I te nuinga o te wā, i whakaatu te hunga i rangahauhia i te pikinga ake o te whakaae ki ngā kaupapa here a te kāwanatanga mō te tautoko i te whakatinanatanga o te pūngao rā me ētahi atu pūngao ka taea te whakahou i a rātou e mahi ana ki ā rātou ake whāinga kore tukunga kupenga. I tautokona aua whakaaro e ngā kaiārahi ahumahi i te wā o tētahi hui tukutuku i te tīmatanga o tēnei tau i whakaputaina ai ngā hua tuatahi o te rangahau. Ka waiho te rangahau kia tuwhera ki ngā tāngata o roto i te ahumahi tae noa ki te 14 o Hune.
I whakaahua a Gregory Wetstone, te tumuaki matua o te American Council on Renewable Energy (ACORE), i te tau 2020 hei "tau whakahirahira" mō te tipu o ngā hiko whakahou o Amerika me te tata ki te 19GW o te kaha pūngao rā hou kua tāutahia, me te tāpiri ko ngā hiko whakahou te puna nui rawa atu o te haumitanga hanganga a te rāngai tūmataiti.
"Ināianei... Kei a tātou tētahi whakahaere perehitini e mahi ana i ngā mahi kāore i kitea i mua hei whakatairanga i te whakawhiti tere ki te pūngao ma, me te aro atu ki te raruraru āhuarangi," tana kī.
Ahakoa i Mexico, ko tā rātou kāwanatanga i whakahēngia i mua e te GSC mō te tautoko i ngā kaupapa here e tautoko ana i ngā tipu hiko wahie pūmua a te kāwanatanga i ngā pūnaha whakahou tūmataiti, e matapaetia ana ka kite i te "tipu nui" i roto i te mākete pūngao rā i tēnei tau, e ai ki a Marcelo Alvarez, te kaiwhakahaere o te Rōpū Mahi o Amerika Latina me te perehitini o Camara Argentina de Energia Renovable (CADER).
"He maha ngā PPA kua hainatia, kei te haere tonu ngā tono ki Mexico, Colombia, Brazil me Argentina, e kite ana mātou i te tipu nui o ngā tipu rahi-waenga (200kW-9MW) inā koa i Chile, ā, ko Costa Rica te whenua tuatahi [o Amerika Latina] ki te oati ki te whakakore i te waro i te tau 2030."
Engari i kī te nuinga o ngā kaiwhakautu me whakapiki ake ngā kāwanatanga ā-motu i ā rātou whāinga me ngā wawata mō te whakatinanatanga o te pūngao rā kia noho rite tonu ai ki ngā whāinga āhuarangi o te Whakaaetanga o Parī. Neke atu i te hauwhā (24.4%) o te hunga i uiuitia i kī ko ngā whāinga a ā rātou kāwanatanga e rite ana ki te tiriti. I karanga rātou kia nui ake te māramatanga o te whatunga hiko hei āwhina i te hononga o te pūngao rā nui ki te ranunga hiko, kia nui ake te whakahaere i ngā pūngao hou me te tautoko i te rokiroki pūngao me te whanaketanga pūnaha hiko ranu hei akiaki i ngā tāutanga PV.
