Africa is basically untouched with 95% undeveloped. These are using current methods, and true using just those methods wouldn't rise to my claim of filling the future world's entire needs, but it could probably cover the current needs.
This is an interesting study on the total potential, but the final conclusion is only maybe 4-5 times "current" capacity is possible.

Dr.Michael Wysession's, 24-lecture series on energy touched on hydro,and his comment was that,most available hydroelectric sites have already been exploited,leaving no low-hanging fruit.
As mountain glaciers retreat with global warming,we'll be losing streams,rivers,and reservoirs.It's already documented in South America,and elsewhere.Not a good trend with 2-billion more Earthlings in the pipeline.
