I agree entirely with John Greenberg’s assessment of the specious enthusiasm over the recent “success” of nuclear fusion: It is very far from a success, very far from commercial reality, and very expensive.
I would add that it is also a concept that would require much greater concentration of generation capacity with very large transmission lines to get the power to where it was needed.
The various alternatives currently under development — solar, wind, hydro — are broadly distributed, making it much less likely to result in a huge power outage in case of an attack or a natural disaster.
