Is there some particular reason why a government needs
to be involved to make it happen?

Why not kill two stones with one bird, and put a large
solar power satellite in a halo orbit around the
Earth-Sun L1? My quick back-of-the- envelope
calculations show that a solar power satellite that
blocks 0.1% of the solar insolation received by the
earth would have a radius in excess of 400 kilometers,
and would generate as much power as all the commercial
nuclear reactors on earth put together 300 times over.
