Many companies are trying their best to try and cut down their electricity consumption. A good example would be Google. Google consumes a lot of energy. Google searches require the same energy that an 11 watt bulb requires when it's on for an hour. So one can be able to estimate how much energy is required for the Google servers and all other equipment to run. Thus Google has tried to cut their energy costs by developing advanced cooling methods and using energy saving techniques.
Others companies are also following the same trend. For example HP. It presented a paper to the 4th international conference on energy sustainability that describes how HP plans how they will use manure of cows to power their data centres. The title of the paper is design of Farm Waste-Driven supply Side Infrastructure for Data centers.
According to HP, a dairy farm with about 10000 cows produces approximately 200000 tones of manure in a year. The manure produces methane gas. According to research this gas is more detrimental to the environment than carbon dioxide. The manure also pollutes the environment by polluting the rivers and streams. Thus HP using this manure to produce electricity will greatly improve the environment as it gets rid of this pollutant.

Why couldnt we do it with human waste?
This turd looks like it could power a TV!
