Flat is pretty easy to change. There's a simple trick they used with making canals for barges back in the day. You dig a 3foot hole and line the sides with a 3foot wall and you get a 6foot deep canal.

I bet spending say 1 billion on a new oil rig will pay back more money than 1 billion on a pumped storage.
