Using alternative sources of energy are probably easier to maintain than traditional forms of sources of energy. It does not cost very much to maintain and run a green energy facility so there is a definite long term savings. The fact that they're going to never run out, is probably the best advantage of using renewable sources of energy. The sun has been shining for years, and if it ever ceases shining, we won't need to be worried about anything any longer. We can safely assume that the wind will continually blow.
