None of these problems are the result of using too much energy. Many of them are a consequence of how we produce the energy we have. Most of them can be solved by using even more energy. Maybe you're right that there's some point where we need to restrict energy consumption because the universe is going to run out of hydrogen too quickly if we don't, but we have a lot of problems to solve before we get there, and the solutions to those problems require energy.
