While it would be all fine and dandy to get all of our renewable energy from romantic sources such as the sun and the wind, those two methods aren't efficient enough to get the job done. You need to supplement your energy generation with some less savory sources. Might I suggest using your toilet as an energy generator?
That's the idea behind the Benkatine Turbine by Leviathan Energy, designed to go on any pipe that water rushes through, generating energy all the way. This makes it perfect for turning your bowel movements into power to run the refrigerator that holds your food. Just think of it as the circle of life. It's less gross that way.
