Innovative energy source

Everything on this planet produces waste, what every species but as we humans are the dominate of the species we produce a lot a waste. As our oil reserves shrinks we must find an alternative source of energy and waste is the best source of energy. It is produced on a daily basis. Its kind of sick to think like that but it could one day become our only hope of survival. It is also renewable so it has some economical advantage. Maybe the conversion of these wastes to renewable energy may cost a lot but in the end it worth the risk.
