E toru ngā wāhanga whanaketanga o ngā mīhini pēhi hau i tōku whenua.

Ko te wāhanga tuatahi ko te wā o ngā pūwero piston.I mua i te tau 1999, ko ngā hua pūwero matua i te mākete o tōku whenua ko ngā pūwero piston, ā, kāore i te tino mārama ngā umanga o muri mai kingā pūwhakakoi tīwiri, ā, kāore i nui te tono. I tēnei wā, ko ngā kamupene o tāwāhi me te kaha whakaputa o ngā pūwero tīwiri he kamupene o tāwāhi te nuinga, tae atu ki a Atlas, Ingersoll Rand me Sullair me ētahi atu waitohu o tāwāhi e noho ana i te tūranga kotahi i roto i te mākete pūwero hau tīwiri.

Ko te wāhanga tuarua ko te wā o ngā compressors tīwiri tikanga(2000-2010). Whai muri i te tau 2000, i te wā i uru ai te ōhanga o tōku whenua ki tētahi wā tipu tere, nā te tere o te whanaketanga o te umanga whakatō o ngā pūwero tīwiri i hua ake ai te pikinga nui o te tono mō ngā pūwero tīwiri ā-rohe, ā, i tino kaha te hoko o ngā pūwero tīwiri. Ngā kaihanga pūwero tīwiri,pūwhakakoi tīwirikua uru ngā kaihanga ki tētahi wā whanaketanga tere.

Ko te tuatoru o ngā wāhanga ko te wā o ngā tauira teitei o ngā pūwero tīwiri(mai i te tau 2011 ki nāianei). Whai muri i te tau 2011, kua puhoi te tipu ōhanga o tōku whenua, ā, kua puhoi hoki te tere tipu o te mākete pūwero tīwiri. Nā te nui o ngā kaihanga pūwero iti kua kaha ake te whakataetae i roto i te mākete. I te tīmatanga o te whanaketanga, ka puta haere ngā painga o ngā umanga e aro ana ki te kohikohi hangarau i roto i te whakataetae. Ko ngā pūwero hau tīwiri auau rerekē aukume tuturu, ngā pūwero hau tīwiri kōpeketanga e rua-wāhanga, ngā pūwero hau tīwiri kore-hinu, me ētahi atu e tautoko ana i te penapena pūngao, te whakaiti i te kai, te tauira matomato e tū ana i roto i te whakataetae mākete.

I te Whakaaturanga Pūwero o Shanghai 2021, i kitea i muri i ngā tau maha o te whanaketanga, kua tino pakari te umanga pūwero hau o tōku whenua, me ngā momo waitohu me ngā tauira rerekē. Ko ngā hua o te motu o taua momo me ngā waitohu rongonui o te ao kei roto i te kaha whakaputa, te taumata hanga, te kounga hua me te pono. Ki te whakatauritea ki ngā waitohu o te ao, he nui ake te painga utu-whai hua, ā, kua eke te mākete ki te whakataetae katoa. Ko te tere o te whanaketanga o ngā ahumahi matua o raro o ngā pūwero hau pērā i te hinu matū, te mīhini, te maitai, te hiko me te whakarewa i Haina kua whakaoho i te hiahia mōngā pūwero haui te mākete o roto. Hei tāpiri, nā te whakawhiti o te umanga whakapūngao hau o te ao ki Haina, i akiakihia e te tono o te mākete kaweake, kua tere te tipu o te putanga o ngā whakapūngao hau o roto i Haina.
