E pili ana i ke kaʻina hana o ka hoʻololi ʻana i ka hydropower, ka wahie mōʻalihaku (kohu, aila, kinoea maoli) ikehu wela, ikehu nuklea, ikehu lā, ikehu makani, ikehu geothermal, ikehu moana, etc. kapa ʻia ka hana mana.Hoʻohana ʻia e hoʻolako i nā pono o nā ʻāpana like ʻole o ka hoʻokele waiwai a me ke ola o nā kānaka.Hoʻokaʻawale ʻia nā mea hana mana i loko o nā hoʻonohonoho mana wela, nā ʻenehana hydropower, nā mana nuklea a me nā mea hana mana ikehu e like me ke ʻano o ka ikehu.ʻO ka hale mana wela, aia nā pahu pahu mana, nā turbine mahu, nā mea hana (i kapa mau ʻia ʻo nā ʻenekini nui ʻekolu) a me kā lākou mau mea kōkua.Aia i loko o ka hale mana hydroelectric kahi hoʻonohonoho wai turbine generator, kahi kiaʻāina, kahi mea hydraulic a me nā mea kōkua ʻē aʻe.Aia i loko o ka hale mana nukili kahi reactor nuklea, kahi mea hoʻoheheʻe mahu, kahi pahu turbine hoʻonohonoho a me nā mea kōkua ʻē aʻe.ʻOi aku ka maʻalahi o ka ikehu uila ma mua o nā kumu ikehu ʻē aʻe i ka hana ʻana, hoʻoili a hoʻohana.No laila, he kumu ikehu lua ia.ʻO ka hana mana ma ke kikowaena o ka ʻoihana mana, ka mea e hoʻoholo ai i ka nui o ka ʻoihana mana a pili pū i ka hoʻomohala ʻana o ka hoʻoili ʻana, hoʻololi, a me ka hāʻawi ʻana i ka ʻōnaehana mana.I ka pau ʻana o nā makahiki 1980, ʻo nā ʻano nui o ka hoʻomohala mana ʻo ia ka mana wela, ka mana wai a me ka mana nuklea, a ʻo nā hanauna ʻekolu i ʻoi aku ma mua o 99% o ka nui o ka mana.Ma muli o ka hopena o ka lanahu, ka aila, nā kumuwaiwai kūlohelohe a me ka pollution kaiapuni, ua hāʻule ka hapa o ka mana wela ma ka honua mai kahi o 70% a i kahi 64% i nā makahiki 1980;Ua aneane hoʻomohala ʻia ka hydropower ma muli o nā kumu wai i hoʻomohala ʻia e ka ʻoihana.90%, no laila e mālama ʻia ka māhele ma kahi o 20%;ke piʻi aʻe nei ka hapa o ka mana nuklea, a ma ka hopena o 1980, ua ʻoi aku ia ma mua o 15%.Hōʻike kēia me ka nele o nā wahie fossil, e uku nui ʻia ka mana nuklea.
