Living off the grid used to mean roughing it, but not anymore. Now you can live just as well as any grid home and accomplish all of your goals at the same time.
That definitely includes the winter, and one of the best off-grid methods for heating your home is called biogas.
Biogas is created when organic matter breaks down in an environment devoid of oxygen. The gas created has a very high concentration of methane with a little carbon dioxide and on occasion a small amount of hydrogen sulfide. These other gasses are easily filtered out to produce what is known as clean methane.
What follows here is not be a dissertation or complete instruction, but instead a general overview in case you’re not familiar with the process.
