Nuclear fusion isn't an option because it's not technologically feasible at positive EROEI (that may change someday, but it's basically science fiction now). Positive EROEI on numerous forms of solar is already there and in production. It just can't beat fossil fuel on a cost/power basis. That's an economics problem, not a technical problem.
