Yes, the U.S. uses about 1/4 of the world’s power, which is kind of sad, considering we have less than 5% of the world’s population. No wonder we need to explore renewable energy sources! Most people get the majority of their energy from oil, and we are using it much faster than the Earth is producing it. What do you think would be the best alternative? Solar power? Hydro? Wind? Biofuel? Leave us a comment and tell us what you think!
