Ua hoʻokuʻu aku nei ka US Energy Information Administration (EIA) i kahi hōʻike e hōʻike ana mai ke kauwela o kēia makahiki, ua pā mai ka maloʻo loa ma ʻAmelika Hui Pū ʻIa, e hoʻemi ana i ka hana hydropower ma nā wahi he nui o ka ʻāina no kekahi mau mahina i hala. Aia ka nele o ka uila ma ka mokuʻāina, a ke kaumaha nui nei ka pūnaewele ʻāpana.
Ua emi ka hana mana hydroelectric no nā mahina
Ua kuhikuhi ʻo EIA ua hoʻopilikia ka maloʻo nui a maʻamau ʻole i ka hapa nui o nā wahi o ke komohana o ʻAmelika Hui Pū ʻIa, ʻoiai hoʻi nā mokuʻāina he nui ma ka Pākīpika Komohana ʻĀkau. Aia kēia mau mokuʻāina kahi i loaʻa ai ka hapa nui o ka mana hydropower i hoʻokomo ʻia e ʻAmelika Hui Pū ʻIa. Manaʻo ʻia e alakaʻi kēia i ka emi ʻana o ka hana hydropower ma ʻAmelika Hui Pū ʻIa i kēia makahiki. 14%.
Ua hoʻomaopopo ʻia ma nā mokuʻāina ʻelima o Wakinekona, Idaho, Vermont, Oregon a me South Dakota, ma ka liʻiliʻi he hapalua o ka uila ma kēlā me kēia mokuʻāina mai ka hydropower. I ʻAukake i ka makahiki i hala, ua koi ʻia ʻo Kaleponi, nona ka 13% o ka mana hydropower i hoʻokomo ʻia o ʻAmelika Hui Pū ʻIa, e pani i ke kahua hydropower ʻo Edward Hyatt ma hope o ka hāʻule ʻana o ka wai o Lake Oroville i kahi haʻahaʻa mōʻaukala. Hāʻawi nā tausani o nā ʻohana i ka uila lawa. I Nowemapa i ka makahiki i hala, ua hāʻule ka mana hydropower o Kaleponi i kahi haʻahaʻa 10 makahiki.
ʻO ka Hoover Dam, ke kumu nui o ka hoʻohana ʻana i ka uila ma nā mokuʻāina komohana, ua hoʻonohonoho i ka pae wai haʻahaʻa loa mai kona hoʻopau ʻia ʻana i kēia kauwela, a ua hāʻule kāna hana mana ma 25% a hiki i kēia makahiki.
Eia kekahi, ke hoʻomau nei ka emi ʻana o ka wai o Lake Powell ma ka palena ma waena o Arizona a me Utah. Ua wānana ʻo EIA e alakaʻi kēia i kahi 3% o ka hiki ʻole i ka Glen Canyon Dam ke hoʻoulu i ka uila i kekahi manawa i ka makahiki aʻe, a me kahi 34% o ka hiki ʻole iā ia ke hoʻoulu i ka uila i ka makahiki 2023.Ke piʻi nui nei ke kaomi ma luna o ka pūnaewele mana ʻāpana
ʻO ka emi koke ʻana o ka hana hydropower ua kau i ke kaomi nui ma ka hana o ka pūnaewele mana ʻāpana o ʻAmelika Hui Pū ʻIa. ʻO ka ʻōnaehana pūnaewele o ʻAmelika Hui Pū ʻIa i kēia manawa ua haku ʻia me ʻekolu mau pūnaewele mana nui i hui pū ʻia ma ka hikina, ke komohana, a me ka hema o Texas. Hoʻopili ʻia kēia mau pūnaewele mana ʻekolu i hui pū ʻia e kekahi mau laina DC haʻahaʻa wale nō, e helu ana i 73% a me 19% o ka uila i kūʻai ʻia ma ʻAmelika Hui Pū ʻIa. A me 8%.
I waena o lākou, kokoke ka pūnaewele mana hikina i nā wahi hoʻolako lanahu a me ke kinoea nui ma ʻAmelika Hui Pū ʻIa, a hoʻohana nui i ka lanahu a me ke kinoea kūlohelohe no ka hana mana; kokoke ka pūnaewele mana komohana i nā mauna a me nā muliwai o Colorado, a ua hoʻolaha ʻia me nā mauna pōhaku a me nā mauna ʻē aʻe me ka ʻāina nui, ʻo ia hoʻi ka hydropower. Nui; aia ka pūnaewele mana hema o Texas ma ke kīʻaha kinoea shale, a ʻo ka hana mana kinoea kūlohelohe ka mea nui, e hana ana i kahi pūnaewele mana liʻiliʻi kūʻokoʻa ma ka ʻāina.
Ua kuhikuhi ka pāpāho US CNBC ua hoʻonui hou aku ka pūnaewele mana komohana, ka mea e hilinaʻi nui nei i ka hydropower, i kāna ukana hana. Ua kuhikuhi kekahi poʻe loea e pono koke ana ka Western Power Grid e kū i ka wā e hiki mai ana o ka emi koke ʻana o ka hydropower.
Hōʻike ka ʻikepili EIA ua helu ʻia ka mana hydroelectric ma ka lima o ka ʻōnaehana mana o ʻAmelika Hui Pū ʻIa, a ua hāʻule kona mahele mai 7.25% i ka makahiki i hala a i 6.85%. I ka hapa mua o kēia makahiki, ua hāʻule ka hana mana hydroelectric ma ʻAmelika Hui Pū ʻIa ma 12.6% i kēlā me kēia makahiki.
He mea nui mau ka mana wai
"ʻO ka pilikia nui a mākou e kū nei, ʻo ia ka loaʻa ʻana o kahi kumuwaiwai kūpono a i ʻole ka hui pū ʻana o nā kumuwaiwai e hāʻawi i ka ikehu a me ka mana hoʻopuka mana e like me ka hydropower." Ua ʻōlelo ʻo Lindsay Buckley, ka ʻōlelo a ke Komisina Ikehu o Kaleponi, "Ke alakaʻi nei ka loli o ke aniau i ka wā ʻoi aku ka ʻino. Me ka piʻi pinepine ʻana, pono nā mea lawelawe grid e wikiwiki e hoʻololi i nā loli nui o ka hana mana hydroelectric."
Ua kuhikuhi ʻo EIA he ikehu hou maʻalahi ka hydropower me ka hana ikaika o ka nānā ʻana i nā ukana a me ka hoʻoponopono ʻana, a hiki ke hoʻā a pio maʻalahi. No laila, hiki ke hana maikaʻi me ka makani intermittent a me ka mana makani. I loko o kēia wā, hiki i ka hydropower ke hōʻoluʻolu nui i ka paʻakikī o nā hana grid. ʻO ke ʻano kēia he mea nui mau ka hydropower no ʻAmelika Hui Pū ʻIa.
ʻO Severin Borenstein, he loea ikehu hou ma ke Kulanui o Kaleponi ma Berkeley a he lālā o ka papa alakaʻi o nā mea hoʻokele ʻōnaehana mana kūʻokoʻa o Kaleponi, ua ʻōlelo ʻo ia: "He ʻāpana koʻikoʻi ka hydropower o ka hana hui pū ʻana o ka ʻōnaehana mana holoʻokoʻa, a he mea nui loa kona kūlana."
Ua hōʻike ʻia i kēia manawa, ʻo ka emi koke ʻana o ka hana hydropower ua koi i nā ʻoihana lawelawe lehulehu a me nā mea lawelawe grid mokuʻāina ma nā mokuʻāina komohana he nui o ʻAmelika Hui Pū ʻIa e ʻimi i nā kumu hana mana ʻē aʻe, e like me nā wahie fossil, ka mana nukelea, a me ka makani a me ka mana lā. "ʻO kēia ke alakaʻi pololei ʻole nei i nā kumukūʻai hana kiʻekiʻe no nā lawelawe." Ua ʻōlelo pololei ʻo Nathalie Voisin, he ʻenekinia waiwai wai o Los Angeles. "He hilinaʻi loa ka hydropower i ka wā mua, akā ʻo ke kūlana o kēia manawa ke koi nei iā mākou e ʻimi i kahi hopena i ka hikiwawe loa."
