There's several other countries doing this already. China and Europe have some impressive floating solar arrays. India has been covering their canals with solar. Solar is the future, wether you believe it or not.

At the end of the day, you always need power on demand, not just when the sun is shining or wind is blowing. While these “renewables” can supplement the grid, they almost never are a cost effective complete solution.
