Ma muli o kona ductility maikaʻi loa, thermal conductivity a me ka conductivity, hoʻohana nui ʻia ke keleawe i nā ʻoihana like ʻole, ka mea nui i ka mana, kūkulu hale, nā mea hana hale, ka halihali a me nā ʻoihana ʻē aʻe.

I ka ʻoihana mana, ʻo ke keleawe ka mea kūpono loa i ka mea metala waiwai ʻole e like me ke alakaʻi.He kiʻekiʻe loa ke koi no ke keleawe i nā uea a me nā kaula i ka ʻoihana mana.I ka ʻoihana mea hana hale, hoʻohana ʻia ke keleawe i nā condensers a me nā paipu hoʻoheheʻe wela o nā friji, air conditioners a me nā mea pono hale ʻē aʻe.

I ka ʻoihana kūkulu, hoʻohana nui ʻia nā paipu keleawe i ke kūkulu ʻana i nā radiators, nā ʻōnaehana gas a me nā lako wai a me nā ʻōnaehana wai.I ka ʻoihana halihali, hoʻohana ʻia ke keleawe a me ke keleawe no nā moku, kaʻa a me nā mea mokulele.

Eia kekahi, hoʻohana ʻia ka nui o ke keleawe i ka ʻōnaehana kaapuni o nā mea lawe.I waena o lākou, ʻo ka ʻoihana mana ka ʻoihana me ka hoʻohana keleawe nui loa ma Kina, ʻo 46% ka nui o ka hoʻohana ʻana, ukali ʻia e ke kūkulu ʻana, nā mea hana hale a me ka halihali.
