I ka makahiki 2021, ua hui pū nā hui 67 i RE100 (ka 100% Renewable Energy Initiative), me ka huina o 355 mau hui e hana ana i ka 100% ikehu hou.

ʻO ka loaʻa ʻana o ka hui honua o nā ʻaelike ikehu hou i loaʻa i kahi moʻolelo hou o 31GW i 2021.

Loaʻa ka hapa nui o kēia mana ma ʻAmelika, me 17GW mai nā hui ma US a me 3.3GW e hele mai ana mai nā hui ma nā ʻāina ʻē aʻe.

ʻAmelika ʻĀkau a me ʻAmelika Hema.

Ua hoʻopaʻa inoa nā ʻoihana ʻEulopa i ka 12GW o ka mana ikehu hou ma muli o ka piʻi nui ʻana o nā kumukūʻai uila ma muli o nā kulekele kinoea e kuhikuhi ana iā Rūsia, ʻoiai ʻo ʻAsia.

Ua ʻike maoli nā ʻoihana i ka hāʻule nui o nā kūʻai mai 2020 a i 2GW i 2021. ʻO ka hapa nui o ka mana ikehu hou i kūʻai ʻia e nā hui honua

lā PV.ʻO Amazon a me Microsoft ka 38% o nā kūʻai honua, a ʻo 8.2GW ka solar PV.

ʻO nā kūʻai PV solar i ʻōlelo ʻia ma luna nei ma waena o ka piʻi ʻana o nā kumukūʻai PV.Wahi a kahi noiʻi a LevelTen Energy, ua piʻi nā kumukūʻai PV mai ka wā mua

2020 ma muli o ka piʻi nui ʻana o ka noi, nā loli macroeconomic, nā pilikia o ke kaulahao a me nā mea ʻē aʻe.Wahi a ka hōʻike hou loa mai LevelTen Energy, ka

Hōʻike ka helu kumukūʻai kūʻai mana kūʻai (PPA) no ka hapahā ʻehā o 2021 i ka piʻi ʻana o 5.7% o nā kumukūʻai PV i $34.25/MWh.
