ʻO ka hoʻohana ʻana i ka ʻumekaumaha o ka wai kahe e hoʻoulu ai i ka uila ua kapa ʻia ʻo hydropower.
Hoʻohana ʻia ka ʻumekaumaha o ka wai no ka hoʻohuli ʻana i nā turbines, ka mea e hoʻokele ai i nā magnets i nā mea hana hoʻololi e hana ai i ka uila, a ua helu pū ʻia ka ikehu wai ma ke ʻano he kumu ikehu hou. ʻO ia kekahi o nā ʻenehana kahiko loa, ʻoi aku ka maʻalahi a maʻalahi hoʻi.
Hoʻokaʻawale ʻia ka hydropower i ʻehā mau ʻāpana: maʻamau (dams), pumped storage, muliwai a me waho (tidal). ʻO ka hydropower kekahi o nā kumu uila nui ʻekolu o ka honua, a ʻo nā mea ʻelua ʻē aʻe e puhi ana i nā wahie fossil a me nā wahie nuklea. I kēia lā, ʻo ia ka hapaono o ka nui o ka mana o ka honua.
Nā pōmaikaʻi o ka hydropower
Palekana a maʻemaʻe-ʻAʻole like me nā kumu ikehu ʻē aʻe e like me nā wahie mōʻalihaku, maʻemaʻe a ʻōmaʻomaʻo e like me ka ikehu nuklea a me ka ikehu biomass. ʻAʻole hoʻohana a hoʻokuʻu paha kēia mau mea mana i ka wahie, no laila ʻaʻole lākou e hoʻokuʻu i nā kinoea ʻōmaʻomaʻo.
Hiki ke hoʻohou-ua manaʻo ʻia ka ikehu hou no ka mea hoʻohana ʻo ia i ka wai o ka honua e hana i ka uila. Hoʻihoʻi hou ʻia ka wai i ka honua ma ke ʻano kūlohelohe me ka ʻole o ka pollution. Ma muli o ka pōʻaiapuni wai maoli, ʻaʻole e pau.
ʻO ke kumu kūʻai-ʻOiai ke kumukūʻai nui o ke kūkulu ʻana, ʻo ka hydropower kahi kumu hoʻokūkū kūʻai kumu kūʻai ma muli o ka haʻahaʻa haʻahaʻa o ka mālama ʻana a me nā koina hana.
Puna hikiwawe-He kumu maʻalahi kēia o ka uila no ka mea hiki i kēia mau mea mana ke piʻi wikiwiki a hoʻohaʻahaʻa ma muli o ke koi ikaika. ʻOi aku ka pōkole o ka manawa hoʻomaka o ka turbine wai ma mua o ka turbine mahu a i ʻole ka turbine kinoea.
ʻO nā hoʻohana ʻē aʻe-I ka hana ʻana o nā pāhana hydropower i loko o nā waihona nui, hiki ke hoʻohana ʻia kēia wai no ka hoʻoulu ʻana a me ka iʻa. Hiki ke hoʻohana ʻia ka loko i hoʻokumu ʻia ma hope o ka wai no nā haʻuki wai a me nā hana leʻaleʻa, e lilo ia i mea hoʻokipa a loaʻa kālā.
Nā pōʻino o ka hydropower
ʻO ke kumu kūʻai kiʻekiʻe loa-he pipiʻi loa kēia mau mea kanu mana a me nā pā i kekahi manawa. He kiʻekiʻe loa ke kumukūʻai kūkulu.
ʻO ka pilikia o ka hāʻule ʻole-ma muli o ke kahe ʻana, paʻa nā dam i ka nui o ka wai, nā pōʻino kūlohelohe, nā pōʻino i hana ʻia e ke kanaka, a me ka maikaʻi o ke kūkulu ʻana i nā hopena pōʻino no nā wahi o lalo a me nā ʻoihana. Hiki i ia mau hemahema ke hoʻopilikia i ka lako mana, nā holoholona a me nā mea kanu, a hiki ke kumu i nā poho nui a me nā pōʻino.
Hoʻopau kaiaola-Na nā loko wai nui e hoʻopiha i nā wahi nui o ka uka o ka puʻu i ka wai, i kekahi manawa e luku ana i nā ʻāina haʻahaʻa, nā awāwa, nā ululāʻau a me nā mauʻu. I ka manawa like, e hoʻopilikia pū ia i ka kaiaola wai a puni ka mea kanu. He hopena nui ia i ka iʻa, ka moa wai a me nā holoholona ʻē aʻe.
