Default Alt. energy sources...

This is mainly my hope for the future, the one impact on this world
that I would gladly accept. I am in no way saying I am as brilliant as
Einstein or other geniuses, I am merely a dreamer, as you might say.
But this is just a background I would like to reveal to aid in your
answering to my question. What new technologies seem to be very
imminent or are already partially acting in the modern-day world? I
have read articles that energy harvested from nuclear fusion may be
commercially available in the next few decades or so. Would this have a
big or relatively small impact? And also solar power. It is ultimately
the main benefactor to our surplus of stored energy on this planet
(except for energy from mass, which is ultimately how the sun is made,
though) , can the amount emitted to Earth keep up with our
ever-increasing demand for that energy? And now to fossil fuels. I have
heard that coal may stay VERY accessible to us for the next few hundred
years, even at this rate, and also there are ways to convert this into
oil, so theoretically, we may be able to stay on the solid-gold Hummers
for the next 300 years :-D. The main problem, though, is extreme
pollution, right? And then to bodies of water. It is already in great
use, as in dams bringing in hydro-electric power. But here is my
conflict, can the tides of the ocean or something be harnessed to make
relatively high reservoirs of water and then let out the water once the
tides descend? Ok, now for my last question which is BY FAR the most
farfetched of them all. Could we put a 'ring' around the sun (I think
that if it were perfectly round, then the gravity would be equal and it
wouldn't go into the sun) that could absorb solar rays and beam them
back to Earth via microwave beams (note that the microwave transfer of
energy is NOT from my mind)? Please try to answer these questions as
thoroughly as you may, and if you don't understand one, please post
that and I will try to clarify it. Thank you :-).
