Ka hopena o ka hale ʻōmaʻomaʻo
ʻO nā nalu infrared, ʻike ʻia, a me UV e hōʻea i ka Honua e komo i kahi kaʻina hana e hoʻomehana ai i ka honua a hiki i ke ola ke ola-ʻo ia ka mea i kapa ʻia ʻo "ka hopena hale."

Ma kahi o 30 pākēneka o ka ikehu o ka lā i hiki i ka Honua e ʻike hou ʻia i ka lewa.Hoʻokomo ʻia ke koena i ka lewa o ka Honua.Hoʻomaʻamaʻa ka radiation i ka ʻili o ka Honua, a hoʻihoʻi ka ʻili i kekahi o ka ikehu ma ke ʻano o nā nalu infrared.Ke piʻi aʻe lākou ma ka lewa, hoʻopaʻa ʻia lākou e nā kinoea ʻōmaʻomaʻo, e like me ka mahu wai a me ka carbon dioxide.

Hoʻopaʻa nā kinoea hale ʻōmaʻomaʻo i ka wela e hoʻi hou ana i ka lewa.Ma kēia ʻano, hana lākou e like me nā paia aniani o kahi hale ʻōmaʻomaʻo.Mālama kēia hopena ʻōmaʻomaʻo i ka mahana o ka Honua e mālama i ke ola.

Aneane pau ke ola o ka Honua e hilinaʻi i ka ikehu o ka lā no ka ʻai, ma ke ʻano pololei a i ʻole.

Ke hilinaʻi pololei nei nā mea hana i ka ikehu lā.Hoʻopili lākou i ka lā a hoʻololi i nā meaʻai ma o ke kaʻina i kapa ʻia ʻo photosynthesis.ʻO nā mea hana, i kapa ʻia hoʻi he autotrophs, nā mea kanu, nā algae, bacteria, a me nā haʻi.ʻO Autotrophs ke kumu o ka pūnaewele meaʻai.

Ke hilinaʻi nei nā mea kūʻai aku i nā mea hana no nā meaʻai.ʻO nā herbivores, carnivores, omnivores, a me nā detritivores e hilinaʻi ʻole i ka ikehu lā.ʻAi nā herbivores i nā mea kanu a me nā mea hana ʻē aʻe.ʻAi nā carnivores a me nā omnivores i nā mea hana a me nā herbivores.Hoʻopau nā Detritivores i nā mea kanu a me nā holoholona ma ka ʻai ʻana.

ʻO Photosynthesis kekahi kuleana no nā wahie mōʻalihaku āpau ma ka Honua.Manaʻo ka poʻe ʻepekema ma kahi o ʻekolu piliona makahiki i hala aku nei, ua ulu nā autotroph mua i loko o ka wai.ʻAe ka lā i ke ola o nā mea kanu e ulu a ulu.Ma hope o ka make ʻana o nā autotrophs, decomposed a neʻe hohonu i ka Honua, i kekahi manawa he mau kaukani mika.Ua hoʻomau kēia hana no nā miliona mau makahiki.

Ma lalo o ke kaomi ikaika a me nā wela kiʻekiʻe, ua lilo kēia mau koena i mea a mākou i ʻike ai he wahie fossil.Ua lilo nā microorganisms i ka aila, ke kinoea maoli, a me ka lanahu.

Ua hoʻomohala nā kānaka i nā kaʻina hana no ka unuhi ʻana i kēia mau wahie fossil a hoʻohana iā lākou no ka ikehu.Eia naʻe, ʻo nā wahie mōʻalihaku he kumu waiwai hiki ʻole ke hoʻololi ʻia.Lawe lākou i nā miliona makahiki e hana ai.

Hoʻohana ʻana i ka ikehu lā

ʻO ka ikehu o ka lā he kumu waiwai hou, a hiki i nā ʻenehana he nui ke hōʻiliʻili pololei ia no ka hoʻohana ʻana i nā hale, nā ʻoihana, nā kula, a me nā halemai.ʻO kekahi o nā ʻenehana ikehu lā e pili ana i nā pūnaewele photovoltaic a me nā panela, ka ikehu solar concentrated, a me ka hoʻolālā lā.

Aia nā ʻano like ʻole o ka hopu ʻana i ka pāhawewe lā a hoʻololi iā ia i ikehu hoʻohana.Hoʻohana nā ʻano hana i ka ikehu lā hana a i ʻole ka ikehu solar passive.

Photovoltaics

ʻO Photovoltaics kahi ʻano o ka ʻenehana solar ikaika i ʻike ʻia i ka makahiki 1839 e ka physicist Farani 19 makahiki ʻo Alexandre-Edmond Becquerel.Ua ʻike ʻo Becquerel i ka wā i hoʻokomo ai ʻo ia i ke kala-chloride i loko o kahi waiʻawaʻawa a hōʻike ʻia i ka lā, ua hana nā electrodes platinum i hoʻopili ʻia me ia.ʻO kēia kaʻina hana o ka hoʻoulu ʻana i ka uila mai ka pāhawewe lā i kapa ʻia ka hopena photovoltaic, a i ʻole photovoltaics.

I kēia mau lā, ʻo ka photovoltaics ke ala maʻa loa e hoʻohana i ka ikehu lā.Hoʻokomo pinepine nā kiʻi kiʻi kiʻi kiʻi i nā paneli lā, kahi hōʻiliʻili o nā kakini a i ʻole mau haneli o nā cell solar.

Loaʻa i kēlā me kēia cell solar kahi semiconductor, maʻamau i hana ʻia me ke silika.Ke komo ka semiconductor i ka lā, hoʻokuʻu ia i nā electrons.Ke alakaʻi nei ke kahua uila i kēia mau electrons wehe i loko o ke au uila, e kahe ana ma kahi ʻaoʻao.ʻO nā mea pili metala ma luna a ma lalo o kahi pūnaewele lā e kuhikuhi i kēlā ʻano i kahi mea waho.Hiki i ka mea waho ke liʻiliʻi e like me ka calculator solar a i ʻole ka nui e like me ka mana mana.

Ua hoʻohana nui ʻia ka Photovoltaics ma luna o nā mokulele.Nui nā satelite, me ka International Space Station (ISS), e hōʻike ana i nā "'ēheu" ākea o nā paneli lā.He ʻelua ʻēheu lā (SAW) ko ka ISS, e hoʻohana ana kēlā me kēia ma kahi o 33,000 mau ʻēheu solar.Hāʻawi kēia mau pūnaewele photovoltaic i ka uila a pau i ka ISS, e ʻae ana i nā astronauts e hoʻokele i ke kahua, e noho maluhia ma ka lewa no nā mahina i ka manawa, a hana i nā hoʻokolohua ʻepekema a me ka ʻenekinia.

Ua kūkulu ʻia nā kikowaena mana photovoltaic ma ka honua holoʻokoʻa.Aia nā kikowaena nui ma United States, India, a me Kina.Hoʻopuka kēia mau mana mana he mau haneli megawatts o ka uila, hoʻohana ʻia e hoʻolako i nā hale, nā ʻoihana, nā kula, a me nā halemai.

Hiki ke hoʻokomo ʻia ka ʻenehana Photovoltaic ma kahi ʻano liʻiliʻi.Hiki ke hoʻopaʻa ʻia nā panela a me nā cell i nā hale a i ʻole nā ​​paia o waho o nā hale, e hāʻawi ana i ka uila no ka hale.Hiki ke hoonoho ia lakou ma na alanui a hiki i na alanui malamalama.He liʻiliʻi nā pūnaewele lā no ka hoʻohana ʻana i nā mea ʻoi aku ka liʻiliʻi, e like me nā calculators, nā mika kaʻa, nā mea hoʻopaʻa ʻōpala, a me nā pamu wai.

ʻO ka ikehu o ka lā

ʻO kekahi ʻano o ka ʻenehana lā ikaika ʻo ia ka ikehu solar concentrated solar power (CSP).Hoʻohana ka ʻenehana CSP i nā lens a me nā aniani no ka nānā ʻana i ka lā mai kahi ākea a i kahi wahi liʻiliʻi loa.Hoʻomaʻamaʻa kēia wahi ikaika o ka radiation i kahi wai, a laila e hoʻohua ai i ka uila a i ʻole ka hoʻoulu ʻana i kahi hana ʻē aʻe.

ʻO nā kapuahi lā he laʻana o ka mana solar concentrated.Nui nā ʻano umu ahi o ka lā, me nā hale kiaʻi mana o ka lā, nā pā parabolic, a me nā mea hōʻike Fresnel.Hoʻohana lākou i ke ʻano maʻamau like e hopu a hoʻololi i ka ikehu.

Hoʻohana nā hale kiaʻi mana o ka lā i nā heliostats, nā aniani palahalaha e huli ana e hahai i ka ʻaʻa o ka lā ma ka lewa.Hoʻonohonoho ʻia nā aniani a puni kahi "hale kiaʻi ʻohi" waena, a e hoʻomālamalama i ka lā i kahi kukuna o ka mālamalama e ʻā ana ma kahi kiko o ka hale kiaʻi.

Ma nā hoʻolālā mua o nā hale kiaʻi mana o ka lā, ua hoʻomehana ka lā i kahi pahu wai, kahi i hoʻohua ai ka mahu e hoʻoikaika ai i ka turbine.I kēia mau lā, hoʻohana kekahi mau hale kiaʻi mana o ka lā i ka sodium wai, ʻoi aku ka nui o ka wela a mālama i ka wela no kahi manawa lōʻihi.'O ia ho'i, 'a'ole hiki wale ka wai i ka wela o 773 a hiki i 1,273K (500° a hiki i 1,000° C a i 'ole 932° a hiki i 1,832° F), akā hiki ke ho'omau i ka ho'olapalapa 'ana i ka wai a ho'oulu i ka mana oiai 'a'ole alohilohi ka lā.

Hoʻohana ʻia nā pahu Parabolic a me Fresnel reflectors CSP, akā ʻokoʻa ke ʻano o kā lākou mau aniani.ʻO nā aniani parabolic ua ʻōwili ʻia, me ke ʻano like me kahi noho.Hoʻohana nā mea hoʻomanaʻo Fresnel i nā ʻāpana aniani ākea a lahilahi e hopu i ka lā a kuhikuhi iā ia ma luna o kahi paipu wai.ʻOi aku ka ʻāpana o ka ʻili o nā mea hoʻohālikelike Fresnel ma mua o nā pā parabolic a hiki ke hoʻopaʻa i ka ikehu o ka lā ma kahi o 30 mau manawa o kona ikaika maʻamau.

Ua kūkulu mua ʻia nā mea kanu mana solar concentrated i nā makahiki 1980.ʻO ka hale nui loa ma ka honua he pūʻulu o nā mea kanu ma Mojave Desert ma ka mokuʻāina ʻo US o Kaleponi.ʻO kēia Solar Energy Generating System (SEGS) e hoʻopuka ana ma mua o 650 gigawatt-hola o ka uila i kēlā me kēia makahiki.Ua kūkulu ʻia nā mea kanu nui a maikaʻi ʻē aʻe ma Sepania a me India.

Hiki ke hoʻohana ʻia ka mana solar concentrated ma kahi ʻano liʻiliʻi.Hiki iā ia ke hana i ka wela no nā mea kuke lā, no ka laʻana.Hoʻohana ka poʻe ma nā kauhale a puni ka honua i nā mea kuke lā e hoʻolapalapa ai i ka wai no ka hoʻomaʻemaʻe ʻana a me ka kuke ʻana i ka meaʻai.

Hāʻawi nā mea kuke o ka lā i nā mea maikaʻi ma mua o nā kapuahi ahi: ʻAʻole ia he ahi, ʻaʻole hana i ka uahi, ʻaʻole koi i ka wahie, a hoʻemi i ka nalowale o ka noho ʻana ma nā ululāʻau kahi e ʻohi ʻia ai nā kumulāʻau no ka wahie.Hiki i nā mea kuke o ka lā ke ʻae i nā kamaʻāina e ʻimi i ka manawa no ka hoʻonaʻauao, ʻoihana, olakino, a ʻohana paha i ka manawa i hoʻohana mua ʻia no ka ʻohi wahie.Hoʻohana ʻia nā mea kuke lā ma nā wahi like ʻole e like me Chad, Israel, India, a me Peru.

Hoʻolālā Lā

I loko o ka lā holoʻokoʻa, ʻo ka ikehu o ka lā kekahi ʻāpana o ke kaʻina hana o ka convection wela, a i ʻole ka neʻe ʻana o ka wela mai kahi wahi mahana a i kahi mahana.Ke piʻi aʻe ka lā, hoʻomaka ʻo ia e pumehana i nā mea a me nā mea ma ka Honua.I ka lā holoʻokoʻa, hoʻopale kēia mau mea i ka wela mai ka pāhawewe lā.I ka pō, i ka napoʻo ʻana o ka lā a maʻalili ka lewa, hoʻokuʻu hou nā mea i ko lākou wela i ka lewa.

Hoʻohana pono nā ʻenehana ikehu lā passive i kēia kaʻina hana hoʻomehana kūlohelohe a me ka hoʻoilo.

Hoʻohana nā hale a me nā hale ʻē aʻe i ka ikehu solar passive e puʻunaue i ka wela me ka maikaʻi a me ke kumukūʻai.ʻO ka helu ʻana i ka "thermal mass" o kahi hale kahi laʻana o kēia.ʻO ka nui wela o ka hale ka nui o nā mea wela i ka lā.ʻO nā laʻana o ka nui wela o ka hale he lāʻau, metala, kekona, pālolo, pōhaku, a i ʻole ka lepo.I ka pō, hoʻokuʻu hou ka wela wela i loko o ka lumi.ʻO nā ʻōnaehana hoʻoheheʻe maikaʻi - nā alaloa, nā puka makani, a me nā ʻauwaʻa ea - e puʻunaue i ka ea mehana a mālama i kahi mahana maʻemaʻe o loko.

Hoʻokomo pinepine ʻia ka ʻenehana solar passive i ka hoʻolālā ʻana o kahi hale.No ka laʻana, i ka pae hoʻolālā o ke kūkulu ʻana, hiki i ka ʻenekinia a i ʻole ka mea hana hale ke hoʻohālikelike i ka hale me ke ala o ka lā i kēlā me kēia lā e loaʻa ai ka nui o ka lā.E noʻonoʻo ana kēia ʻano i ka latitu, ke kiʻekiʻe, a me ka uhi ao maʻamau o kekahi wahi kikoʻī.Eia hou, hiki ke kūkulu ʻia a hoʻopaʻa hou ʻia paha nā hale e loaʻa i ka insulation thermal, thermal mass, a i ʻole ka malu keu.

ʻO nā hiʻohiʻona ʻē aʻe o ka hoʻolālā solar passive he mau hale ʻoluʻolu, nā pale ʻālohilohi, a me nā hale ʻōmaʻomaʻo.Ua pena ʻia nā hale maʻalili i ke keʻokeʻo, a e hōʻike ana i ka radiation o ka lā ma mua o ke komo ʻana.ʻO kaʻili keʻokeʻo e hoʻemi i ka nui o ka wela e hiki ai i loko o ka hale, aʻo ia hoʻi ka emiʻana o ka ikehu e pono ai e hoʻomaha i ka hale.

Hana like nā pale kukui me nā hale anuanu.Hāʻawi lākou i ka insulation me nā mea noʻonoʻo nui, e like me ka alumini alumini.Hōʻike ka foil, ma kahi o ka hoʻopili ʻana, wela, a hiki ke hoʻemi i nā kumukūʻai hoʻomaha a hiki i 10 pakeneka.Ma waho aʻe o nā hale a me nā attics, hiki ke hoʻokomo ʻia nā pale kukui ma lalo o nā papahele.

ʻO nā kaupaku ʻōmaʻomaʻo he mau hale i uhi ʻia me nā mea kanu.Pono lākou i ka lepo a me ka irrigation e kākoʻo i nā mea kanu, a me kahi papa wai ma lalo.ʻAʻole hoʻemi wale nā ​​hale ʻōmaʻomaʻo i ka nui o ka wela i komo a nalowale, akā hāʻawi pū kekahi i nā mea kanu.Ma o photosynthesis, hoʻopaʻa nā mea kanu ma luna o nā hale ʻōmaʻomaʻo i ka carbon dioxide a hoʻokuʻu i ka oxygen.Kānā lākou i nā mea haumia mai ka ua a me ka ea, a hoʻopau i kekahi o nā hopena o ka hoʻohana ʻana i ka ikehu ma ia wahi.

He kuʻuna nā hale ʻōmaʻomaʻo ma Scandinavia no nā kenekulia, a ua lilo i mea kaulana loa ma Australia, Western Europe, Canada, a me ʻAmelika Hui Pū ʻIa.No ka laʻana, ua uhi ka Ford Motor Company i 42,000 square meters (450,000 square feet) o kona mau hale kanu hui ma Dearborn, Michigan, me nā mea kanu.Ma waho aʻe o ka hōʻemi ʻana i ka hoʻokuʻu ʻia ʻana o ke kinoea ʻōmaʻomaʻo, hoʻemi nā hale i ka kahe o ka ʻino ma o ka lawe ʻana i kekahi mau kenimika o ka ua.

Hiki i nā hale ʻōmaʻomaʻo a me nā hale ʻoluʻolu ke kūʻē i ka hopena "moku wela o ke kūlanakauhale".Ma nā kūlanakauhale paʻa, hiki ke piʻi aʻe ka mahana ma mua o nā wahi a puni.Nui nā kumu i kēia: Ua hana ʻia nā kūlanakauhale me nā mea e like me ka asphalt a me ke kaila e hoʻomoʻa i ka wela;ʻO nā hale kiʻekiʻe e pale ana i ka makani a me kona hopena hoʻomaha;a ʻo ka nui o ka wela ʻōpala e hana ʻia e ka ʻoihana, kaʻa kaʻa, a me nā heluna kiʻekiʻe.Me ka hoʻohana ʻana i ka wahi i loaʻa ma luna o ka hale e kanu i nā kumulāʻau, a i ʻole ka hoʻohālikelike ʻana i ka wela me nā hale keʻokeʻo, hiki ke hoʻohaʻahaʻa iki i ka piʻi ʻana o ka wela o ke kaona ma nā kūlanakauhale.

Energy Solar a me nā kānaka

No ka mea, ʻalohi wale ka lā ma kahi o ka hapalua o ka lā ma ka hapa nui o ka honua, pono e hoʻokomo nā ʻenehana ikehu lā i nā ʻano o ka mālama ʻana i ka ikehu i nā hola pōuliuli.

Hoʻohana nā ʻōnaehana nui wela i ka paraffin wax a i ʻole nā ​​ʻano paʻakai like ʻole e mālama i ka ikehu ma ke ʻano o ka wela.Hiki i nā ʻōnaehana Photovoltaic ke hoʻouna i ka uila keu aku i ka pahu mana kūloko, a i ʻole e mālama i ka ikehu i loko o nā ʻaniani rechargeable.

Nui nā pono a me nā pōʻino o ka hoʻohana ʻana i ka ikehu lā.

Nā pono
ʻO kahi pōmaikaʻi nui i ka hoʻohana ʻana i ka ikehu lā, ʻo ia kahi kumu waiwai hou.E loaʻa iā mākou kahi lako paʻa, palena ʻole o ka lā no ʻelima mau piliona makahiki.I loko o hoʻokahi hola, loaʻa ka lewa o ka Honua i ka lā e lawa ai ka pono o ka uila o kēlā me kēia kanaka ma ka Honua no hoʻokahi makahiki.

Maʻemaʻe ka ikehu lā.Ma hope o ka hana ʻana a hoʻokomo ʻia nā mea hana ʻenehana solar, ʻaʻole pono ka ikehu lā i ka wahie e hana ai.ʻAʻole ia e hoʻokuʻu i nā kinoea ʻōmaʻomaʻo a i ʻole nā ​​​​mea ʻona.ʻO ka hoʻohana ʻana i ka ikehu lā hiki ke hōʻemi nui i ka hopena i loaʻa iā mākou ma ke kaiapuni.

Aia nā wahi e hoʻohana ai ka ikehu lā.Loaʻa i nā hale a me nā hale ma nā wahi me ka nui o ka lā a me ka uhi ao haʻahaʻa ka manawa e hoʻohana ai i ka ikehu nui o ka lā.

Hāʻawi nā mea kuke o ka lā i kahi koho maikaʻi loa i ka kuke ʻana me nā kapuahi ahi i puhi ʻia i ka lāʻau - kahi e hilinaʻi mau ai ʻelua piliona kānaka.Hāʻawi nā mea kuke o ka lā i kahi ala maʻemaʻe a palekana e hoʻomaʻemaʻe i ka wai a kuke i ka meaʻai.

Hoʻopiha ka ikehu o ka lā i nā kumuwaiwai hou aʻe, e like me ka makani a i ʻole ka ikehu hydroelectric.

Hiki i nā hale a i ʻole nā ​​ʻoihana e hoʻokomo ana i nā panela solar kūleʻa ke hana maoli i ka uila.Hiki i kēia mau mea hale a mea ʻoihana paha ke kūʻai aku i ka ikehu i ka mea hoʻolako uila, e hōʻemi a hoʻopau paha i nā bila mana.

Nā pōʻino
ʻO ka mea pale nui i ka hoʻohana ʻana i ka ikehu o ka lā ʻo ia ka mea pono.He pipiʻi nā lako ʻenehana solar.ʻO ke kūʻai ʻana a me ka hoʻokomo ʻana i nā mea hana hiki ke lilo i ʻumi kaukani kālā no nā hale pākahi.ʻOiai ke hāʻawi pinepine nei ke aupuni i nā ʻauhau hoʻemi i ka poʻe a me nā ʻoihana e hoʻohana ana i ka ikehu lā, a hiki i ka ʻenehana ke hoʻopau i nā bila uila, ʻoi aku ka kiʻekiʻe o ke kumu kūʻai mua no nā mea he nui e noʻonoʻo.

He kaumaha nō hoʻi nā mea hana ikehu lā.No ka hoʻihoʻi hou ʻana a i ʻole ke kau ʻana i nā panela lā ma luna o ka hale, pono ka hale e ikaika, nui, a e kū pono i ke ala o ka lā.

ʻO ka ʻenehana ikaika a me ka passive solar e pili ana i nā mea i waho o kā mākou mana, e like me ke aniau a me ka uhi ao.Pono e aʻo ʻia nā wahi kūloko no ka hoʻoholo ʻana i ka mana o ka lā ma ia wahi.

Pono e nui ka malamalama o ka lā i mea e pono ai ka ikehu o ka lā.Ma ka hapanui o nā wahi o ka Honua, ʻo ka ʻokoʻa o ka lā ka mea paʻakikī ke hoʻokō ma ke ʻano he kumu hoʻokahi o ka ikehu.
