Don't rest all your hopes on ITER. Alternative approaches that could well be cheaper and come to fruition a lot sooner include NIF/LIFE, polywell, focus fusion, General Fusion, Tri-Alpha, Helion, levitated dipole, petawatt picosecond laser fusion, and Sandia's new approach to magnetized inertial fusion.
If none of them work, advanced fission designs like LFTR or IFR could be almost as good, with better safety and a hundred times less nuclear waste than conventional reactors.
