Each cubic meter (m 3) of biogas contains the equivalent of 6 kWh of calorific energy. However, when we convert biogas to electricity, in a biogas powered electric generator, we get about 2 kWh of useable electricity, the rest turns into heat which can also be used for heating applications. 2 kWh is enough energy to power a 100 W light bulb for 20 hours or a 2000W hair dryer for 1 hour.
Second, the biogas or biomethane generated by the anaerobic digestion process can. replace the use of fossil fuels that generate GHGs. The biogas generated from anaerobic digestion contains about 60% CH4. It is this component, methane (which is also the main component of natural gas), that can produce energy.
