Actually hydro generation in US and in many other places has recently been falling.
Many factors affecting it - climate change, increased water demands for irrigation and by the population, everything adds up and the trend is negative. I can hardly see these factors reversing, quite the opposite actually.
Expecting hydro to raise its share world-wide is obviously assuming a massive program in the third world. How realistic this is I leave up to you to decide.
Unfortunately I have to conclude your optimism is quite crossing the borders of scientific realism. Same goes for wind - expecting it to surpass both hydro and nuclear based on a track record of 5 years, emerging from virtually non-existent source is... maybe way too much.
I'll let you and Pitt duke it out over the global prospects of hydro, and you and Nick can hash out the potential of wind while you're at it. For now I'm content to split the difference and disappoint both sides.
Significant hydro development may be confined to China and Canada, but I'd bet South America and Russia will put on a push as well. Regarding wind and solar, ¿Quién sabe?
No need for duking - we're gathering evidence, not disagreeing.
LevinK is pointing out that hydro production is falling in some places, although - as your graph shows - it's still growing overall and is currently at its highest level ever. I'm pointing out that substantial hydro potential still exists, even in some developed countries. No conflict.
