That’s an excellent question! Reusable energy sources are generally more healthy and by that I mean that they don’t produce anything that is dangerous to our health. Also, because of that, it is quite friendly to the environment too, reducing the global warming effect. And, that the fossil fuels that we currently use are running out, so we need to find different ways to produce energy to power our cars, airplanes, TVs, computers, etc.
