They tell me to build a warehouse, there arent' any so I build a storehouse, and the storehouse only builds to 75% and then gives up.
What am I supposed to do? ;c ;c ;c

which earth 2150 or 2160?
if earth 2150 use cheats code:
Cheater 1
limit_up 999999

if earth 2160 it is easy to find warehouse (Storage Module) for UCS build Refinery with Storage addition

If anyone gets stuck here aswell. Warehouse is the same thing as storage. And to get past 75 % you need to send your flying ships to the lake and make them gather energy.
