi mau laʻana o nā kumuwaiwai pau ʻole ka aila, kekahi mau metala, a me ka ʻaila kūlohelohe.
I kēia lā, ʻo ka hapa nui o ka ikehu a mākou e hoʻopau ai ma ka honua holoʻokoʻa mai nā waiwai hiki ʻole. Hoʻohana mākou i kēlā ikehu e loaʻa uila, hoʻomehana, i ka ʻoihana a i ka halihali. ʻOiai ʻoi aku ka maikaʻi o kēia mau kumuwaiwai paʻa o ka paʻa mau i ka hakahaka a me ka manawa, loaʻa iā lākou ka hemahema ʻaʻole wale e holo lākou i ka wā waena akā hana pū lākou i kahi nui o ka ikehu. kinoea hoʻohaumia. No laila, ke ʻimi nei e pani iā lākou me nā kumuwaiwai pau ʻole.
Nā ʻano
- Mai holo i waho: E like me eg. ka makani, a i ʻole he mea hou paha ia, ʻo ia hoʻi, hiki ke hana ʻia i kahi wikiwiki kiʻekiʻe ma mua o ka mea i hoʻopau ʻia, e laʻa me kekahi mau mea kanu, i hoʻohana ʻia e hana i nā wahie e like me biodiesel.
- Kūlike ʻole pinepine ʻole: Kūlike ʻole lākou i ka manawa a me ke ākea, no ka laʻana, ʻaʻole hiki iā mākou ke loaʻa ka ikehu o ka lā i nā manawa āpau, no ka mea e ʻae iā ia e noho i ka pō a i ka wā i uhi ʻia ka lani. E pili ana i ka hakahaka, aia nā wahi kahi e hiki ai ke hoʻohana i ka ikehu o ka makani, no ka mea, ikaika ka makani, ʻoiai ʻaʻole i kekahi.
- ʻĀpana puehu: ʻO ka ikaika o ka ikehu ma ka laulā pono e loaʻa mai kahi wahi nui loa, no ka laʻana pono ia e hoʻohana i kahi nui o nā paneli lā e loaʻa ai ka ikehu e pono ai. I nā huaʻōlelo ʻē aʻe, haʻahaʻa ka ikehu o kēlā me kēia mika mika, e hana ana i pipiʻi e loaʻa. Eia naʻe, kūʻokoʻa ia, no ka mea, ʻokoʻa ka laʻana o ka ikehu uila, ʻaʻole pono e pili i kahi pūnaewele.
- Nā ikehu maʻemaʻe: ʻAʻole like me nā wahie fossil, ʻaʻole lākou e hoʻokuʻu i ke kalapona kalapona i ka lewa.
Nā laʻana o nā kumuwaiwai pau ʻole
- Ikehu lā: Kuhi ka lā i ka radiation i loaʻa i ko mākou Honua ka nui nui i loko o hoʻokahi hola wale nō e lawa pono ai ka ikaika o ka honua holoʻokoʻa no hoʻokahi makahiki. ʻO ka ʻenehana e hoʻohana i kēia ikehu ka ikehu wale nō photovoltaic. Hoʻohana ʻia kahi hāmeʻa i kapa ʻia ʻo photovoltaic cell. I kahi mea liʻiliʻi, hoʻohana pū ʻia ka ikehu uila thermoelectric, kahi e hoʻohana ai i nā aniani e noʻonoʻo ai i ka lā ma kahi ʻili liʻiliʻi, e hoʻohuli ana i ka ikehu lā i ka wela, e hoʻohuli ai i ka ʻenekini wela e hoʻoulu ai i ka uila.
- Mana makani: Hoʻohana ʻia ka ikehu e hiki mai ka makani ma o ke kaʻapuni ʻana o nā mīkini uila. ʻO nā pehu makani a mākou e ʻike nei i ke ʻano o nā aniani keʻokeʻo nui me ʻekolu mau lau lahilahi i kapa ʻia he mau pehu uila. Ua hana ʻia lākou ma 1980 i Denmark.
- Ka mana Hydroelectric: Hoʻohana i ka ikehu neoneo a me ka hiki o ka neʻe ʻana o ka wai, ʻo ia hoʻi nā muliwai, nā wailele a me nā moana. ʻO ke ʻano maʻamau o ka loaʻa ʻana o ka ikehu uila ʻo ia nā mea kanu mana hydroelectric. ʻOiai ʻoi aku ka maikaʻi o ka lawe ʻole ʻana i nā mea haumia a i ʻole he waiwai pau ʻole, he hopena maikaʻi loa ia ma muli o ke kahe wai a nā mea kanu hydroelectric.
- Ikehu Geothermal: Ma loko, he wela ko kā mākou honua, i hiki ke hoʻohana ʻia e hana i ka ikehu. Piʻi ka mahana me ka hohonu. ʻOiai anuanu ka honua ma ka ʻili, hiki iā mākou ke nānā i nā hopena o ka wela o ka honua i nā geysers, nā punawai wela, a me nā pele pele.
- ʻO Biofuels: ʻAʻole ia kahi kumu kikoʻī pau ʻole akā ʻoi aku ka hou hou, ʻo ia hoʻi, hiki ke hana ʻia i kahi wikiwiki ʻoi aku ma mua o kāna hoʻohana ʻana. Mai nā mea kanu e like me ka kānana, kō, kōā a me ka wili, hiki ke hana ʻia nā wai ʻalekō a i ʻole nā aila e hoʻohana i wahie. ʻOi aku ka liʻiliʻi o kāna hoʻokuʻu ʻana o ke kalapona ma mua o ka mea i hoʻoili ʻia e nā wahie fossil e like me ka aila.
E hāhai me:
- Nā kumuwaiwai hou
- Kumuwaiwai nonrenewable
