>Can a fleet of fighter planes run on electricity, currently? No. >Can you run a supply chain to the front lines of a ground war with electricity? Yes, with cheap solar power and favorable weather condition(alternatively recharge locations which would recharge or repair drones.) Solar powered drones would be more cost-effective than oil-based armies. Air/ground units greatest cost is protection of humans inside, making them expensive and energy hungry. Once the human factor is out, there is no point on being dependent on dense energy sources such as oil or static infrastructure such as rails and roads. The ideal fighting unit is cheap and self-sufficient: something like solar-powered aerial drone armed with particle beam weapon(e.g.ion beam) or area-denial beam weapon powered by wind/solar/hydro. Renewable energy is the future of warfare, like it or not.
