So in G1 and continuities like it, a society that can travel across space needs more energy. I can buy that. What I can't swallow is that they would come to Earth and steal our oil, hydro-electric, and other modern fuel sources. This just seems way too simple. It's like taking a train back 1,000 years to steal a team of horses to pull it. I mean couldn't they have built solar collectors around a star? What about building nuclear reactors? It just seems that a society that advanced would have a better and more reliable ways to replenish energy than to steal our primitive resources.
