I really like the random generation of the world but it does seem to be a touch inconsistent although I can see that as being part of the challenge. I can see myself playing this quite a lot and trying to master it.
I'd like more information, it would be nice to know how many resources you need in order to fully power the next turn and it would be nice to see what tiles will be lost before building a dam.
I think you could genuinely consider further development with this and make a very successful game, the base components are there, an objective system, an entire world and a global warming tracker could turn this into something truly exceptional!
