Even then I'm not sure they make sense. They've got to compete with
all other alternative sources of terrestrial power. As fossil fuel
prices continue to rise, terrestrial alternatives become more
attractive and investment in them may yield reductions in cost such
that space based power never makes economic sense.
That's possible. But it will take a conceptually different approach,
like solar collectors that grow themselves like Kudzu. It seems
unlikely that earth based solar power will ever get down to 2 cents
per kWh, and that's the target I set for power satellites.
(StratoSolar might be an exception.)
Perhaps advances similar to this?

And there are always other renewable sources, like wind, wave,
hydroelectric, thermal, and etc.
