Oslo Buses to Run on Sewage 68
Mike writes "Rather than let their sewage go to waste, the city of Oslo recently announced that it plans to cut carbon emissions by converting 80 public buses to run on biomethane generated from raw sewage. The city plans to adapt two sewage plans with the technology this September, and the new biogas buses will be quieter and will cut 44 tones of C02 per bus per year."

It's fortunate that methane is odorless, [wikipedia.org] then.
It's always good to see methane captured and burned into carbon dioxide, since CH4 (methane) is a far stronger greenhouse gas than CO2. On top of that, you can do useful work with the energy—like power a bus fleet—which saves even more carbon emissions.

Gas-driven (not gasoline) buses has been around for at least a decade. It's just that they use a different type of gas.

There are, of course, exceptions. Puente Hills Landfill in LA can generate 50MW. A more typical landfill can generate only a fraction of that.

Yes, but oil-drilling rigs and refineries are often located even farther away, yet gas still get in from them...
