The problem with wind and solar is that they both require extensive spatially distributed energy collection systems, storage to overcome intermittent generation, and complex transmission networks to collect, manage, and distribute the electrical power. It seems unlikely that such can be secured in a world where conflict is steadily increasing, and where a tiny, but significant, percentage of the population is bent on disrupting or destroying infrastructure. On the other hand, nuclear fission and fusion plants are spatially compact and can be located in secured areas near the industrial and residential users connected by short transmission lines. Nuclear plant heat and power can also be harnessed to generate synthetic fuels for transportation and chemical feedstocks as required for military and civilian purposes.
