Of course, you know about wind farms and solar power, right? But did you know that we can generate electricity from our human sewage waste? How about by creating tornadoes? Others have made dance floors that generate electricity for their nightclubs and genetically engineered bugs that actually poop out crude oil!

Here are 9 wacky and wild forms of alternative energy. They might just be the solution we need for a clean energy planet. Let us know which ones you like best!

Poop Power

Let's be honest, no matter how much we humans reduce our waste output there is still one byproduct that's unavoidable: POOP! Though sewage has a history of being converted into fertilizer, that method is now coming under serious criticism due to the amount of pollutants and chemicals found in this mixture. Fortunately, many people are catching on to the amazing potential that the bodily wastes of both humans and animals hold for sustainable energy. People have been using digesters for decades, a machine that through anaerobic digestion uses bacteria to break down the organic material in waste matter, producing methane gas which is then burned for energy. Using the manure from his 600 cows, one Pennsylvania farmer is able to power his farm and a dozen neighboring homes, even selling leftover energy back to the grid. He approximates his savings to be $200,000 a year. One estimate claims that the daily waste from a single person could power a 60-watt light bulb for 9 hours. It's only a matter of time before our cities are powered by poop!
