It would make alot of sense for them to have a massive solar farm every now and then given how much free space there is.
A large tower surrounded by a feild of reflective mirrors focussed on a water or molten salt tank.
It would add to the overall infastructure of the world and give us a neat opportunity to run under sea cabling to diffrent sites in the near to end game... a huge underwater facility in each farm meant for generating power, maintinence, directing power and connecting sites.
All undersea cables eaten away by the sharky sharks of course...
