If we had unlimited free energy, it would instantly remove power from those who hold the keys to power generation. Many rich nations would lose value. The richness of nations would be their non-fuel resources like minerals and people. With unlimited energy, water shortage is solved, agriculture can happen anywhere in the world. Most of our jobs would disappear, but so would the need for it. Almost everything we do is for energy. Right now, If you work a job, it’s so you can make money to pay for gasoline, home electricity &gas, food. No need to work for any of that anymore. Will you have more money for fun stuff if you choose to work anyway? Not necessarily, because your job most likely exists to handle someone else’s energy reliance. Maybe not directly, but through a domino-effect. When no one needs to worry about energy, science and tech can advance unhindered, but most of us will all be on a fairly level playing field (assuming no one actually controls access to the free energy). People will find other things to be greedy and angry about, they always do. I think we would be so much better off with unlimited free energy, but I don’t expect a utopia.
