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.
Biogas digestion works best at 25 to 35 deg C, 77-95 deg F. One pound (0.45 kg) of cow manure can produce about one cubic foot of gas (28 litres) at around 28 deg C (82 deg F) â enough to cook a day's meals for 4-6 people in India. About 1.7 cubic metres of biogas (60 cubic feet) equals one litre of gasoline (1/4 gallon).
