Could Helium-3 really solve Earth's energy problems?

If you watched the movie Moon, you remember Helium-3 as the substance Sam Bell was sending back to Earth, during his onerous three year tenure on the Sarang lunar base. Helium-3 is not a piece of science fiction, but an isotope of helium that really could provide for all of our energy needs in the future. With absolutely no pollution.
Helium-3 is slightly different than the gas that fills birthday balloons. Rather, Helium-3 is a stable isotope of helium that is missing a neutron, with this missing neutron allowing for the production of clean energy. The moon holds a tremendous supply of Helium-3 on its surface, but will Helium-3 really be the answer to our energy problems on Earth?
