Dam the Gibraltar! ;-)
Totally renewable - and not just hydro, but also solar (which takes care of the water you let in)!
And yes, this has been proposed and is physically possible & it alreadyhappened for geological reasons in the past:

- TomK32 5y agoThere's a far better option with the Qattara depression.
- eru 5y agoCareful there: you might mess with the salt and mineral concentrations in the Mediterranean Sea. And, of course, there's lots of shipping through the straits of Gibraltar that you have to accommodate.
- m4rtink 5y agoNo problem withbsalinity in the most extreme varuants of this - you effectively let the whole Mediterranean Sea evapirate and only let in enough water to keep it this way, effectively making the whole scheme solar driven. That way you can also build multiple dams between island chains and get even more power, before the water eventually evaporates on the bottom most salt pan. Also takes care of shipping. ;-) Although I guess you could build a near shore shipping channel, possibly filled with fresh water from rivers.
- eru 5y ago> No problem with salinity in the most extreme variants of this - you effectively let the whole Mediterranean Sea evaporate [...] Well, then you still need to deal with the salt both as a onetime measure.
