In most of the developed world, the push for renewable energy sources is ramping up. In Canada, many provinces have some type of a "green energy plan" that encourages the development of more sustainable sources of energy. Clearly, this is good news for the planet, but the issue is that existing greener sources of energy (wind and solar power, to name just a couple) often aren't cheap.

The same goes for wastewater sludge. Researchers have played with the concept for a while, but until now, turning wastewater sludge into energy has been a very expensive process. The trouble lies in separating the sludge into its two components: water and biomass. The two components are strongly bound together, so separating them has always proven to be an expensive process. On Thursday, however, University of Nevada researchers said they have found a cost-effective separation method that works.
