No body knows whats going to happen in 100 year but this is my guess. There probably be more places and species of animals discovered in 100 year,like animal that live on the ocean floor and maybe hidden ruins in the amazon that no one has explored yet. Their could be a way that we can use solar power to make all the electricity in the world,but that would mean some one would have already made solar panels that would be able to crate electricity in the night and also in storms.If we could do that loads of problems in the world would be solved.Right now we can't use solar power as a major power source because of some problems it would have.That is my guess what going to happen in the future.
