People have been using biogas for over 200 years.
In the days before electricity, biogas was drawn from
the underground sewer pipes in London and burned
in street lamps, which were known as “gaslights.” In
many parts of the world, biogas is used to heat and
light homes, to cook, and even to fuel buses. It is collected
from large-scale sources such as landfi lls and
pig barns, and through small domestic or community
systems in many villages.
