The king of all energy = trash
People throw things away. They recycle, sure, but consider all the waste in the world the next time you unpack your groceries. Product packaging alone can fill your trash can after one trip to the supermarket.
Garbage goes into landfills, where it decomposes, and creates methane, a gas much more potent than the whipping boy, carbon dioxide. For years, landfills have gotten rid of this gas, which builds up inside, by flaring it off. Burning it, wasting it.
Landfill gas, in which that methane is harnessed and turned into electricity, has lots of potential. For sure, it’s not perfect, but it has a constant source.
And Biofuels Digest notes that even the pope likes waste-to-energy systems.
