Pūnaha Tohatoha Pūngao Ā-Wharewha mō te Whakamahana Wāhi
He rauemi pūngao tino whai hua, he rauemi pūngao hoki te pūngao waiariki. I ahu mai tēnei pūngao i te wera e rongoa ana i roto i te whenua, ā, ka taea te whakamahi mō ngā kaupapa maha, tae atu ki te whakamahana i te wāhi. I roto i ētahi whenua he nui ngā mahi waiariki, pērā i a Iceland me Aotearoa, kua noho te whakamahi i te pūngao waiariki mō te whakamahana i te wāhi, ā, kua kitea tōna whai huatanga. Ka matapakihia e tēnei tuhinga te mahi a te pūnaha tohatoha pūngao waiariki mō te whakamahana i te wāhi, ōna painga, me ngā wero e pā ana ki tōna whakatinanatanga.
Ngā Mātāpono Taketake o te Pūngao Pūngao Taiao
Ka ahu mai te pūngao waiariki i te pūtake wera o te Ao. Ka taea e tēnei wera te tae atu ki te mata mā roto i ngā āhuatanga taiao pēnei i ngā geyser me ngā puna wera, mā roto rānei i te keri me te hangarau tango wera mai i ngā puna waiariki. Kātahi ka taea te whakamahi tika i te wera ka puta hei whakamahana, hei huri rānei hei hiko.
I roto i te horopaki o te whakamahana wāhi, e rua ngā pūnaha matua e whiwhihia ai te pūngao waiariki: ngā pūnaha waiariki whakamahi tika me ngā papu wera waiariki.
Pūnaha Pūnaha Ā-Wharewera Tika
Ko ngā pūnaha waiariki tika tētahi o ngā huarahi tawhito rawa atu, māmā rawa atu hoki ki te whakamahi i te pūngao waiariki. I roto i tēnei pūnaha, ka tangohia te wai wera mai i raro i te whenua, ka tukuna tika atu ki ngā whare hei whakamahana. He tino whai hua tēnei tikanga i ngā wāhi he nui ngā puna wai wera taiao. Ka taea te whakamahi i ēnei pūnaha mō te whakamahana wāhi, te whakamahana wai, tae noa ki te ahuwhenua me te ahumahi.
Ko tētahi tauira tūturu o tēnei pūnaha ko te whakamahinga o te wai wera whenua i Iceland. I reira, neke atu i te 90% o ngā whare e whakamahi ana i te pūngao whenua mō te whakamahana me te wai.
Papu Wera Ā-whenua
He hangarau matatau ake ngā papu wera whenua, ā, ka taea te whakamahi i ngā wāhi maha, tae atu ki ngā wāhi kāore he pūtake wera whenua tūturu kaha. He rite tonu te mahi a ngā papu wera whenua ki ngā papu wera tuku iho, engari e whakamahi ana i te wera whenua hei pūtake hiko. Ko te pūnaha he paipa i whakatakotoria ki raro i te whenua (i roto i ngā toka, i ngā poka keri rānei) kei reira ngā pāmahana e pumau ana puta noa i te tau. Ka whakakīia ēnei paipa ki te wai e mimiti ana i te wera mai i te whenua i te takurua, ā, ka tukuna ki te whenua i te raumati.
Te Tukanga Mahi o te Pūnaha Whakawera Geothermal
He maha ngā mahi māmā engari he nui e mahia ana e ngā pūnaha whakamahana wāhi e ahu mai ana i te pūngao waiariki.
1. Kohikohi Wera: Ina whakamahia he pūnaha papu wera whenua, ka mimitihia te wera mai i te whenua e ngā paipa kua tanumia ki raro i te whenua. Ka taea te whakarite i ēnei paipa kia whakapae, kia poutū rānei, i runga i te āhua o te oneone me ngā hiahia motuhake.
2. Whakawhiti Wera: Ka haria te wera e te wai i roto i ngā paipa mai i te whenua, ka tukuna ki te papu wera i runga ake i te taumata whenua. Kātahi ka whakanuia e te papu wera te pāmahana o tēnei wai ina hiahiatia.
3. Te Tohatoha Wera: Kātahi ka tohatohahia te wera e puta ana ki te pūnaha whakamahana o te whare, mā roto i ngā paipa, i ngā whakamahana rānei.
4. Huringa Whakahoki: Ka hoki te wai kua tukuna tōna wera ki te whenua hei tīmata anō i te huringa whakamahana.
Ngā Painga o ngā Pūnaha Pūngao Ā-Wharewhenua
He maha ngā painga nui o te whakamahi i te pūngao geothermal mō te whakamahana wāhi.
Teitei o te Pūngao Whai Hua
He tino whai hua ngā pūnaha pūngao waiariki, inā koa ko ērā e whakamahi ana i ngā papu wera waiariki. Ka taea e rātou te whakaiti i te whakamahinga pūngao tae atu ki te 70% ki te whakaritea ki ngā pūnaha whakamahana tuku iho. Nā te mea ka whakamahia noa e ngā pūnaha te pūngao e wātea ana mai i te whenua, kaua ki te whakaputa wera hou mai i ngā wahie pūmua.
He pai mō te taiao
He pūtake pūngao whakahou te pūngao waiariki, ā, kāore e nui ngā tukunga hau kati kōtuhi e puta mai ana. Nō reira, ka āwhina tōna whakamahinga ki te whakaiti i te tapuwae waro, ā, ka whai wāhi hoki ki te whakaiti i te huringa āhuarangi. Nā te mea i ahu mai te pūtake pūngao i te wera tūturu o Papatūānuku, kāore he tahunga o ngā wahie pūmua, arā, kāore he tukunga o te hauhā waro, o ētahi atu poke rānei.
Te Wātea me te Manawanui
E wātea ana te pūngao waiariki i te tau katoa, ā, kāore e whakawhirinaki ki ngā āhuatanga o te rangi, he rerekē ki te pūngao o te rā, o te hau rānei. Nā tēnei ka waiho hei puna pūngao pono, pumau hoki mō te whakamahana i te wāhi.
Ngā Utu Whakahaere Iti
Ahakoa he nui pea ngā utu tāutanga tuatahi mō tētahi pūnaha waiariki, he tino iti ngā utu whakahaere mō te wā roa. Nā te mea he iti noa te hiko e hiahiatia ana e te pūnaha hei whakahaere i te papu wera, ā, he iti noa hoki te tiaki e hiahiatia ana.
Ngā Wero me ngā Ārai
Ahakoa ōna painga maha, he maha ngā wero kei te whakatinana i ngā pūnaha pūngao waiariki mō te whakamahana wāhi.
Ngā Utu Tīmatanga Teitei
Ko tētahi o ngā arai nui ko te nui o ngā utu tāutanga tuatahi. Me nui te haumitanga hei tāuta i ngā pūnaha paipa me ngā papu wera i raro i te whenua. Heoi, he maha ngā wā ka ea tēnei i te whai huatanga o te pūngao mō te wā roa me te penapena utu whakahaere.
Ngā Herenga Whenua
Ko te whai huatanga o te pūngao waiariki e whakawhirinaki ana ki te tauwāhi matawhenua. Tērā pea me keri hohonu ake ngā wāhi he iti te mahi waiariki, ā, ka piki ake ngā utu.
Te Tirohanga me te Mātauranga
Mā te kore o ngā mōhiotanga me te māramatanga mō ngā painga me te mahi a ngā pūnaha pūngao waiariki ka ārai i te whakaurunga o tēnei hangarau. Me whai kaupapa mātauranga me te whakamōhiotanga kia whānui ake ai te whakaae a te marea.
Ngā Ture me ngā Kaupapa Here
I runga i te whenua me te rohe, ka pā pea ngā ture me ngā kaupapa here a te kāwanatanga ki te whakatinanatanga o ngā pūnaha waiariki. Tērā pea ka hiahiatia he whakaaetanga motuhake mō te keri, te whakamahi rānei i ngā rauemi waiariki i ētahi rohe.
Whakamutunga
He otinga whai hua, he pai hoki mō te taiao ngā pūnaha tohatoha pūngao waiariki mō te whakamahana wāhi, ka taea te whakaiti i te whakawhirinaki ki ngā wahie pūmua me ngā tukunga hau kati kōtuhi. Ahakoa he uaua ki a rātou te whakamahi i ngā utu tāutanga tuatahi me ngā herenga ā-rohe, ko ngā painga roa o te whai huatanga o te pūngao me te whakaiti i ngā utu whakahaere ka waiho hei kōwhiringa pai mō te tini. Mā te mātauranga tūmatanui, te tautoko kaupapa here, me te auahatanga hangarau ka whakapakari ake i te tūranga o te pūngao waiariki i roto i ngā pūnaha whakamahana ā muri ake nei.
I tēnei ao e rapu tonu ana i ngā otinga pūngao tauwhiro, he taahiraa whakamua tēnei hei whakaaroaro māu mō te whakamahi i te pūngao waiariki hei whakamahana i te wāhi. Mēnā he hangarau tika, he tautoko rawaka hoki, ka taea e te pūngao waiariki te noho hei pou matua mō tētahi pūnaha pūngao ā-ao matomato, whai hua hoki.
