The ABC reports that the ACT Government is going to spend half a million on digging wells into the landfill to extract the gas. Apparently, the gas would power an additional 1000 homes. Currently about 3000 homes are powered this way.
It’s certainly a lot better than letting the biogas drift off into the atmosphere, but I’m not sure of how green it is, or how renewable. (Maybe it’s sort of a browny orangey green?)
Taxpayers may find the $500 000 price tag a bit steep, too. Assuming we were to spend that money on energy, would it be better to spend that on solar or wind power?
