Biogas from sewage

Sweden gets 25% of their energy from biogas, and much of that comes from sewage. Yes, sewage. It powers cars and buses - and costs less than gasoline.

Very cool. Let’s add this to the list of existing, commercially viable technologies that the U.S. has yet to fully (or in some cases even begun to) embrace, along with electricity from manure, ethanol from waste, wind generation, etc.
Then let’s make a list of technologies that are so close to viability as to have real potential to change the energy landscape, including H2 from ethanol, solar nanoantennae, etc.
And consider that 40-50% of all our energy is wasted– and utilities (and other energy companies) are structured to resist conservation.
How can anyone say we “can’t” switch to clean energy? As a nation, we’re not even trying.
