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.
To produce 1.0 m3/day of biogas, which typically comprises 60% methane and 40% CO2 and some trace sulphur, one requires the black water from 15 to 20 people, or the manure from three cattle, or 10 pigs, or 1,000 chickens. That cubic metre of gas is sufficient to power a two-plate gas stove for a couple of hours.o produce 1.0 m3/day of biogas, which typically comprises 60% methane and 40% CO2 and some trace sulphur, one requires the black water from 15 to 20 people, or the manure from three cattle, or 10 pigs, or 1,000 chickens.
