Ground solar has very hard engineering problems associated with it.
Synthetic fuels are either massive CO2 sources or require huge amounts
of energy (or both). They make no sense until power gets down in the
penny a kWh range. Hydro is mostly developed. Wind has well known
serious problems. Nuclear will work if you are willing to build tens
of thousands of reactors.

It is hard to justify the transport system for throughput of less than
a million tons per year. Over a few decades that production rate
displaces most other sources of power.

Having misplaced my ICB (infallible crystal ball) I can't. I can
point you to models which project the peak population at around 7
billion near 2020 and shows declines over the next few decades as high
as a billion people per decade dying from food famines as the direct
result of an energy famine.
(One of the few papers by someone up on peak oil and the singularity.)
